The automatically cleanable ‘Easy Clean flow’ magnet from Dutch company Goudsmit Magnetics recently underwent a redesign.

The magnetic separator removes metal particles and weakly magnetic stainless steel particles from powders as fine as 30μm in the dairy and other industries.

The Easy Clean flow magnet is suitable for large product flows and distinguishes itself by the very high magnetic flux density of over 12,000 gauss at the contact surface of the bars. These bars come into direct contact with the product and have a penetrating magnetic field that effectively makes powders and granulates metal-free at high flow rates.

The magnet is dustproof to an overpressure of 0.5 bar and has an electro-pneumatic controller. The cleaning requires 6 bar air and 24 VDC start signals.

High separation yield

The 50mm diameter magnetic bars provide a high separation yield, have a deep holding field and a high flux density. This ensures that even grade 316 stainless steel particles are captured. To make sure all particles touch the bars, a deflector is fitted.

The large space between the bars results in a significant increase in capacity of the passage, which is particularly beneficial when it comes to poorly flowing powders, Goudsmit said.

Automatic cleaning

Cleaning takes place during a production stop. The product chute must be depressurized. The pneumatic magnetic bars simplify the cleaning process. The guide takes the magnetic bars outside the product channel, after which the magnets in the bars are blown outwards. A plate then retains the captured metal particles, after which they fall into a collection tray.

Sensors detect the position of the magnets. After cleaning, the magnets return to their original position and the product flow can be restarted. With the help of a connection box, it is possible to connect and control the magnet via the central control room. A control box with PLC is optional.

Redesign

The modified design is dustproof from the outside. At the top, a cover plate with gasket ensures that no product can escape to the outside. The side of the magnet has a standard terminal box that simplifies the connection of sensors and cables. Both sides are equipped with inspection hatches for maintenance.
