Whim Magnetic Separators. Wet high intensity, high gradient WHIM separators are used for the continuous extraction and concentration of fine paramagnetics (less magnetic material) presented in a wet state. They are used when a material cannot be separated in a dry state. WHIM units can be designed as single, double, 4-station or 8-station units.

High-gradient magnetic separation in a strong field is essentially a periodic process. In canister constructions it consists of separate operations, introduced by the electronic processor, while in rotary constructions the process is continuous. The separators with high capacity are very bulky, heavy and have massive rotors. All this reduces their technical and economic viability.
