What are the installation requirements and precautions for bulkhead plates for ball mills?

The former towering Aston is debunked.

1. The base of the bulkhead plate should be padded and close to the cylinder, and the plane of the bulkhead should be perpendicular to the center line of the ball mill. Special attention should be paid to the partition board, grate board and central round plate of the baseball grinding first bin should be kept flat and vertical, otherwise unevenness will cause messy sticks. The verticality of the bulkhead plate should be checked at a 90° return point.

2. When installing the compartment plate grate, the gap between the grate plates shall not be greater than the width of the grate, and the general requirement is less than 5mm.

3. Check the size and quality of the partition plate according to the drawings before installation. The surface of the bulkhead plate, especially the joints, must be smooth, and there must be no sand hole cracks, etc. It is best to lay it on flat ground and check it with a compass, and the position, size, and distance of each screw hole must correspond to each other.

4. During installation, attention should be paid to the burrs and mortar on the edge of the screw hole pit or screw hole to ensure that the bolt head is flat and settled.

5. The conical grate hole of the compartment plate grate plate is directional, do not reverse it during installation, the correct direction is that the small end of the conical hole is the feeding end, and the large end is the discharging end, so as to avoid the material blocking the grate hole.

Ball mill bulkhead plates utilize grate hole sizes or arrangements.

The basic functions of the bulkhead are silos, filter materials and ventilation, and the purpose of silo is to further plan the functions of each silo.

The first task of the compartment unit is to meet the requirements of the compartment. The steel balls of different diameters in the mill are separated to adapt to the reasonable principle of using large balls for coarse grain grade and small balls for fine grain grade in the material grinding process. At the same time, coarse particles are jammed to prevent them from moving from the front to the back.

Once the coarse particles run to the back warehouse, because there is no big ball in the back warehouse, it cannot be crushed and will run coarse, affecting the production and quality.

The bulkhead plate of the ball mill uses the size or arrangement of the grate hole to sieve the material, which can prevent large particles from entering the area with weak impact force. Otherwise, the uncrushed material blocks are piled up, which seriously affects the grinding effect, or is not finely grinded, resulting in unqualified product fineness, and preventing large particles of materials from channeling to the discharge end.

The size or arrangement of the grate holes of the bulkhead plate can control the flow rate of the material during the grinding process in the mill. The grate hole of the partition plate determines the filling degree of the material in the mill, which controls the grinding time of the material in the mill and the flow rate of the material in the mill. In the grinding process of the bulkhead plate of the ball mill, the size of the material decreases in the direction of the grinding tail, and the grinding body is required to start to be dominated by impact, and gradually transition to the grinding effect to the direction of the grinding tail.

The smaller the size of the grinding body, the greater its number, and the larger the surface area of the grinding body, the stronger the grinding effect. Therefore, professionals require that the size of the grinding body also decrease in the direction of the grinding tail. Bulkhead plates are used in multi-chamber mills to separate grinding bodies of different gradations or shapes.

The analysis and selection of materials of the ball mill is mainly the function of the bin plate, and the main role of the bin plate for the ball mill is as follows.

1. Separate the grinding body.

Those who have used the ball mill know that the ball mill ball specifications of each bin of the ball mill are different, this is because the role of each bin is different, and the function of the compartment plate is to divide the grinding body according to the situation of each bin. The average size of the grinding body in each bin is gradually reduced from the coarse grinding bin to the fine grinding bin, so as to meet the needs of large grinding body grinding large materials and small grinding body grinding small materials, and better play the grinding role of grinding body.

2. Control the flow rate of abrasive in the mill.

The gap in the bulkhead plate determines the final flow rate in the ball mill. Efficient grinding of the material is guaranteed.

3. Analysis of materials.

It can prevent excessive particles from entering the area with weak impact force, otherwise it will cause the accumulation of materials that cannot be crushed, which will seriously affect the grinding effect of the ball mill, or the grinding of unrefined materials will cause the fineness of the product to be unqualified.

Ball mill. The role of the bulkhead plate is very large, it is an important part of the output of the ball mill and the effect of the finished product, the ball mill produced by Henan Yigong Machinery is a new product, and the bulkhead plate of the ball mill is mainly a sorting material, including:

1. The function of the compartment plate is different, according to the situation of each warehouse, put.

Abrasive body. to divide it. Keep the average size of the grinding body in each bin by.

Coarsely ground. The silo is gradually reduced to the fine grinding chamber to meet the needs of grinding large materials for large grinding bodies and grinding small materials for small grinding bodies, so as to better play the grinding role of grinding bodies.

2. Control the flow rate of the abrasive in the mill, and the gap on the compartment plate determines the flow rate in the ball mill. Efficient grinding of the material is guaranteed.

3. The bulkhead plate of the ball mill can prevent the excessive particles from entering the area with weak impact, otherwise it will cause the accumulation of materials that cannot be crushed, which will seriously affect the grinding effect of the ball mill, or the unground materials will be grinded, resulting in unqualified product fineness.

The role of the ball mill bulkhead and the function of classifying the ball mill bulkhead, on the one hand, isolate the size of the grinding body and adapt to the size of the material to be crushed, and prevent the large particle material from escaping out of the discharge end, on the other hand, in order to control the movement speed of the material in the mill, the bulkhead can be divided into a single-layer bulkhead plate and a double-layer bulkhead. There are two classifications of ball mill bin plates: a single-layer bin plate, and a single bin is an overflow discharge type that relies on the surface difference of the grinding material to make the material.

It consists of a grate plate and a center plate. B double-layer compartment has the function of forced material flow, which is not affected by the difference in material level, and is currently used in the form of FLS combined double-layer compartment plate. Its structure is composed of coarse sieve plate, blind plate, support plate, front plate, fine sieve plate, etc.

The bulkhead plate of the ball mill is mainly used to grind ore in sections with a mill, which is generally divided into coarse grinding, medium grinding and fine grinding, and it is to block the flow of large materials and steel balls to the next bin!
