The role of stone crusher is crushing the large size of the stone into different sizes of small gravel, after meet the requirements applied to the project. Highway for the quality requirements of stone is more stringent.
Jaw crusher is mainly consist of the fixed jaw plate and the activities of the jaw plates, the working principle is activities of the jaw plate on the fixed jaw plate for periodic reciprocating motion, the stone was crushed by the two jaws. They can crusher the stone that with great hardness and large size, but the discharging-material size is large. Generally used as a stone of coarse crushing.
Hammer crusher mainly consist of hanging hammer and rotary table, the working principle is the hammer that freely hanging on a turntable driven by rapid rotation of the turntable rotation, the stone was hit by the rotation of the hammer and crushed. It is suitable for crushing the hard stone, which is characterized by low machinery cost, high production efficiency. But after crushed the high content of gravel pin sheet is not suitable for highway projects.
Impact crusher is mainly consist of rotor, hammer and counterattack plate, its working principle is stone was smashed by high-speed rotating flat hammer, and flying out hit the counterattack plate to the further crushing. It is suitable for crushing the hardness of stone, the aggregate particle size is uniform and close to the cube, less content of gravel pin sheet.
From this the impact crusher is the ideal processing equipment for construction of high-level road, especially suitable for crushing the hard rock, high efficiency and energy saving; cubic product shape, adjustable discharging particle size and simplifying the crushing process. Because of Its excellent performance and good performance, it is widely used in highway construction, hydraulic engineering, gravel processing construction and other fields
