it contains no moving parts. With adequate mill grinding capacity, the MPS mill equipped with SLK static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or higher <200 mesh, while the SLS dynamic classifier produces coal fineness levels of <100 mesh and 95% <200 mesh, or better. NEW MPS MILL ...

Gao et al. [5] established a dynamic model for a medium speed coal mill based on mass and energy balance and predicted the dynamic performance of a coal mill. Wang et al. [6] developed an approach ...
pressure regardless of the type of medium-speed, vertical spindle pulverizers you use. In our experience the spring frame of an MPS mill tuned for maximum true capacity will be set at about 20 tons minimum force on the grinding tires. A bowl mill spring or hydraulic preload for this size of mill will also be about 20 tons of pressure.
The operating principle of an MPS medium-speed coal mill is shown in Fig. 1. The raw coal enters the grinding parts from the coal chute. Raw coal is crushed into …
