This product is the main product of the injection system and is intended for use in tunnels and mines, delivering materials through pipelines to the injection site. Applied for pumping fine-grained and viscous materials such as various concentrations of tail solutions, municipal precipitation, coal sludge and other materials through pipeline pumps. The viscosity of the solution is required to be at least 15 cm, the maximum size of a large filler is 5 mm, the solid particle content is from 50% to 85%, and the pH is from 6 to 9.5. Applicable to fine-grained materials such as tail solutions, dust masses, red mud, precipitation, coal sludge, etc. d.
