How does the impact crusher maintain? How long does it take to maintain it?
1, regular shutdown, open the door to observe check crusher internal parts wear. Wear ring lining, lining, lining, circumferential expansion impeller plate and wear-resisting block wear, wear should be promptly replaced or repaired, wear-resisting block wear should be replaced at the same time to ensure the full set, impeller balance, find the impeller body please wear should be replaced or repaired.2, strictly prohibit the crusher work, open observation hole, observe the internal work, so as to avoid danger.3, crusher with 3 lithium grease, or MoS2 grease, is added to the bearing cavity 1/3~1/2, 400H joined the crusher working physical grease, 2000H, open shaft bearing pairs for cleaning work 7200-10000 hours, should be replaced with new bearings. The bearing at the upper end of the spindle assembly is a movable end, and the lower end is a fixed end. When the assembly is made, the pulley shall be rotated by hand, and the rotation of the pulley shall be flexible.4, tension transmission V belt size should be adjusted appropriate to ensure that V with uniform force, dual motor drive, on both sides of V should be grouped matching, the length of each group as consistent as possible, should be adjusted to make the two motor current difference is less than 15A.
Before starting the sand machine, it is necessary to check the whirling chamber of the equipment, whether the door is closed or not, and prevent the material from rushing out of the vortex chamber to observe the danger. In the boot device, should pay attention to open order equipment sand production line, should first open the discharging device, then the sand making machine, finally open feeder, and sand making machine must start load until the sand making machine normal operation after the opening in the feeder, however the equipment shutdown sequence and the sequence is completely the opposite. In order to reduce wear sand making equipment, strict demands on the feed particles, prohibition is greater than a specified material into the sand making machine, otherwise, will cause the impeller imbalance and excessive wear, and even affect the normal operation of the sand making machine, when discharging equipment to stop operation, and should stop feeding. Otherwise, will damage the impeller and the motor burned.
This depends on the extent of your use, and did not buy how long, about a week to a big maintenance, work a day, a small check.
