Products Description
Bellian Five-Stage Cyclone Preheater is the key equipment for preheating raw meal in new dry process cement production lines. It uses the high-temperature flue gas from the rotary kiln to preheat the raw meal, increasing the raw meal temperature from room temperature to about 850℃ and completing about 50% of the decomposition. This greatly reduces the heat load of the rotary kiln and improves production efficiency. Our preheater adopts advanced structure design, which has high preheating efficiency and low pressure loss.
Working Principle

The five-stage cyclone preheater consists of five stages of cyclones and connecting ducts. Raw meal powder is fed into the top duct, where it is mixed with the rising high-temperature flue gas. The raw meal is heated by the flue gas and carried into the first stage cyclone. In the cyclone, the raw meal is separated from the flue gas and falls into the next stage duct. This process repeats through five stages, and the raw meal is gradually heated to about 850℃. The preheated raw meal enters the calciner for further decomposition.

Buying Guide
When choosing a five-stage cyclone preheater, you should consider: 1. The daily raw meal production capacity; 2. The required preheating temperature and decomposition rate; 3. The local environmental protection requirements; 4. The site conditions. We can provide customized solutions according to your specific needs.
FAQ
What is the decomposition rate of the raw meal after preheating?
The decomposition rate of raw meal after passing through our five-stage cyclone preheater can reach more than 50%. If equipped with a calciner, the decomposition rate can be increased to more than 90% before entering the rotary kiln.
How much energy can be saved by using a preheater?
Compared with wet process cement production, the new dry process with five-stage cyclone preheater can reduce heat consumption by about 40%, greatly reducing production cost.
Is the preheater easy to block?
Our preheater adopts advanced structure design and is equipped with anti-blocking devices, which can effectively prevent material blockage. We also provide regular maintenance services to ensure stable operation.
Do you provide calciner together with the preheater?
Yes, we can provide a complete preheating and decomposition system including five-stage cyclone preheater and calciner. This can further increase the raw meal decomposition rate to more than 90% and improve kiln production capacity.
