Adopting analysis methods of aerodynamics in aviation on the basis of leading technologies, SLC, combined powder separator with the features of coarse powder separation, horizontal vortex separation and fine powder separation in one means, has been designed and developed by our company. It will greatly improve the output of mill by simple configuration and low cost. The internal mechanism is reasonable with high selection efficiency and good saving effect. It possesses the advantage of treating high dust content gas. This system with the feature of road and gas path united in one is much simpler, especially in the dry grinding system and air - swept mill system. In the course of cement production, it is mainly used as the primary classification equipment in the closed-circuit grinding systems, dry grinding systems, air - swept mill system.
