Chit Chat / Five Factors Affect the Production of Jaw Crusher
« on: January 17, 2019, 07:19:08 AM »

<p>  This article is mainly about the key factors affect the production of Ghana Gold Crusher .  Generally speaking, there are a lot of factors affecting the production capacity  of jaw crusher, roughly speaking, five key factors. Now I will cover the five  key factors and offer some solutions for them.</p>

<p>  Material Humidity: When the  material humidity is higher, the material will adhere to the inner wall of jaw  crusher easily, meanwhile, the blocking will be caused easily during the process  of discharging and transportation, which will decrease the sand making  production of jaw crusher. In order to solve this problem, the material humidity  shall be controlled strictly. If the material humidity is higher, we can use the  method of sun exposure or air drying to decrease the material humidity.    Material Components: The finer the material is, the more difficult the sand  making process is, so it is easy for the fine material to influence the  transportation of jaw crusher. Therefore, for the finer material, it is better  to sift them in advance. Sifting the fine material out can avoid affecting the  normal operation of jaw crusher.  Material Hardness: The harder the material  is, the more difficult the crushing process is and the more serious the wear on  equipment is. so for hard material, the crusher will have low crushing speed and  ability.  Material Viscosity: The greater the viscosity of material is, the  easier the adhesion is. It is easy for the material with high viscosity to  adhere to the inner wall of jaw crusher. If not cleaned up in time, it will  affect the work efficiency of jaw crusher, even affect the normal operation of  jaw crusher. Therefore, it is better to choose the crushing material with low  viscosity.  Material Fineness: The higher the demand of fineness is (that is  to say, the thinner the material is), the smaller the crushing ability is.  Generally, it is set up depending on the specific requirement.</p>

Chit Chat / Teach you the way to test vibrating screen
« on: December 19, 2018, 12:00:49 PM »

Proper lubrication and protection plans, as well as bearing state detection work is the focus of the Construction Waste Crusher  bearing highest life. Sharp squeaking noise may be caused due to improper lubrication. Inappropriate vibratory screen bearing clearance can also cause a metallic sound. Dent bearing peripheral track will cause vibration, resulting in a smooth and crisp sound, if the percussion scars caused due to the installation, will also produce noise, this noise will vary with the level of bearing speed. If intermittent noise, then scroll Bo may be damaged, this sound occurs when damage to the surface is rolling out of date, and bearing if pollutants often cause a hissing sound, and serious damage to the bearings will have irregular and a huge noise.

Listen - one of the methods to check whether the vibrating screen is abnormal. We can use the hearing to recognize irregular operation of vibrating screen, such as through electronic auscultation to detect a particular part of the normal noise, which is an experienced operator often to use. If the bearing is in good running condition, vibrating screen will be issued a low hum sound, if issued a sharp hissing sound, squeaky sound, and other irregular sounds, usually shaking screen bearings are in adverse operating conditions.

If it has situation of tremendous noise, it's the time we must replace the bearing immediately. Therefore, a better way such as the use of electronic situation to test equipment, pre-diagnosis of the functioning of the vibratory screen bearings. Compared to the old method, the use of advanced instruments is a more accurate estimate of the vibrating screen bearings situation.

Regular maintenance makes the vibrating screen machine extend shaking life. Instead of using different methods to check out whether the screen equipment has problem, we can make prevention work as early as possible.

Chit Chat / Starting and Stopping Sequence of the Magnetic Separator
« on: November 27, 2018, 03:00:37 AM »

Crusher For Minings, as a kind of strong magnetic device, is widely applied in many industries. There are something worth our attention about the starting and stopping of the machine:

1. First, conduct a comprehensive inspection to the equipment before starting it and find the reason of last failure. If the equipment stops because there is something wrong with the machine itself, we should solve the malfunction first before restarting it. If there is nothing wrong with the machine, we should turn the transmission device several rounds by hand. If it turns flexibly and without being stuck, that means the transmission device is in good condition. If not, we should check the machine and solve the problem.

2. Be excited if the machine functions well. Pay attention not to excite it to the required degree at one time, instead we should improve it step by step. There are there prohibitions here: 1. Start the machine before feeding water. 2. Be excited before starting the machine. 3. Start the machine with load. We could feed materials when the machine and excitation function normally. Pay attention to that wood slag is not allowed in the cylinder. The materials should be smaller than the gap between gears. The strongly magnetic materials are not allowed to enter the machine. Feeding should be even and continuous.

