RTSM-BJP series patented design sand mill, using the industry's first dispersion grinding integration technology, effective grinding area is large, the number of effective impact, material running track in order, the new design of permanent magnetic motor to powerful kinetic energy, improve grinding efficiency while reducing energy consumption. The excellent design makes the material flowing process, eliminates blocking pipes or precipitation, with self-cleaning filter to ensure ultra-long running time without blocking material! (Currently known to run continuously for 8 months without screen cleaning)
