Roll crusher also called on the roll crusher, double roll crusher, roll crusher, is the use of the roller surface friction material will be broken into bite ring hammer crusher structure diagram, so bear squeeze or split and broken machinery. Roll crusher usually divided by the number of roller single roll, double roll and multi-roll crusher is mainly used in mining, metallurgy, chemical industry, coal industry coarse brittle bulk materials, intermediate crushing, feed their large size, the expected size adjustable ring hammer crusher structure, compressive strength of the material ≤160MPa crushing. Especially in the coal industry, the use of the raw coal crusher, long after iron removal, cleaning, no addition to the waste rock, can be directly broken ring hammer crusher, crushing the material, uniform size, broken too low, thus simplifying coal preparation process, reducing investment and production costs. Crusher, has a simple structure, large crushing ratio, low power consumption, high output, low weight, cubic shape after the crushing finished, it is widely used in a variety of ore crushing, railway, highway, energy, cement, chemicals , construction and other industries. Crusher is a rebound effect of the use of high-speed impact hammer plate and back plate, so that the material by repeated shocks and broken machinery. Hammer solid plate mounted on the high-speed rotation of the rotor Xin Li ring hammer crusher, crushing chamber and along a number of different angles layout block counterattack plate. Material into the role of district board hammer hammer when first being broken for the first time while the initial impact, and at the same time to get momentum, high speed toward the back plate. Materials and back plate collision broken again after being bounced back to hammer action area, again by plate hammer impact. This is repeated until the desired size is broken into and from the plane. Compared with the hammer crusher, impact crusher crushing ratio greater and more fully utilize the high-speed impact energy throughout the rotor. However, due to plate hammer easy to wear, it is also limited in the hard material crushing applications, usually used crushing, breaking or crushing limestone, coal, calcium carbide, quartz, dolomite, iron pyrites, gypsum and chemical raw materials hard brittle materials such as the following.
