Application scope: mining, coal mining, sand and gravel quarry, concrete mixing plant, dry mortar, power plant desulfurization, building materials, smelting and so on.

Products

Sand and gravel are large in size and high in hardness after mining, so they need to be crushed by sand and gravel crusher. Sand and gravel crusher is the favored equipment in the integration of mines, and it is the trend of future development. From the stone crushing into gravel, even for the aggregate requirements of finer when the stone has to be crushed into finer particles to be used on the construction. It can be seen that the purpose of choosing a sand and gravel crusher is ultimately to get the needed materials for construction. They are often not used alone, but as a chain in a stone production line or sand production line.

Commonly used gravel crusher equipment often refers to the jaw crusher, which is the preferred equipment when used in engineering. No matter from the output or particle size requirements, crushing hardness, almost all can be satisfied. Sand and gravel crusher can be used for coarse or medium crushing operation of various ores and large materials with compressive strength not exceeding 320Mpa, with feed size of 125mm～1020mm, featuring large processing size, low production cost, etc. It is a better choice for primary crushing.

Working Principle

PE series jaw crusher crushing mode is curved extrusion type, the motor drive belt and pulley, through the eccentric shaft to make the movable jaw up and down movement, when the movable jaw rising elbow plate and the movable jaw between the angle becomes bigger, so as to promote the movable jaw plate to the fixed jaw plate close, at the same time, the material is crushed by the extrusion, rubbing, crushing and other forms of crushing; when the movable jaw downward, elbow plate and the movable jaw between the angle becomes smaller, the movable jaw plate in the action of the pull rod, the spring to leave the fixed jaw plate, at this time the broken material has been crushed, and then the crushed materials are crushed, and then the jaw board is crushed, and then the material is crushed, and then the crushed materials are crushed. When the angle between the elbow plate and the movable jaw becomes smaller, the movable jaw plate leaves the fixed jaw plate under the action of pull rod and spring, and then the crushed material is discharged from the lower mouth of the crushing chamber, and the movable jaw is crushed and discharged periodically with the continuous rotation of the motor to realize the mass production.
