Embodiment Construction

[0016] As shown in the figure, the specific implementation method is as follows:

[0017] A shell device for a dry-process ball mill, comprising a shell 1 and a detachable wear-resistant layer 2 attached to the inner wall of the shell 1. The detachable wear-resistant layer 2 is composed of several wear-resistant units spliced ​​with each other. The grinding unit includes a metal base 4 and a ceramic wear-resistant block 3. The bottom surface 403 of the metal base 4 has an arc surface structure and the arc surface matches the shape of the inner wall of the housing 1 so that the two can be closely attached. The top surface of the metal base 4 Four grooves 402 are opened on the top, and a ceramic wear-resistant block 3 is arranged in each groove 402, and one end of the ceramic wear-resistant block 3 is exposed outside the groove 402, and one end of the ceramic wear-resistant block 3 is exposed outside the groove 402 It is a corrugated curved surface to provide a ball grinding sur...

Abstract

The invention discloses a shell device for a dry ball mill. The shell device comprises a shell, and a detachable wear resisting layer bonded on the inner wall of the shell; the detachable wear resisting layer is assembled by multiple wear resisting units; the wear resisting units comprise metal bases and ceramic wear resisting blocks; grooves are formed in the top surfaces of the metal bases; theceramic wear resisting blocks are arranged in the grooves; one ends of the ceramic wear resisting blocks are exposed out of the grooves; and the metal bases are provided with mounting holes for fixingthe metal bases on the inner wall of the shell through connecting pieces. The shell device adopts a double-layer structure, wherein the inner side adopts the detachable wear resisting layer; on the one hand, the wear resistance is improved through use of wear resisting materials; and on the other hand, replacement is convenient and the overall service life is prolonged through the detachable structure; the wear resisting units adopt a form of combining the metal bases with ceramic; and the ceramic wear resisting blocks are adopted on wear resisting surfaces, so that the wear resistance can beimproved, meanwhile, the overall weight is reduced, and carrying and replacement are convenient.

Description

technical field [0001] The invention relates to a ball mill device, in particular to a shell device for a dry ball mill. Background technique [0002] Dry ball mill is a kind of equipment that grinds materials in the form of dry method. It is the key equipment for crushing materials after they are crushed. It consists of two parts: a ball mill tank and a recovery cover. The material is spirally and evenly entered into the first chamber of the mill through the feeding hollow shaft by the feeding device. There is a liner in the chamber and steel balls of different specifications are installed inside. The rotation of the cylinder generates centrifugal force to bring the steel balls to a certain height and then fall down. Bumping and grinding are produced. After the material reaches coarse grinding in the first warehouse, it enters the second warehouse through a single-layer partition board. The second warehouse is lined with a flat liner and steel balls inside, and the material...
