Roll crusher

Abstract

The invention discloses a roll crusher, which comprises a frame, a drive motor, a transmission belt, a pair of drive roll and a driven roll grinding and rotating in an opposite direction and a transmission gear pair, wherein the drive roll is connected with the drive motor through the transmission belt; the driven roll is connected with the drive roll through the transmission gear pair and is driven by the drive roll to rotate; the roll crusher further comprises a floating structure; the driven roll is connected with a floating structure; and an acting force generated by blanking between the drive roll and the driven roll drives the floating structure to move, so that the driven roll is driven to move, and the breaking clearance between the drive roll and the driven roll to is adjusted automatically. The roll crusher has the advantages that by virtue of hardness of a material and material feeding amount, the driven roll is designed to be a floating type, so that the clearance between breaker rolls can be adjusted automatically; the structure is simple; the material is not powdered or flattened due to large material feeding amount, or is not bonded on the breaker roll; and the roll crusher is suitable for crushing a plurality of raw materials.

Description

technical field [0001] The invention relates to a roller crusher, in particular to a roller crusher which can automatically adjust the crushing gap. Background technique [0002] Ordinary crushers can only crush hard granular materials without grease. When encountering materials with high oil content, such as Schisandra chinensis and other raw materials in the production process of traditional Chinese medicine, due to the viscosity of the materials, the materials will be stuck in the crushing process. On the crushing roller, the crushing effect cannot be achieved, and the cleaning of the crushing roller is also very difficult. Ordinary crushers also need to feed at a constant speed. When the amount of material fed is large, the crushed material will be crushed and crushed due to the fixed gap between the driving roller and the driven roller. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the present invention is ...

Problems solved by technology

[0002] Ordinary crushers can only crush hard granular materials without grease. When encountering materials with high oil content, such as Schisandra chinensis and other raw materials in the production process of traditional Chinese medicine, due to the viscosity of the materials, the materials will be stuck in the crushing process. On the crushing roller, the crushing effect cannot be achieved, and the cleaning of the crushing roller is also very difficult

Ordinary crushers also need to feed at a constant speed. When the amount of material fed is large, because the gap between the driving roller and the driven roller is fixed, the crushed material will cause crushing and flattening damage.
