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.
Jun 14, 2016· Cryogenic grinding is used for heat sensitive products and oily spices. The temperature of the feed material is reduced to -55 degrees centigrade which makes the material brittle and easy to grind.
A substantial rise in the specific surface areas of the ground powder was found (3278.56 and 4326.41 for hand pounded and ambient grinding respectively, to 24181.55 cm −2 cm −3 when adopted cryogenic grinding), as the temperature and time of grinding went down as demonstrated in Table 2 (p ≤ 0.05).
Therefore, a cryogenic grinding system was designed and developed to cool the spices before feeding to the grinder and also maintain the cryogenic temperature in the grinding zone.
