Pair (Double) Roll Crusher product description
Pair (double) roll crusher is suitable for secondary crushing and fine crushing of solid materials with compressive strength less than 250Mpa and water content less than 35%, such as crushing iron ore, quartz stone, potassium (sodium) feldspar, limestone, river pebbles , silicon metal, barite, basalt, granite, steel slag, cement clinker, construction waste (concrete), shale, quicklime, coal, coke, clay, bentonite, chemical raw materials, etc. It can be widely used in mining, thermal power, cement ceramics, metallurgy, chemical industry, building materials and other industries. It has the characteristics of low maintenance cost, low moisture requirement, reliable performance, low power consumption, less dust, and low noise.
The (double) roller crusher is equipped with two crushing rollers. According to the granularity required by the user, the roller surface is divided into two types: flat roller surface and surfacing roller surface. Fine crushing operations of 1-10mm are required. The surfacing roller surface machine is suitable for medium and fine crushing operations with a feed particle size of less than 60mm and a finished product particle size of 5-30mm.
If the compressive strength of the material exceeds 250Mpa, it is recommended to choose an energy-saving roller press (grinding) machine. According to user requirements, it is divided into V-belt and coupling transmission (hard link). This equipment can be used in mines without electricity. Change to diesel engine or gasoline engine as power.
Pair (Double) Roll Crusher working principle
The pair (double) roll crusher uses two high-strength wear-resistant alloy crushing rollers to crush the material by the high extrusion force generated by the relative rotation. Under the action of extrusion force and shear force, under the extrusion, shearing and grinding, the material is broken into the required particle size and discharged from the discharge port.
