LIMS dense media magnetic separators - 2

Magnetic separators for dense media recovery Metso has produced magnetic separators for dense media recovery since the mid-1960’s. Several hundred separators have been supplied since then for various operations on all continents. Although praised for their high efficiency from the outset, the separators have over the years become even more effective with higher capacity ratings. Designs and sizes The wet magnetic separators for dense media recovery are available in several sizes and designs to meet varying requirements from 2 Magnetic separators the processing industry. This co peration o...

by gradient, also called the magnetic force index, varies between different designs and is a factor when selecting the most suitable magnetic system for a particular job. As in all applications, the magnetic force is competing with other forces like gravity and hydraulic drag; the feed volume must be balanced to a suitable level, the magnetic force for a given separator being non-adjustable. Generally speaking, finer particles call for lower flow capacity of the equipment. By selecting a higher magnetic field strength (magnetic flux) and higher gradient the capacity can be increased...

Adjustment of magnet and drum position The position of magnetic drum and the angle of the magnetic assembly can easily be adjusted to obtain the best process performance. The adjustment possibilities include • Magnet assembly positioning in relation to the concentrate discharge weir • Horizontal position of the drum • Vertical position of the drum Feed Boxes The system for primary distribution of the pulp to the feed boxes supplied with separators is normally not part of the supply. However, Metso can optionally supply or advise on solutions for such systems. All feed boxes are normally...

Drum drive system The drum of a Metso magnetic separator has a drive shaft, which can be adapted to any type of drive. The position of the drive components is favourable, located outside of the tank away from pulp splashes and water. Experience shows that the drum speed is very seldom altered and Metso has delivered most its separators with direct drive gear boxes. This system has proven to be safe, efficient, clean and quiet and requires very little maintenance. The older system with an integrated V-belt drive is also available and is recommended for users who want maintain the possibility...

Application guidelines Absolute guidelines for model selection and dimensions are not available due to the widely varying nature of the media. Hence the data in the table below are only indicative. When in doubt of the properties of a specific ore use the lower part of the feed rates. Testing in laboratory, followed by on site testing is sometimes advisable especially when planning for larger installations. Application Type of Typical feed rate, Typical slurry feed media dry basis, g/l rate, m³ per hour per meter of drum width Dense media Magnetite 110 - 135 More than 25 recovery 135 - 175...
