Product Introduction

Screening Type Double-toothed Roll CrusherThe classified double-toothed roll crusher is a new type of classified crusher developed by our company based on imported similar product technology. It is completely different from traditional roll crushers that crush materials through compression and breaking, but instead uses a combination of shearing and stretching forces to achieve material crushing. The classified double-toothed roll crusher is equipped with two horizontally installed and parallel toothed rollers in the crushing chamber. The surface of the toothed drum has broken teeth. The toothed rollers are rotated by the transmission device (single motor drive or dual motor drive), finally applying shearing and stretching forces to the materials, causing them to break. When a larger crushing ratio is required, adjustable crushing bars can be installed below the two rollers of the stepped double-toothed roll crusher. When the toothed rollers hold the material, the first stage of crushing occurs, and when the material passes through the double rollers, the second stage is generated. In the third stage of crushing, the crushing bars can cooperate with the roller teeth to perform tertiary crushing on the fragments produced in the first two stages.

Advantages of the Screening Type Double-toothed Roll Crusher

(1) The breakthrough in crushing theory of the screening double-toothed roll crusher makes it more compact and lighter than other crushing equipment with the same output, reducing investment costs.

(2) The screening double-toothed roll crusher is completely different from traditional double-toothed roll crushers. It uses tensile force and shear force to crush ores, thereby reducing powder content and achieving relatively uniform product particle size.

(3) The screening double-toothed roll crusher features large tooth profiles, and the design of tooth position and spacing ensures that particles smaller than the acceptable lump size can pass through the crushing section without being crushed, thus reducing crushing power consumption. This unique characteristic enables high processing capacity at low speed and low wear.

(4) When processing materials with high moisture content and thicker feed, sparse plates can be installed on both sides of the crushing roll to clean the teeth and prevent adhesion.

(5) Hydraulic couplings and hardened surface reducers are used for transmission. The hydraulic coupling ensures smooth transmission and provides overload protection; the hard tooth surface gear reducer offers high transmission efficiency, long service life, and compact structure.
