KBT-6 Roller Grading Sieve mainly consists of Electric Motor, Decreasing Machine, Roller Device, Machine Frame, Sealing Cover, Feed-in & Discharging Material Mouth. Roller Device is installed on Machine Frame aslant, Electric Motor is joined with Roller by coupling, and Driving Roller Device turns around its axes. When material comes into Roller, due to Roller's slanting and turning, the material on sieve surface is made to roll and overturn, making qualified material come out through the sieve net of Roller outer edge and unqualified material out through the sieve net of Roller end.
KBT-6 Main characteristics of Roller Grading Sieve: (1) Sieve holes are not easy to be jammed. (2) Stable operation, less noise. (3) Simple structure, easy to maintain. (4) Sieving Tube can be closed, easy for sealing and dust collection. (5) The entire machine is of high reliability, less once-for-all investment. (6) It adopts special sieve net, high efficiency in sieving, and shelf period is long.
