What factors can decrease the grid type ball mill working efficiency?

The grid type ball mill is a famous grinding machine to do deep processing of non-metal materials. Our grid type ball mill has a wide range of applications in the industries of mining and cement plant.
In the manufacturing and operating procedure of grid type ball mills, maybe you know some common factors affecting the ball mill working efficiency. However,here our experts will make a detailed analysis on grid type ball mill.
The hardness of the products is the first main factor. In general, when the materials are harder, it will be more difficult for grid type ball mills to process them. The difficulty will become greater as the materials turn harder and harder, which will cause much abrasion to the grid type ball mill.
The humidity also plays an important role. In most cases, grid type ball mills will not do well in the process of grinding materials with high moisture content because the great amount of moisture will stick to the interior of the grid type ball mill and will also cause blocking during the delivery process, which weakens the capacity of the grid type ball mill.
The product content is another main factor. If there are too much fine powder materials mixing in the products, we need to screen these materials in advance so that the fine power won’t cling to the inner surface of the grid type ball mill without influencing the material transportation.
The viscosity of the products is also an essential reason influence the grid type ball mill’s working efficiency. If materials are too sticky, they will produce great adhesive force, resulting in the weakening of the working efficiency of the grid type ball mill.

How to maintain the cone crusher?

There is much to do for us about the maintenance of the cone crusher. Though it may takes users much time and labor, the value the maintenance operations bring will make us feel worthy.
Maybe you have some tips for Improving the Cone Crusher Working Efficiency,the daily maintenance work also is one of them.The daily maintenance work according to our experts about cone crusher will be: to inspect the production process to find out and solve problems; to make regular clearance of the crusher in order to prevent materials from gathering; to check the movable parts of the crusher to make sure the triangle belt, gear and the axle sleeve are in the proper position; to replace the lubricating oil frequently to guarantee good lubrication and reduce the abrasion between the interior parts.
Generally, the maintaining work we need to do is involved with the following aspects: timely clearing the crushing cavity, replacing the lubricating oil and check for errors regularly.
First, when we say clearing the crushing cavity, we mean to remove the foreign materials inside the crushing cavity like tree roots, wires and iron wires which can’t be crushed smoothly because of their softness. If we are not able to clear these materials out of the crushing cavity, we will suffer many unpleasing experiences which will cause much damage to the machine.
Additionally, the lubricating oil should be kept clean because once it’s been polluted, the serious abrasion problem will happen to the parts like gears, copper bush and bearings, thus reducing the machine’s service life. Also we need to remember that to check the cone crusher regularly will make us avoid the unnecessary problems and save much energy to maintain it.

High Efficiency Ball Mill

Like there are many factors affecting the crushing force of the jaw crusher,There are also many factors influencing the grinding efficiency of ball mill. As for one ball mill grinder, when processing one mineral, the influencing factors of grinding efficiency include property of grinding media, matching of grinding media, filling ratio of grinding media, ratio of grinding balls to materials, grinding density and feeding granularity. Among them, the influence of some factors is approximately proportional, some nonlinear, some relevant, and such factors as matching filling ratio of grinding media will change along with the implementation of the grinding process and the loss of grinding media, for this reason, it is very difficult to precisely and scientifically calculate the influence relation of every factor. However, there is one influencing factor which is the most direct, clear and most efficient, feeding granularity.

Working efficiency refers to the working amount finished in unit time. For this reason, grinding efficiency refers to the amount of products meeting the granularity requirement of grinding mills in unit time. When the grinding plant, grinding balls and grinding density are the same, the grinding efficiency is mainly related to feeding granularity. Grinding mills are used for processing large materials to products with the required granularity, so that if the granularity of feeding materials is similar to that of required, the working load of grinding mills will be smaller and the working efficiency will be higher.

According to our calculation, when reducing the feeding granularity from 20mm to 5mm, the relative productivity of grinding mills will be improved by about 30%, which means that the ball grinding mill can process 30% more ores in unit time. When such cost as energy consumption and personnel is certain, if 30% more concentrate products can be got in ore beneficiation plant, the increase in economic benefits for the ore beneficiation plant will be huge, for this reason, reducing the feeding granularity is the most efficiency way of improving the grinding efficiency of ball making machine and increasing the benefits of ore processing plant.

