A raw mill fan is located between the cyclone separator and the bag filter. The circuit will be designed to allow gas re-circulation from the raw mill fan back to the inlet of the mill. The duct of the mill inlet is to be equipped with a fresh air intake in order to adjust the mill inlet temperature.

In a cement plant, the air flow to a raw mill is monitored. The objective of this monitoring is to achieve the highest possible efficiency of the raw mill. Controlling the supply air to such a vertical mill can also lead to considerable energy savings, as the maximum air volume does not always have to be used, but can be adapted to the process.

Cyclone preheaters are also called suspension preheaters. In the new dry process of cement manufacturing, the raw meal must be preheated in the preheater before entering the rotary kiln for calcining.The quality of the preheater in a cement plant directly affects the stability of calcining temperature and cement clinker quality in the kiln.

31 Aug, 2020, 11:30 am. Use of alternate fuels in the Cement Kiln leads to excessive preheater exit temperatures. The Cement plant in Jakarta, Indonesia with a capacity of 7800 TPD, planned extensive use of alternate fuels in the kiln. This was leading to excessive Preheater exit temperatures up to 4300C and was limiting the fan capacity.

The cement raw material mixtures are ground, dried, and classified in the Pfeiffer vertical roller mill. For drying the material, hot gases are directed into the mill. Product fineness can be adjusted within a wide range (0.063 to 0.2 mm). The ground and dried product is separated from the process gas in a cyclone collecting system which is ...

Cyclone Design Cyclone Design Cyclones ensure that the heat from the gas stream is efficiently transferred to the raw meal. With our new high efficiency design we were able to downsize all cyclones by up to two sizes while maintaining the same performance in terms of pressure drop, waste gas temperature and separation efficiency.

The temperature of the gas coming into the raw meal department via the hot gas fan depends on the type of raw material being processed. Typically, the hot gas temperature at the inlet to the raw meal department is 180 °C for the STD ("standard") type and 260 °C for the HS ("high strength") type.The gas flow rate is around 300 kN m 3 /h during normal operation.

Cyclone preheater, also known as suspension preheater, is the main cement equipment commonly used in the new dry process cement production line. It is the main gas-solid reaction unit of the cement raw meal pre-decomposition system, which makes full use of the high-temperature exhaust gas discharged from the kiln tail and the high-temperature flue gas generated by the combustion at the bottom ...
