Abstract
The utility model relates to a kind of end cover of ball mill inner ring liner plate unit, comprise fan-shaped liner plate main body, it is characterized in that: described fan-shaped liner plate main body root is provided with for covering the edge of a wing to, ore discharge sleeve seam end, the chord length that the cross section on the described edge of a wing is circular arc and circular arc cross section equals the width of described fan-shaped liner plate main body root, and the outer surface on the described edge of a wing has the gradient of extending along ball mill axis direction.It is simple in structure, end cover of ball mill and main shaft axle journal are played a protective role simultaneously, fundamentally solved existing ball mill to, ore discharge sleeve seam is easy to wear and the ball mill main shaft axle journal inner wall abrasion that causes, shorten the end cap problem in service life.
Description
Technical field
The utility model relates to ball mill parts, particularly a kind of end cover of ball mill inner ring liner plate unit.
Background technology
Ball grinding machine lining board mainly plays the effect of protection end cover of ball mill and cylindrical shell, and protection ball mill main shaft axle journal is mainly to, ore discharge sleeve.The similar taper shape of end cover of ball mill, on end cap, the liner plate of innermost circle is that similar fan-shaped polylith liner plate unit spliced forms (referring to Fig. 4,5), liner plate unit is along the circumferential direction uniformly distributed, thereby plays the effect of protection end cover of ball mill inwall.In ball mill continuous operation process, end cap liner plate is constantly wearing and tearing under the continuous erosion of ore pulp, especially give, the seam position of ore discharge sleeve more easily weares and teares.Once give, the seam position of ore discharge sleeve weares and teares, and will cause the gap of sleeve and hollow spindle axle journal inwall to enter ore deposit, will cause journal wear even to damage if can not find in time.And main shaft is the position that ball mill need to be laid special stress on protecting, main shaft axle journal and end cap are an integral body, once journal wear is serious; unrepairable, need to change whole end cap, has shortened the service life of whole end cap; cause the wasting of resources, and spare parts cost expense is high, the process-cycle is long.
Summary of the invention
The purpose of this utility model is for a kind of end cover of ball mill inner ring liner plate unit simple in structure, that end cover of ball mill and main shaft axle journal are played a protective role is provided simultaneously, fundamentally solve existing ball mill to, ore discharge sleeve seam is easy to wear and the ball mill main shaft axle journal inner wall abrasion that causes, shorten the end cap problem in service life.
The technical solution of the utility model is:
A kind of end cover of ball mill inner ring liner plate unit, comprise fan-shaped liner plate main body, it is characterized in that: described fan-shaped liner plate main body root is provided with for covering the edge of a wing to, ore discharge sleeve seam end, the chord length that the cross section on the described edge of a wing is circular arc and circular arc cross section equals the width of described fan-shaped liner plate main body root, and the outer surface on the described edge of a wing has the gradient of extending along ball mill axis direction.
Above-mentioned end cover of ball mill inner ring liner plate unit, the angle of described edge of a wing outer surface and ball mill axis than describedly giving, the angle of ore discharge sleeve lining and ball mill axis is large, so that axially there is certain slope on the edge of a wing.
Above-mentioned end cover of ball mill inner ring liner plate unit, the gap of described edge of a wing inner surface and ball mill main shaft axle journal inwall is greater than the thickness at the described seam position to, ore discharge sleeve, so that install.
The beneficial effects of the utility model are:
1, at fan-shaped liner plate main body root, be provided with the edge of a wing, for covering, give, ore discharge sleeve seam end, effectively protection contact with main shaft axle journal inwall to, ore discharge sleeve seam position is not washed away by ore pulp and is produced wearing and tearing, thereby reach the object of protection main shaft axle journal inwall, prolongation is given, the service life of ore discharge sleeve, it is the service life of whole end cap, simple in structure, end cover of ball mill and main shaft axle journal are played a protective role simultaneously, fundamentally solved existing ball mill to, easy to wear and the ball mill main shaft axle journal inner wall abrasion that causes of ore discharge sleeve seam, shorten the end cap problem in service life,
2, the chord length that the cross section on the edge of a wing is circular arc and circular arc cross section equals the width of fan-shaped liner plate main body root, each liner plate unit is after the evenly distributed installation in axle center, guaranteed to give, ore discharge sleeve circumferencial direction all covers by the edge of a wing, protect the sleeve seam of whole circumferencial direction by ore pulp, not washed away, and do not interfere between the adjacent edge of a wing;
3, the outer surface on the edge of a wing has the gradient of extending along ball mill axis direction, though ore pulp be washed into the edge of a wing also can be under Action of Gravity Field, in rotary course, from flowing down, can not touch the seam position to, ore discharge sleeve, strengthened protective effect.

Fig. 1 is scheme of installation of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the side view of Fig. 2;
Fig. 4 is the structural representation of former end cap inner ring liner plate;
Fig. 5 is the side view of Fig. 4.
Sequence number explanation in figure: fan-shaped liner plate main body 1, the edge of a wing 2, give ore deposit sleeve 3, seam end 301, ore discharge sleeve 4, seam end 401, ball mill axis 5, ball mill main shaft 6.
The specific embodiment
As Figure 1-3, this end cover of ball mill inner ring liner plate unit, comprises fan-shaped liner plate main body 1, and described fan-shaped liner plate main body 1 root is provided with for covering the edge of a wing 2 to, ore discharge sleeve 3,4 seam ends 301,401.The chord length that the cross section on the described edge of a wing 2 is circular arc and circular arc cross section equals the width of described fan-shaped liner plate main body 1 root.The outer surface on the described edge of a wing 2 has the gradient of extending along ball mill axis 5 directions, in the present embodiment, the angle of the described edge of a wing 2 outer surfaces and ball mill axis 5 than describedly giving, the angle of ore discharge sleeve 3,4 inwalls and ball mill axis 5 is large.The gap of the described edge of a wing 2 inner surfaces and ball mill main shaft 6 axle journal inwalls is greater than the thickness of the described seam end 301,401 to, ore discharge sleeve.