3. The valves of all pipes should be open before starting the machine. Observe if water nozzle is jammed. Check the hydraulic pressure gauge and ensure that the pressure values meet the specified requirements. Then open cooling water pipe and all oil valves before the starting oil pump. After the starting of oil pump, check if the oil pressure is normal and if there is oil leakage phenomenon.

We can see from above, the sequence of starting is: overall checking &ndash; water feeding &ndash; starting lubricating oil pump - starting the coil cooling oil pump - starting the host &ndash; excitation &ndash; feeding ore. The machine stopping can be divided into two kinds: normal stopping and accidental stopping. River sand magnetic separator should be stopped after cleaning up materials inside. The stopping sequence is opposite to its starting sequence.

Chit Chat / Structure introduction of belt conveyor
« on: October 29, 2018, 03:09:16 AM »

Sand Making Machine News consists of two or more pulleys, with a continuous loop of material - the conveyor belt - that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the unpowered pulley is called the idler. There are two main industrial classes of belt conveyors; Those in general material handling such as those moving boxes along inside a factory and bulk material handling such as those used to transport industrial and agricultural materials, such as grain, coal, ores, etc. generally in outdoor locations. Generally companies providing general material handling type belt conveyors do not provide the conveyors for bulk material handling. In addition there are a number of commercial applications of belt conveyors such as those in grocery stores.

The belt consists of one or more layers of material. They can be made out of rubber. Many belts in general material handling have two layers. An under layer of material to provide linear strength and shape called a carcass and an over layer called the cover. The carcass is often a cotton or plastic web or mesh. The cover is often various rubber or plastic compounds specified by use of the belt. Covers can be made from more exotic materials for unusual applications such as silicone for heat or gum rubber when traction is essential.

Material flowing over the belt may be weighed in transit using a beltweigher. Belts with regularly spaced partitions, known as elevator belts, are used for transporting loose materials up steep inclines. Belt Conveyors are used in self-unloading bulk freighters and in live bottom trucks. Conveyor technology is also used in conveyor transport such as moving sidewalks or escalators, as well as on many manufacturing assembly lines. Stores often have conveyor belts at the check-out counter to move shopping items. Ski areas also use conveyor belts to transport skiers up the hill.

A wide variety of related conveying machines are available, different as regards principle of operation, means and direction of conveyance, including screw conveyors, vibrating conveyors, pneumatic conveyors, the moving floor system, which uses reciprocating slats to move cargo, and roller conveyor system, which uses a series of powered rollers to convey boxes or pallets.

Chit Chat / How Can Adjust the One-off Air Pressure of Rotary Kiln?
« on: October 27, 2018, 04:10:07 AM »

The Aggregate Crushing Solution has great influence on the running efficiency and
product quality of rotary kiln. At present, the various air flue burners all
need sufficient one-off air pressure to make sure the one-off air has relatively
high outlet air speed which is conducive to the mixing of the coal powder s and
the one-off air and to the absorption of the second-time air and form recycling
flame. The higher the one-off air pressure is, the bigger the resistance that
the blower needs to overcome will be, which has higher requirement for the
performance of the blower and the electricity consumed by the blower will be
higher, so that it is necessary to reasonably adjust the one-off air

No matter what type of blower, change the air amount, the air pressure will
be changed. As for the question of how to coordinate them both, we need to not
only be careful when choosing the suitable type of blower, take full
consideration on the types of raw coal and the stability of the coal sources and
the output and size of the kiln, but have a good knowledge on the relationship
of one-off air amount and air pressure in the detailed operation and adjustment

The adjustment principle of the one-off air pressure is that the one-off air
amount is not high and the change of the one-off air pressure is not great. As
for this requirement, using frequency conversion technology control motor and
adjusting the air speed through the frequency conversion are the most
reasonable, which not only is energy saving, but has few changes on the property
curve of the blower.

