The permanent Magnetic Drum consists of stationery permanent Magnetic assembly having uniform and everlasting Magnetic field across the entire width of the drum, which is effective over approximately half the drum circumferences as shown in fig. Drum shell made of non-magnetic stainless steel revolves around the magnetic field. As material fell evenly from the chute falls over the drum, powerful magnetic, field attract & holds ferrous particles on revolving shell. As the revolving shell carries the iron particles through the stationery magnetic field, the non-magnetic material falls freely from the shell while ferrous particles are firmly held until carried beyond divider and out of magnetic field.
The strength of the permanent magnetic drum is guaranteed to be greater than corresponding electromagnetic Drum. The permanent magnets used are everlasting magnets and its strength does not diminish during normal use and can be used through out the life.
We are market leader in fabrication of indigenous high intensity, high gradient dry permanent magnetic roll separators in the Indian market. These machines are manufactured based on the advanced permanent roll technology, which has been used successfully in hundreds of industrial minerals applications around the world. We use high-energy rare earth neodymium permanent magnets assembled in a proprietary configuration to generate forces of magnetic attraction, which can be used for processing any material from ferromagnetic to weakly paramagnetic.
A short special fabric conveyor belt covers the magnetic roll and a tensioning idle roll driven by a motor. A feeder discharges material on the belt on continues controlled rate of flow at uniform layer thickness. The ferromagnetic and paramagnetic particles adhere to the belt while the non-magnetic particles flow freely off the end of the conveyor. The division of paramagnetic and non-magnetic adjusted by using a splitter plate located below the belt. It can be configured stacked in any number of passes to suit the user requirement.

We manufacture and supply screen separator, a unique particle size gradable separator designed for greater capacity per meter square of screening area & over size material discharge with relatively much less percentage fines than other screening machines.
The top weight on the motor shaft rotates in a plane close to the center of the mass of assembly. Rotation of the top eccentric weight creates vibration in the horizontal plane that causes material to move across the screen cloth to periphery. Increasing the top eccentric mass increases the horizontal throw, causing oversize material to discharge at a faster rate.
The bottom eccentric weight rotates below the center of mass, creating tilt on the screen, giving vibration in vertical & tangential planes. Increasing the vertical component of motion, which promotes turn over of material on the screen surface helping maximum quantity of under-size material to pass through the screen. The vertical motion minimizes blinding of screen by “near size” particles.
The tangential component of motion is controlled by the angle of lead given to bottom weights with relation to top weight. Variation in lead angle controlled the spiral pattern of material travel over the screen cloth can be set by the operator for maximum throughout & screening efficiency for any screen able product be it wet or dry, coarse or fine, heavy or light, hot or cold. Typical material passes rapidly through the screen during its travel to the periphery. The over size material get continuously discharged through a tangential outlet.
Standard sizes are available in 24” 36” and 48” diametre custom sizes can also be made on request.
