The four-roller crusher is a new product based on the extension of the double-roller crusher and the double-toothed roller crusher.It combines the advantages of double roller crusher and toothed roller crusher. It can also be said to be a collection of these two equipment.It is suitable for finely crushing hard and medium-hard materials with compressive strength less than 300Mpa and humidity less than 30%.
Clay, salt, coal, coal gangue, coke, limestone, iron ore, quartz stone and sulfur ore
Cement, chemical industry, electric power, mining, metallurgy, building materials, refractory materials, coal mines.
After the material of the four-roller crusher enters the upper two-roller V-shaped crushing cavity, it will be squeezed and grinded by the relative rotation of the upper two rollers, and then use the extrusion force of the middle two rollers to enter the relatively rotating middle two rollers. After the pressure is subjected to secondary squeezing and fine crushing, it enters the next two rollers and is crushed into the required particle size and sent out by the conveying equipment.
