Control method of automatic operation of ring roller mill

Abstract

The invention discloses a control method of automatic operation of a ring roller mill. According to the control method, a power source is turned on; voltage of the power source is detected, whether anair compressor is started or not is detected, the magnitude of pressure of compressed air is detected, pulses are started, meanwhile, a pulse valve control power source is connected, an air supply valve is opened, the air compressor is adjusted, whether a bag-type dust collector works normally is detected, a package receiving device is detected, a grading machine motor is started, a fan is started, a wind valve is opened and started, a smashing motor is started, a charging machine motor is started, before shutdown is carried out, a charging motor is closed at first, a system detects and controls currents of the fan, currents of a host and currents of a grading machine to be stable, and the power source is turned off. According to the method, operation is fully automatic, operation is easy, faults can be detected easily and rapidly, and in the shutdown process, the grinding particle size is stable.

Description

technical field [0001] The invention relates to a control method for a ring roller mill, in particular to a control method for the automatic operation of a ring roller mill. Background technique [0002] The ring roller mill is a non-metallic ore crusher. The working principle is that the material is fed into the mill cavity through the feeder, and the material is scattered to the periphery of the circle under the action of centrifugal force, and falls into the raceway of the grinding ring and is crushed by the ring roller. Stamping, rolling, grinding and pulverization. After pulverization, the material is thrown out of the high-pressure centrifugal fan by the disc and sucked into the classifier. The classified coarse particle material falls back and regrinds, and the fine powder enters the bag filter with the airflow for collection and gas-solid separation. The material discharged from the discharge valve is the finished product. [0003] In the existing technology, the ri...
