Hopper magnet TM 250 N

Magnetic separator for the hoppers of injection moulding machines s designed to separate iron tramp from free-flowing dry materials (such as regranulates, crushed plastic materials, plastic crumb, rejected mouldings etc.). The hopper magnet protects the moulding machines (with standard cone hoppers) and other processing equipment from damage by ferromagnetic particles.

How does hoppoer magnet work?

While the bulk powder material falls through the magnetic tubes, a very strong magnetic field (generated by neodymium NdFeB magnets situated inside of the tubes) traps all metallic particles on the surface of the grids. Thanks to the neo magnets the magnetic impurities captured on the tubes are not carried away by the stream of the continually poured material (what happens if separators are fitted with weaker black ferrite magnets).

How is hopper magnet cleaned?

The basic elements the magnetic grate consists of are telescopic magnetic tubes (made from stainless steel). Cleaning is very easy and rapid thanks to the telescopic tubes. During the cleaning the magnetic cores are manually withdrawn from the stainless tubes and the ferrous particles fall off the stainless tubes. In contrast to the non-extendable magnetic grates (that are to be cleaned by hand in a laborious way).

Advantages of hopper magnet

Our hopper magnets are not only very effective, but also easy to clean, install and transport (from one application place to another), practically maintenance-free and inexpensive to acquire and operate.

What pipeline is the separtor connected to?

Magnetic separator for plastic extrudes & injection moulding machines is standardly manufactured in diameters from 100 to 400 mm, but we can adjust its design as well as the size to client's requirements.

TM - basic version

Is designed to separate iron tramp from free-flowing dry materials (such as regranulates, crushed plastic materials, plastic crumb, rejected mouldings etc.).

TM FL - version with a round flange

The flanged version has two significant advantages. The material flow is directed to the center of the separator, i. e., to the magnetic tubes. The round flange matches the round shape of the hopper and that is why it prevents any unwanted leakage of the contaminated material alongside the separator edges.

TM FL - version with a flange and a cleaning device

The variant with the flange and the cleaning device arranges, simultaneously and at a very low surcharge, for a more comfortable cleaning way as well as for an appropriate storage place of the separator.

TM EKO - version with closed cores

Magnetic separator TM-EKO for the hoppers of injection moulding machines is designed to separate ferromagnetic particles from free-flowing dry materials. The basic elements the magnetic grate consists of are polished magnetic tubes (made from stainless steel). While the bulk powder material falls through the magnetic tubes, a very strong magnetic field captures all ferrous particles on the surface of the grids. As there is no easy cleaning system at the EKO version, the captured Fe particles are removed manually from the surface of the magnetic tubes. On the other hand, the combination of the extremely strong magnets (N52) with only one layer of the very thin protective stainless steel cover arranges for an extremely high magnetic induction on the surface of this separator (about 12000 G).
