Abstract
The utility model discloses a barrel of a ball grinder. The barrel comprises a barrel body, a lining plate and a lining plate fixing device, wherein the lining plate fixing device comprises a depression bar, a nut and a bolt; the depression bar is fixed at the T-shaped end of the bolt and embedded into the lining plate; the bolt passes through the lining plate and the barrel body and then is sleeved with a gland and screwed by the nut; a seal pad is sleeved on a rod of the bolt; an annular groove corresponding to the gland is formed in the barrel body; the depression bar is fixed at the T-shaped end of the bolt and embedded into the lining plate, so that the bolt is prevented from being punched; abrasion and loosing of the bolt are avoided; the service life of the barrel and the lining plate is prolonged. The seal pad is sleeved on the rod of the bolt, so that no clearance is formed among the bolt, the barrel and the lining plate. The annular groove corresponding to the gland is formed in the barrel body, so that the sealing effect between the gland and the barrel is better; external materials are prevented from entering.
Description
Technical field
The utility model relates to a kind of equipment that grinds, particularly a kind of ball mill barrel.
Background technology
Ball grinding machine lining board is bolted on cylindrical shell, but due to ball mill in when work, liner plate in cylindrical shell is received larger impact, bolt has been caused to certain wearing and tearing and loosening, make between liner plate and cylindrical shell loosening, mineral aggregate enters cylindrical shell, causes liner plate and cylindrical shell serious wear, has reduced the service life of liner plate and cylindrical shell.
The utility model content
For above-mentioned situation, the utility model purpose is to provide a kind of long service life, liner plate to be difficult for loosening ball mill barrel.
The technical solution of the utility model is a kind of ball mill barrel, comprise cylindrical shell body, liner plate and lining board fixing device, described lining board fixing device comprises press strip, nuts and bolt, the T-shaped end of bolt is fixed with press strip, press strip embeds liner plate, after bolt passed liner plate and cylindrical shell body, the cover upper press cover was also used nut screwing clamping, and on the bar of bolt, cover has sealing gasket, and the cylindrical shell body is provided with the cannelure corresponding with gland.
The beneficial effects of the utility model are: the T-shaped end of bolt is fixed with press strip and press strip embeds liner plate, and the protection bolt is not subjected to punching press, has avoided the wearing and tearing of bolt and has become flexible, and has extended the service life of cylindrical shell and liner plate; On the bar of bolt, cover has sealing gasket, can make between bolt and cylindrical shell body and liner plate very close to each other; The cylindrical shell body is provided with the cannelure corresponding with gland, can make between gland and cylindrical shell sealing effectiveness better, prevents entering of external substance.
