Have you ever paid attention to the wear of the impact rotor? Have you considered what went wrong after the wear? Need alloy hammer head to buy from us! Vertical impact crusher, also known as sand maker, is widely used in building sand processing, cement preparation and fine grinding of raw ore in metal mines. As the executive part of the vertical shaft impact crusher, the service life of the worn parts of the rotor directly determines the maintenance cycle of the vertical shaft impact crusher and the startup rate of the equipment.

1. Normal wear and tear. The wear part of the throwing surface presents a central symmetric circular arc-shaped wear depression. When the residual amount of wear-resistant ｉｎｓｅｒｔ is less than 3mm after wear, it should be replaced in time.

2. Unilateral wear. The throwing surface presents a middle arc-shaped wear depression, and the wear part is on the upper or lower side. When the residual amount of wear-resistant ｉｎｓｅｒｔ is less than 3mm, it should be replaced in time. At the same time, it is necessary to adjust the angle of the guide plate and the thickness of the accumulated material in the crushing cavity to completely solve the lateral wear.

3. The throwing head is cracked or broken. ｒｅｐｌａｃｅ the cracked or broken throwing head in time, and check whether there is iron clamping, excessive feeding force or no sand inclusion on the assembly surface, etc., and adjust and clean it in time to avoid similar situations.

4. When the matching throwing head on the rotor is worn to the replacement standard, the rotor throwing head assembly must be replaced. Can't selectively ｒｅｐｌａｃｅ one piece, otherwise it will affect the rotor dynamic balance.
