attrition mill for limestone in Oman

Attrition characteristics and mechanisms for limestone …

Attrition is very important for limestone particles used to capture SO 2 and CO 2. In this study, the attrition of limestone particles was investigated at room temperature using an air-jet apparatus, based on the standard ASTM D 5757-00 method. The mass percent of fines increased almost linearly with time for 125–850 μm particles.

Attrition characteristics of limestone in gas-solid fluidized …

The attrition rates, R a, of the limestone samples were above 30 mg h −1 after 24 h in the attrition mill at an orifice velocity of 230 m s −1 while it was only 13 mg h −1 for the VPP and 20 mg h −1 for the FCC (Table 2). The attrition rates (based on the mass of elutriated fines collected in the thimble filter) ranked from lowest to ...
