Used as head pulley in belt conveyors for continuous automatic removal of ferrous from non-ferrous material. Eriez new axial-interpole circuit provides very high ferrous recovery.
Permanent Magnetic Pulleys
Often used to convert a belt conveyor into a powerful magnetic separator.

The Very Low Iron Metal Separator (R-INOX) has a drum of high remanence with highly powerful magnets that can separate iron metal from light iron metal (similar to stainless steel) and from the inert.
The Very Low Iron Metal Separator (R-INOX)is built with a hard metallic structure. It supports two drums and the belt conveyor, which passes over a stainless steel table to have a totally plane surface. This belt is always centered by an automatic centering system.
Outgoing drum is a magnetic drum. This drum is made of Neodimium's high powerfull magnets, assembled into studied configuration, giving a very strong magnetic field. This allows to separate very low iron material from others. It also will separate small iron metals that they were not able to be separated by other equipments.

The Permanent Magnetic Roller (R-RM) has a cylindrical body containing powerful magnets, ferrit or rare hearth (Ne-Fe-B), making it a high intensity magnetic separator. There is no energetic cost.
Magnetic Roller (R-RM) are used installed instead of conveyor head Roller or after a vibrating feeder. It is able to carry the conveyor on. REGULATOR – CETRISA is able to manufacture any Roller in order to replace the existing Roller, so customer has no any dimensional change.
Sometimes, when a very high power or very big diameter is needed, REGULATOR – CETRISA is able to make and supply an Electromagnetic Roller (R-RME). It needs an electrical power supply for generate the magnetic field.
The magnetic separator operates with the material being fed onto a conveyor or directly through a vibrating feeder. Non-magnetic material is discharged forward of the Roller in the normal trajectory, but the magnetic elements are held to the belt and are discharged down the bottom side of the conveyor, outside of the magnetic Roller influence.

Magnetic drum TM model.
The magnetic drum TM substitutes the drive drum of the conveyor belt, separating ferric metals from any other inert , loose product. When it reaches the end of the belt, the material conveyed falls but the ferric metals are retainded by the drum, falling in a different direction to the purified material.

When material passes over the pulley, ferrous metal objects are attracted by the magnetic field and held tightly as the belt travels around the pulley are not released until they leave the influence of the magnet. Non-magnetic materials follow a normal trajectory. A divider plate can be installed to ensure that no remixing occurs. Standard diameters range from 6" to 36," and standard widths range from 10" to 62." Shaft size depends on length and weight

STEINERT Magnetic Head Pulleys attract tramp iron from these bulk materials in the same space as the normal conveyor belt head pulley. This avoids extensive reconstruction of your plant. Magnetic Head Pulleys protect your valuable processing equipment from damage by tramp iron that drum or suspension magnets miss buried in the burden.
STEINERT Magnetic pulleys are usually operated after the extraction of larger iron parts by other magnetic separators. Magnetic pulleys with strong neodymium type magnets can reclaim small, low magnetic particles - partially stainless - from the bulk materials.

MAGNETIC SELF-UNLOADING SEPARATORS
They are intended to extract and to remove automatically ferromagnetic impurities and things from free-flowing bulk materials that carried by a conveyer belt from 650 to 2000 mm wide.
Extracted ferromagnetic things are disposed by conveyer belt into a storage.

Cascade magnet systems are used in situations where ferrous particles have to be removed thoroughly from large quantities of raw materials. Cascade systems are available in manual and automatic models and are strongly built with a 4 mm thick stainless steel or steel housing. Bakker Magnetics cascade systems have a wide range of uses and are easy to incorporate in existing systems. A valve box is built in to the cascade systems to remove the ferrous particles that have been collected. Once the valve box has been opened, the magnets can be turned away and the ferrous particles will then drop out of the system via the side exit. Both manual and pneumatic versions are available in all models. With the pneumatic versions, a push of a button is sufficient to remove all the ferrous particles collected in the valve box chamber. Optionally, this type can be supplied with an electrically operated valve. All the components of the pneumatic system conform to the ISO and CETOP standards. As an option, the automatic versions can be fitted with a pressure tank which enables the system to stay in service when the supply of air pressure is lost. If required, all models can be fitted with inspection windows and/or manganese steel wear plates.

One main application for the High Gradient Magnetic Separator HGS is the processing of minerals such as heavy mineral sands, glass sand, ceramic raw materials, salt, slag, fine coal and other fine ores that contain feebly or paramagnetic particles that need to be separated. Leading edge technology is required to meet these duties of separation for either the removal of impurities or the recovery of valuable minerals. The Steinert HGS provides the performance for these critical separation applications, the high magnetic field gradient and the reliable design. The HGS is a high intensity magnetic separator with a modular design consisting of either single or multiple stages to suit the separation of the material.
Each stage or module consists of a short belt conveyor to transport the material continuously to the magnetic pulley of the HGS which generates a high magnetic field gradient and a magnetic field strengths of up to 20,000 Gauss. The open design of the Steinert HGS allows the processing of particles from 10 mm to less than 1 mm in size.

Bunting Magnetic Separation Pulleys are engineered for easy installation in belt conveyors. They feature a radial magnetic field that gives complete magnetic protection over the entire face of the pulley for superior removal of ferrous contaminants.
Separation Pulleys can replace existing pulleys at the discharge end of a conveyor line and be used alone or in combination with other Bunting Separators designed for conveyor applications like our Suspended Plate Magnets and Cross-Belt Separators.
o Continuously remove and discharge tramp metal from material flow.
o Radial magnetic design eliminates dead spots.
o Order standard high-density Ceramic or optional Rare Earth magnets.
o Sizes to fit your conveyor with removable or fixed shafts.
o Select 6", 8", 10", 12", 18",or 24" diameters.
o Specify widths in 2" increments.
o Enjoy maintenance-free operation.

General description
Coolant, containing ferritic perticles, is pumped into the magnetic separator where the coolant is then passed over rotating magnetic rollers. The ferritic particles then attach themselves to the rollers. As they accumulate the particles are eventually srapped off rollers and residuals coolant is allowed to drain back into the filter system. Drained particles are deposited into an optional sludge container.
