As the building is smaller in size, your initial investment and civil cost are lower. As this means the preheater operates with slightly increased pressure drop levels, the energy de-mand is slightly higher. 5-STAGE PREHEATER 85 HE 67 Height: approximately 120 -130 m The cyclone diameter depends on the desired pressure drop level,0 m 8,5 m 8,0 m
The rotary kiln system is well suited for converting larger particle sizes and the integration of the cyclone preheater greatly improves specific energy consumption over just a straight kiln. It also reduces the size of the kiln and makes treatment of off gases very simple because the heat is removed prior to treatment.
AGICO Cement, as a professional cement equipment supplier in China, offers different models of quality cyclone air separators for any type and size of cement plants, such as JD series cyclone air separator. It is the latest powder separator developed by our company's technicians with the plane eddy theory.

Rotary Cooler: rotary cooler is the earliest used one in the cement plant.It is similar to the cement rotary kiln in appearance and equipped with refractory lining and material lifting device inside. The high-temperature clinker enters into the cylinder from one end, contacts with the cold air from the other end under the action of the lifting device, meanwhile carries out heat exchange.
The cement roller press has a high energy utilization rate and remarkable energy-saving effect in the material grinding process. In cement plant, cement roller press is a kind of important cement equipment used for clinker grinding. It is usually combined with a cement ball mill to form a high-efficiency cement grinding system because the practice shows that the grinding process with small ...
