The main types of crushers include jaw crushers, impact crushers, cone crushers, and heavy-duty hammer crushers.

　　1. Jaw crusher: Mainly used for crushing and processing various hard rocks, ores and other materials. The jaw crusher crushes materials through the mutual movement between the fixed jaw plate and the movable jaw plate. The material is * sent into the feed port and then crushed between the movable jaw plate and the fixed jaw plate. The periodic movement of the movable jaw plate will release the material pressure and make the crushing effect better.

　　2. Impact crusher: used to crush and process various medium-hard rocks and ores. The impact crusher projects the material onto the impact plate through the high-speed rotation of the rotor. The material generates high-speed impact between the impact plate and the rotor, thereby crushing the material. The broken material is discharged from the machine through the discharge port.

　　3. Cone crusher: Mainly used for fine crushing and crushing of rocks and ores with medium hardness or above in mining, construction, metallurgy, chemical industry and other industries. There is a fixed cone and a rotating cone (moving cone) in the crushing cavity of the cone crusher. The material enters the crushing cavity from the feed port and is squeezed, ground and crushed under the rotation of the cone. . The crushed materials are discharged through the discharge port.

　　4. Heavy-duty hammer crusher: Crushing equipment used to crush and process large or hard rocks, ores, construction waste and other materials. Heavy-duty hammer crusher consists of hammer head, rotor and screen. The hammer head is fixed on the rotor, and the hammer head impacts and crushes the materials through the movement of the high-speed rotating rotor. The materials are * loaded into the feed port, and then crushed into gravel of the required size by the hammer under the action of the rotating rotor.
