Description

Circular groove promotes the ball grinding machine lining board device of inlaying

The utility model relates to the ball mill technical field, and specifically a kind of circular groove promotes the ball grinding machine lining board device of inlaying.

In industry such as cement mine, electric power, chemical metallurgy, adopted at large as the ball mill of pulverizing milling apparatus.With potassium steel is traditional liner plate design of typical material, because the deficiency that exists on its structure, to brittle metal high-abrasive material liner plate was lost efficacy, so can not satisfy the development of high-abrasive material.

The purpose of this utility model is to provide the almost no requirement (NR) of a kind of toughness value to material, can give full play to the wearability of material, need not maintenance, and reliable and stable circular groove promotes the ball grinding machine lining board device of inlaying.

The technical solution of the utility model is: at the characteristics of brittle metal high-abrasive material liner plate inefficacy, the structure and the performance of tens of kinds of ball grinding machine lining boards compared in analysis, and, the viewpoint of " stress reinforced " and " the whole reinforcement " is proposed at of the destruction of impact endurance test shock ripple to liner plate.Design " circular groove promotes the liner plate of inlaying " in view of the above, its structure is mainly partly to be made up of circular groove liner plate and riveting plate two, liner plate and liner plate be connected to the formula of inlaying, one storehouse liner plate is plain edition (1) and Type B, two storehouse liner plates are plain edition (4) and A type, contact jaw has a projection partly (E) between the liner plate of common (1) liner plate and Type B, A type, and liner plate is the circular groove slot type, and the circular groove groove of a storehouse riveting plate is worked energetically the circular groove groove of two storehouse riveting plates.

In the running of ball mill, part abrading-ball is ceaselessly taken to certain altitude by cylindrical shell, " hammer " is to liner plate, this constantly " hammering " makes the riveting plate continue plastic deformation in the middle of adjacent two boards, increase the contact area with adjacent plate body, the two blocks of adjacent liner plates of riveting tightly, and apply prestressing force to two blocks of adjacent liner plates, with the stable integral structure of the common formation of the cylindrical shell that causes whole liner plates and grinding machine, i.e. " self-locking ".It is whole wear-resistant that self-locking becomes the whole liner plates on the cylindrical shell, each piece liner plate in the wearing course has all increased intensity own because of prestressing force and the whole effect of strengthening that rivet body itself produces, the very difficult fracture, both made certain piece plate body phenomenon of rupture occur, because of the riveting plate constantly carries out self-locking action and the whole effect of strengthening, liner plate both can not come off, and also can not reduce installation strength, did not influence the operate as normal of whole wearing course at all.

The utlity model has following characteristics: 1) structure because the employing combination is inlay, allow the metal material of high rigidity, low toughness class to obtain maximum heat place hardness, liner plate is difficult to the appearance fracture through prestressing force reinforcement and whole the reinforcement, has both made fracture also need not maintenance; 2) help applying of high-quality high-abrasive materials such as rich chromium cast iron, can save various alloying elements, reduce production costs; 3) ball mill barrel removes most bolts hole, has improved intensity, saves the liner spare part expense; 4) adopt high chrome lining to grind different material and high manganese steel lining plate contrast, it is nearly 20% that output improves, energy consumption reduction about 20%, can prolong 3-6 service life doubly, a large amount of minimizing maintenance man-hourses and expense, and alleviated working strength of workers, have remarkable social benefit and economic benefit; 5) reduce fault, improve production efficiency of equipment, and can prevent the material contaminated environment that leaks.

Below in conjunction with accompanying drawing the utility model is further described.

Among the figure, the common liner plate in 1-one storehouse, 2-B type liner plate, 3-A type liner plate, the common liner plate in 4-two storehouses, 5-one storehouse riveting plate, 6-two storehouse riveting plates, 7-grinds door lining, and 8-grinds door lining, 9-mill door riveting plate.

As shown in the figure, the utility model mainly partly is made up of for 5,6 liang circular

groove liner plate

1,2,3,4 and riveting plate, liner plate and liner plate be connected to the formula of inlaying.One storehouse liner plate is plain edition 1 and Type B, two storehouse liner plates be logical type 4 and A type, contact jaw has partly E of a projection between the liner plate of liner plate 1 and Type B, A type, and liner plate is the circular groove slot type, and the big nose of a storehouse liner plate contacts two storehouse liner plates, and to be protruding end contact with nose not with little nose.The circular groove groove of one storehouse riveting plate is worked energetically the circular groove groove of two storehouse riveting plates, be used for fixing the liner plate termination, it is arranged as: the riveting plate that does not have on the mill door inner periphery is the circumference symmetric arrangement, and the riveting plate is arranged as two blocks of riveting plates 9 of mill door on mill door 7,3 inner peripherys, with riveting plate of mill door symmetric arrangement, riveting plate bolting.During installation, utilize the geometry of liner plate itself and ball mill barrel to inlay and form.Installation cylindrical shell two ends begin earlier, and dress if need the grinding machine of partition panel, is installed partition panel to the door direction earlier, can adorn to door from the partition panel both sides simultaneously then.Mill door fixed head is installed earlier, and every circle liner plate is fixed by two fixed heads, and bolted is put to cylindrical shell constant radius plate place.Once can install simultaneously two, three circles radially or axially the riveting plate also all be placed directly on the corresponding end-faces of liner plate, the diameter laboratory mill can not considered axial riveting plate.The riveting plate adopts different thickness, because press the liner plate that designing requirement is produced, can not be in full accord after the combination with the interior girth of ball mill barrel, and therefore utilize riveting plate adjusting gap.

After driving to produce, because the interaction of abrading-ball, riveting plate, cylindrical shell, prestressing force constantly increases, liner plate has improved constantly self intensity, and and the ball mill barrel formation " community " of combining closely, can be in optimum Working for a long time, the resistivity of its impact power and impact shock ripple is imponderable near the mechanicalness the subject of knowledge and the object of knowledge of material.
