Grate plate is mainly used in devices such as hammer crusher, grinding machine, because this kind of crusher are impingement and broken form, therefore, crusher grate plate in collisions with the impact of the material is easy broken, so jade litres of casting in the research and development of gas plate using high manganese steel and other materials, greatly enhance the toughness and wear resistance, the crusher material being back to the plate and gas by secondary crushing, To ensure better screening of broken products.
The vulnerable parts of hammer crusher are grits, the main reason for grits damage is the impact and wear of materials. When hard or non-broken materials enter the crushing chamber, it will also aggravate the blocking of grits, and the load of grits will be aggravated in the crushing chamber, which is easy to cause damage to the grits. If the screen plate wear is serious or fracture, it will cause the discharge particle size is too large, if the screen plate gap is blocked, feeding is not uniform, it will cause the hammer machine production reduction, at this time to clean up the plug in the screen bar gap, adjust the feeding structure. The reinforcing plate height of hammer crusher is reduced to 50mm higher than the labyrinth as a standard, and the reinforcing plate which is conducive to strengthening the strength of the reinforcing plate can be welded on the side of the reinforcing plate, so as to effectively strengthen the wear-resisting ability of the labyrinth and the ability to fight against hitting; The operator often checks the labyrinth in the production process. If any abnormal sound is found, the labyrinth needs to be stopped and checked. The foreign body is removed from the crusher chamber to avoid damage to the labyrinth.
The circular discharge screen is installed under the rotor, the two ends of the grate are installed on the beam, and the grate is pressed with a pressure plate. The direction of the grate is perpendicular to the direction of the rotor movement. The space between the grates is formed by the protrusion between the grates. To facilitate material discharge. The gap between the grates gradually expands downward and tilts to the direction of rotor rotation.
