epoxy ceramic adhesives used in mining use cyclone powder selector pipeline rubber lining repairing and protecting
One company's closed-circuit grinding system consists of three 3.5 m x 10 m diameter central discharge drying raw mill and 4m diameter
cyclone powder concentrator matching.The powder choosing chamber of this powder concentrator and 6 cyclone cylinder spiral inner shell
part uses the cast stone lining plate,due to long-term exposure to the high concentrations of dust gas scouring,the abrasion is serious.
So in December 2005,make the cast stone lining change into the abrasion resistant ceramic lining,detailed introduction as follow:
1. As a result of the straight cylinder upper part and spiral section lining is basic in good condition,so we can only change the straight bottom and
throat part lining.
2.Knock out the remaining lining plate of the above part,clean up the inner shell.
3.Use 5mm thickness abrasion resistant ceramic chip to instead of the cast stone lining plate.
4. Choosing Xiangyang City Hundred Shield Coating Material Co.,Ltd produced BD151 anti abrasion wearing resistant repair epoxy compound
ceramic adhesives to connect bonding as the abrasion resistant ceramic tile and inner shell.(details from http://www.wearcoating.com/abrasion%20resistant%20ceramic%20adhesive/anti_wearing_ceramic_tile_epoxy_compound_repair_adhesive_4527.html).
First of all,do the polishing,sand blasting and roughening treatment on the bonding surface during using,in order to improving the bonding strength.
Then wipe the bonding surface with solvent such as acetone or ethyl acetate etc,and dry it by airing for about 10 minutes,make the bonding surface be
dry and clean.
According to the specified ratio,make the two components of the adhesives mix uniformly,then smear it on the bonding surface,on the premise of
ensuring no shortage of adhesives,the coatings are the thinner the better,had better smear the double-sided adhesives.Make the ceramic tile after
smearing the adhesives be folded and compacted with the barrel.It can be put into using after the adhesives curing for 24 hours.
Improved powder concentrator has been used for nearly 3 years so far,without appearing the phenomenon of ceramic tile falling off.It is solid and
reliable during using,accord with the production requirements.Each using adhesive quantity is 20kg,the weight of ceramic chip is 350kg,the value of
ceramic tile is about 9000 yuan,according to the operation time for five years.Is equivalent to 1800 yuan a year,and the weight of 25mm thick cast stone
lining plate based on the same area is 1500kg,the value is about 10000 yuan, the service life based on the usual sporadic replacement is about 1 year.
So just calculate the material costs,it could save 8200 yuan each year.
