Description

Double Roller Crusher Introduction: 
Double roller crusher is configured with two crushing rollers , according to the granularity user needs, the roll surface is divided into two forms: flat surface and welding roller surface, heavier models can be selected if the compressive strength of the material is more than 200Mpa .
Flat roller surface models is suitable for the following technical requirements: feed size less than 80mm, finished size 0.5-10mm . Such as the use of pebbles , construction waste making sand ; mining crushing iron ore, quartz stone ; ceramic industry break raw materials ; metallurgical industry crushing coke , quicklime ; coking plant finely pulverized etc, or at similar crushing occasions.
Welding roller surface models suitable for feed size less than 150mm, finished size 3 – 30mm in crushing operations. It can be used in the pre- crushing of cement clinker in cement industry , limestone and composites; CWS industry pre- crushing coal; iron ore industry pre-crushing slag , iron ore, silicon ore; brick factories crushing all kinds of ore to make unburned brick ; power plant crushing coal; or at similar crushing occasions .

Working Principle:
Double roller crusher has two high-strength wear-resistant alloy crushing rollers. The two rollers turn relative together to generate high extrusion pressure to break materials, The material enter into the space between the two rolls, suffered both extrusion and shear force. In the crusher rolling, cutting and grinding, it is crushed into the required size and then sent by the transport equipment.
