Introduction

Four rollers three-stage crusher is suitable for the solid materials that compression strength less than 240Mpa, water content less than 30%to proceed superfine crushing.Solid materials such as coke,coal,ceramic raw

materials,ore,water slag,gypsum,clay,salt,chemical raw materials,etc.,have the characteristics of low maintenance cost,large crushing ratio,reliable performance,less dust and low noise.

Four rollers three-stage crusher is the patented product (ZL 201020529725.7)which is self-developed and

manufactured by our company.The four roll faces are divided into a surfacing roll surface,a flat roll surface or a stud alloy roll surface.The combination can be selected according to the user’s required particle size,and is

suitable for superfine crushing operations with a feed size of less than 60 mm and a finished product size of

0.1-5 mm.Such as crushed quartz stone,iron ore in the mining industry,broken feldspar in the ceramic industry: broken limestone in thermal power plants;broken water slag in cement plants;broken gypsum in building

materials factory;broken chemical raw materials in chemical industry;or similar crushing occasions.

Working Principle

The four-roller three-stage crusher uses four high-strength wear-resistant alloy crushing rolls to crush the

material with high compression and shear forces generated by relative rotation.After the material enters the top two rolls of the V-shaped crushing chamber,it is subjected to the pressing force of the relative rotation of the     upper two rolls.After the first rolling and biting of the material (coarse crushing),and then entering the relatively  rotating middle two rolls V-shaped crushing After the cavity is subjected to secondary extrusion and biting (fine  crushing),finally enters the next two rolls of V-shaped crushing chamber for the third rolling,shearing and biting (superfine crushing)and then crushed into the required particle size to be discharged from outlet.
