Rock Crushing Machine structure


The Rock Crushing Machine is mainly composed of a fixed jaw, a movable jaw, a frame, an upper and lower guard plate, an adjustment seat, and a moving rod. It is widely used in medium-sized crushing of various ores and bulk materials in mining, smelting, building materials, highway, railway, water conservancy and chemical industries. The high compressive strength of the crushed materials is 320Mpa. It is mainly composed of two jaws, which are composed of two jaws, which are composed of two jaws, which simulate the two movements of the animal and complete the crushing operation of the material crushing operation. The following is a detailed process of the working principle of the Rock Crushing Machine:

When the Shanghai Shibang machine Rock Crushing Machine is working, the movable jaws periodically reciprocate the fixed jaws, sometimes close, and sometimes leave. When approaching, the material is crushed by crushing, splitting, and impact between the two jaws; when leaving, the material that has been broken is discharged from the discharge port by gravity.

When feeding the Rock Crushing Machine, the material is poured from the top inlet into the crushing chamber with the molars. The molars push the material to the chamber wall with great force and break it into smaller stones. Driven by the motor drive belt and the pulley, the eccentric shaft is moved up and down by the eccentric shaft. When the moving jaw rises, the angle between the bracket and the moving jaw becomes larger, thereby pushing the movable jaw to approach the fixed jaw, and at the same time the material Multiple crushing, crushing, rolling, etc.; when the moving down, the angle between the bracket and the moving jaw becomes smaller, and the moving jaw leaves the fixed plate under the action of the tie rod and the spring. At this time, the broken material is broken. The lower chamber is discharged, and the mass production can be realized as the motor is continuously rotated to periodically crush and discharge the movable jaw.

The Rock Crushing Machine consists of two jaws, which are composed of moving jaws and static jaws, which simulate the crushing machine of the material. The high compressive strength of the crushed material is 320Mpa. It has the characteristics of large crushing ratio and uniform product size, and is widely used in mining, smelting, building materials, highway, railway, water conservancy and chemical industries. So, what are the main structures of the Rock Crushing Machine?

Fixed part

1. Rack: The frame is a four-wall rigid frame with upper and lower openings. It is used to support the eccentric shaft and bear the reaction force of the broken material. It requires sufficient strength and rigidity, and is generally cast in cast steel. The frame of the mainframe needs to be cast in sections, and then bolted together to form a whole, and the casting process is complicated.

2. Side guard: The side shatter of the Rock Crushing Machine is located between the fixed tooth plate and the movable tooth plate. It is a high-quality high-manganese steel casting, which mainly protects the equipment frame wall in the whole body.

Transmission component

1. Seesaw: The seesaw is the wear-resistant part inside the Rock Crushing Machine, which is mainly divided into the jaw plate and the movable jaw; after the material enters the inside of the Rock Crushing Machine chamber, the fixed jaw and the movable jaw are squeezed before and after. Press to break the material.

2. Eccentric shaft: It is the main shaft of Rock Crushing Machine, which bears huge bending and torsion force. Therefore, Shanghai Shibang machine is made of high carbon steel, which can reduce wear and improve work efficiency. In the device, the pulley is mounted at one end of the eccentric shaft and the flywheel is mounted at the other end.

3. Flywheel: The flywheel of the Rock Crushing Machine is used to store the energy during the moving stroke, and then used for industrial formation, so that the work of the machine tends to be uniform. The pulley also plays the role of a flywheel. The flywheel is often made of cast iron or cast steel, and the flywheel of the minicomputer is often made in one piece. Flywheel manufacturing, pay attention to static balance when installing.

Other parts

1. Adjusting device: The adjusting device has wedge type, pad type and hydraulic type, etc. According to the specific working conditions, the adjusting device suitable for the operation is selected.

2. Lubrication device: The eccentric shaft is usually lubricated by concentrated circulation. The support surfaces of the mandrel and the thrust plate are generally greased by a manual oil gun using grease. The lubrication device helps the Rock Crushing Machine to regularly add grease to prevent wear and tear on components.
