It has been established that about 710% of the cement can be lost due to uncontrolled emissions in the cement mill [ 21 ]. Some studies show that 45% of dust emissions are due to the furnace's supply, while other dust emission sources are crushers, clinker coolers, grinding, and material handling equipment [ 35 ].

steep rise in the cost of oil has caused many plants to convert back to the use of pulverized coal as their primary fuel for the firing systems. At the present time the majority of cement plants are using coal as the primary fuel. For startup of kilns, boilers, and furnaces the use of liquid fuels is still a common practice.
