product details

Double-roll crusher is divided into two-roller and four-roll crusher, suitable for the crushing operation of medium hardness materials, such as: coking coal, sinter, limestone, various metal ores and non-metallic ore. Double-roll crushers is most suitable for medium and fine crushing operations in small and medium-sized non-metallic mines and chemical industries. The minimum particle size can reach 100 mesh or less. The Double-roll crushers has a simple structure and is easy to operate. It can achieve the ideal crushing granularity by adjusting the gap of the crushing roller. The performance is stable, and the phenomenon of over crushing can be avoided.

 

working principle

 

Double-roll crushers crusher is a commonly used roller crusher, and its crushing mechanism is a pair of cylindrical rollers horizontally mounted horizontally on the frame. The front roller and the rear roller rotate towards each other, the material is added to the feeding box, and falls on the top of the roller. The material is pulled into the roller between the rollers under the action of the friction force on the roller surface and is crushed by the roller. The Double-roll crushers material is pushed out of the roll and unloaded downwards. Therefore, crushing is continuous operation, with the role of forced unloading.
