Limestone Preheater | Refractory Products Limestone Industry
Exhaust gas is drawn out of the kiln, passing through the bed of limestone preparing it for the kiln. The heated limestone is pushed across the floor of the preheater by hydraulic rams. The limestone is ultimately dropped through the feed hopper and into the rotary kiln. The range of temperatures in the preheater varies from several hundred

How Cement Is Made in Rotary Kiln | Rotary Kiln Manufacturer
Once the heated dry meal enters the rotary kiln, it is rotated as it moves downhill towards the kiln’s heat source. This continues the calcination process, while also breaking down the limestone and clay into smaller particles. Eventually, the mixture reaches the bottom of the kiln, the hottest part, and then drops out into a receptacle.
