Wet magnetic drum separator structure and magnetic field characteristics
The structure of this magnetic separator is shown in Figure 1. It is composed of three main parts: Magnetic drum 1, magnetic system 2 and bottom tank 3.
The magnetic drum is made of rolled and welded stainless steel plate with thickness of 2 to 3 mm. The end cover of the magnetic drum is a cast aluminum piece, connected to the drum with stainless steel screws. The reason why use stainless steel (or copper) or aluminum for the drum is because these materials are non-conductive materials, with good permeability, so that the magnetic lines of force and the drum does not form a magnetic short circuit. The surface of the magnetic drum is also covered with a layer of wear-resistant rubber so that the drum surface is not worn. At the same time, it is conducive to the adhesion of magnetic particles on the drum surface, which strengthens the carrying effect of the drum on the magnetic particles, and the drum rotation is driven by the motor.
