The objective of this research is to model the behavior of a blend of prepared biomass and coal particles in a Raymond Bowl Mill and to evaluate the expected performance change of the mill classifier when implementing simple hardware modifications. There have been few studies where milling systems have been modeled.
The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.
A typical air classifier mill — called a verti-cal air classifier millbecause of its classifier wheel's ori-entation — is shown in Figure 1. The mill has a round vertical housing enclosing an internal classifier wheel, which has multiple closely spaced vanes (or blades), and an impact rotor that's mounted in a horizontal position and
