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 3-4M/sec above load. Normally drying is effected by ducting part of the kiln exhaust gas through the mill.Mar 02, 2014 In this study, Jordanian feldspar from Wadi Al-Jayshiah area was invested to evaluate its applicability as raw material for ceramic and industries. The chemical analysis indicated that the average Fe 2 O 3 content is 2.33%, which is very high, compared to commercial ceramic and glass grades feldspar.
