JY4PG four-tooth roll crusher

The four-tooth roll crusher is suitable for medium and fine crushing operations with a feed particle size of less than 700mm and a finished product particle size requirement of 2-20mm. Applications include crushing coal for circulating fluidized bed boilers and conventional boilers in thermal power plants; crushing fertilizer raw materials in fertilizer plants; crushing waste glass tubes in the solar energy industry; or similar crushing applications.

Product Introduction

The four-tooth roll crusher is suitable for medium and fine crushing operations with a feed particle size of less than 700mm and a finished product particle size requirement of 2-20mm. Applications include crushing coal for circulating fluidized bed boilers and conventional boilers in thermal power plants; crushing fertilizer raw materials in fertilizer plants; crushing waste glass tubes in the solar energy industry; or similar crushing applications.

Working principle

The four-roller crusher utilizes four high-strength wear-resistant grinding rollers that rotate relative to each other to generate high squeezing and shearing forces for crushing materials. After entering the gap between the upper two rollers (V-shaped crushing chamber), the material is subjected to the squeezing and shearing action of the two rollers rotating relative to each other, undergoing initial squeezing, shearing (coarse crushing). Then, it enters the lower two rollers that rotate relative to each other, where it is further squeezed, sheared, and ground (fine crushing) into the desired particle size before being discharged by the conveying equipment.
