Description

A forced fine powder machine

technical field

The utility model relates to a forced fine powder machine, which is especially suitable for the fine powder operation of medium and low hardness minerals (coal).

Background technique

In order to reduce the energy consumption of mineral processing and improve the economic benefits of enterprises, many mineral processing plants focus on improving the production efficiency of the mill, among which more crushing and less grinding is an important technical way to achieve energy saving and consumption reduction. In order to achieve the above goals, it is necessary to control the qualified rate of crushed products, reduce the particle size of the materials entering the mill as much as possible, and realize "more crushing and less grinding, replacing grinding with crushing". Therefore, designing and developing a forced fine powder equipment to reduce the lower limit of the crushing particle size of the existing crushing equipment as much as possible, and at the same time avoid the blockage problem during the crushing process of the moisture-containing material, will help reduce the particle size of the crushed product, improve the grinding efficiency, and save energy. Reduce consumption.

Contents of the invention

Technical problem: The purpose of this utility model is to address the deficiencies in the prior art, and provide a forced fine powder with simple structure, low crushing particle size limit, uneasy blockage of the discharge sieve plate, and improved mill production efficiency. machine.

Technical solution: In order to achieve the above-mentioned technical purpose, the forced fine powder machine of the utility model includes a mounting base, a cylindrical body, a belt transmission mechanism and a temperature controller arranged on the upper part of the mounting base. There is an inner counter-attack block in the body, a discharge port is provided at the bottom of the cylindrical body, and a sieve plate is arranged on the discharge port, and the sieve plate is connected to the temperature controller through a wire. The upper part of the body is inclined with a feed inlet, and the top of the passage of the feed inlet is provided with a feed inlet impact block, and the crushing roller is connected with the belt transmission mechanism through a coupling. A square impact block, the temperature of the sieve plate above the bottom outlet is regulated by a temperature controller.

A fixed block is welded on the crushing roller on one side of the plurality of square impact blocks, a reinforcing rib plate is provided between the fixed block and the wall of the crushing roller, and the fixed block is connected with the square impact block through bolts as a whole.

The temperature adjustment range of the sieve plate above the bottom outlet is from room temperature to 100°C.

The inner wall impact block and the feed inlet impact block are arranged in a tooth shape, and the tooth direction is opposite to the rotation direction of the square impact block.

Beneficial effects: due to the adoption of the above technical scheme, the utility model can reduce the lower limit of the crushing particle size of the existing crushing equipment, and at the same time avoid the blockage problem in the crushing process of the moisture-containing material, which is beneficial to reduce the particle size of the crushed product, improve the grinding efficiency, and save energy. Reduce consumption. When the material to be crushed is first fed into the feed port of the forced fine powder machine, it can be crushed under the impact of the square impact block and the counter block at the feed port. The impact block on the inner wall of the cylinder body is crushed under the forceful impact and rolling action. The finely crushed materials are discharged out of the body through the discharge port with a sieve plate at the bottom of the cylinder body. The undischarged materials are forced to circulate and crush in the crushing chamber until It is discharged from the body through the discharge port. For crushed materials with a moisture content higher than 10%, the controller will heat the sieve plate above the discharge port to avoid blockage of the discharge hole of the sieve plate. Compared with the existing crushing equipment, its structure is simple, the lower limit of crushing and grinding particle size is low, the sieve hole of the discharge sieve plate is not easy to be blocked, energy saving and consumption reduction, and can effectively realize "more crushing and less grinding, and crushing instead of grinding".

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:

As shown in Figure 1, the forced fine powder machine of the present utility model is mainly composed of a mounting base 1, a cylindrical body 2, a crushing roller 4, a belt transmission mechanism and a temperature controller 13; the cylindrical body 2 Installed on the installation base 1, the cylindrical body 2 is provided with an inner wall counter block 3, the bottom of the cylindrical body 2 is provided with a discharge port 8, and a sieve plate 7 is provided on the discharge port 8. The sieve plate 7 is connected to the temperature by the wire The controller 13 is connected, and the temperature adjustment range of the sieve plate 7 above the bottom outlet 8 is from room temperature to 100°C. The crushing roller 4 is arranged inside the cylinder body 2 and is coaxial with the cylinder body. The upper part of the cylinder body 2 is inclined to be provided with a feed port 6, and the top of the channel of the feed port 6 is provided with a feed port impact block 5, and the inner wall counter block 3 and the feed port counter block 5 are arranged in a tooth shape, and the teeth Opposite to the direction of rotation of the square impact block 11. The crushing roller 4 is connected with the belt transmission mechanism through a shaft coupling. The crushing roller 4 is provided with a plurality of square impact blocks 11 at intervals, and the temperature of the sieve plate 7 above the bottom outlet 8 is controlled by a temperature controller 13 regulation.

As shown in Figure 2, the fixed block 9 welded on the crushing roller 4 on one side of the plurality of square impact blocks 11 is provided with a rib plate 10 between the fixed block 9 and the wall of the crushing roller 4, and the fixed block 9 passes through High-strength bolts 12 are connected with the square impact block 11 as a whole.
