The load on the crusher crushed product particle size and energy consumption, but also affect the normal operation of the stone crusher, it should be timely detection of the load on the crusher. In the multi-stage crushing, generally only detect the load on the control of the final product size in the last paragraph of crusher, this crusher is usually in a closed system, into a quantity ranging from the front a broken segment to the amount and the amount of circulating load.
Detect the last period of the load of the crusher machine main methods are:
(1) direct contact material level indicating crushing cavity material level, that is, knowing the load.
(2) the value of the current in the motor circuit detecting crusher
(3) the feed conveyor belt conveyor belt scales and other weighing crusher
(4) by the calculation of crushing, sieving the cyclic loading of the closed system is derived.
The above four methods can detect a load on the crusher, the first two methods are a direct reflection of the size of the the crusher cavity instantaneous load detection, but also to facilitate timely adjustment, can be composed of the automatic control system for automatic adjustment device. Addition does not directly reflect the load on the impact crusher cavity, the third method also has the advantage of the first two methods, but need to increase the setting of the concentrator; too large granularity of the transportation of materials (materials into the final jaw crusher granularity) 50mm) all kinds of belt scale weighing accuracy is low, it is less choice. The fourth method can only reflect the average load of the crusher in a period of time, can not achieve timely adjustment.
