Abstract
An apparatus for separating a stream of particles comprises a charging device for injecting a net charge into a plurality of particles and a collector adjacent the charging device. The collector is grounded and arranged so that the charged particles disperse and collect on the collector according to a characteristic of the particle, such as size. A method of separating a stream of particles is also disclosed.
Claims20
An apparatus for separating a stream of particles by size, comprising:
- a) a charging device for injecting a net charge into a plurality of particles;
- and
- b) a collector adjacent the charging device, the collector being grounded and arranged so that the charged particles disperse and collect on the collector according to size.
A method of separating a stream of particles by size, comprising:
- a) injecting a net charge to a plurality of particles including particles having different sizes so that each particle has a charge to mass ratio depending upon the size of the particle;
- and
- b) allowing the charged particles to disperse and collect on a collector having a conductive surface.
