Abstract

The invention discloses a single-roller crusher with a tooth-shaped nut cover, which comprises a shell, a feeding hopper is arranged on the upper part of the shell, a discharge pipe is arranged on the bottom of the shell, a roller is arranged inside the shell, and the roller is covered outside. A bushing is provided, and the bushing and the roller are connected by bolts. The bushing is provided with crushing teeth, and the bolts and nuts matched with the bolts are covered with toothed nut sleeves. The present invention can better protect the nuts and some bolts located on the outer wall of the bushing. The first protection function is that the crushing teeth isolate the silicon material from the bolts and nuts, so that the silicon material is The material will not cause any wear and extrusion to the bolts and nuts, and the nuts can be removed from the bolts normally when the bushing is disassembled; the second protective effect is that the fine silicon slag and silicon powder will not fall during the crushing process In the gap between the bolt and the screw hole, the bolt is evenly stressed, the bushing is firmly installed, and the bolt can be taken out of the nut normally.

Description

technical field [0001] The invention relates to the field of pretreatment for silicon slag recovery, in particular to a single-roller crusher with a toothed nut sleeve. Background technique [0002] In the industrial silicon recovery process, the silicon slag needs to be broken into the required size for the 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-roller crusher, double-roller crusher and multi-roller crusher according to the number of rollers, and is divided into smooth crusher and tooth surface crusher according to the shape of the surface of the roller. [0004] The single-roller crusher is provided with a roller, and the roller is covered with a bushing with crushing teeth. The roller rotates during operation, and the silicon material between the roller and the inner wall of the shell is crushed by the...
