Requirements of Refractory Materials for Lime Rotary Kiln
In front of the lime rotary kiln preheating zone is a preheater. The limestone is heated in a preheater with a particle size of 10-30mm, and the temperature of the preheating section is 1000°C. Refractories in this area should be high strength, wear-resistance, and thermal shock resistance. Either clay bricks with better compactness or alkali

The kiln will have a 450tpd capacity for clay calcination, with a heat consumption of 720kcal/kg. Calcined clay capacity then becomes 35 per cent higher than that of its design clinker production capacity.

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.
