Roller crusher Coarse stone roller crusher is a high-efficiency crushing equipment designed for processing larger size stones, which is widely used in mines, quarries, sand and gravel aggregate production lines and other occasions. The equipment is mainly composed of a pair of high-strength, high-wear-resistant rolling rollers, which generate a huge extrusion force through relative rotational movement to achieve the crushing of coarse stones.
Its working principle is based on the extrusion crushing method, when the coarse stone enters between two rollers, it is continuously extruded, sheared and ground to be crushed into the material of the required particle size. One of the advantages of the roller crusher is that the gap between the two rollers can be adjusted as needed to precisely control the particle size of the crushed material to meet the application needs of different fields.
The coarse stone roller crusher has the characteristics of strong processing capacity, large crushing ratio and uniform discharge particle size, especially suitable for crushing coarse stone with moderate hardness, such as limestone, granite, pebbles, etc. At the same time, the equipment is manufactured with excellent wear-resistant materials, which has a long service life and low maintenance cost. In addition, some advanced models are equipped with hydraulic or spring protection devices, which can automatically adjust the roller spacing in case of unbreakable objects or overloads, so as to avoid damage to the equipment and ensure production safety.
In short, the coarse stone roller crusher has become an ideal choice for coarse stone crushing operations with its high efficiency, energy saving, durability and safety and reliability.