Run Different Types of Stone Crusher

 Jaw crusher is the primary crusher, designed with larger capacity to crusher larger materials. the secondary contain impact crusher and cone crusher, they are used to break down the materials which have been through the primary crushing.Do you know the advantage of small stone crushing plant?Can you run different type of stone crusher?No matter which type of machine you are going to use, it is essential to inspect the working condition.
Make sure all parts of the machine is in good working condition and feed the machine lubrication oil. You could determine whether the stone crusher could work smoothly from its working noise. If you find any problem, you should shut down the machine immediately before causing injuries. Generally, several trucks are needed to transfer the crushed materials. Or you could store the materials if you do not need to use them.
The materials fed into the machine should better be dry. Too much moisture would enhance the adhesiveness and you would have to pay too much attention to deal with the blockage. In addition, while you need to check or maintain the machine, you need to turn off the machine first. While stopping the machine, make sure that none of the materials are left inside the cavity.

Use Stone Crusher in a Best Way

There are various kinds of stone crusher products, like impact crusher, jaw crusher, cone crusher and so forth.Even if the most suitable stone crusher machines,we should use the best way for stone crusher,if not,it will get wrong.But,how to use stone crushers in a best way?We can have some ideas as belows:
First of all, for crushing your rock, you should prepare things you will need, like stone crusher, conveyor belt, dump truck and so forth.
Second,it is a good method to check whether the stone crusher is ok or operating properly by listening to it after you turning on the engine of the crusher. Ensure that all crusher components are operating smoothly. If you find there are something wrong, you should shut it down and repair it actually.
Third,  it is necessary and important to inspect all rock crusher parts before your operation. Make any repairs or add lubrication where needed. You should check for broken teeth, bolts and belts and make sure there are no obstructions in crushing cavity. To check it carefully can ensure the work efficiency and reduce the rate of damage and so forth.
Fourth, set the crusher up under a conveyor belt that can carry crushed rock to a pile or dump truck. And adjust the stone crusher opening to accommodate the stone sizes. Your machine will be performing excessive work if you leave the opening too wide actually, which will lead to unnecessary wear on your stone crusher.
Fifth, use a crane or conveyor belt to feed large stones into the cavity of your stone crusher. To achieve smaller rocks, you should feed crushed stones into a secondary stone crusher. You can use a roller crusher to produce gravel-sized rocks if you use a jaw crusher actually.
Last, turn off the power after your work having been done. Inspect its parts to ensure there are no stones lodged in the stone cavity.

Jaw crusher need to be optimized for better use

With the development of the technology,the jaw crusher exists some problems,such as,unconvenience,large cost,and etc. As is known to us all,different functions of different crushers.How to judge the jaw crusher good or not?there are still differences between Chinese manufacturers and the world’s advanced technology that needs us to pay more attention.There exist some deficiencies and flaws in the jaw crusher manufacturing process as follows:
1. The whole crushing procedure is too simple to realize multi-functional breaking. When the jaw crusher works, it will receive many types of materials with multi-phases that are to be crushed. The traditional crushing technology is unable to separate these materials completely from their phases, thus causing over crushing problems which decreases the useful elements and leads to crushing wastes and resource waste.
2. When the compressive strength reaches certain limit during the crushing process, the crushing equipment will consume too much energy without realizing ideal crushing effect.
3. It’s too hard for the jaw crushers to complete the ultrafine grinding process in current technological condition because we need multi-stage processing to crush materials. Since the entire crusher is a giant in size with too much weight, lots of areas and strong supporting base are needed during the installation process.
4. Jaw crushers consume large amount of power and steel materials, so it’s hard to effectively realize energy saving.

What Crushers will Be Applied by Ore Dressing Plants?

