Abstract
The utility model discloses a grinding steel ball which comprises a steel ball main body, wherein at least one annular bulge is arranged on the steel ball main body. The grinding steel ball has the beneficial effects that the pressure intensity of the steel ball during a falling process can be enhanced by arranging the annular bulge on the steel ball main body; the working efficiency of the grinding steel ball when being used for grinding coal can be greatly improved due to the design of the zigzag grinding steel ball.
Description
Technical field
The utility model relates to a kind of grinding steel ball.
Background technology
Coal pulverizer is by coal crusher and wears into the machinery of coal dust, and it is the important auxiliary equipment of coal-powder boiler.And grind steel ball, it is necessary a kind of inside stuffing in coal pulverizer.But grinding steel ball in the past, mostly be simple spheroidal, pulverize and to grind efficiency low.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned defect of the prior art, and a kind of grinding steel ball that improves grinding efficiency is provided.
To achieve these goals, the technical scheme that the utility model provides is: a kind of grinding steel ball, include steel ball main body 1, and be provided with at least one projection 2 on described steel ball main body 1, described projection 2 is circular.
Further, above-mentioned a kind of grinding steel ball, be provided with at least one sawtooth 3 on described projection 2.
Further, above-mentioned a kind of grinding steel ball, be provided with some sawtooth 3 along annulus ring Zhou Fangxiang on described projection 2.
Further, above-mentioned a kind of grinding steel ball, the projection 2 on described steel ball main body is 3.
The beneficial effects of the utility model are: a kind of grinding steel ball that the utility model provides, be provided with circular protrusion on its steel ball main body, can increase the pressure that steel ball drops in process, jagged design, more can increase substantially and grind the operating efficiency of steel ball in coal-grinding is used.
