Advantages of Tunnel Kiln

Advantages of Tunnel Kiln Tunnel kiln has a number of advantages. 1, Continuous production, short production cycle, high yield, high quality. 2, It adopts countercurrent principle, and therefore high thermal efficiency, fuel economy, because the use of heat and waste heat to maintain very good, so it saves fuel.

Kiln Energy Efficiency

neers have produced the most thermally efficient Rotary Kiln available on the market today. By combining several unique features on the HK Series Kiln we have maximised their operational capacity whilst minimising the cost of operation. Thermal efficiency is, ultimately, the crucial factor to the successful operation of any kiln.
