Product Details

This apparatus is designed to separate magnetizable components from a solid mixture, such as a sand and steel blend, demonstrating the industrial process of magnetic sorting used in coal and ore preparation. It allows students to study the principles of material separation based on magnetic properties and to analyze the efficiency of the process under different operating conditions. The unit consists of a feed hopper with a vibrating trough that conveys the material onto a rotating, non-magnetic drum. Inside the drum, a fixed permanent magnet attracts and holds magnetic particles as the drum turns, while non-magnetic particles fall off due to gravity. The rotation speed of the drum is adjustable via a potentiometer, and the feed rate can be controlled by modifying the hopper outlet distance and the vibration settings of the trough. Separated fractions are collected in different steel tanks for analysis. Its primary applications are in mineral processing and recycling education, where understanding material separation is crucial. The key benefit is the hands-on investigation of a key industrial technique, enabling students to optimize variables like feed rate and drum speed to achieve effective separation and gain practical insight into resource recovery and processing.
