Abstract
The utility model discloses a lining plate of a rough grinding cabin of a cement grinding mill. The lining plate comprises a lining plate body, wherein two ends of the lining plate body are the same in thickness, and the upper surface of the lining plate body is provided with a plurality of grooves; the grooves are shaped like circular arcs and extend along the length direction of the lining plate body; the grooves formed in the edge of the lining plate body are shaped like semi-cycle circular arcs; the circular arc radius of each groove is same as the average diameter of a grinding body of the rough grinding cabin; and the depth of each groove is 3/10 of the circular arc radius of each groove. According to the utility model, the lining plate is changed from a corrugated lining plate into an annular groove lining plate, and therefore the problem of short service life of the lining plate is solved, the production energy consumption can be reduced, the grinding efficiency can be increased, and the production cost can be reduced. By using the lining plate, the scrape steel rate of the lining plate can be reduced, the service life of the lining plate can be prolonged, the production cost of a cement plant can be reduced, the grinding and smashing performances of the mill can be improved, and the productivity of the mill can be improved.
Description
Technical field
The utility model relates to a kind of annex of cement grinding mill coarse grinding cabin, is specifically related to a kind of liner plate of cement grinding mill coarse grinding cabin.
Background technology
In the huge revolving equipment in cement plant, the liner plate pattern that is not equipped with the cement grinding mill coarse grinding cabin use of roll squeezer mostly is corrugated liner.This corrugated liner is large because promote coefficient of friction, and breaking capacity is strong, and without grinding dead angle, and it is good and be widely used to pulverize grinding effect.
But corrugated liner is in process of lapping, abrasive body and liner plate surface are to contact, and material easily spills from abrasive body surrounding, and after material is extruded, abrasive body just directly contacts with liner plate, produces heat, makes the abrasion increase of abrasive body and liner plate.Once after the bellows-shaped of liner plate is polished, just need to change liner plate.Be generally about 1 year the service life of corrugated liner, increased production cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of liner plate of cement grinding mill coarse grinding cabin, and it can extend service life of liner plate.
For solving the problems of the technologies described above, the technical solution of the liner plate of the utility model cement grinding mill coarse grinding cabin is:
Comprise liner plate body, the two-end thickness of liner plate body is equal, and the upper surface of liner plate body is provided with multiple tracks groove; Described groove is circular arc, along the length direction of liner plate body, extends; The groove that is wherein positioned at liner plate body edge is half-turn circular arc; The arc radius of described groove is identical with the average diameter of coarse grinding cabin abrasive body; The degree of depth of described groove is 0.3 times of groove arc radius.
Described multiple tracks groove is uniformly distributed along the width of liner plate body.
The upper surface of described liner plate body is provided with four road grooves.
Described liner plate body forms one at length direction near one end and arches upward; The maximum height of portion of arching upward is 100～120mm.
The described portion's highest point that arches upward is of a size of 60～80mm apart from liner plate body center line.
The technique effect that the utility model can reach is:
The utility model changes liner plate pattern into circular groove liner plate by corrugated liner, not only can solve short problem of liner plate life-span, can also reduce energy consumption, improves mill efficiency, reduces production costs.
The utility model can reduce the steel scrap rate of liner plate, increases the liner plate life-span, alleviates the production cost in cement plant, increases grinding and the grindability of grinding machine, improves the production capacity of grinding machine.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the schematic diagram of the liner plate of the utility model cement grinding mill coarse grinding cabin;
Fig. 2 is the profile of Fig. 1.
Description of reference numerals in figure:
1 is liner plate body, and 2 is groove.
The specific embodiment
As shown in Figure 1 and Figure 2, the liner plate of the utility model cement grinding mill coarse grinding cabin, comprises liner plate body 1, and the two-end thickness of liner plate body 1 is equal, and the upper surface of liner plate body 1 is provided with multiple tracks groove 2; Be preferably four road grooves;
The arc radius R of groove 2 is identical with the average diameter of coarse grinding cabin abrasive body, and the depth H 3 of groove 2 is about 0.3R, can make the contact area of abrasive body and liner plate and disengaging resistance reach optimum value;
The portion that the arches upward highest point of liner plate body 1 is 60～80mm apart from the size L1 of liner plate body center line;
The two-end thickness H1 of liner plate body 1 equates, to guarantee adjacent two circular groove liner plate transition well, eliminates and grinds dead angle.
During use, polylith liner plate is used in combination, is positioned at the groove at liner plate body 1 edge and the edge groove of adjacent liner plates (being also half-turn circular arc) and is combined into a complete circular arc, thereby can optimize cast structure, reduce manufacturing cost.