In the ore beneficiation or ore dressing production line, the stone crushers or crushing machines are used in the coarse grain crushing stage. According to the equipment crushing methods and working principles, these crushers are mainly divided into four types: jaw crusher, cone crusher, impact crusher and roller crusher.
1.Jaw crusher: it is a very old and widely-applied crushing machine. Its working principle goes like this: the electro motor drives the belt wheel to make the movable jaw up and down through the eccentric shaft; when the movable jaw goes up, the angle between it and the toggle pate is bigger, thus pushing it to get close to the fixed jaw, and at the same time, the materials are crushed or smashed.
2.Cone crusher: it is a continuous ore crushing machine and according to the feed size and the finished product requirement, cone crushers can be divided into rotary cone crusher, medium cone crusher and fine cone crusher. Based on the crushing cavity parallel band length, they are divided into standard type, middle type and short head type one.
3.Impact crusher: it is a new high efficiency and promising machine crushing machine featuring small size, simple structure, high crushing ratio, low energy consumption, high yield, evenly product particles and selecting crushing function.
4.Roller crusher: it is powered by the V-belt pulley on the motor, and through a couple of middle reducers, it drives the fixed roller to spin and relying on the couple of long gear pulley installed on the other end of the fixed roller, the dynamic roller is driven. The two rollers are moving towards each other to squeeze materials.

Factors Affecting the Crushing Force of Jaw Crusher

Crushing force is one of the main parameters of primary jaw crusher, and analyzing crushing force has an important guiding meaning to improving the crushing effect of stone jaw crusher. Determining the crushing force of a jaw crusher needs to analyze the influencing factors which will be explained here in detail.

1. The mode of action on materials
The crushing of ores and rocks generally adopts mechanical crushing method, and the modes of action of crushing machines include crushing, splitting, bending, grinding and impacting. As for hard ores, it is suitable to use bending and impacting for crushing; as for crisp ores, bending and splitting will be good; as for tensile and sticky materials, it is better to adopt grinding method for crushing. Jaw crushing machine mainly crushes materials with crushing and bending, and the difference of mode of action on materials determines the crushing force.

2. The motion of movable jaw
The trajectory distribution of the points on movable jaw is relatively reasonable and its horizontal throw gradually decrease along the jaw plate of movable jaw, which can just satisfy the requirement for increasing the amount of compression when crushing large materials, and the lower end of movable jaw will move downward in the discharging process.

3. The property of materials
The properties of materials include stickiness, hardness and compression strength. Different materials have different compression strength, and the crushing force produced is also different, for this reason, the computational formula of crushing force of PE jaw crusher should contain the parameters of mechanical property of materials. In addition, the particle shape of materials will also influence the crushing force of Mini jaw crusher.

4. The movement of tooth plate
When the movable tooth plate moves, the stress on the tooth plate is free-running on the upper and lower part, and they are opposite in some working areas. The crushing process will produce crushing force, but the discharging process will not produce crushing force, for this reason, the crushing force in different working areas is different.

Analyzing the influencing factors of crushing force of jaw crushing machine is conducive to setting up the computational formula of its crushing force, as it is the foundation of the strength and stiffness of the spare parts of this crushing equipment and has great significance to ensuring normal operation of the crusher and extending its service life.

How can Mining Industry Reduce Energy Consumption?

After years’ research and development by our experts, our company has designed and made the new generation of grinding machines, namely the energy saving ball mills.

Our ball mill can not only finish the grinding process in a short time with little power consumption, but also can realize the multiple stage crushing and grinding processes, thus reducing workers’ labor intensity.
Our ball mills can help customers solve many negative problems as follows:
1.Most ball mills consume too much energy and work with low efficiency, which leads to serious energy and material wasting problems.
2.We can’t ignore the issue of ball mills’ high production and operation cost. When the ball mill runs, the grinding device impacts and grinds the materials in the mill which is ground at the same time to certain extent. Abrasion will also happen to the mill’s other components.
3.The domestic market doesn’t have a greater amount of demand for the ball mills, compared with the foreign developed mining machinery industry.
Knowing about the problems listed above that may lead to the companies’ stagnancy, it’s time for us to take measures to change or improve the current developing situation of the ball mills. The most effective we can do is to think of innovative ideas to reduce the energy consumption and production and operation cost of the ball mills.
In the modern times of information development, all mining machinery enterprises are trying to make innovation on their own to increase the competitiveness of their products and services. They all are aware of the significance of the technological innovation.
