PM
High speed precision
pulverisers
Description The disc pulverisers of the Zerma PM series are available with disc diameters from 300 to 800mm. These pulverisers are high-speed, precision grinders for the processing of medium to hard, impact resistant and friable materials. The material to be pulverised 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 Zerma PM series pulverisers is the pulverisation of PVC regrind in pipe and profile recycling. Working in-line with a shredder and granulator to have a balanced and efficient system to handle in-house production waste. Another application is the grinding of PE for rotational moulding applications, here the PM Pulveriser 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. Advantages
