Steel-ball outputting, screening and filling device for ball mill

Abstract

The invention discloses a steel-ball outputting, screening and filling device for a ball mill. The device comprises an electrical control part, wherein the electrical control part is used for partially connecting and controlling an outputting part, a conveying part, a material separating part, a screening part and a filling part. The outputting part comprises an output port disposed in the ball mill. The conveying part comprises conveying pipelines having more than one section which are connected to each other. The output port is disposed corresponding to the head end of the conveying pipelines having more than one section. The material separating part comprises a material separating hopper, a material separating pipeline and a material separating mechanism. The tail end of the conveying pipelines having more than one section is disposed corresponding to the material separating hopper. The material separating hopper is connected to the material separating pipeline. The material separating mechanism which is used for separating steel balls in the material separating pipeline is disposed in the material separating pipeline. The screening part comprises screening equipment and sub-packaging boxes. The screening equipment is connected correspondingly to the material separating mechanism conveying the steel balls into the equipment. The screening equipment is connected correspondingly to a plurality of the sub-packaging boxes used for sub-packaging the screened steel balls of different specifications. The filling part is connected to the sub-packaging boxes and the ball miller. The device is simple in structure, compact in connection, stable in conveyance, high in screening efficiency, high in automation degree, low in labor intensity and low in using cost.

Description

technical field [0001] The invention relates to a device for outputting and screening steel balls for a ball mill. Background technique [0002] Ball mill is one of the high-fine grinding machines widely used in industrial production. There are many types, such as horizontal ball mill, ball mill bearing bush, energy-saving ball mill, overflow ball mill, ceramic ball mill, grid ball mill, etc. The ball mill is suitable for grinding various ores and other materials. It is widely used in mineral processing, building materials and chemical industries. It uses steel balls to grind ore, and produces grinding and peeling through the collision and friction between the steel balls of the ball mill and between the steel balls and materials. , During the operation of the ball mill, due to wear and tear, the weight and diameter of the steel balls are constantly decreasing. In order to ensure the efficiency of the ball mill, it is necessary to add new balls regularly to maintain a certai...

AI Technical Summary

Problems solved by technology

The worn steel balls in the ball mill need to be output and screened, and the steel balls that are not suitable for continuous use should be replaced. Since the ball mill itself does not have the output and screening functions, all steel balls must be cleaned out after the grinding is stopped, and then manually screened. This screening method Steel ball output, cumbersome screening operation, high labor intensity, and low screening efficiency affect the continuous operation of the ball mill

The existing patent No. 200320102659.5 discloses an automatic screening device for steel balls in a ball mill. A liner with sieve holes is provided inside the end cover of the ball mill. There is a ball discharge cavity between the liner and the end cover. When the ball mill is working, the worn steel balls Pass through the sieve holes and fall out from the ball outlet cavity and collect them. The ball mill can screen while working, but the steel balls pass through the sieve holes and the material is easy to pass through the sieve holes, which seriously affects the productivity of the ball mill, and the steel balls continue to impact the sieve holes. , the screen hole is easy to wear and has a short service life. Often the end cover of the ball mill is removed to replace the screen hole, which affects the working efficiency of the ball mill and increases the cost of use.
