MTW138 Grinding Mill For Making Limestone Powder

Project Introduction

The customer had bought two sets MTW138 grinding mill from Zenith to make limestone powder for the power plant desulphurization. Limestone is used as the desulfurization absorbent. Limestone is crushed and ground into powder. Limestone powder is mixed with water to form the absorption slurry. In the absorption tower, the absorption slurry is mixed with the flue gas. The sulfur dioxide in the flue gas is oxidized with calcium carbonate in the slurry and air blasted from the lower part of the tower to form calcium sulfate and calcium sulfate. After reaching a certain degree of saturation, the crystal forms dihydrate gypsum.
