20Kg/group,packed in a iron drum.
☆ Before curing：with good fluidity and strong filling ability,easy to operate,safety and environmental protection
☆ After curing：with low shrinking percentage and good adhesion,bearing capacity is high,can tear down
☆ Can cure at the low temperature of -5℃
☆ With high impact resistant ability,especially suitable for the lining plate filling of coarse broken gyration type crusher
BD66 crusher special wear resistant filling material product usage:
BD66 crusher filling material (backing adhesives) is used in the filling/supporting between crusher lining plate and substrates,gravel barrels and jacket clearance,support cone and protective layer space,at the same time it can be used as buffer material,when the equipment suffers impacting or load vibration from broken ore, also used in the structural reinforcement,impact resistant vibration of ball mill wear resistant lining plate and cylinder clearance.

BD66 crusher repair backing adhesives use technology:
1 Cleaning up and preparation: clean up the residual filling material on the surface of the cone, as well the grease dirt and smudge on the areas where touched with the adhesive,then fit up the cone and lining plate.Seal up the cone/lining plate fitting surface and annular ring with the adhesive tape etc,for fear of adhesive leakage,and protect the screw threads on the shafts if necessary,try to construct under the temperature of 5℃-30 ℃ during using.
2 Configure adhesive: Make the blender fix on low speed electric hand drill,Open the A component of BD66 crusher filling material,stir it for 1 minute,then pour the B component into the A component drum at the same time stir it with the electric blender,it's OK for color uniform,general stirring time is not more than 4 minutes.
Operation time: The total time from start mixing to finish filling is not more than 15 minutes(the data for 20℃)
3 Pouring: Make the mixed-up BD66 adhesive solution pour into it along the cone or a place of lining plate crack,easy to exhaust,in necessity,can make a cofferdam guide with plasticine etc,until overflow from the top of crack.Don’t pour into the adhesive without mixing uniformly(with different colors)
4 Curing: Place to cure for 12-24 hours,the temperature makes a big difference for the curing time,the curing speed is fast for high temperature,it can put into using to cure for 24 hours.
BD66 crusher filling material is the general chemicals,should pay attention to waterproof and preventing fire in the process of transportation and storage,stored in a cool and dry place,the storage period is 6 months.
