Method for reducing load of rod mill and abrasion to inner chamber of rod mill

Abstract

The invention relates to the technical field of application of a rod mill, and discloses a method for reducing the load of the rod mill and abrasion to an inner chamber of the rod mill. The method comprises the following steps: (1) additionally arranging an electromagnetic band type iron separator and transforming magnetic separation equipment; (2) improving the stability of a steel rod; (3) manufacturing a steel slag screening device and sorting and smashing steel slag; (4) adjusting the metal grade and a transmission device; (5) storing and managing the metal after recovery; and (6) checkingthe modification result. According to the method for reducing the load of the rod mill and the abrasion to the inner chamber of the rod mill, the steel slag is conveyed to the interior of the screening device for primary crushing and secondary crushing before entering the rod mill, so that the steel slag is prevented from excessively abrading the steel rod when entering the rod mill and the consumption of the steel slag is reduced, and the effect of reducing the material consumption is achieved; and due to the fact that the metal grade and the transmission device are adjusted, matched equipment of a belt conveyor can have good abrasion resistance, and accordingly the problems that the consumption of a grinding rod and an auxiliary plate of the rod mill is high and the abrasion of the matched equipment of the belt conveyor is serious are effectively solved.

Description

technical field

[0001] The invention relates to the technical field of rod mill application, in particular to a process method for reducing the load of the rod mill and the wear of the inner chamber of the rod mill. Background technique

[0002] Rod mill is a kind of mill in which the grinding body in the barrel is a steel rod. Rod mill is generally of wet overflow type and can be used as a primary open circuit grinding. It is widely used in artificial stone sand, mineral processing plants and chemical industry. The primary grinding of the power department of the plant, the mill is mainly composed of a motor, a final reducer, a transmission part, a cylinder part, a main bearing, a slow transmission part, a feeding part, a discharging part, an annular seal, jet lubrication of large and small gears and The main reducer is composed of parallel shafts and hard tooth surfaces. The rod mill is an asynchronous motor connected with a small gear through a reducer, which directly driv...
