Description

Technical Field

[0001] The invention relates to the technical field of crushers, in particular to a hydraulic compound roller crusher. Background Art

[0002] Hydraulic roller crusher is a new type of roller crusher developed by absorbing advanced technologies at home and abroad. Its unique structural performance fills the domestic gap and becomes the preferred equipment in the current field of cement and other material crushing. It can be used in the industries of mineral processing, chemical industry, refractory materials, stone, building materials, etc. to crush various high and medium hardness materials. It uses the extrusion, grinding and shearing force generated by two sets of independently driven rollers rotating in opposite directions to crush the materials. After the material enters the crushing chamber of the machine, it is forced to pass between the two rollers by the "biting" force of the roller surface. At the same time, it is crushed by the combined action of the extrusion, grinding and shearing force of the roller surface, and begins to break. The broken small particles are thrown downward along the tangential direction of the roller rotation through the gap between the two rollers. Generally speaking, the feed particle size is related to the size of the crushing roller diameter; the larger the roller diameter and the larger the roller gap, the larger the feed particle size allowed, and vice versa. When the crushing ratio is 5-10, the crushing effect is better.

[0003] At present, material crushing is an indispensable process in the production of products in many industries such as mining, building materials, chemicals, and metallurgy.

When crushing, the size and hardness of materials are different, which will lead to poor crushing effect due to the size of the materials.
