Causes of Wear of Ball Mill Liner Board and Improvement Measures

Ball mill is widely used in the metallurgical, chemical, construction, mineral processing and other fields can be seen in the ball mill figure, the quality of the ball mill plays a decisive role in the important components for the liner, its main role is to prevent the cylinder Wear, and therefore one of the most easy to wear parts, the following by the Joyal machinery to explain the reasons for the liner wear and improve the measures.

First, the reasons for the wear of the ball mill liner

Liner on the ball mill has a very good protective effect, can reduce the frequency of friction cylinder, effectively avoiding the material on the ball mill parts damage, then what causes the ball mill liner wear it?

First of all, the wrong installation method will lead to the lining of the force is not enough concentration, leading to fracture;

Second, the manufacturers in the manufacture of ball mill, the choice of liner material is more general, the use of a shorter time, impact resistance and wear resistance is poor, naturally lead to the liner prone to wear problems.

Finally, the liner structure design is unreasonable, will lead to different parts of the uneven degree of wear, different thickness, thin liner is easy to wear.

Second, the ball mill liner wear problems improvement measures

1, select a reasonable steel ball and liner. Ball mill liner and the hardness of the ball to be controlled within a reasonable range, the ball ball diameter set to be reasonable to prevent the liner and the ball between the friction caused by wear and tear intensified.

2, liner material selection to be careful, we must use a relatively high wear resistance of the material, thereby improving the wear resistance of the liner.

3, the newly replaced ball mill liner, according to the nature of the choice of relatively low hardness of the ball, run 1 to 2 months after the increase in the hardness of the liner, the use of relatively high hardness of the ball, which can greatly improve Lining life.

4, strict installation of the quality of the ball mill liner, if the liner and the ball does not match, to swap the liner, after the completion of the installation, to ensure that the bolt tightening to ensure that the liner is running properly.

Ball mill liner has a crucial impact on its performance, in order to avoid the liner problems caused by the production of unnecessary impact, the processing plant must be early prevention, selection of high-quality ball mill equipment.

Master these points to make your cone crusher higher yield

No matter which business, including mining machinery industry friends, no one does not want their own production and then high yield, high efficiency and efficient, because it means that companies will be able to in the shortest possible time to get more benefits. This article shanghai joyal crusher engineer told you some small tips, these small tips can make your cone than the peer crusher users get higher yields, bring better returns.

Cone crusher is a crusher, is a broken production line commonly used in a environmentally friendly equipment, broken than large, high efficiency, low energy consumption, product size uniformity can be used for a variety of ore, rock materials, Widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industry and many other departments.

At the time of operation, the pulley or coupling is driven by the rotation of the motor. The drive shaft and the conical part cause the eccentric shaft to do periodic cyclotron movement under the axis line. In the material from the mouth into the crushing chamber after the eccentric shaft and the mortar wall by the impact of each other extrusion, grinding, rubbing to produce a broken effect. Hydraulic insurance system can be in the machine occurred when the iron failure or boring phenomenon by the hydraulic support and set the top of the cone to eliminate the fault, playing a very good insurance at the same time greatly reduce the maintenance rate and improve production efficiency The

What methods can improve the production capacity of cone crusher to maximize production efficiency?  Shanghai Joyal experts tell you.

1, keep the tight side of the discharge port parameters unchanged

2, try to continue "full" run

3, feeding not too little

4, feed placement need to align the cone into the mouth of the mouth

5, to ensure uniform feeding

6, buffer silo retention to minimize the efficiency of the production line

7, precise grasp of the three design cap of the cone limit

8, to ensure that the crusher in the design of the upper limit

9, monitor and try to ensure the appropriate crusher speed

10, control the feed material in the fine content

11, the height of the feed should not be too large
Joyal machinery production of a variety of cone crusher, complete specifications, and each type of crusher cavity type, the user can according to different needs, choose a different cavity type, in order to better crushing operations. Such as conical broken into standard and short head type, the standard type of feed particle size, nesting particle size is also coarse; short head type crushing cone is steep, feeding particle size is small, is conducive to the production of fine-grained material. Therefore, the standard type is generally used for coarse, medium broken, short head type for, crushing. Users can choose according to their own needs for their own cone crusher.

How to completely solve the jaw crusher dust problem

Jaw crusher as the first choice for ore crushing and processing equipment, in the process of crushing often there will be a lot of dust, spread to the air, not only will damage the ecological environment, but also seriously endanger the health of the staff, so thoroughly Solve the jaw crusher dust problem is the current ore processing plant in urgent need to solve the problem. Joyal machinery as a professional manufacturer of crusher, after market research and analysis, summed up a set of solutions.

Analysis of Dust in Jaw Crusher

To effectively solve the jaw crusher dust problem, we must produce a detailed understanding of the causes of dust, the following we have to look at the specific cause of jaw crusher dust and more reasons.

1, Crusher dust analysis

Jaw crusher dust source mainly from the feed port, outlet and conveyor system. The material to be processed by crusher crushing, broken, the conveyor sent to the next step in the process will produce a lot of dust, the concentration is very high, driven by the air, the dust source will spread to the surrounding, Causing serious dust pollution.

2, the source of dust production reasons

Jaw crusher is not a fully enclosed device, in the feeding process, inevitably produce dust spill phenomenon, making the feed around the mouth to produce a relatively high concentration of dust.

3, the outlet mouth dust reasons

After the broken stone need to go through the discharge port into the conveyor, due to the feed port and the discharge port between a certain gap, there will be part of the stone into the air, while the conveyor in the course of the movement, the stone powder will Then raised, spread to the surrounding.

Second, reduce jaw crusher dust measures

To solve the jaw crusher dust problem, not only need to optimize the local structure of the equipment to improve, but also with a certain amount of external control dust sources, to avoid further diffusion of dust.

1, in the dust source at the set of sealed cover, while the configuration of water and dust collection device.

(1) in the inlet and outlet at the set of two water nozzles, the direction of the nozzle must be reasonable, pointing to the source of dust.

(2) in the crushing chamber moving jaw behind the mouth of the configuration of the vacuum cleaner, with the fan between the connection duct into a scalable pipe, so as to facilitate the daily care equipment.

(3) in the conveyor belt part of the configuration of the water spray device to reduce the dispersion of dust during transport.

2, the chute chute of the tooth plate and other structures to optimize the transformation.

(1) appropriate to reduce the chute chute tilt angle, thereby reducing the material potential potential difference.

(2) increase the number of tooth teeth in the case of other circumstances unchanged.

(3) in time to replace the damaged sieve, so as to avoid the dust caused by material congestion caused by the problem.

The above measures can greatly reduce the jelly crusher dust emissions, for large-scale processing plants, in order to completely solve the dust problem, but also the need for processing plants as far as possible the use of advanced green crusher equipment and technology for production and performance Reliable delivery equipment. Joyal machinery to actively respond to the call of the State Environmental Protection Agency, efforts to develop a more energy efficient, green, environmentally friendly ore processing equipment for the mining enterprises to make a great contribution to the green development.
