Magnetic Separation- Engineering Lab Training Systems.
Technical Description
During sorting, a solid compound is separated according to its material characteristics.
Magnetic
separation is a method of sorting which utilises the magnetisability of
components of a solid compound. Magnetic separators are often used in
coal and ore preparation.
In the , the solid compound to be
separated is charged into the feed hopper. A vibrating trough conveys
the compound onto a rotating, non-magnetic drum. Its speed can be
adjusted by way of a potentiometer. In one area of the drum there is a
fixed permanent magnet. Non-magnetisable components drop into a
collector tank due to gravity. Magnetisable components adhere to the
drum in the area of the magnet, are carried along and drop into a
different tank as soon as they are beyond the magnetic zone. An
adjustable separating panel can also be used to influence the purity of
the separated fractions. By rotating the permanent magnet it is also
possible to alter the range of influence of the magnetic field. The mass
flow of the feed material can be adjusted by way of the distance of the
hopper outlet from the vibrating trough and by the throw and frequency
of the trough. A mixture of sand and small steel items, such as hexagon
nuts, is recommended for use as the feed material.
The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
