Air Products has unveiled a new ultra-fine-grinding mill, PolarFit, at the PTX Canada show, being conducted from 21 to 23 June 2011, in Toronto.
PolarFit ultra-fine-grinding mill
The PolarFit produces tiny particles from hard-to-grind materials cost-effectively when compared to traditional impact mills. This versatile grinding equipment can produce a steady output of particles with sizes ranging from 45 to 250 µm, and in certain cases as tiny as 10 µm.
The ultra-fine-grinding mill is suitable for cryogenic size reduction of numerous materials such as spices, nutraceuticals, pharmaceuticals, waxes, thermoplastic elastomers, powder coatings and plastics. It couples size reduction mechanisms such as particle-particle collision, attrition and impact to attain particles with sizes smaller than competitive mills.
The PolarFit features a simple-to-adjust grinding gap that makes it to produce coarse particles and in turn avoids the requirement for other kinds of grinding mills. It uses liquid nitrogen effectively for producing high volumes of ultra-fine particles in the specified target range with uniform particle distribution.
Air Products’ grinding mill enhances the quality of the final product, as there is less or no heat damage and also decreases waste and recycling, resulting in lower manufacturing expenditures.
According to Kimberly King, who serves as principal industry engineer at Air Products’ North America Merchant Gases, the PolarFit’s ability to produce ultra-fine particles can find applications in numerous industries.
