For safety production, the load test of limestone crusher is an important part. The main detection method is to detect the actual ore quantity passing through the crushing chamber of limestone crusher.
In multi-stage crushing process, only test the load of last process, which controls the final product size. This process is usually in the closed-circuit system. Its feed quantity includes the amount from the previous crushing section and the cyclic load.
The main methods to detect the load of the last crusher are as follow.
1. Direct contact material level indicator is used to indicate the material level in the crushing cavity, that is, to know its load.
2. Detect the current value in the motor circuit of the limestone crusher.
3. Calculating the cyclic load of crushing and screening closed circuit system.
