PSMC Unité de Séparation Magnétique, Contrôlée par Ordinateur (PC)



Description Générale

The Computer Controlled Magnetic Separation Unit, "PSMC", has been designed to understand the operation of a magnetic rotary drum used to classify materials of different magnetic characteristics.

The main components of the unit are: a feed hopper with a vibrating trough, a non-magnetic rotary drum and a permanent magnet acting in an area of 180º of the rotary drum.

The process starts when the feed material (a mixture of components with different magnetic properties) is introduced in the hopper and the vibrating trough moves it to the inlet of the rotary drum. The trough is controlled by computer. The inlet flow to the drum is controlled by varying the frequency of the vibrating trough, the amplitude of the vibration and its distance from the hopper. When reaching the computer controlled drum, the non-magnetizable components are not affected by the permanent magnet and drop to the first tank. However, the magnetizable components adhere to the magnet and drop later on in the other tank, when they are out of the magnet magnetic field reach.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
