Impact resistant abrasion resistant coating repairs the ball mill roller bumps:
In the running process of ball mill,the rupture and falling off of the scaleboard will cause the steel ball impact abrasion mill cylinder,small problem is swell,large problem is perforation.We found there were many roller body swell phenomenons on the Daye coloured Fengshan copper mine ball mill during maintenance,changing the new roller body will spend too much time and high cost,the outage loss is also large.Can not install a new scaleboard directly as the roller body is not smooth.Use the BD708 impact resistant wear resistant coating of Xiangyang City Hundred Shield Coating Material Co.,Ltd to fill the leveling to install the new scaleboard,saving labour,time and cost.This machine uses 40Kg materials,finish the work of filling the leveling for one night, After installing the lining plate,the equipment has been normal operation for 3 months.
Specific maintenance steps as follows:
1. Polishing,cleaning,drying the substrate surface;
2. Brush coating the BD708 special undercoat.
3. After the undercoat curing,blade coating the BD708 anti shock abrasion resistance resistant coating and leveling;
4. Bake for 3 hours with iodine tungsten lamp to complete the repair.
BD708 impact resistant wear resistance coating has certain elasticity,can withstand and slow down the impact force of the steel ball to the liner plate and cylinder body,and has a certain ability to reduce noise.When install lining plate for a new ball mill,fill up a layer of BD708 impact resistant coating can effectively avoid or reduce the broken of lining plate,and can effectively reduce the noise pollution.