At present the most widely used method for adjusting the air amount is that
using inlet air door to control the centrifugal fan and outlet air to control
the Roots blower. The result of this control is that while the air amount is
changed, the change of the air pressure will be greater. In the practice, even
though the value on the one-off draft indicator can remain unchanged, this value
only means that the static pressure stays the same, the dynamic pressure of the
gas greatly drops with the decreasing of the air amount, which means, the
one-off air speed which brings power to the flame decreases and the burning
speed of the coal powers will slow down. For this reason, though using frequency
changer will increase the one-off investment, it will bring high benefits.

Chit Chat / Cement Production Line Presents Obvious Scale Economy Effect
« on: September 26, 2018, 04:29:32 AM »
<p>Ghana mining machine relation news  is of high technical content, large industrial relevancy, good performance and high efficiency and has become one of the specialized major industries. The advance homogenization technology of cement production line is to use scientific material piling and taking technology during the process to access the raw materials, in order to realize the preliminary homogenization of raw materials.</p>

<p>During the production process of cement, most of the raw materials need to be broken, such as limestone, clay, iron ore and coal, etc. This is about to use cement ball mill equipment. Because the cement ball mill is suffering a long time of severe vibration and its bearings are operating high-loaded, so it is liable to wear and tear. Generally, these bearings should be equipped with retainers, so as to make them have better anti-vibration performance.</p>
<p>One of the raw materials of cement production line -- limestone after being mined has a relatively large granularity and high hardness, so the crushing of limestone takes up an important position among a series of material crushing operations in cement plants. The raw material homogenization system plays the last controlling role in stabilizing raw material ingredients.</p>
<p>The raw material preheating and partial decomposing in cement production line are completed by the preheater, replacing some functions of rotary kiln, to realize the purposes to shorten rotary kiln length, promote heat exchange efficiency, improve the system efficiency and reduce clinker&rsquo;s heat consumption. When building the foundation, we should do the waterproofing work well by paving a layer of sand and gravel cushion for the low-rise buildings, pilling the foundation deeply and filling non-expansive soil.</p>

Chit Chat / Superb Mineral Processing System
« on: March 10, 2018, 04:25:36 AM »
In relation to mineral processing procedure, we're going to to start with think of mineral separation. Mineral separation may be the process to successfully individual helpful minerals from gangue minerals by the use of distinct solutions. Mineral separation is of a great deal concern for ore dressing plants. Effective Ultrafine Mill  processing process is the assure to acquire high-quality concentrate. Without accurate array of mineral processing process ahead of beneficiation, the investment may possibly ultimately guide to failure. Quite the opposite, if deciding upon a superb mineral processing procedure and highly developed agents, it could possibly drastically strengthen the recovery fee of beneficiation, hence considerably expanding economic added benefits for your company.

The dressing plant's choice of your mineral processing output line establishes the quality of the steel separated out. The dressing procedure of ores is composed of a range of separating methods, these kinds of as, the flotation method, gravity separation approach, gravity separation - flotation approach, magnetic separation-flotation course of action, etc. The mineral processing approach is determined by the accredited examination report and required complex and economic comparisons. When important, in addition it desires appropriate modification according for the useful data in the manufactures with identical ore properties.

Flotation process will be the dominating dressing process for nonferrous metallic ores, specifically for copper, guide and zinc ores. Additionally, other kinds of metallic ores and non-metallic ores adopt the flotation system fairly commonly also. The leading distinction amongst the assorted flotation processes lies inside the quantity of the dressing sections, dressing cycle, the refined separation in every single separating stage, situations of scavenging, plus the returning place on the middling merchandise.

Weis occupied from the analysis and generation of various large and medium sized mineral processing products, largely masking magnetic separation device, flotation equipment, crushing tools, grinding equipment, sand-making devices, drying machines, and all sorts of auxiliary tools. Welcome to our business anytime.

Ore Milling Equipment  provides new hope to the slag processing and tends to make an awesome contribution to this subject.

The slag generally consists of calcium, iron, silicon, magnesium as well as a tiny volume of aluminum, manganese, phosphorus and also other oxides. In some parts, the slag also incorporates minimal titanium and vanadium due to the ore containing those people ingredients. Slags are significantly different owing to your many components in steel-making furnace, metal furnace metal smelting and each various phase from the smelting procedure. The application on the crusher has introduced new hope on the slag processing.

