Cryogenic Fine Grinding of Rubber from Used Tires. Superfine powdered rubber can be manufactured efficiently using a cryogenic process. Liquid nitrogen is employed to cool the feed granules below their glass transition temperature before they are pulverized with counter-rotating pin mills.
The process of making the chemical composition comprises the steps of filling a mixer with 30-60% by weight of hot water and adding 10-20% by weight of barium carbonate or strontium carbonate, 10-20% by weight of phosphoric acid (75%), 5-15% by weight of lime, and 10-20% by weight of boric acid; mixing the contents for 10-15 minutes to create a wet slurry; pouring the wet slurry into an ...
A disc mill is used to pulverize solid materials. The material is placed between two discs, one of which rotates. Sorting is automatic, producing particles of uniform size. Disc mills often are used to pulverize ceramics, ore and construction materials. Disc mills can have a vibrating feature.
Advanced cryogenic grinding solutions use a combination of size reduction mechanisms, including impact, attrition and particle-particle collision, to meet the specific needs of the production process. These systems also are highly flexible and easily can be adjusted to help regulate particle size. For example, by adjusting the grinding ...

Video credit: shsbjq / CC BY-SA 4.0 Specifications. Important specifications when selecting grinding mills and pulverizers include, The size of the mill can range from pilot/lab to production, e.g., 3.5 to 1600 cu. ft.; Feed size, material, and hardness of feed must be considered.; Output size ranges.; Mills can handle dry or wet input, or both.; Mills operate in batches or continuously.
Ultra-fine Particle Grinding. OGL's cryo grinding process produces much more finely ground particles than conventional milling methods. OGL cryo mills are able to grind many materials to 10µm average particle size or smaller. This improves the particle flow of polymers and dispersion potential for processed polymers and foodstuffs in liquid.
