One of the simpler and cheaper dust collectors, this equipment has low efficiency except when used with coarse dust. Gas with entrained dust enters tangentially at 50–100 ft/sec and flows downward in a helical path in an annulus, then upward in...

Cyclonic separation is a method of removing particulates from an air (or gas) stream, without the use of filters, through vortex separation. Rotational effects and gravity are used to separate mixtures of solids and fluids. A high speed rotating...
