What kind of crusher is good for hard rock?
At present, the crushers on the market include extrusion type, laminated crushing type, impact type, stone-on-rock and stone-on-iron crushing methods, among which extrusion type and laminated crushing type are more suitable, because the impact type is easy to damage the hammer and has a long service life. Short, how does a concrete hard rock break?
The crushing cavity is composed of two jaw plates, the movable jaw and the static jaw, and the crushing operation is completed by simulating the movement of the two jaws of animals. The motor drives the belt and the pulley, and the movable jaw moves up and down through the eccentric shaft. When the movable jaw rises, the toggle plate and the movable jaw are clamped. The angle becomes larger, so as to push the movable jaw plate close to the fixed jaw plate, and at the same time, the material is crushed or chopped to achieve the purpose of crushing; when the movable jaw moves down, the angle between the toggle plate and the movable jaw plate becomes smaller, and the movable jaw plate Under the action of the pull rod and the spring, it leaves the fixed jaw plate, and the crushed material is discharged from the lower opening of the crushing chamber.
How can a hard stone be broken? Therefore, it is generally better to choose equipment such as jaw crushers and cone crushers, which not only meet industry standards, but also meet the needs of use.
The jaw crusher can start crushing the material at the upper part of the crushing chamber, and the lower part of the crushing chamber has a larger stroke and a larger crushing ratio. At the same time, the integrated structure of the motor base and the main machine makes the installation easier and saves space. In addition, for this A kind of high-hardness stone material, key components such as jaw plate and lining plate are all made of high-manganese steel and high-quality alloy materials, and the whole machine is durable.
The cone crusher adopts a hydraulic cavity cleaning system, which reduces the downtime, and each specification of the crusher has many cavity types. Users can choose different cavity types according to different needs, so as to better meet the needs of users. The crushing wall, rolling The vulnerable parts such as the mortar wall and lining board are also made of manganese steel, which solves the problem of high operating costs in the later stage of processing hard stones and prolongs the service life.
