Double Roller Crusher Introduction:
Double roller crusher, a kind of mining machinery, is also called counter roller crusher. Mainly used to crush ore. This machine has the advantages of small size, large crushing ratio (5-8), low noise, simple structure, convenient maintenance, uniform particle size of crushed materials, low over-crushing rate, convenient maintenance, sensitive overload protection, safety and reliability. It is more suitable for the crushing of raw coal (including gangue) in large coal mines or coal preparation plants. The tooth roller crusher has a large crushing capacity, and the motor and the reducer are connected by a limit-type hydraulic coupling to prevent power overload and sensor overload protection, which is safe and reliable. The gear roller spacing is adjusted hydraulically, and the gear roller bearings are centrally lubricated. Optimal design of tooth shape, selective crushing of tensile and shear forces, high efficiency and low consumption, and even granulation. Double Roller Crusher Application Field:
It is suitable for coal, metallurgy, mining, chemical industry, building materials and other industries.

Double Roller Crusher Suitable Material:
Double roller crusher is suitable for medium and fine crushing of solid materials with compressive strength less than 250MPA and moisture less than 35%, such as crushing iron ore, quartz stone, potassium (sodium) feldspar, limestone, river pebble, metal Silicon, barite, basalt, granite, steel slag, cement clinker, construction waste (concrete), shale, quicklime, coal, coke, clay, bentonite, chemical raw materials, etc. It can be widely used in mining, thermoelectricity, cement ceramics, metallurgy, chemical industry, building materials and other industries. It has the characteristics of low maintenance cost, low moisture requirements, reliable performance, low power consumption, less dust and low noise.

Performance Characteristics Of Double Roller Crusher: The double roller crusher is equipped with two crushing rollers.It is composed of motor, bracket, fixed roller, movable roller and safety spring. The roller surface is mostly smooth, and the bearing of the movable roller can be moved along the frame, and it is pressed against the strong safety spring. When the particularly hard object falls in, the bearing can be removed and the object can be spit out. Before normal operation, the gap between the two rollers should be adjusted with shims to ensure the crushing ratio. Suitable for medium broken viscous stone According to the granularity required by the user, the roller surface is divided into flat roller surface and surfacing roller surface. The flat roller surface model is suitable for feeding with a particle size of less than 80mm. 1-10mm fine crushing operation, surfacing stick noodle machine is suitable for medium and fine crushing operation where the feed particle size is less than 150mm and the finished product particle size requires 5-30mm.

Advantages :
1. Equipped with PDG-II roller crusher in the grinding system, the production capacity of the grinding equipment can be fully exerted, generally the output can be increased by 30%-40%, and the total energy consumption can be reduced by 20%-30%. 2. Compact structure, light weight and small volume, for the grinding system with the same production capacity requirements, equipped with PDG-II roll crusher can significantly save investment. 3. Simple structure, small space occupation, convenient operation and maintenance. 4. The dustproof board is installed inside, which has good sealing performance, avoiding the splashing of small materials after crushing, less dust, low working noise, and greater improvement in working environment. 5. The optimized design of the abrasive roller body, the machine does not need to replace the roller body of the grinding machine for life, and the old type roller pair machine needs to be dismantled for overhaul and replaced the roller body within one year. 6. The replaceable wear-resistant lining board is installed on the grinding roller of the roller crusher. The wear-resistant lining board adopts domestic advanced wear-resistant materials, which has the advantages of long service life, not easy to damage, and convenient maintenance. The continuous service life can reach more than one year. When the wear is serious, the cover can be replaced by removing the cover. The amount of maintenance is small and the cost is low, which is unmatched by any other type of crusher in China. 7. The roller crusher is equipped with a safety protection device. When an accidental metal iron piece enters the crushing cavity, the protection device acts and the iron piece leaks out of the equipment to operate normally. 8. The roll gap of the grinding roller body of the roller crusher can be adjusted arbitrarily from 1mm to 20mm. After adjusting the roll gap according to the requirements of the crushing particle size, the crushing particle size can be reliably controlled, and all are discharged from below the crushing cavity with the ideal particle size. 9. Simple and reasonable structure, low operating cost, stable operation, high efficiency and energy saving, high crushing efficiency, adjustable output granularity. 10. The roller crusher is the working principle of low speed and high pressure roller extrusion. The material falls vertically into the crushing cavity from the upper part of the crusher, and is crushed by the strong pressure generated between the two rollers. Most of the material has become powder, and a large number of cracks have occurred in the remaining small portion of granular material. In the further crushing process, it can greatly reduce the grinding energy consumption and increase the output.

The double roller crusher uses high squeezing force generated by the relative rotation of two high-strength wear-resistant alloy crushing rollers to crush the material. After the material enters the gap between the two rollers (v-shaped crushing chamber), it is crushed by the relative rotation of the two crushing rollers Under the action of pressure and shear force, the material is crushed into the required particle size and discharged from the discharge port under squeezing, shearing and grinding.If the compressive strength of the material exceeds 250mpa, it is recommended to choose an energy-saving roller pressing (grinding) machine, which is divided into two methods: triangle belt and coupling transmission (hard link) according to user requirements. If there is no electric power in the mine plant , it can be changed to diesel or gasoline engine as power.
