It’s almost inevitable for hard rock or hard rock industry to use pre-screening in the crushing circuit. But when crushing relatively soft materials, such as coal and salt, you must carefully analyze the demand for the pre-screening according to the crushing circuit. If you choose a crusher which can bring you one hundred percent of crushing efficiency, you can not only save investment costs but also greatly reduce maintenance costs.

The load detection of impact crusher is a very important part. The detection of the crusher market is mainly detecting the testing technology of the actual amount of ores through the crusher cavity. The load of the crusher affects the particle size and energy consumption as well as the normal operation of the crusher. So it should be timely detected. In the multi-stage crushing, we generally only test the load of the last paragraph which controls the size of final product. This stage of crusher is usually in a closed system. Its materials amount generally includes the cycle load which is from the former crushing segment. The following are the main methods to test the load of last paragraph of crusher. As the professional manufacturer of complete sets of mining machinery, such as stone production line, HXJQ is always doing the best in products and service.

1.Directly using the contact material level to indicate the material level of the crusher cavity, namely knowing its load.

2.Detecting the current value in the motor circuit of the crusher.

3.Using the belt scales to weigh the conveying capacity of the belt conveyor.

4.Deriving by calculating the cycle load of the crushing and screening closed-circuit system.

Hongxing Machinery is a joint-stock enterprise which integrated research, development and sales. We mainly manufacture stone crushing and screening equipment, complete sets of mechanism building sand and industrial grinding equipment. Hongxing provides the crushing and sand making equipment which is selective, reasonable, reliable and cost-effective.
