Our Zerma PM series of compact pulverizers are high speed, precision grinders for the processing of medium hard, impact resistant and easily crumbled (friable)materials. Typical applications are the pulverizing of plastic profile, tube, sheet, edge trim materials, film waste and also products from the food, chemical and pharmaceutical industries. The material to be pulverized is introduced into the pulverizor through the centre of a vertical 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 resultant powder is collected with a blower and cyclone system.
One piece, concentric grinding disc ensures lower regrind costs. The installation of the disc is fast and simple. New Bearing Technology - the single drive system operating at high speed and high power has a special bearing arrangement to ensure prolonged production times between bearing service. Easily adjusted - The gap between the grinding disc can be easily adjusted to give accurate setting for the required fineness and consistency of product. This pulversizing system can produce powder sizes to below 500 microns and depending on the product, without the requirement for a screener. The design of this pulverizor has been exceptionally well thought out. The small chamber cross section and discs of near flat design; mounted vertically, ensure the infeed material is grasped and reduced immediately on entering the grinding chamber.
