Energy use pattern in rice milling industries—a critical

Jun 07, 2012While the energy consumption in modern rice mills generally vary from 18–26 kWh/t for raw and 20–30 kWh/t for parboiled paddy, sheller and huller mills required higher energy. Rice mills having elevators for material handling consumed 7–10 kWh/t and 24–25 kWh/t of mechanical energy for parboiling and drying, respectively.

Magnetic Separation Technology Can Improve Grinding

There, the effect of a trunnion magnet system on the ball mill was significant: Total mill feed remained essentially unchanged, averaging approximately 1,300 t/h; however, total mill power consumption dropped 8% from an average of 7,600 kW to 7,000 kW. The mill work index dropped 10% from an average of 5.5 kW-hr/T to 5 kW

Vertimill

Vertimill has an excellent turndown ratio and can be operated at lower than installed power with less effect on grind efficiency than for example horizontal ball mills. Feed Flow-Rate. This parameter is used in conjunction with the feed density and motor power to establish the grinding rate in kWh/mt.
