Abstract:

Aiming at the problems of uneven slurry preparation，long time of disassembly and mainte⁃

nance，GSJ-100 high-speed mixer，with fast wear and short service life of the existing filling slurry mixing

equipment，for tailings filling material was developed. The double-layer 8 stirring rods were arranged in the

inner cavity of the mixing equipment to fully shear and collide the filling slurry，and the obtained filling slur⁃

ry had high concentration and good uniformity. The cylindrical casing is sealed on both sides of the end cov⁃

er，which realizes the maintenance and overhaul on the production line without dismantling the machine，

and improves the production efficiency. The wear-resistant design of the easy-to-wear parts such as mixing

rods and rotor parts has greatly improved the service life of the equipment; the contact parts of each compo⁃

nent are sealed to ensure that the equipment does not leak slurry during operation and the sealing effect is

good. The industrial test results show that the strength，fluidity and uniformity of the filling slurry or test

block prepared by the mixing equipment can meet the filling design index well，and have a wide application

prospect.
