Power-free steel ball classification device

Abstract

The invention relates to a powerless steel ball classification device for effectively solving the steel ball classification operation; a classification chute set and a steel ball guide-out groove are vertically and correspondingly connected in an inclined form of high one end and low other end to form an integrated structure; support legs are arranged at the bottom of the steel ball guide-out groove; a steel ball guide-in groove is formed in the outer side above high one end of the classification chute set; one end of the steel ball guide-in groove connected with the classification chute set is an outlet end; a guide-in port baffle plate is arranged at the upper part of the outlet end of the steel ball guide-in groove; an outlet is arranged at the lower part; upwards vertical outer baffle plates are mounted above the upper edges of other three edges, besides high one end, of the classification chute set; the two ends of the outer baffle plates and the two sides of the outlet of the steel ball guide-in groove are in butt joint to form a guardrail structure of the classification chute set for preventing steel balls from rolling outside a classification working surface; and the steel ball guide-out groove is positioned rightly below the classification chute set for respectively guiding out the steel balls with different sizes. The powerless steel ball classification device is simple in structure, convenient for operation, accurate in classification, small and flexible, and improves the working efficiency.

Description

technical field [0001] The invention relates to a power-free steel ball grading device. Background technique [0002] Ball mill is a material fine grinding equipment widely used in ore dressing, metallurgy, cement, coal power and other industries. The steel ball is the medium for impacting and grinding the material in the ball mill. Before the ball mill is used, it is generally necessary to use several steel balls with different diameters for a reasonable ratio according to the input particle size, hardness, product particle size requirements and other reference factors of the material. The steel balls in the ball mill will continue to wear out—taking a ball mill with a loading capacity of 40t used in a bauxite concentrator as an example, an average of 1t of steel balls must be added every week. During the use of the ball mill, it is often necessary to investigate and adjust the ratio of steel balls of different diameters in the ball mill, and then classify the steel balls...

Problems solved by technology

[0003] At present, the classification of steel balls mainly adopts the method of manual sorting, which not only has high labor intensity and low work efficiency, but also has low accuracy of steel ball classification and high mismatch rate.
