A control method for feed regulation of a conical sand mill

By combining the PLC controller and the rotary feeder, the feed rate of the cone crusher can be precisely adjusted and the material can be distributed circumferentially. This solves the problems of uneven wear and unstable operation caused by uneven feeding, and improves the stability of the equipment and the quality of the products.

AI Technical Summary

Technical Problem

The existing feeding method cannot guarantee a uniform distribution of feed in the circumferential direction in the cone crusher, resulting in uneven equipment wear, unstable operation and unstable product particle size, and it is difficult to adapt to changes in incoming materials and adjustments to equipment operating conditions.

Method used

The PLC controller acquires the operating status information of the cone crusher, adjusts the opening degree of the opening and closing parts, and combines with the rotary feeder to achieve precise control of the feed rate and circumferential material distribution, thus constructing a control link of status acquisition, opening degree conversion, execution adjustment, and feedback correction.

Benefits of technology

It achieves continuous and adjustable control of the feed rate, improves the circumferential distribution of materials in the cone crusher, reduces uneven wear and unstable equipment operation, and improves the stability of the equipment and product quality.

Abstract

The application discloses a control method for feed regulation of a conical sand making machine, which is applied to an electric discharge control valve system and a rotary feeder arranged between a hopper and a feed inlet of the conical sand making machine. The method comprises the following steps: obtaining running state information of the conical sand making machine; a PLC controller receives a remote 4-20mA analog signal and converts the signal into an opening-closing piece target opening signal; the running state information is compared with a preset threshold value to determine the running state of the conical sand making machine; a control signal of an electric actuator is generated according to the target opening signal and the running state determination result, the valve rod drives the opening-closing piece to move in the valve body to regulate the material passage opening; the adjusted material enters the rotary feeder and is dispersed along the circumferential direction of the feed inlet, the running state information is obtained again and is adjusted again. The method can match the feed quantity with the running state, improve the uniformity of the wear of the crushing wall and the mortar wall, and improve the running stability.
