In order to help the development of green production, green building industry, cement grinding to enhance efficiency, reduce the energy consumption of cement grinding, chaeng introduced a new energy saving and environmental protection lime kiln,cement vertical mill, energy conservation has become a weapon.

A cement vertical roller mill is the real green energy efficient grinding equipment, optional equipment is the best cement industry cement production lines. The system is saving 3-5 degrees per ton of cement compared with roller press processes. It is reported, chaeng( Great Wall Machinery Co.,)cement vertical roller mill single electrical energy consumption 25kWh / t, that is to say: only a 5000TPD cement clinker grinding Energy Saving: 15kWh / tX5000t / dX300d = 2250 Wan kWh (i.e. year cement clinker grinding degree can save 22.5 million), energy-saving effect is very obvious.

Second, environmental protection lime kiln with respect to traditional shaft kiln, it has an absolute advantage in terms of production, coal, lime activity, burning loss rate.

According to "China Industrial green development" Thirteen Five "planning" predicts that by 2020, China's carbon dioxide emissions will be reduced 22% relative to 2015. Energy consumption decreased by 18%, industrial solid waste comprehensive utilization rate of 73%, low-carbon green energy accounts for the proportion of industrial energy consumption to 15%, the basic form of green industrial development mechanism.
