Roller type crusher with front discharging device

Abstract

The invention relates to a roller type crusher, in particular to a roller type crusher with a front discharging device. The roller type crusher with the front discharging device is composed of a cooler, a screening plate, a roller type crusher body, a discharging hopper and a bolt pair. According to the technical scheme, the screening plate is additionally arranged, so that granular clinker, powdery clinker and small-sized clinker, which do not need to be crushed, in mixed clinker are screened out in advance before the mixed clinker enters the crusher body, and the working efficiency of the roller type crusher is greatly improved. Meanwhile, the wear rate of roller sleeves in the roller type crusher is decreased, the service life of the roller sleeves is prolonged, the production cost is reduced, and resources are saved.

Description

technical field [0001] The invention relates to a roller crusher, in particular to a roller crusher with a front discharge device. Background technique [0002] At present, the roller crusher used by the cooler in the cement plant, whether it is a domestic or imported product, the cement clinker mixture must be crushed by the roller crusher before it can be transported out of the cooler for further processing. This type of roller crusher has a simple structure, but it cannot separate small block, granular, and powdery clinker when in use (according to the requirements of cement technology, as long as the clinker is below a certain size b, it can be crushed without crushing. can enter the next process), the granular and powdery clinker that does not need to be crushed will also enter the crusher for re-crushing, which greatly reduces the working efficiency of the roller crusher, and at the same time increases the wear of the roller sleeve, making the roller sleeve reduced se...

This type of roller crusher has a simple structure, but it cannot separate small block, granular, and powdery clinker when in use (according to the requirements of cement technology, as long as the clinker is below a certain size b, it can be crushed without crushing. can enter the next process), the granular and powdery clinker that does not need to be crushed will also enter the crusher for re-crushing, which greatly reduces the working efficiency of the roller crusher, and at the same time increases the wear of the roller sleeve, making the roller sleeve reduced service life

The roller sleeve is an important part of the roller crusher, and it is also a vulnerable part. Its material requirements are high, the cost is high, and the replacement process is complicated. In addition, the entire production line needs to be stopped during the replacement, which takes too long and delays production; therefore, Reducing the wear of the roller sleeve and improving its service life has always been the research direction of the roller crusher.
