Double-roll crusher, a kind of mining machinery, also known as double-roll crusher, pair-roll crusher, roller crusher, is mainly used for crushing ore. The machine has small size, large crushing rate, low noise and simple structure , Convenient maintenance and other advantages, characterized in that the crushed material has uniform particle size, low pass rate and convenient maintenance. Safe and reliable. It is suitable for coal, metallurgy, mining, chemical, building materials and other industries in large coal mines or coal preparation plants. It is more suitable for crushing raw coal (including stones). The toothed roller crusher has a large crushing capacity, and the motor and the reducer pass through a limited distance fluid coupling The device is connected to prevent power overload and protect the sensor from overload, which is safe and reliable. The pitch of the toothed roller is adjusted hydraulically, the bearing of the toothed roller shaft is lubricated, the tooth shape is optimized, and the tensile and shearing selection is broken, high efficiency and low consumption, uniform grain output, and good grain shape.

How to choose a roller crusher

Roll crushers can be divided into single-roll crushers, double-roll crushers or four-roll crushers according to the number of rolls. Double-roll crusher, also known as double-roll crusher and double-roll crusher, is the most common crusher. According to the speed of the rollers, the double roller crusher can also be divided into fast and slow roller crushers. A crusher that uses the same rotating roller squeezing force to pulverize ore for coarse, medium and fine crushing. It consists of a motor, a bracket, a fixed roller, a movable roller and a safety spring. The double-roll crusher is mainly used for processing viscous materials, most of which are two rollers with different diameters. The basic structure of the roller crusher is a work roll and a wear-resistant roll. There is a spring or hydraulic adjustment mechanism behind the work roll bearing seat, which is used to adjust the size of the discharge port. At the same time, it is used as a protection device when overloaded, and there is a transmission system. , Feeding device and feeding device. The main parameters that affect the production capacity and transmission capacity of the crusher are the engagement angle, the feed size and the roller speed. The roller crusher has large power, and the roller crusher with a small discharge port can effectively crush the material superfinely. Under the action of friction, the working roll suitable for the rotation of medium crushing viscous stone is pulled into the crushing cavity by friction, so that the material is crushed under the action of squeezing force, and the rotating roll is taken out of the crushing cavity and discharged as the crushed finished material. There are two types of smooth roller surface and non-smooth roller surface on the roller surface of the roller crusher. Smooth roller surface handles hard materials; non-smooth roller surface has grooves or teeth, and is usually used to crush brittle materials such as coal. The surface of the roller is mostly smooth, and the bearing of the movable roller can move along the frame and has a strong safety spring. Before normal use, gaskets should be used to adjust the gap between the two rollers to ensure the crushing rate.
