The finer the particles to be produced, the higher the energy that is needed for the production. That is why we at Hosokawa develop technologies allowing our customers to produce finer and finer particles at reduced energy consumption. The PULVIS, a combination of a vertical agitated ball mill and a high performance air classifier represents a further milestone on our way.
The PULVIS offers a compact, low-abrasion and low-energy fine grinding, even of hard materials such as ceramic raw materials or glass to less than 0.5 μm in the d50 and <2 μm in the d97.
Compared to wet grinding, the particle size distribution is much steeper with a sharply defined top cut. Energy savings compared to jet milling are up to 40 %..
