Polishing apparatus for grinding balls

Abstract

The invention discloses a polishing apparatus for grinding balls, comprising a frame; a polishing disc is vertically arranged on the frame; a feed bucket is arranged at the top end of one sidewall ofthe polishing disc; a turnplate is attached to the other side of the polishing disc; a power device for driving the turnplate to rotate is arranged on the frame; the side, close to the turnplate, of the polishing disc is provided with a polishing passage tube in spiral manner; the polishing passage tube is embedded in the polishing disc; the surface of the side, close to the turnplate, of the polishing passage tube is opened; the open side of the polishing passage tube is flush with the surface of the polishing disc; both the inner wall of the polishing passage tube and the surface, close to the polishing disc, of the turnplate are provided with polishing grains; the start end of the polishing passage tube is arranged close to the center of the polishing disc; the tail end of the polishingpassage tube is arranged at the edge of the polishing disc; both the start end and tail end of the polishing passage tube are opened; a through hole helping communicate the bottom end of the feed bucket and the start end of the polishing passage tube is obliquely arranged in the polishing disc. The polishing apparatus herein has higher polishing speed and higher polishing efficiency.

Description

technical field [0001] The invention belongs to the technical field of wear-resistant ball processing devices, and in particular relates to a wear-resistant ball grinding device. Background technique [0002] As we all know, wear-resistant balls are a kind of crushing medium used in ball mills, widely used in metallurgical mines, cement building materials, thermal power generation, flue gas desulfurization, magnetic materials, chemicals, coal water slurry, pellets, slag, ultrafine powder , fly ash, calcium carbonate, quartz sand and other industries ball mill. Wear-resistant balls are divided into two categories: one is that white cast iron with chromium as the main alloying element is referred to as chromium alloy cast iron, and the cast grinding ball made of chromium alloy cast iron is called chromium alloy cast iron grinding ball; the other is, Cast grinding balls made of ductile iron are called ductile iron grinding balls, in which the matrix structure obtained by heat ...

Problems solved by technology

However, the inner wall of the ordinary grinding box is a simple arc surface, the grinding area is small, the grinding speed is slow, and the grinding efficiency is low; in addition, the powder chips from the grinding cannot be discharged in time, and the powder needs to be poured out after the wear-resistant ball is polished. Chips are separated, increasing the labor process
