Four Roller Crusher Stone Broken Mining Machine Grinding Machine
1. Introduction
Four roll crusher is suitable for crushing solid materials that compression strength less than 300Mpa, moisture less than 30%, such as coke, coal, ceramic materials, ores, slag, gypsum, clay, salt, chemicals and other solid materials. Features: reliable performance, low maintenance, high crushing ratio, low dust, low noise.
The four roll crusher can be made up with: four welding roller or four flat roll , two flat and two welding rollers. According to the granularity and user's requirements, we can choose the proper combination. It is a good choice for feed size less than 90mm, finished size 0.2-10mm technical requirements. It can be used in many fields such as iron and steel plant crushing coke, coking plant crushing coal, quartz industry crushing quartz stone, iron ore in crushing industry, or at similar crushing occasions.
According to customer requirement, the driving mode is divided into triangular belt and shaft coupling. The driving power can be made by electric motor or diesel engine.
2. Working Principle
Four roll crusher is fixed with four high-strength wear-resistant alloy grinding rollers. Their relative rotation makes high extrusion pressure and shear force for crushing the material. Firstly, the material is entered into the space between the top two rollers. Here, it is extruded, pressed and sheared (thick broken) because of the relative rotation of the top two rollers. Then, it is secondly extruded and gnawingly milled (fine crushing) by the middle two rollers which are relatively rotating. Finally, under the extrusion, cut and mill of the next two rollers, the material becomes the required size and sent by the transport equipment.
