Combined crushing teeth of single tooth roller crusher

Abstract

The invention relates to combined crushing tooth of a single teeth-roller crusher, comprising a single tooth roller main shaft and combined crash teeth which are connected with the single tooth roller main shaft. The invention is characterized in that the combined crash teeth are composed of a left tooth body, a right tooth body and connecting pieces, wherein, the right tooth body is connected with the single tooth roller main shaft by welding; the root part of the right tooth body is provided with a convex limited block; one end of the upper part of the left tooth body has a shape of hammer head and the other end is designed to be with a plush copper shape; the shape of the lower part of the left tooth body matches with the shape of the convex limited block which is arranged on the main shaft; the lower part of the right tooth body is connected with the main shaft by welding; the upper part of the right tooth body is designed to be a groove which matches with the plush copper shape of the upper part of the left tooth body; after assembling, the left tooth body and the right tooth body are fixedly connected through screws and nuts connecting pieces. The invention has the advantages of simple structure, reliable performance, convenient replacement, and the invention can lower investment cost and maintenance expenses of devices and improve working productivity.

Description

Combined crushing tooth assembly for single tooth roller crusher technical field The invention relates to the technical field of single-toothed-roll crushers, in particular to a combined crushing tooth assembly of a single-toothed-roll crusher. Background technique The single-toothed roller crusher is installed at the tail of the sintering machine and is used to crush the large sintered ore unloaded from the sintering trolley after sintering. The crushing tooth roller of the single-toothed roller crusher is its main crushing device. The crushing tooth roller is composed of the tooth roller main shaft, crushing teeth, bearings and other components. Among them, the main crushing task and the most severely worn part are its crushing teeth. The crushing teeth are evenly installed on the main shaft of the toothed rollers in the arrangement of several rows, the closer to the center of the toothed rollers, the more serious the wear of the crushing teeth, and the lighter the wear ...
