The hammer crusher devided into single rotor and double rotor. The single rotor is divided into two types: reversible and irreversible. Single rotor hammer crushers and ring hammer crushers are widely used.
Hammer crusher box body, rotor, hammer head, counterattack lining plate, sieve plate and so on.
Several rows of hanging hammers are installed on the main shaft of the crusher. A pin shaft runs through the pin hole in its circumference, and the hammer is hinged between each row of hanging hammer bodies with the pin shaft. After the hammer is worn, the working surface can be replaced. There are two trapped pin holes on the hanging hammer body. The distance from the center of the pin hole to the center of the rotation axis is different, which is used to adjust the gap between the hammer and the grate. In order to prevent the hanging hammer body and the hammer from moving in the platinum direction, the two ends of the hanging hammer body are fixed with pressing hammer discs and locking nuts. It is supported on rolling bearings at both ends, and the bearings are fixed on the casing with bolts. The main shaft and motor are directly connected with elastic coupling. To make the rotor run smoothly, a flywheel is mounted on one end of the main shaft.
The arc-shaped discharge screen is installed under the rotor, the two ends of the grate are installed on the beam, and the grate outside the member is pressed by the pressure plate, and the arrangement direction of the grate is perpendicular to the movement direction of the rotor. The grate gap is formed by the protruding part in the middle of the grate. In order to facilitate material discharge. The gap of the grate gradually expands downward, and at the same time it is inclined to the rotation direction of the rotor.
Motor drives the rotor quickly in the crushing cavity. Raw materials enter the crusher through the feeding inlet and are impacted, cut and ground by high-speed hammer heads. There is a grate under the rotor assemblly, so that materials with size smaller than the grate mesh will be screened out and others are left to be further hammered until they reach the standard size. The size of the final product can be adjusted by changing the grate, the gap between the rotor assemblly and the grate can also be adjusted according to different requirements.
Hammer crusher Installation and test drive
1. Before installation, the terrain can be selected according to the source of raw materials.
2. The machine is fixed on the concrete by anchor bolts. When designing the foundation, a ore discharge slot should be reserved, and its slope should not be less than 50°, but the user can also customize it according to the feeder and transportation equipment.
3. The motor should be installed in the opposite direction to the feeding port.
4. The location of electrical equipment should be convenient to use.
5. Before commissioning, check whether the fasteners are completely firm.
6. Check whether metal objects or other unbreakable sundries fall into the body.
7. Check whether there is proper lubricating oil in the bearing.
8. Rotate the rotor by hand to see if it is normal and whether there is friction. If it is confirmed that the movement is unobstructed, the car can be started empty. After half an hour of testing, there is no noise, no swing, and the temperature rise of the bearing does not exceed 30 °C. Carry out a load test.
