Other Details

These are used by most of the mineral manufacturers for getting total iron free material. Extra high power magnetic plate at the material outlet side can also be provided.

Models are available in any drum size as per the requirements. Size Range The permanent Drum Separators are available in standard drum diameters of 300mm,400mm and 450mm. Drum length ranges from 300mm to 1200mm. Other sizes can be made as per the requirements. The larger diameter and length of the drum the greater is the volume of material which can be handled. Permanent Magnetic Drum Separators “ALFA” Permanent Drum Type Magnetic Separator is the most useful non electric separator for separator for separating tramp iron from non magnetic material processed in bulk Quantity for the purity of end products, recovery of metals having commercial value and protection of processing industries for separation of iron contamination from minerals, chemicals, food, flour, plastic, grains, sand, cement, fertilizers, abrasives, glass slag, ores, rock and many other products.


Working Principle & Magnetic System The Permanent Magnetic Drum consists of a stationary permanent magnetic assembly having uniform and everlasting magnetic field across the entire width of the drum. Which is effective over approximately half the drum circumference.


Drum shell made of non magnetic stainless steel revolves around the magnetic field. As the material fed everilly from the chute falls over the drum, Powerful magnetic field attracts and holds ferrous particles to the revolving shell. As the revolving shell carries the iron particles through the stationary magnetic field the nonmagnetic material falls freely from the shell while ferrous particles are firmly held until carried beyond divider and out of the magnetic field. The strength of the permanent magnetic drum is guaranteed to be greater than the corresponding electromagnetic drum.


The Permanent Magnets used are everlasting magnets and their strength dose not diminish during normal use. Note: We reserve the right to make alteration in the machine from time to time as required.
