An automatic control system and method for an eight-roller crusher

Abstract

The invention discloses an automatic control system and method of an eight-roller type crusher. The automatic control system comprises a roller tooth detection module, a first input module, a second input module, a third input module, a roller adjustment module, a valve adjustment module, a main controller, a hole diameter adjustment module and an alarming module, wherein the roller tooth detection module is used for detecting whether roller teeth are flat or not; the first input module, the second input module and the third input module are used for inputting relevant data; the main controller receives relevant data and transmits execution signals to the alarming module, the roller adjustment module, the valve adjustment module and the hole diameter adjustment module after calculation and analysis; the alarming module, the roller adjustment module, the valve adjustment module and the hole diameter adjustment module receives the execution signals and then execute relevant instructions. The interval between a first roller and a second roller or the interval between a third roller and a fourth roller can be adjusted automatically according to an input interval value, whether the rollers deform or not can be detected, and the size of a discharging outlet and a sieve can 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 system and 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. [0003] The existing crushers can only obtain materials with different diameters by manually adjusting...

Problems solved by technology

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] If you want to obtain materials with different diameters, the existing crusher can only achieve it by replacing the screen; in this way, you need to prepare screens of many sizes, which wastes resources. These stacked 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
