PRODUCT INTRODUCTION

Double -toothed roller crusher is also called classified tooth roller crusher. It is a new concept class crushing equipment developed by our new Gaotai Group with many years of industry experience and adopting advanced technology, its innovative tooth roller technology can ensure the high -efficiency crushing operation of the material, and has a significant advantage of handling dry materials, wet materials, mud and adhesion.

ADVANTAGES

High broken rate

The crushing teeth are cast with Babbitt grinding alloy, and the service life is 2-3 times that of high-strength steel and alloy steel commonly used in the industry; the dual-structure independent drive device is energy-saving and efficient.

Excellent shape

The shape of the stick surface is divided into coarse and fine tooth rollers, which can be adjusted according to the size of the material required for production; low speed, special tooth shape, less over-grinding and over-graining of materials, and the proportion of finished products in the 40-90mm section can reach 75%.

Cost-effective

The crushing tooth type, crushing tooth arrangement and walking structure are diversified, which can be optimized and selected for customers according to the working conditions, customized, high crushing efficiency, and easy maintenance.

Reasonable design

Special main shaft structure, crushing rod cleaning device, intelligent control system, easy to operate; the crushing chamber adopts the overall box structure, and the working environment is clean.

WORKING PRINCIPLE

Double Roll Crusher WORKING PRINCIPLE
After the two motors are deceived by the reducer through the reducer, the two parallel installed tooth rollers are rotated. When the material falls between the two rollers of the graded crusher, with spiral teeth or blade -shaped tooth plates, the material is sieved first, and particles smaller than the particle size of the discharge are directly passed without crushing,under the common action of vertical stress or shear force, large pieces of materials are split, cut, and stretched by the tooth roller tooth teeth.
