Description
The Oreflow Australia (OF-CBEM & OF-CBM) range of self-cleaning magnets can be used in a range of applications removing ferromagnetic material from all sorts of of ore. The magnets are capable of lifting from 0.1kg to 35kg from a burden depth of 80-450mm thick. The operating principle is based on a deep-reaching magnetic field using either permanent magnets or electromagnetic coils. An overhead suspension magnet is arranged above a feeding conveyor belt and extracts the ferromagnetic materials from the supply flow against the force of gravity. Self-cleaning magnetic separators have a circulating conveyor belt equipped with projections which removes the ferrous parts attracted by the magnets and allows them to fall into a separate container.
Overhead suspension magnets can be arranged either laterally above or even along the supply flow. Longitudinal arrangement above the container in the supply direction is advisable for the best separating result, since here the material is loosened and available in free flow. An overhead suspension magnet positioned laterally to the supply flow requires a larger magnetic force to achieve the same sorting result due to the greater distance and the material’s rest position. In this respect, the advantage of this arrangement is its lower space requirement.
Overhead suspension magnets with a manual removal device can be used where there is a low mass proportion of coarse or ferrous parts. Self-cleaning overhead suspension magnets in contrast ensure efficient processes where there is an increased iron proportion in the supply flow.
Overhead and manual overhead suspension magnets are available according to size, application area and ambient conditions as a dry installation with active or passive air cooling or with active or passive oil cooling.
