Electrostatic Precipitators

5 Drift speed The particle drift speed (we) results from a balance between the electrostatic force due to the charge (Fe) and the resisting drag force (Fd) exerted by the air due the relative motion between air and particle. For the drag force, we assume that the particles are very small.

Recent Investigations in Electrostatic Separation - AusIMM

The beach sand industry is the only Australian mineral industry which, so far, has used electrostatic separation on a full commercial scale. The main application of the process is for the separation of rutile from zircon. Laboratory work has demonstrated that electrostatic methods are effective for ilmenite-monazite and cassiterite-zircon separations, thus facilitating the production of...

Electrostatic separator - Wikipedia

An electrostatic separator is a device for separating particles by mass in a low energy charged beam.. An example is the electrostatic precipitator used in coal-fired power plants to treat exhaust gas, removing small particles that cause air pollution.. Electrostatic separation is a process that uses electrostatic charges to separate crushed particles of material.
