    How to Reduce the Fuel Consumption in Rotary Kiln | My Blog

    Oct 20, 2012 The rotary kiln with big kiln capacity usually choose the straight kiln type, and the rotary kiln with small kiln capacity usually choose the vase kiln type, because the vase kiln type has a relatively higher heat efficiency and lower fuel consumption. 2. The material going to be roasted has a great effect on the consumption of fuel
