May 27, 2016 Roller mills can typi- cally handle raw materials with an aggregate moisture of 15 while ball mills are limited to about 8. Ball mills used for drying should be air-swept using air velocity of 3-4Msec above load. Normally drying is effected by ducting part of the kiln exhaust gas through the mill.
FTIR Analysis. Treated and untreated samples were cut into small pieces and then ground separately in a knife mill Retsch SMI, followed by a Thomas mill. The crushed material was subject to a screening using a Retsch AS200basic with 40, 60 and 80 mesh sieves. The sieving was carried out during a period of 20 minutes at a speed of 50 rpm.
The impressive speed of 2,000 min-1, so far unrivaled in a ball mill, in combination with the special grinding jar design generates a vast amount of size reduction energy. Thanks to the new liquid cooling system, excess thermal energy is quickly discharged preventing both sample and mill from overheating, even after long grinding times.
