Preheater Parts
Sat at the top of the preheater, we designed our double separator to enlarge the distance between dip tube and cyclone outlet. We also incorporate a longer-than-standard dip tube. The result is a higher separation efficiency of 96% and dust losses of just 25 g/m 3. With such high separation efficiency, raw meal recirculation is reduced to a ...

Preheater and calciner
RCL's preheater cyclone tower is 108 meters tall. Raw meal is fed from the top of the tower, and it travels from there to the bottom through several cyclones. Each cyclone in the preheater serves as a heat exchanger and a separator. Heat generated and released by the hot gases in our kiln is used in the preheaters to promote energy efficiency.

Dipping tube
As the raw meal travels through the preheater, it takes in heat generated from the hot gases it is exposed to. The cyclone dipping tubes are shielded by several rings stacked on top of each other to make up the entire dipping tube. After the preheater, the material moves toward the inlet shaft located at the front of the rotary kiln.
