A fully automatic control method for a rolling-type flat-disk-cone-roller crusher

Abstract

The invention discloses a full-automatic control method for a rolling type flat cone roll crusher. The method comprises the following steps: lubricating the rolling type flat cone roll crusher; adjusting the gap between a conical roller part and a hollow shaft sleeve disc part by virtue of a control module according to the types of crushed materials; and executing different material crushing programs by virtue of the control module according to the material types, and executing different feeding programs according to different rotating speeds. According to the method disclosed by the invention, the corresponding crushing programs can be executed according to different types of materials, the quality of the crushed materials is improved, the equipment wear is reduced, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to a crusher control method, in particular to a fully automatic control method for a rolling-type flat-disc-cone-roller crusher. Background technique [0002] The crushing of materials is an indispensable process in metallurgy, mining, building materials, chemicals, ceramics, road construction and other industries, and crushing equipment is an important equipment for realizing this process. Due to the great difference in material properties and structures of materials, there are many types of crushers suitable for various material requirements. [0003] Patent No. ZL201110094654.1 invention patent "Rolling Type Flat Disk Cone Roller Crusher" discloses a new type of rolling type flat disk cone roller crusher, such as figure 1 As shown, it includes a shell 4, the top of the shell 4 is provided with a feed port 1, the bottom of the shell is provided with a discharge hole, and the shell 4 is provided with a crushing device, which inc...

Problems solved by technology

[0008] However, during the use of the rolling type flat disk cone roller crusher disclosed in this patent, the following problems occurred, which seriously affected the normal use of the equipment

[0009] 1. During the use of the rolling type flat disk cone roller crusher disclosed in this patent, there is a shortcoming that the degree of crushing of materials is unstable, which leads to the fact that the crushed materials do not meet the production standards and cannot meet the production requirements, which seriously affects the production efficiency of the enterprise ; At the same time, the serious wear phenomenon of the tapered roller and the hollow shaft sleeve also appeared, which directly caused equipment damage and increased the huge maintenance cost for the enterprise.

[0010] 2. During the use of the rolling type flat disk cone roller crusher disclosed in this patent, the feeding method is completely controlled by the time after the main motor starts (according to empirical values). When the output torque is very high and the output torque is small, the material starts to be crushed, resulting in a sudden increase in load, resulting in a rapid drop in speed, and the equipment cannot run smoothly, which seriously shortens the service life of the equipment.

[0011] 3. During the use of the rolling type flat disk cone roller crusher disclosed in this patent, once the material is stuck, the load will suddenly increase, and the automatic speed of the main motor will drop to zero, resulting in a stalling phenomenon. The "overturning current" generated by the rotation phenomenon will burn the motor

At the same time, after the main motor is blocked, the material conveyed by the conveyor belt to the material inlet is still continuously injected into the crusher. When the internal space of the crusher is filled, a large amount of material is forced to fall outside the crusher, and the fine dust in the material fills the air. polluted environment

In the follow-up maintenance work, it is necessary to clean up the materials spilled on the outside and filling the internal space, which increases the labor intensity of the maintenance personnel and causes serious waste of materials

[0012] 4. During the use of the rolling type flat plate cone roller crusher disclosed in this patent, the crushing mode (including the speed value of the main motor when feeding different materials, the distance between the cone roller part 5 and the hollow shaft sleeve part 8 Gap setting value) is single, and the load distribution of the crusher equipment is unreasonable, resulting in serious energy loss

Especially for different crushed materials, such as coal and coke, the crushing effect is not ideal, and there are shortcomings such as insufficient coal crushing, too large particles, and excessive coke crushing, too small particles
