Rod mill stirring rod control method

Abstract

The invention discloses a rod mill paddle control method, which includes the following steps: the rod mill initialization step, including initial monitoring of the feeding amount of the rod mill; the feeding initial step, including setting the variable speed motor to The initial speed is driven by the variable speed motor. After the material passes through the weighing device, the material is conveyed by the belt conveyor from both sides of the rod mill barrel into the rod mill barrel; the feeding speed adjustment step includes monitoring by the weighing device and conveying from both sides. The amount of material entering the barrel of the rod mill is based on the amount of material fed to both sides obtained from the monitoring of the weighing device to adjust the speed of the variable speed motor. The stirring rod control method of the rod mill of the present invention can detect material deviation in time, change the running speed of the variable speed motor to automatically control and adjust the deviation, ensure the balanced state of materials on both sides of the rod mill cylinder, and avoid material imbalance in the rod mill cylinder Accidents such as tape damage may occur.

Description

technical field [0001] The invention is designed in the field of metallurgy, in particular, a control method of a rod mill stirring rod when the 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 under the action of friction and centrifugal force during the operation of the cylinder, and the steel rods are brought to the cylinder by the inner lining plate. After a certain height, due to the action of gravity, the material will be thrown and shed, and the material will be gradually pulverized under the action of impact and grinding. The pulverized material 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 trough. . With the increase of processing capacity, the steel rods in the cy...

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.
