Material Level Control Is Applied to Cone Crusher

In the three sections of closed circuit crushing operations, the fine crushing operation mainly processes the products after being screened. The efficiency of the crusher is in a pivotal position in the entire process. For the given ore and equipment, the efficiency of the fine crushing cone crusher is mainly determined by feed size, the amount of feeding ore and the size of discharge opening. These factors mutually influence and constraint. If a factor changes, another factor must change accordingly. We must improve the crushing efficiency of the crusher. However, the manual operation is lack of automatic detection and control means. In the production process, it is difficult to adjust the amount of ore conditions timely according to the real-time change so that the load of the crushing is instability. The instability of the ore in the crushing cavity ore affects the normal production. Therefore, the experts of Henan Hongxing Mining Machinery consider that we should use the material level automation control technology to improve the automatic control level in the production process, improve the capacity of the crushing production systems, reduce the granularity of the crushed minerals and save energy.
 After the investigation of the automatic control in the fine crushing process, the experts have detailedly ananalysize the operating conditions and process of the fine crushing. The implementation plan of the material automation control is as the followings. Install the level meter in the ore crushing chamber for the real-time detection of the material level of cone crusher. The variable frequency inverter is used for the ore belt conveyor. The major loop should be installed with current transducer to detect the current of the host of the cone crusher. Change the speed of the belt conveyor by the transducer to adjust the amount of ore to control the material level of the ore in crushing cavity. In this way, the power of the motor will be controlled within the set range.
The transformation programs of the control system mainly use the computer control system to control the cone crusher. You should complete the following specific functions. First, the Frequency converter should be used to adjust the speed of the belt conveyor. Second, in the crushing cavity of the fine crushing cone crusher, the level meter should be installed for real-time detection of the material level of ore of cone crusher. After the transformation, the crushing efficiency is improved significantly.
