Cyclone Separator Design, Components and How it Works - …

Cyclone Separator Wood Mill Setup. Another common application is the household vacuum cleaner. An electric motor drives a fan which draws air and particles into the vacuum cleaner body. There are few parts to maintain and the vacuum has the added advantage of having no bags that need to be replaced.

Best energy consumption

The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill circulating loads of >1000 per cent. Manufacturers have countered this generally satisfactorily with pressure drops reduced by lower nozzle ring velocities and the addition of ...
