There are many types of stone crushers, such as jaw crushing, counterattack crushing, cone crushing, impact crushing, hammer crushing, roller crushing and so on. Although these crushers are all stone crushing equipment, their working principles and crushing methods are different, so their positions in the entire crushing process are also different. Today, Xiaokuang will give you a summary of the crushing methods of commonly used crushers.
The first type: curved extrusion type, representing jaw crusher
Jaw breaker is a motor driven belt and pulley, which makes the movable jaw move up and down through an eccentric shaft. Its crushing method is a bit similar to chewing on the upper and lower jaws. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, which pushes the movable jaw plate closer to the fixed jaw plate. Purpose;
When the movable jaw descends, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and the spring. At this time, the crushed materials are discharged from the lower mouth of the crushing cavity.
The second type: laminated crushing type, representing cone crushing
The cone crusher is driven by the motor to drive the belt pulley or coupling, so that the drive shaft drives the eccentric sleeve to make a rotary motion. The crushing wall of the cone crusher is close to and away from the wall of the rolling mortar from time to time, so that the ore is continuously impacted, squeezed and bent between the two to achieve crushing.
The third type: impact crushing type, which represents counterattack and hammer crushing
The impact crushing mainly uses the blow and crushing of the plate hammer. For example, counterattack. Driven by the motor, the rotor rotates at a high speed. When the material enters the action area of the blower, it is hit and crushed by the blower on the rotor, then thrown out, and then continue to be beaten and crushed. Through continuous beating and crushing, the material is slowly broken into the required particle size and discharged from the discharge port.
