Crusher, history can be traced back to the 1850s from the birth of the first jaw crusher in the world for a long time has passed. With the development of the productive forces, jaw crusher has been unable to fully meet the needs of crushing technology, so Double Roll Crushers characteristics, based on jaw crusher, it has designed a crusher. In 1924, the German first developed a single, dual-rotor two types of crusher, crusher structure then similar to the modern squirrel cage crusher, because in terms of the structure, or the analysis from the works It has the characteristics of both the crusher. As the material requires repeated shocks, crushing process can be free and unimpeded discharge, but due to restricted material strength and impact crusher capacity, gradually transforming its model for squirrel cage crusher. Uses crushing ratio (typically 10-25, the higher up to 50), high production capacity, product uniformity, less excessive phenomenon, low energy consumption per unit of product, simple structure Double Roll Crushers pictures, light equipment quality Double Roll Crushers machine, easy operation and maintenance and so on. Stone crusher is directly 600-1800 mm maximum particle size of the material crushed to a period of 25 or 25 mm below the broken stone crushing machine. Suitable for cement, chemicals, power, metallurgy and other industrial sectors crushing medium hardness material, such as limestone Double Roll Crusher, slag, coke, coal and other materials in the debris, crushing operations. For crushing all kinds of hard and abrasive weak materials. Compressive strength of the material does not exceed 100MPa, moisture content less than 15%. Material to be broken coal, salt, chalk, gypsum, brick, limestone and so on. Also used broken fiber structure, strong flexibility and toughness of broken wood, paper or broken asbestos cement waste to recover asbestos fibers and so on.
