For the vertical shaft lime kiln, as the name implies, is vertical. And all the processes can be done in the vertical lime kiln alone. As for capacity, rotary lime kiln can produce quicklime with larger capacity than vertical lime kiln. Daswell rotary lime kiln can produce quicklime 150-1200 ton/day, while the capacity of vertical lime kiln is ...
The rotary kiln system is well suited for converting larger particle sizes and the integration of the cyclone preheater greatly improves specific energy consumption over just a straight kiln. It also reduces the size of the kiln and makes treatment of off gases very simple because the heat is removed prior to treatment.
