Ring magnets are permanent magnets that are distinguished by their shape: they are round with a hole in the middle, and because of this shape they are sometimes referred to as donut magnets.

General description:Â
The disc grinding  machine pulverizer machine  of the PNMF series are available with disc diameter from 300 to 800 mm. These plastic pulverizer machines are high speed, precision grinders for the processing of medium hard, impact resistant and friable materials. The material to be pulverized is introduced through the centre of a vertically fixed grinding disc which is mounted concentrically with an identical high speed rotating disc. Centrifugal force carries the material through the grinding area and the resulting powder is collected with a blower and cyclone system. Depending on the application the machines can be equipped with one piece grinding discs or grinding segments.

Applications:
One of the main fields of use for the PNMF plastic milling machine is the pulverization of PVC regrind in pipe and profile recycling. Working in line with a shredder and granulator to have a balanced and efficient system tohandle in house production waste. Another application is the grinding of PE for Rotomolding applications, here the PM Pulverizer is used in the production process to create the powder needed in the process. In this process a screening machine is necessary to ensure the right output size, distribution and flow properties of the ground material.

Ring magnets are most commonly used in science experiments, although they also have medical applications. Some people have implantable cardioverter-defibrillators, or ICDs, that automatically apply shocks to their hearts if the rhythm develops irregularities. If the devices malfunction, they can shock the patients unnecessarily, leading to irregular rhythms and possibly death. Medical personnel sometimes place these magnets on patients` chests over the ICDs to disable the devices.
Ring magnets are similar to discs, but feature a hole in the centre. The reduced volume of the magnet results in less strength, but increases their versatility - rings slide easily onto tubes or rods. Rare Earth rings are available in sizes from 6mm outer diameter up to 120mm, and with a variety of internal diameters and thicknesses.
