Control method for stirring rod of rod mill

Abstract

A control method for a stirring rod of a rod mill comprises the following steps: a step of initialization of the rod mill, a material-feeding initial step and a feeding-speed adjusting step; the rod-mill initialization step comprises initially monitoring the feeding amount for the rod mill; the material-feeding initial step comprises setting a variable-speed motor with an initial rotation speed, driving an adhesive-tape machine by the variable-speed motor, and sending a material weighed by a weighing apparatus to a barrel of the rod mill through two sides of the barrel of the rod mill by the adhesive-tape machine; and the feeding-speed adjusting step comprises monitoring the amount of the material sent to the barrel of the rod mill through the two sides by the weighing apparatus, and adjusting the rotation speed of the variable-speed motor based on the two-side feeding amount monitored by the weighing apparatus. The control method for the stirring rod of the rod mill is capable of timely discovering material deviation, changing the running speed of the variable-speed motor to perform automatic control adjustment on the deviation, guaranteeing the balance state of materials at the two sides of the barrel of the rod mill, and avoiding generation of accidents such as adhesive-tape damage and the like caused by unbalance of the material in the barrel of the rod mill.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a method for controlling a rod mill stirring rod when a rod mill pulverizes materials. Background technique [0002] The working method of the rod mill is that the motor drives the cylinder to run through the reduction device. The materials and steel rods in the cylinder are subjected to friction and centrifugal force during the operation of the cylinder, and the steel rod is driven by the lining plate of the cylinder. After reaching a certain height, due to the action of gravity, it will cause throwing and cascading, and the materials will be crushed gradually under the action of impact and grinding. The crushed materials will be discharged out of the cylinder through the central circular discharge port, and the downstream belt conveyor will transport the finished product to the finished product ore. groove. With the increase of the processing capacity, the steel rods in the cylinder ...

AI Technical Summary

Problems solved by technology

Sometimes although the materials on both sides of the barrel of the rod mill are relatively balanced, the system performance cannot fail to meet the design requirements and cannot meet the requirements of the material crushing operation of the rod mill.
