A control method for automatic operation of ring roller mill

Abstract

The invention discloses a control method for the automatic operation of a ring roller mill, which includes turning on the power supply; detecting the voltage of the power supply, detecting whether the air compressor is turned on and detecting the pressure of the compressed air, starting the pulse, and simultaneously connecting the pulse valve to control the power supply and opening the air supply valve , adjust the air compressor, check whether the bag filter is working normally, check the packaging material receiving device, start the classifier motor, start the fan, open the start damper, start the crushing motor, start the feeder motor, and turn off the feeder motor before stopping. The system detects and controls the fan current, host current and classifier current to be stable, and then shuts off the power supply. The control method of the invention is fully automatic in operation, simple in operation, simple and fast in fault detection, and stable in grinding particle size during shutdown.

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...
