In the process of gradually increasing the discharge opening, the finished product with qualified granularity can be reduced, the load on the screen is increased, the materials needing secondary crushing are increased, the total transportation distance of the materials can be prolonged, and the energy consumption of the whole production line can be greatly increased. It is therefore an urgent need to find a reliable low-cost discharge opening control.

2. Taking out the model by a taking-out device and calculating: drawing out the abrasion edge track by using a mould remover through dismantling the lining plate, researching the edge track, calculating the average abrasion speed, and estimating the abrasion quantity of the lining plate according to the average abrasion speed multiplied by the service time, wherein the method cannot calculate the lining plate used for the first time and cannot accurately estimate the equipment with large fluctuation of the yield;
3. Taking CN 109282764B as an example, the device and the method for detecting abrasion of the impact crushing lining board use electromagnetic ultrasonic technology to measure the thickness of the lining board, the method is easy to be interfered by a large amount of solid particles in the impact crushing operation working condition, the abrasion data of the lining board can not be provided in real time under the production working condition, the ultrasonic probe has high cost, the average failure-free time is difficult to be ensured in the environment of a large amount of dust and vibration for a long time of the impact crusher, and even if various sealing dustproof vibration reduction means can be used for ensuring, the cost of the impact crusher can be greatly increased.
