PPS Air Classifier Mills for Ultra-Fine and Controlled Particle Size Grinding

17 Mar 2023  |
The PPS Air Classifier is a vertical grinding mill incorporating an internal classifying wheel with an independent drive. Product is fed into the grinding chamber by either a feed screw or a pneumatic conveying system via a rotary feed valve for ultra-fine and controlled particle size grinding.

PPS Air Classifiers are manufactured in carbon or stainless steel and can be designed to withstand 10 Bar EPSR. All machines are uniquely designed with either a single or double-opening grinding chamber to facilitate easy cleaning and maintenance. PPS Air Classifiers also has a versatile drive mounted either above or below the grinding chamber base. Most PPS Air Classifiers are fitted with manually operated gear units for lifting the grinding chamber cover lid with the exception of the 8 and 10 PPS CMT models, which are fitted with a motorized gear drive for lid opening.

Applications

PPS Air Classifiers are supplied for either batch process or continuous operation.  They are designed for all industries that produce fine powders where control of the particle size distribution is required. Typical applications are found in the following industries, Chemical, Minerals, Pharmaceuticals, Food, Powder Coatings and many others. All systems are designed to handle both inert and explosive applications where venting or containment is required.
