Abstract
The utility model relates to a steel ball with slots and belongs to steel balls for steel ball coal mills. The 1-6 slots are formed in the surface of a steel ball body; the width of each slot is 5-10mm, and the depth of each slot is 5-10mm; when one slot is formed in the surface of the steel ball body and is positioned in the maximum diameter position of the steel ball body; two slots are formed in the surface of the steel ball body, respectively positioned in the maximum diameter position of the steel ball, and vertical to each other. The steel ball has the advantage that the structure is novel; when the steel ball is used, coal slag can be filled in each slot, the coal slag exposed out of each slot can take part in the coal milling, and therefore, the wearing of the steel ball is reduced, and the production cost is reduced.
Description
Technical field
The utility model belongs to the employed steel ball of low speed coal mill.
Background technology
The ball type pulverizer system of power plant boiler low speed coal mill mainly is comprised of low speed coal mill, mill separator, cyclone separator, Powder discharging fan etc.Diameter 30 ~ the 60mm of the used steel ball of low speed coal mill wherein, smooth surface, indeformable, do not lose circle, good toughness, but find that through using it is easy to wearing and tearing, has increased production cost greatly.
Summary of the invention
The utility model provides a kind of channel-section steel ball that has, the problem easy to wear that exists to solve existing smooth steel ball.
The technical scheme that the utility model is taked is: it is 5 millimeters ~ 10 millimeters that 1 ~ 6 groove, the width of this groove are arranged on the surface of steel ball, and the degree of depth of this groove is 5 millimeters ~ 10 millimeters.
There is 1 groove on the surface of described steel ball, and this groove is positioned at steel ball maximum gauge place.
There are 2 grooves on the surface of described steel ball, and these 2 grooves lay respectively at steel ball maximum gauge place, and orthogonal.
The utility model has the advantages that novel structure, in use, cinder can be filled in the groove, is exposed at the outer part of groove and can participates in coal-grinding, will reduce like this wearing and tearing of steel ball, has reduced production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model, and 6 grooves are arranged on the surface of steel ball;
Fig. 2 is structural representation of the present utility model, and 1 groove is arranged on the surface of steel ball;
Fig. 3 is structural representation of the present utility model, and 2 grooves are arranged on the surface of steel ball.
The specific embodiment
