Dryer is mainly used for materials with certain humidity or granularities in the field of beneficiation, building materials, metallurgy, etc.It has been widely used due to its great adaptability towards various raw materials, simple structure and reliability.
The jaw crusher is drived by motor through belt and belt wheels, which makes the movable jaw plate up and down through eccentric shaft.When the movable jaw comes down, the angle between the fixed jaw plate and the movable jaw plate gets smaller, then the materials can be crushed .When the movable jaw plate rises, the angle becomes lauger and the movable jaw plate leaves the fixed jaw plate with the function of tie bar and spring.At the same time the final products are discharged from the lower outlet of the crushing chamber.
Specification
This series of products have the advantages of big reduction ratio, even granularity, simple structure, liable operation, easy maintenance, economic operation cost, etc. It is widely used for materials with the max crushing compressive strength not more than 320 mpa in the field of mine, metallurgy, building materials, roads, railways, irrigation, chemical industry, etc.
Features
It has the characteristics of novel structure, no-bond connecting, high chrome plate hammer, special impact lining plate and energy saving.The finished product is in cubical shape and the discharge granularities can be adjusted.It simplifies the crushing process.
Operating principle
Impact crusher is a kind of crushing equipment which uses impact energy to crush maters.When getting into the effective area of hammer plates, due to the high speed of striking, the raw materials are thrown onto the impact equipment which is installed above the rotor.Then the materials are rebounded to the effective area of hammer plates and crushed again in the crushing chamber . At last, when the particles reach to the proper size, they will be discharged from the bottom of the machine.
Pf impact crusher series
The series of products can deal with the materials with max length below 500mm, and the compressive strength below 350mpa. They have the advantage of greater reduction ratio and the final materials are in cubical shape.
The low speed transmission is convenient for maintenance and starting.And the oil mist spray lubrication device ensures the reliable lubricating of big and small gears.Generally, the main motor of the large mill is high pressure asynchronous motor or synchronous motor.So customers should indicate the motor type in order.
Adopting advanced structure of the similar products in foreign countries, the high-rate raymond mill is designated on the basis of modification and renovation of large scale raymond mills. Compared with ball mills, the high-rate raymond mill has higher efficiency, lower power consumption, and smaller area occupying and smaller lump-sum investment. Due to the centrifugal force, the roller mills grind tightly on the rings. Thus it will not influence the output and granularity of the finished products even when the roller and the ring have wear-out in some degree.
It is designated for processing superfine powder of over 300 noninflammable and nonexplosive materials with mohs hardness below grade 8 and water content below 6% in the field of mine , chemical industry, building materials, such as barite, calcite, potash feldspar, steatite, marble, limestone, dolomite, fluorite, lime, active carclazyte, active carbon, bentonite, kaolin, cement, phosphorus ore, gypsum, glass, manganese ore, titanium ore, copper mine, chrome ore, refractory materials, heat preservation materials, coal coke, coal fines, black, , bone meal, titanium white powder, , quartz, and so on. The finished products can be adjusted freely from 80 to 325 meshes with max meshes of 600 for some materials.
