Four Roll Crusher

The four-roll crusher is a new product based on the extension of the double-roll crusher and the double-toothed roller crusher. It contains the advantages of the two types of equipment, the double-roll crusher and the 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%.
Working principle：
After the material of the four-roll 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 enter the relatively rotating middle two rollers, using the squeezing force of the middle two rollers. After the pressure is subjected to secondary squeezing and fine crushing, it enters the next two rolls and is crushed into the required particle size and sent out by the conveying equipment.
