Permanent magnetic separating rollers are tried and tested, high-performance, continuously operating separating systems and are intended for the automatic separation of ferromagnetic parts from small-grained or dusty material, e.g. grain, plastic granulates, wood chips, blasting sand for jet blasters, etc.; for the protection of the machines, grinding and processing plants used, for the avoidance of operating faults or for the recovery of the steel shot content from the blasting sand to be separated.

Inside the roller there is a fixed special magnetic system, which is firmly connected to the shaft journal opposite the drive. This shaft journal must be fixed in the laterally attached locking bearing by means of a screw. By rotating the shaft journal, the magnetic system inside the separating roller can be swivelled. The magn. zone extends over 200 degrees. The remaining part is the magnetic null zone. By pivoting the magnetic system accordingly, the desired drop point can be set in each case. The fixed perm.-magn. special system whose force field pierces the roller shell catches the magnetisable iron parts to be separated above the roller shell and pulls them to the rotating roller shell. This diverts the Fe-parts from the material flow and transports them to the set drop point, where the Fe-parts fall into the container provided at the beginning of the zero zone.

The special advantage of these continuous magnetic separating rollers is that they work reliably and with great safety with practically no loss of performance. They are easy to install in bulk materials with a small footprint and require no special operating or maintenance costs.

The separating roller is used for the automatic separation of ferrous particles from the non-magnetic material of the medium (blasting medium). The medium is to be fed consistently into the separating roller by means of customer-provided conveying equipment. The integrated magnetic roller separates the magnetic ferrous particles from the mixture. The magnetic roller of the separating roller is powered by a geared motor. The more loosened the medium supplied to the separating roller, the better the two fractions can be separated from one another. With encapsulated or adhering particles, the ratio of ferrous mass to the total mass has a major influence on whether the entire clump is separated to the ferrous area or is separated to the non-ferrous area.

The medium passes through the separating roller from top to bottom. In the event of an overflow of the medium over the magnetic roller, the ferrous share is separated from the product flow. The separated material at the outlet of the separating roller is advanced through two separate chutes (Fe / non-Fe) to the customer-provided transport equipment for further transport. Care must be taken here that the downstream transportation equipment does not create a backup at the separating roller.

When operating the separating roller with dust-forming or dust-creating media, the operator of the separating roller must take appropriate measures to prevent dust explosions. The formation of sparks due to static discharge, induction or when two metal parts strike against one another in the area of the separating roller cannot be entirely ruled out.

The machine is not suitable for operation in EX areas.
