Four -roller crusher detail information 

     Four-roll crusher for crushing strength of less than 200Mpa, less than 30% of the humidity, hard and medium hard materials crushing operations. Such as coke, coal, ceramic raw materials, quartz stone, limestone, feldspar, water slag, gypsum, clay, salt, chemical raw materials and other solid materials, the machine has a special low maintenance, crushing ratio, reliable, Low noise and so on.

    Four roller crusher configuration four roller, according to the user needs crushing granularity, divided into two models:

    A, four-roll two broken models
    Four-roll two-crusher is a universal four-roll crusher. The four rollers are divided into surfacing roller surface or flat roller surface. The combination of the two sizes is suitable for feeding granularity less than 90mm and finished granularity 60 mesh. To 5 mm of crushing operations. Such as iron and steel production coke; coking plant production of coal; quartz industry production of quartz powder; iron ore industry production of iron powder; or similar to the above-mentioned crushing occasions.

    B, three-four-roller models
    Four roller three broken models is my own research and development, the market's unique patented product. Four roller surface is divided into surfacing roller surface or flat roller surface, in accordance with the user requirements of the size of the combination of choice for feed particle size of less than 90mm, finished particle size requirements of 100 to 5 mm ultra-fine crushing operations. Such as mining industry production of quartz powder, fine iron powder; ceramic industry broken long powder; thermal power plant manufacturing powder desulfurization; cement manufacturing powder, coal; building materials manufacturing gypsum powder; chemical industry broken various chemical raw materials; or similar Broken occasions.

2. four roller crusher  working principle

    Four-roll crusher is the use of four high-strength wear-resistant alloy roller, the relative rotation of the high extrusion pressure and shear to break the material. After the material enters the uppermost two-roll V-shaped crushing chamber, the material is squeezed and rubbed for the first time (rough break) by the squeezing force of the relative rotation of the upper and lower rolls, and then enters the middle two rolls of the relative rotation, The two rolls were subjected to secondary squeezing and pinching (fine breaking), and finally into the next two rolls, again using the next two rollers for the third squeeze, shear and grinding (superfine crushing) (only Applicable to the four-roll three-crusher type) broken into the required size sent by the conveyor equipment.
