Double tooth roller crusher is mainly used in coal, cement, silicate and other industrial sectors. The crushing mechanism is mainly splitting and grinding. It is suitable for coarse and medium crushing of brittle and soft ores. Coarse-toothed rollers can be used according to the characteristics and requirements of the crushed materials.
Applicable materials
Mainly used for crushing coke, also suitable for crushing raw coal and other materials of similar hardness or hardness in coal mines or coal preparation plants
The double-toothed roller crusher is named for its double rollers with teeth on them. It is mainly used for coke cutting in coking plants. It can also be used for coarse and medium crushing of low-hardness brittle materials in industrial sectors such as ore dressing, chemical cement, refractory materials, electricity, and building materials. Our company has quite mature technology in producing double-toothed roller crushers and double-roll crushers. They are the company’s best-selling crushing equipment. You are welcome to come and buy them.
Outstanding advantages
Compared with other types of crushers, this series offers a large crushing ratio and accommodates materials with any moisture content without sticking or clogging. It minimizes over-crushing, noise, vibration, and dust while consuming less energy and occupying a smaller footprint. Maintenance is simple and convenient.
The crusher includes a hydraulic automatic retreat device, which effectively prevents iron blocks from damaging the tooth rollers and stops wood blocks and flexible objects from interfering with normal operation. Additionally, it features an intelligent removal device that automatically clears adhered materials from the crusher cavity wall during working intervals.
The use of multiple protection devices and interlocking devices such as mechanical, electrical, and hydraulic effectively protects the motor, crusher, and the entire system
This product has become the preferred equipment for thermal power plants to replace imported crushing equipment with its advantages of high efficiency, energy saving, and environmental protection. It is suitable for crushing brittle materials with medium and low hardness, such as bituminous coal, anthracite, lignite, and coal gangue. It can also be used for sintered ore, coke slag, shale, and limestone, etc.
Working Principle of Double-Tooth Roller Crusher:
- Structural Composition: The machine mainly consists of rollers, roller support bearings, and clamping and adjustment devices. The two crushing rollers are fixed on rotating shafts, supported by bearings at both ends, and installed on the base.
- Bolts secure the active roller to the base frame, while the driven roller is equipped with a safety spring and a movable bearing. When adjusting the roller gap or when a metal object falls between the rollers, the driven roller can move horizontally, preventing damage to machine parts.
- Working Principle: The machine’s driving mechanism uses one or two motors, which drive the rollers through belt drives. The rollers rotate in opposite directions to crush materials. During operation, the material enters through the feed port, where the rollers roll and squeeze it, resulting in crushed material that is discharged from the bottom frame.
