Cement, Energy and Environment

moisture content of the mill mixture (Figure 3) was within 3% using a drying unit. This mill is consis ng of two chambers separated by intermediate diaphragm according to the grinding size. At the end of the mill, outlet diaphragm is there to control the finial grinding size. The mixing line is grinded for 40 minutes in the mechano-chemical mill un l the Nano cement is produced as a result of chemical ac va on of modified clinker [10]. Figure 4 indicates the chart of Nano cement produc on steps. For one ton of grind, clinker needs one ton of silica sand and polymeric modifier [say, Sodium Naphthalene Sulfonate] (0.6%–2.0% of silica sand addi ve) in dry form. These simple raw materials used allow overall cost reduc on, and it will be a cost-effec ve line in terms of materials. The mineral added is 25 mm in diameter and gypsum with 5% moisture content. Two tons of Nano cement is extracted. The power cost for one ton of cement is decreased considering the cost for the addi onal grinding and energy [7]. The clinker modifier (Silica sand and gypsum) takes place to adjust the mix before the burning process.
