TowerMill is a vertical agitated media mill developed in Japan in the 1950s. Until now, TowerMills have been used in ferrous and non-ferrous mines for processes of ore grinding, flue gas desulfurization (FGD), limestone grinding for neutralization and further in other industries such as environmental fields all over the world, for the advantageous capability of high capacity and fine grinding. In particular, TowerMills are adopted for replacing conventional horizontal ball mills or for fine grinding after coarse grinding by ball mills.
Major processes
- Feed size: max. 40mm
- Product size: from microns down to sub-microns
- Standard mill size range from 0.4kW up to 1120kW
- Energy saving due to highly effective grinding
- Space saving and suitable for retrofitting
- Low noise level and small vibration
- Continuous and high capacity grinding
- Maitenance-free mill body due to its unique shell grid liner mechanism (material lining)
- Simple grinding mechanism, solid structure
EIRICH TowerMill effectively agitates the grinding media filled in mill shell with screw
equipped
with double helical flights. By the impact and abrasion effect the material is ground in mill
shell.
Mill screw with double helical flights is hung in the cylindrical shell (Mill shell
assembly) and it is rotated by the driving device (Main drive motor) installed at the
top
of TowerMill via the reduction mechanical device (Gear Reducer).
TowerMill grinds the material in the slurry by impact/abrasion motion of grinding media. Mill
body
is made of normal steel and the internal surface is rubber lined for corrosion-resistance. For
abrasion resistance, screw double helical flights are equipped with replaceable liners and mill
body internal surface is equipped with shell grid liners that enables to form a layer of
material
(grinding media and grinding material) lining.
