European Impact Crusher
As a large and medium-sized crushing equipment that uses impact force to crush ores, the European impact crusher is more and more widely used in building materials, metallurgy, mineral processing, chemical industry and other industries. It can be used to crush limestone, coal, sandstone, cement clinker, iron ore, aluminum ore, molybdenum ore and other materials in coarse crushing, medium crushing and fine crushing. Due to the remarkable crushing effect of European impact crusher, it can replace jaw crusher, roll crusher and cone crusher in some small and medium-sized plants and mines.
Precautions for maintenance of the European Impact Crusher:
(1)During the operation of European impact crusher, routine inspection should be made frequently. When abnormal sound or bearing temperature is found to be higher than 700C, the machine should be stopped immediately for inspection and the fault should be eliminated in time before the machine is started.
(2) Feeding should be done only after the machine is running normally, and feeding should be done evenly to prevent mixing with hard iron. Before stopping the machine must first stop feeding, stopping the motor again after the material crushing.
(3) The impact crusher should rotate the rotor with human power after the maintenance or adjustment of the discharge opening, to confirm that the rotor and other parts do not have friction and jamming phenomenon and can rotate flexibly before starting the motor.
(4) should always check whether the bearing seat seal is good, the bearing seat grease should be filled once a month, every three months should be all cleaned and replaced oil felt.
(5) in checking whether the fasteners are loose, should focus on checking the rotor on both sides of the pressure plate hammer pressure plate screws, to prevent the pressure plate is loose, the ends of the plate hammer exposed rotor body, and the body banging, damage the machine parts.
(6) To ensure the safety of the operator and the equipment, it is forbidden to carry out repair, adjustment and cleaning work while the machine is running, and to open various small doors.
(7) When the size of the crushing product is too large, the machine should be stopped to check the wear of the plate hammer to prevent the rotor from being worn out. When the plate hammer needs to be adjusted 180 due to wear and tear, each plate hammer should be made equal in weight and balanced to prevent vibration after the machine is started.
European Impact Crusher Applications:
The plate hammer and rotor of the European Impact Crusher are rigidly connected and have a large crushing cavity so that the material has some room to move. The crusher uses the rotor rotating at high speed to impact the material, and the material is not only crushed under the action of the plate hammer, but also obtains large speed and kinetic energy, and impacts to each impact plate on the frame in the crushing cavity, or impacts between the material blocks and each other to achieve material crushing. As early as 1965, the Anshan Coking Refractories Design and Research Institute tested the impact crusher to crush coking coal. It was compared with cage crusher and hammer crusher in terms of production capacity, power consumption, maintenance and other aspects. The impact crusher was found to be superior to the cage crusher and hammer crusher in all these aspects. The impact crusher not only has a simple structure, low power consumption and large crushing ratio, but also has unique advantages in terms of uniform product size. Therefore, it has been widely used in metallurgy, coking, chemical industry, construction materials, refractory materials and other industrial sectors.
