Conveying technology for the cement industry Every transportation scenario offers new challenges: sometimes it involves moving coarse-grained material through rugged terrain from the quarry to the factory grounds, or hot materials from a kiln cooling system to a silo.
And the truth lies in knowing what rubber cement is and what role it plays in conveyor splicing. Rubber cement that is used in belt splicing usually consists of 10-20% rubber compound dissolved in 80-90% solvent. When the volatile solvent evaporates or as is sometimes said, "flashes off", all that is left is the rubber compound.
