Iron Ore Magnetic Processing Plants
SBM has produced several thousand low intensity magnetic separators both dry and wet versions to the iron ore industry. SBM has developed and designed the low intensity magnetic separators to meet the highest demands for capacity, metallurgical performance and mechanical availability. Iron ore magnetic processing plants will help the customers make high profits.
Iron ore magnetic separator
SBM low intensity magnetic separators are designed to recover magnetic material from nonmagnetic matter. The separators are of modular design with several frames and process tank designs using a common magnetic drum for ease of selection of the best machine for each individual application. The magnetic system is using permanent magnetic material to achieve the highest magnetic attraction force with maximum efficiency.
The magnetic separation of iron ore and other magnetic minerals is a complex process. During the separation process, each particle is subjected to a number of forces including gravity, drag, etc. The simplified equation below describes the magnetic force the particles are subjected to. While the capacity of iron ore magnetic processing plant is very much dependant on the material to be processed, the iron ore magnetic processing plants have proven to have outstandingly high capacity thus fewer machines are required. The separators are available in several sizes and designs to suit each individual application.
The machine is designed to allow normal variations in feed conditions without the need of any adjustment. Parameter adjustments, sometimes required at time of commissioning, are made easy by the design of the machines. The iron ore magnetic processing plants are protected against wear by rubber linings of the tanks and rubber or steel covering of the drums. Bearings are designed for extremely long duty and the lubrication can easily be automated. The availability of the SBM iron ore magnetic separator has proven to be excellent from many years in service.
Finer iron ore material is in almost all applications preferred to be processed in a water. Also for the wet processing there are a number of models to choose from to suit the various requirements. The models are mostly selected for processing of ore at the feed end of the concentration circuit.
For production of the final concentrate the counter-current, the magnetic processing machine model is the most efficient and mostly used model for producing high grade products. For recovery of e.g. magnetite and ferro-silicon in dense media separation processes a special model which is designed to provide highest possible recovery of the media. For all iron ore magnetic processing plants are selected to achieve best performance in each individual case.
