News ReleaseAir Products Introduces New PolarFit™
Ultra-Fine-Grinding Mill at PTX Canada

Grinding Mill Provides Cost-Effective Reduction of Hard-to-Grind Materials; Achieves Smaller Particle Sizes Versus Conventional Impact Mills

June 20, 2011 Lehigh Valley, Pa.

Air Products (NYSE:APD), a recognized leader in cryogenic grinding, will introduce its new PolarFit™ ultra-fine-grinding mill at PTX Canada in Toronto from June 21-23.

Air Products’ new PolarFit ultra-fine-grinding mill provides a cost-effective way to reduce hard-to-grind materials to smaller particle sizes than can be achieved with conventional impact mills. This flexible grinding system can generate consistent yields of particles between 45 and 250 microns (60 and 325 mesh), and in some cases as small as 10 microns. Now available globally in a range of sizes to match individual customer needs, the mill is ideal for cryogenic size reduction of a wide range of materials, including pigments, plastics, powder coatings, thermoplastic elastomers, waxes, pharmaceuticals, nutraceuticals, spices and other food products.

“The PolarFit ultra-fine-grinding mill offers advanced technology to manufacturers who now may be able to grind product to finer particle sizes, with more uniform particle distribution and higher yields in their target range, than they could before with conventional grinding systems,” said Kimberly King, principal industry engineer for North America Merchant Gases at Air Products. “This can open up opportunities for new applications in a variety of markets.”

Air Products’ ultra-fine-grinding mill uses a combination of size reduction mechanisms, including impact, attrition and particle-particle collision, to achieve much smaller particle sizes than other mills. The mill has an easily adjustable grinding gap, which allows the production of particle sizes from ultra-fine to coarse, eliminating the need for other types of grinding equipment. Through its efficient use of liquid nitrogen, the Air Products mill can produce ultra-fine particle sizes, more uniform particle distribution and higher yields of particles in target range; improve product quality due to minimal or no heat damage; reduce waste and recycling; and lower production costs.

“Air Products’ ultra-fine-grinding mill uses the cooling power of liquid nitrogen to remove heat produced in the grinding process by controlling the temperature of the product or mill,” explained King. “The mill’s higher efficiency helps customers achieve a lower nitrogen-to-product ratio than can be achieved with other mills, further reducing their operating costs.”

Air Products has over 40 years of experience in applying cryogenics to grinding applications. The company provides ongoing technical support from its experienced staff and a reliable gas supply in a variety of modes to meet each customer’s requirements. With state-of-the-art trial facilities in Asia, Europe and the United States, Air Products can test a customer’s product to help them determine the feasibility and benefits of using the ultra-fine-grinding mill.
