The SD Dry Grinding Attritors can be operated in both continuous and batch processing applications. In the continuous operation, the material is fed into the vessel at the top. It then migrates through the agitating media bed where it is processed to a desired particle size and is discharged through metering bar grids at the bottom of the tank.

Spray dry scrubbing for emissions control has emerged during recent years. Worldwide, more than fifty spray dry scrubbers are in operation or under construction for the control of SO 2 on coal fired boilers. Virtually all of these units utilize a slurry of slaked lime as a reactive agent for SO 2 capture. The cost of lime is several times the cost of …

The limestone fillers content in cement has no real influence except at 7 days (Fig. 12b) where the dry shrinkage is more substantial when the fillers content and/or the finer grinding are high. The acceleration in hydration (see previously), which induces autogenous shrinkage at early age, is probably the cause of this increase.
