Roll crusher manufacturer - Henan Dajia Minerals roll crusher (double roll crusher) applies to cement, chemicals, power, mining, metallurgy, building materials, refractory materials, coal and other industries coarse brittle bulk materials Intermediate broken, its feed size, discharge size adjustable, compressive strength ≤160MPa material crushing. Especially coal industry, using the crusher coal, long after iron, cleaning, do not except refuse, can be directly crushed, broken out of the material, uniform size, low over the ground, thus simplifying the coal preparation process and reduce investment and production costs. In recent years, with the development of the technological level of production and construction as well as the continuous improvement in the structure of the roll crusher and grinding processing has improved and new developments, such as grading crusher, roller press, making the roll crusher application We continued to expand and develop rapidly. To building materials, coal, chemical and mineral processing industries, creating conditions for energy saving, and to bring high efficiency. Structure and performance characteristics of the roll crusher the crushed material through the feed opening falls between two rollers, squeeze broken down naturally finished materials. When the event was perfect or not broken, roll crusher rolls present their spring-action hydraulic cylinder or automatic concessions, the roller gap increases, hard or not breaking things down, to protect the machine from damage. Turn toward the two rollers have a certain gap, changing the gap, you can control the product's largest nesting size. Double roll crusher is using a pair of opposing rotating round roll, four roll crusher is to use two pairs of opposing rotating circular roller crushing. 1, the series of roll crusher mainly consists of roller, roller support bearings, pinch and adjust parts of the device and the driving device and other components. 2, the expected size of the adjustment: fitted with the wedge between the two rollers or shims top device, the device is equipped with wedge adjustment bolt, when the adjustment bolts pull up wedge, wedge away from the active roll top fixed wheels, namely two roller gap becomes larger, the expected size becomes larger when the wedge down activities roller compression spring under the effect of two rounds of the gap becomes smaller, the smaller particle size. Spacer means is by the number or thickness of shims to adjust the particle size of the material, while increasing both the gasket roller gap larger, while reducing gasket two roller gap smaller, the smaller particle size . 3, the drive mechanism is composed of two motors through V-belt drive to the sheave drag roller, rotates in the opposite direction. When broken material, the material from the inlet through the roller, the roller compacted and broken, finished after crushing discharged from the chassis below. 4, for security, transmission security cover should be installed according to the actual situation.
