Double Roll Crusher is short for roll crusher or roll crusher. The roll crusher has simple structure and few over crushing phenomena. The tooth shape, size and arrangement on the roll surface can be changed with the material properties, and it can be used for .
A rotating eccentric shaft, axially guided by two sets of roller bearings mounted in the crusher housing, generates an oscillating movement in the freely rotatable, horizontally arranged crusher roll. Consequently, the crushing gap between the crusher roll and the jaw in the crusher housing changes continuously, which means the feed material is ...
Feature. 1. Used for almost any material and for crushing up to mm. 2. More economical because of its higher production capacity and lower power requirement. 3. Segmented roll designs available in a wide selection of tooth configurations and abrasionresistant materials for rugged performance and long life. 4.
The HÄNDLE roller crusher series. Roller crushers render cloddy raw materials meterable and prepare them for effective further processing in downstream equipment. Size reduction is achieved by appliion of pressure and shear forces between two slowly rotating rollers equipped with onepiece toothed disks or individually replaceable knives.
Roller crusher is suitable for coarse and intermediate crushing of brittle and massive materials in industries such as cement, chemical industry, electric power, mining, metallurgy, building materials, refractory materials, coal mines, etc. The granularity is adjustable, which can crush the material with vertical compression strength ≤160MPa.
