Mechanical fine-grinding mill suitable for grinding of green tea

Hosokawa Micron has announced the development of a high-performance cooling type mechanical mill, the Micron Glacis GC fine-grinding mill. Suitable for fine grinding of heat-sensitive products, the Micron Glacis GC is suitable for the high-volume grinding of green tea.

The fine grinding and low heat generation of the Micron Glacis GC produces a tea with a better taste and flavour. The Glacis is able to achieve a high cooling efficiency (7.5 times more than the conventional mechanical mill) by running coolants through the outer liner and grinding rotor. The Glacis can ultra-fine grind low-melting point, heat-sensitive materials that we impossible with conventional units.

The Micron Glacis GC offers the particle grinding size accuracy of a jet mill (10-20µm) but with a higher-volume capacity and 50 per cent lower energy consumption.

Material is ground by strong impact and shear force generated at the space between the grinding rotor and the liner. Both the grinding rotor and the mill lining are specially designed with an effective cooling structure, which, alongside the reduced air volume required by the unit for cooling actively, prevents product oxidation and therefore deterioration of tea quality.

The Glacis has a low air volume requirement relative to grinding power, which means the additional auxiliary equipment such as the blower and bag filer can be scaled down, allowing for a compact installation.
