Anti-oxidation ball mill

Abstract

The invention belongs to the field of grinding equipment, and particularly relates to an anti-oxidation ball mill. The anti-oxidation ball mill comprises a rack and a drum, and a plurality of grinding balls are placed in the drum; the rack is rotatably provided with a rotation shaft, the rotation shaft is fixedly provided with the drum, and the drum is provided with a material door for feeding and discharging; a support is arranged on the top of the rack, a cross bar is fixedly installed on the top of the support, a feeding hopper is movably installed on the cross bar, an inertia hammer is fixedly installed on the cross bar, a discharging door matched with the material door is arranged at the bottom of the feeding hopper, and multiple groups of oblique grooves distributed on the inner wall of the feeding hopper in a surrounding mode are formed in the inner wall of the feeding hopper; openings of the oblique grooves are obliquely upward, and sodium nitride powder is contained in the oblique grooves. According to the anti-oxidation ball mill, metal materials can be prevented from being oxidized, and the properties of the metal materials are guaranteed.

Description

technical field [0001] The invention belongs to the field of grinding equipment, and in particular relates to an anti-oxidation ball mill. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed. It is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizers, non-ferrous metal beneficiation and glass ceramics and other production industries. [0003] The ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging materials, and a grinding head. The cylinder is a long cylinder, and the cylinder is equipped with grinding bodies. in the barrel. The material is selected according to the particle size of the grinding material, and the material is loaded into the barrel through the hollow shaft at the feed end of the ball mill. When the barrel of the ball mill rotates, the grinding body is attached to the liner of the barrel due to inertia, ce...

AI Technical Summary

Problems solved by technology

[0004] The problem existing in the prior art is: during the working process of the ball mill, some metal ores or metal products are ground and pulverized, the powder formed after the ball mill has a larger surface area than the original workpiece, and the contact area with the air becomes larger, making these metals Ore oxidizes quickly after grinding and loses its properties
