Vertical Shaft Kiln Vs Rotary Kiln - Reitzindia

Kilns to produce cement are almost equally old. Now cement kilns can be divided mainly into 2 types: vertical shaft kiln and rotary kiln. The vertical kiln is the older type and its origin dates back to the 5 th century AC. Rotary kilns were first used in 1880. Around the 20 th century, they replaced vertical shaft kilns almost everywhere.
