Impact crusher

Impact crusher structure

Impact Crusher produced by Hongxing Machinery mainly consists of seven parts: feed, distributor, vortex crushing chamber, impeller experience, spindle assembly, base transmission and motor.

Impact crusher works

Materials into the crusher from the hopper, the material will be divided into two parts by the feeder, part of the intermediate feeder into the high-speed rotating impeller, the impeller is rapidly accelerated, the acceleration of up to hundreds of times the acceleration of gravity, and then The speed of 60-70 m / sec from the impeller three uniformly distributed within the channel ejection, the first with the material from the feeder around the falling part of the impact of broken materials, and then together to impact the material inside the vortex branch lining, It is rebounded by material lining and diagonally strikes the top of the whirling chamber and changes its direction of movement to deflect downwards. The material emitted from the impeller runner forms a continuous material curtain. Such a material in the vortex crushing cavity twice to hit the probability of multiple occasions, friction and grinding crushing, crushed material discharged from the lower discharge port, and the formation of closed loop screening system, the general cycle of three can be Broken into 20 items below the material. Throughout the crushing process, the material impact each other crushing, not in direct contact with the metal components, but with the material lining impact, friction and smash, which reduces the angle pollution, to extend the mechanical wear time, whirlpool cavity ingenious Air circulation, eliminating dust pollution.

Impact crusher routine maintenance and safety technology

1, shut down regularly, open the observation gate inspection crusher internal parts wear, the wear lining, lining, impeller runner lining, the circumference of the wear plate and wear resistance, wear and tear should be promptly replaced or repaired , Wear-resistant block wear should be replaced at the same time a full set to ensure that the impeller running balance and found that the impeller body wear and tear should be promptly replaced or factory repair.

2, open the observation hole is strictly prohibited when the crusher work to observe the internal work, so as to avoid danger.

3, the crusher uses 3 # lithium grease or molybdenum disulfide (MoS2) grease, adding the amount of bearing cavity 1 / 2-1 / 3, the crusher work 400h adding the right amount of grease, work 2000h open the spindle assembly The bearing cleaning, work to 7200-10000h should be replaced with a new bearing, the upper spindle bearing assembly for the swimming end, the bottom bearing for the fixed end, the assembly of the hand after the pulley should be able to rotate flexible.

4, drive V belt tension should be adjusted to fit the size of the V belt to ensure uniform force, double motor drive, V-belt on both sides should be grouped, so that each group as long as possible, should be adjusted so that the two motors Current difference does not exceed 15 amps.

5, PL-type crusher is a high-speed operation of equipment, crusher operation should pay special attention to safety in production, the operator should operate in the designated positions, unrelated persons should be away from the equipment, if the need for machine repair, should be carried out after the shutdown.
