subject: Impact Crusher Enhances Secondary Crushing Effect [print this page] Studies have shown that the increased moment of inertia of the rotor, speed can be increased by the crushing force, and improve crushing efficiency; to improve the angle of the back plate can be increased secondary crushing effect of the materials.
Stone production line, sand making production line, the crusher is the second or the third process, after the jaw crusher crushing large material to the crusher again after broken into customer needs 20 ~ 60mm particles. The crusher is a use of impact energy to broken machinery. In order to ensure the crusher in the production line in the sand better in continuous operation, continuation of the life of the crusher, users should carry out regular maintenance and upkeep of crusher.
The new machines put into operation; each class is completed crusher conduct a comprehensive inspection. Conduct a comprehensive inspection after the weekly run impact crusher motor, lubrication. Check the contents of the fixed parts of the fastening belt drive, bearing seals, counterattack liner, liner wear and tear the whole place checks, combined with the maintenance cycle to establish a regular maintenance and replacement system. Crusher gap adjustment of the rotor and counter lining: when the crusher rotor running clearance between the rotor and counter lining cannot be adjusted. If the material into blocks stranded in between the back plate and the plate and shell, it is recommended to lift slightly re-adjust the gap between the impact racks, so into a feed become loose, easy to adjust the impact rack. If the counter-attack aircraft enough, you can relax the lever on the tap (with a piece of wood protection), the clearance of the rotor and counter-lining is done by the adjusting device of the machine, first loosen the bolt, and then in turn the long nut, this when the lever upward direction of movement, adjustment Fortunately, the screw sets fastening.
With the development of large bridges, large office buildings, subway tunnel, and other buildings in China increasingly updated, especially in recent years, high-speed railway construction in a very important position. For highway construction, large-scale railway construction investment, long construction period, broad in scope and more effectively promote the market of building materials, construction machinery. All the buildings are not from the aggregate and concrete aggregate use, and in accordance with the new operating metrics, new concrete and gravel aggregate, grain type, gradation, have raised more higher requirements It can be said is completely in accordance with international standards.