The strategy to working with the slag takes advantage of the slag and also the primary slag as uncooked resources. The processing technologies consists of cold abandoned method; hot pour approach, splashing chilly plate process, water quenching strategy. Usually, it makes use of a closed loop generation process that is respectively composed from the process of crushing and screening, vacuum ball milling, classification and wind dry magnetic separation to obtain four high-quality and higher value-added products, which namely means that the steel scrap that has a iron articles bigger than 90 percent of high-quality can be employed for high-grade iron powder iron which can be utilized for a cement and concrete admixture of superior action for high-grade steel slag powder as well as road floor of asphalt concrete surface area layer of steel slag combination. Once the overall manufacturing process done, it can obtain zero emissions slag with no air pollution.

As with the slag processing, Henan Mining Machinery Co., Ltd. specialised in creating all those sorts of kit, like the jaw crusher, hydraulic cone crusher, CS cone crusher, LM vertical mill. The slag is often correctly managed by means of well-designed generation line. The crushing and screening lines use the process of learn, chain, monitoring, which realized a fully automatic generation and the production is more scientific and rational, simpler to use, it's greatly enhanced the efficiency. The output line on the metal slag crushing and delivery technique has mounted dust removing product and took a totally enclosed procedure, which effectively cut down the dust emissions. Your complete creation approach consists by two jaw crusher, a good split CS series cone crusher, five iron removing approach, 5 screening and various system, which kinds the deep processing of steel slag granulation means of a 'three-breaking five chosen 5 screening'. The procedure has the features of superior magnetic selection means, very good restoration of ferrite along with the ferrite content material in tailings has lessened by 17% or less, which drastically improves the active ingredients of metal creation.

Chit Chat / Breaking and Screening Course of action in Beneficiation
« on: February 22, 2018, 03:34:52 AM »
Normally, the crushing approach includes sieving work. The crushing get the job done and sieving operate compose the crushing stage. The crushing and sieving procedure includes overall crushing levels (occasionally the ore washing do the job is included).

The essential crushing and sieving process in dressing plant is similar to the pursuing photo:

Generally speaking, in gold dressing crops and medium and compact dressing crops, the two phase or a few phase crushing and sieving system are generally made use of. The large dressing crops generally utilize the a few stage crushing and sieving system. Even in a few big crops, the 4 phase crushing and sieving method is utilized for the raw ores have substantial size. The ability intake in ore grinding operate is just too big. In an effort to lower the electricity use and reduce the size of your closing crushing goods just as much as you possibly can, the theory of extra crushing and fewer grinding ought to be assured along with the workload of each stage crusher need to be well balanced distribution.

The two stage Ultrafine Mill  method might be classified into two phase open-circuit crushing and also the two phase closed-circuit crushing. The open-circuit crushing will be the crushing solutions don't need to return this phase crushing function for remaining crushed again; the closed-circuit crushing is: once the crushing items are sieved, the goods with unqualified particle size (the merchandise over the screen) will return this stage crushing operate to get crushed yet again. With the two crushing approach, a lot of the dressing crops will use two stage closed-circuit crushing process, that's the two stage crusher plus the sieving device sort the closed-circuit developing. This method will guarantee the particle size necessities of crushing items and can not influence the ball mill grinding function. The two stage open-circuit crushing course of action will probably be employed in some gravity dressing crops and also the crushing items are going to be sent to rod mill. The two phase crushing process is just match with the smaller scale mines underground as well as the production capability is a lot less than 500t per day, for in these plants the wanted total reduction fee is not really large as well as system load of the crusher isn't large.

The a few stage crushing approach is considered the most generally utilized crushing and sieving method in dressing crops. This process is often classified into a few phase open-circuit crushing (pic.c) plus the a few stage closed-circuit crushing. In two stage and a few stage system, every single crushing work is equipped with prescreening to improve the creation potential of crusher and avoid the ore mud&rsquo;s blocking. In a few circumstances, the first and second crushing work does not require the prescreening. For the 3 phase open-circuit crushing approach, the ultimate stage is open-circuit so the particle size requirements of crushing products and solutions are hardly to generally be guaranteed. So the massive dressing plants generally course of action the ore stones with higher water content. The a few stage closed-circuit crushing system is commonly made use of crushing and sieving course of action in big and medium dressing crops. In materials transporting, the crushing merchandise in two stage crushing are mixed along with the products in third stage and sent to closed-circuit vibrating screen perform.
