Abstract

The invention discloses a crushing equipment for silicon waste. The crushing equipment for the silicon waste comprises a shell body, wherein a charge hopper is formed in the upper part of the shell body; a discharge pipe is arranged at the bottom of the shell body; a roller is arranged in the shell body; a lining sleeves outside the roller; the lining is connected with the roller through bolts; crushing teeth are arranged on the lining; tooth-shaped nut sleeves sleeve the bolts and nuts matched with the bolts; each tooth-shaped nut sleeve comprises a tooth-shaped cover; an accommodating cavityis formed in the bottom of each tooth-shaped cover; the accommodating cavities are used for accommodating the bolts and the nuts which are located on the surface of the lining; a clamping ring is arranged in each accommodating cavity; the inner wall of each clamping ring extrudes the outer surface of the corresponding bolt; the outer wall of each clamping ring extrudes the wall surface of the corresponding accommodating cavity; a groove is formed in the inner wall of the shell body; a moving plate is arranged in the groove; and a spring is arranged between the moving plate and the groove. Thecrushing equipment for the silicon waste is capable of playing a good role of double protection on the nuts and a part of the bolts which are located on the outer wall of the lining.

Description

technical field [0001] The invention relates to the field of pretreatment of silicon slag recovery, in particular to crushing equipment for silicon waste. Background technique [0002] In the industrial silicon recovery process, it is necessary to break the silicon slag into required size silicon slag for subsequent separation and smelting process. [0003] The main equipment used in the silicon slag crushing process includes cone crusher and roller crusher. Among them, the roller crusher is divided into single-roll crusher, double-roll crusher and multi-roll crusher according to the number of rollers, and divided into smooth crusher and tooth surface crusher according to the shape of the roller surface. [0004] The single-roll crusher is equipped with a roller, which is covered with a bush with crushing teeth. During operation, the roller rotates, and the silicon material between the roller and the inner wall of the shell is crushed by the extrusion of the roller and the...
