4pg Four Roller Crusher for Stone and Ore

Introduction:
Four roller crusher is suit for less than 30 % of the compressive strength of hard, hard material crushing operations, such as coke, coal, ceramic materials, quartz, limestone, feldspar, water, gypsum, clay, salt, chemicals and other solid materials, the characteristic of the machine is low maintenance costs, high crushing ratio, reliable performance, low dust, low noise.
Four roll crusher configuration of four grinding rollers, broken particle size according to user needs, is divided into two models: our broken grind two models and four broken grind three models.

A. four broken grind two models:
Four pieces grind two common models for the four mill crusher, milled surface is divided into four welding surface grinding according to size and select a combination of user requirements for a small feed size 90mm, required finished size of 60 mesh finely -5mm operations, such as iron and steel plant coke, coking plant explosive powder, quartz silica powder production industry, the production of iron ore industry, etc., or similar to the above broken occasions.

B. four broken grind three models:
Four grind three broken model is developed by our company, the market's unique patented product. Grinding surface is divided into four welding roller surface or flat roll surface, according to the granularity choose a combination of user requirements for feed size less than 90mm, finished 100 mesh size requirements -5mm ultra- crushing operation, such as the mining industry, the production of quartz powder, fine iron powder, feldspar powder ceramics industry production, power plant desulfurization powder manufacturing , cement manufacturing powder, coal, building materials, gypsum powder manufacturing plant, crushing all kinds of chemical raw materials, chemical industr etc. or similar to the above broken occasions.

Working principle
Four toothed roll crusher is the use of four high strength wear resistant broken roller relatively high extrusion pressure and shear force produced by the rotation to materials, broken two teeth on the material into the roll gap (V) crushing cavity.problems in the design, by two teeth roll relative rotation of extruding and shearing action, for the first time after JiGa, shear (thick), material again into the relative rotation under two roller, again by the two-roll JiGa gritting, shear, and the granularity of powder (break) in need by conveying equipment to send out again.
