Double-chamber Shaft Kiln (Maerz Kiln)-Henan Zhengzhou

Features. 1. Parallel calcination: This is the technical feature of the double-chamber shaft kiln. Because the high temperature flame contacts the lower temperature material, the heat exchange rate is very high, and the relatively low temperature hot gas contacts the material to be burned. Avoiding over-firing and under-firing, the roasted
