Abstract
The invention relates to a method for sealing installation gaps of liner plates at the end cap of a ball mill. The method is as follows: the disk-shaped end cap is connected with the shell of the ball mill through bolts, the sector liner plates are assembled together and fixed on a recessed surface of the disk-shaped end cap, and a quick-setting ash material is filled into spaces or gaps between all the assembled sector liner plates, between the sector liner plates and the recessed surface of the disk-shaped end cap and between the bolts and bolt holes; the ash material is prepared by blending atomic ash and an atom ash curing agent. According to the invention, the quick-setting ash material is filled into spaces or gaps formed by the end cap and the sector liner plates in advance so as to seal the spaces or gaps, thereby preventing ore pulp from entering into the spaces or gaps, avoiding wearing of the end cap, the fastening bolts, the bolt holes and transmission parts caused by leakage of the ore pulp and improving reliability and a serviceability rate of equipment.
Description
Technical field
The present invention relates to a kind of method of end cover of ball mill liner plate assemblage gap sealing.
Background technology
Ball mill is widely used in the ore dressing plant, cement plant in mine etc. need be to the enterprise of ore deposit rock dust breakdown mill, and the ball mill serviceability rate is decision enterprise production continuity, accomplishes one of key of production task with the rate of starting.The general volume of ball mill is big, equipment heavy, the maintenance difficulty, and recondition expense is also bigger; Because the general life cycle of end cover of ball mill liner plate is 5-6 month,, be fastened on fan-shaped grid liner plate splicing through bolt the concave surface of ball mill disc end cap for being convenient for changing.But; Between each fan-shaped grid liner plate of splicing, between the concave surface of fan-shaped grid liner plate and ball mill disc end cap and all have gap or space between bolt and the bolt hole, ore pulp gets into grinding mill barrel from feeding mouth, along with grinding machine rotates; Behind ore grinding Jie steel ball grinding, flow towards discharging opening; Ore pulp can be from above-mentioned gap or the space get between the concave surface of fan-shaped grid liner plate and ball mill disc end cap, along with ball mill running (rotating speed is generally 25-35 rev/min), ore pulp and end cap, fastening bolt, bolt hole produce wearing and tearing and cause the ore pulp leakage; Spill ore pulp and not only influence the equipment highly civilized health; Be more serious be ore pulp that gets into end cap and the ore pulp that spills even get into parts such as travelling gear, accelerated the drive disk assembly wearing and tearing, reduce service life; Strengthen the maintenance maintenance workload, influence production efficiency and increase the enterprise production cost.
Summary of the invention
The technical problem that the present invention will solve provides a kind of method of end cover of ball mill liner plate assemblage gap sealing
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of method of end cover of ball mill liner plate assemblage gap sealing; Comprise the concave surface that is fastened on fan-shaped liner plate splicing with the bolted disc end cap of ball mill barrel and through bolt the disc end cap; Adopt between each fan-shaped liner plate of rapid solidification ash material filling splicing, between the concave surface of fan-shaped liner plate and disc end cap and gap or space between bolt and the bolt hole; The filling of rapid solidification ash material seals said gap or space, prevents that ore pulp from leaking.Said rapid solidification ash material is formed by atom ash and the allotment of atom ash curing agent.
The invention has the beneficial effects as follows: use rapid solidification ash material to dispatch from the factory preceding or enterprise during in maintenance at grinding machine; End cap and fan-shaped liner plate are formed gap or space filling in advance sealing; Play and stop ore pulp to get into gap or space; Avoid the ore pulp leakage and cause wearing and tearing end cap, fastening bolt, bolt hole, drive disk assembly; Play protective effect in advance, for keep the safety in production, carry out production strictly in line with rules and regulations, improve equipment dependability, serviceability rate has been created condition, thereby promote the production of enterprise, the raising of economic benefit.

Fig. 1 is a structural representation of the present invention.
The specific embodiment
Embodiment 1As shown in Figure 1: a kind of method of end cover of ball mill liner plate assemblage gap sealing comprises the concave surface that is fastened on fan-shaped liner plate 3 splicings with ball mill barrel 1 bolted disc end cap 2 and through bolt disc end cap 2; Adopt between each fan-shaped liner plate 3 of rapid solidification ash material 4 fillings splicing, between the concave surface of fan-shaped liner plate 3 and disc end cap and gap or space between bolt and the bolt hole, 4 fillings of rapid solidification ash material seal said gap or space, prevent the ore pulp leakage; Ore pulp can only flow to grout outlet 5 through the grid of fan-shaped grid liner plate from cylindrical shell 1.
Said rapid solidification ash material 4 is formed by atom ash and the allotment of atom ash curing agent.
Claims (2)
1. the method for end cover of ball mill liner plate assemblage gap sealing; Comprise the concave surface that is fastened on fan-shaped liner plate (3) splicing with the bolted disc end cap of ball mill barrel (1) (2) and through bolt disc end cap (2); It is characterized in that: adopt between each fan-shaped liner plate (3) of rapid solidification ash material (4) filling splicing, between the concave surface of fan-shaped liner plate (3) and disc end cap and gap or space between bolt and the bolt hole; (4) filling of rapid solidification ash material seals said gap or space, prevents that ore pulp from leaking.
2. according to the method for the said a kind of end cover of ball mill liner plate assemblage gap sealing of claim 1, it is characterized in that: said rapid solidification ash material (4) is formed by atom ash and the allotment of atom ash curing agent.
