Automatic control method for eight-roller type crusher

Abstract

The invention discloses an automatic control method for an eight-roller type crusher. A roller tooth detection module is used for detecting whether roller teeth are flat or not. A first input module, a second input module and a third input module are used for inputting relevant data. A main controller receives the relevant data and transmits execution signals to an alarm module, a roller adjusting module, a valve adjusting module and a pore diameter adjusting module after computational analysis. The alarm module, the roller adjusting module, the valve adjusting module and the pore diameter adjusting module receive the execution signals and further execute relevant instructions. According to the automatic control method for the eight-roller type crusher, the space between a first roller and a second roller or the space between a third roller and a fourth roller can be adjusted automatically according to the input space value; whether the rollers are deformed or not can be detected, and the size of a discharging outlet and the size of a screen can further be adjusted according to the input value.

Description

technical field [0001] The invention relates to the field of control systems, in particular to an automatic control method for an eight-roller crusher. Background technique [0002] Crusher is a very common equipment in mines, which can crush ore into required size. In the existing roller crusher, if it is necessary to crush the ore that is too large into small pieces, a large toothed roller surface crusher cannot be used. Due to the need for strength, the teeth on the toothed roller surface cannot be used Small teeth, but the general roller crusher does not have enough strength to crush large ore, the number of crushing is small, and the crusher needs to replace components frequently, the cost of use is high, the work efficiency is low, and the obtained crushed ore The powder rate of the block is high, the size is uneven, and secondary processing is required.

In the existing roller crusher, if it is necessary to crush the ore that is too large into small pieces, a large toothed roller surface crusher cannot be used. Due to the need for strength, the teeth on the toothed roller surface cannot be used Small teeth, but the general roller crusher does not have enough strength to crush large ore, the number of crushing is small, and the crusher needs to replace components frequently, the cost of use is high, the work efficiency is low, and the obtained crushed ore The powder rate of the block is high, the size is uneven, and secondary processing is required

[0003] The existing crushers can only obtain materials with different diameters by manually adjusting the distance between the rolls. Although the cost is low, it is troublesome and prone to control errors resulting in poor handling;

[0004] In order to obtain materials with different diameters, the existing crusher can only achieve it by replacing the screen; in this way, it is necessary to prepare a lot of screens of accurate size, which wastes resources. These piled up screens occupy an area and are expensive;

[0005] When the material is poured into the feed port, due to the strong impact of the material falling, it is easy to deform the teeth on the roll; and the existing crushed discharge port is a fixed size, when you want materials of different sizes, due to the It cannot be realized due to the limitation of the feed port
