Permanent Magnetic Drum Separators And Drum Machines

SIZE RANGE

Permanent Drum Separators are available in standard drum diameters of 300, 400, 500, 650, 800, 1000.
• 300 to 400 mm diameter for small particle sizes low tonnage or volume capacity
• 500 to 900 mm diameter for mid-sized particles, medium tonnage or volumetric capacity, typically used in the Sponge Iron Industry
• 1000 to 1500 mm diameter for large particle size, high tonnage, typically used in the Slag Recycling Industry
Drum widths range from 300 mm to 2000 mm. Custom size of Drums can be made considering the requirement. The larger the diameter and width the greater is the volume of material which can be handled.

INTRODUCTION

MITOOL Permanent Magnetic Drum Separators are crucial in every processing industry therefore, they are widely in used for the separation of iron contamination from minerals, chemicals, food, flour, sugar, grains, plastics, sand, cement, fertilizers, rock, borings and many other gravity or conveyor transported products.

MAGNETIC MATERIALS

FERRITE CERAMIC MAGNETS: This LOW INTENSITY DRUM uses ceramic magnets. This is useful for most of the applications where either iron is in free form, or where the iron particles are large. The average magnetic field strength on the magnetic drum surface would be in the region of 1500-2500 Gauss depending on the drum size.

RARE EARTH MAGNETS: This MEDIUM INTENSITY DRUM uses a special grade of Neodymium — Iron- Boron (Rare Earth) Magnets. This is useful for removing weak magnetic contamination as well as fine iron particles. The average field strength on the drum surface would be in the region of 4000-5000 Gauss. The Rare Earth Magnetic Drum is obviously far more expensive than the Ceramic Magnetic Drum, but, it offers unmatched performance in certain difficult applications.

WORKING PRINCIPLE

MITOOL Permanent Magnetic Drum consists of a stationary Permanent Magnetic assembly around which the drum shell revolves. Permanent Magnet assembly has an uniform and long lasting magnetic field across the entire width. The magnetic field is effective over approximately half the drum circumference. It is necessary to bring it into position before starting. As material fed evenly reaches the drum, the powerful permanent non-electric magnetic field attracts and holds ferrous particles to the revolving shell. As the revolving shell carries the material through the stationary magnetic field, the non-magnetic material falls freely from the shell while ferrous particles are firmly held until carried beyond a divider and out of the magnetic field. The Permanent Magnet used is an everlasting magnet whose strength does not diminish with time during normal use and can be used through out the life of installation.
