Product Introduction

　　Four-tooth roll crusher is suitable for compressive strength less than 200Mpa, humidity less than 30% of the medium hardness and soft materials, and requires the crushing size of powder less, more granular fine and medium crushing operations. Such as coal, coke, fertilizer raw materials, petroleum coke, glass tube, chemical raw materials and other solid materials, the machine has the use of low maintenance costs, large crushing ratio, reliable performance, less dust, low noise and other characteristics.

　　Working Principle

　　The four-tooth roller crusher uses four high-strength wear-resistant rollers, the upper and lower rollers can be selected according to the needs of the toothed rollers or light rollers, the relative rotation of the high squeeze force and shear force generated by the crushed material. After the material enters the gap between the upper two rolls (V-shaped crushing chamber), it will be squeezed and sheared by the relative rotation of the two rolls, which will squeeze and shear the material (coarse crushing), and then it will enter into the relative rotation of the lower two rolls, and then be squeezed, sheared, and ground by the lower two rolls (fine crushing) into the required granularity to be sent out by the conveying equipment.

　　Product features

　　1. high efficiency, safety, energy saving and environmental protection and large crushing ratio;

　　2. no requirement for the moisture of the crushed material, non-stick and non-blocking;

　　3. uniform fabric device and fine screening device into one design, completely eliminating the phenomenon of over-crushing;

　　4. coarse crushing and fine crushing close combination of design, so there is no need for the entrance to install dust-absorbing devices;

　　5. less noise, less vibration, less dust, low power consumption;

　　6. adjustable discharge size;

　　7. small footprint, simple maintenance;

　　8. the use of hydraulic or spring automatic retreat device and debris removal device, can effectively prevent the non-ferrous alloy lumps, hard stones on the rollers of the damage and wood and flexible objects on the rollers of the normal work of the hazards. Products
