A horizontal multistage rolling ball mill

Abstract

The invention discloses a horizontal type multistage rolling ball grinder. The horizontal type multistage rolling ball grinder comprises an inner ball grinding barrel, a feeding barrel, a rolling ballgrinding barrel body and an outer ball grinding barrel, wherein the inner ball grinding barrel is arranged in the outer ball grinding barrel; the feeding barrel is welded at one end of the inner ballgrinding barrel; a plurality of stirring bars are welded on a rotating shaft arranged in the inner ball grinding barrel; a primary ball grinding cavity is formed in the inner ball grinding barrel; aplurality of grinding balls are put in the primary ball grinding cavity; the rolling ball grinding barrel body is arranged between the inner ball grinding barrel and the outer ball grinding barrel; aninner ball grinding cavity is formed between the rolling ball grinding barrel body and the inner ball grinding barrel; a plurality of inner grinding balls are arranged in the inner ball grinding cavity; an outer ball grinding cavity is formed between the rolling ball grinding barrel body and the outer ball grinding barrel; and a plurality of outer grinding balls are arranged in the outer ball grinding cavity. The horizontal type multistage rolling ball grinder has the beneficial effects that the plurality of grinding balls are used for impacting materials to carry out primary ball grinding treatment; the inner grinding balls are used for secondary ball grinding treatment; the outer ball grinding cavity is used for secondary ball grinding treatment; the ball grinding effect is good; the time of ball grinding is shortened; the materials with uniform particle sizes are obtained; and the sieving and separation of the materials subjected to ball grinding are facilitated.

Description

technical field [0001] The invention relates to the technical field of metallurgical machinery, in particular to a horizontal multistage rolling ball mill. Background technique [0002] The ball mill is a kind of equipment for crushing materials. Its basic principle is to use the rotating force to lift the steel balls in the drum, and crush the materials through the contact between the steel balls and the materials. However, the current ball milling equipment distributes the steel balls randomly in the cylinder, and converts the kinetic energy during the rotation of the lifting steel balls into potential energy to pulverize the materials. This method is time-consuming and laborious, and the ball milling effect is poor and time-consuming. It is difficult to shorten the ball milling time of the material, and it is difficult to obtain the material with uniform particle size. Therefore, there is a need for a horizontal multi-stage rolling ball mill to achieve multi-stage ball m...

However, the current ball milling equipment distributes the steel balls randomly in the cylinder, and converts the kinetic energy during the rotation of the lifting steel balls into potential energy to pulverize the materials. This method is time-consuming and laborious, and the ball milling effect is poor and time-consuming. A single rotation crushes the material through the contact between the steel ball and the material. It is difficult to shorten the ball milling time of the material, and it is also difficult to obtain a material with uniform particle size.
