GROWMECH Tunnel Kilns are new energy efficient technology - a car pushing type continuous kiln that consists of preheating, firing and cooling zones, suitable for large production of Sponge Iron. The tunnel kilns are capable of using soft ore, and work with iron ore fines comfortably.
Our tunnel kilns are extremely low on environmental pollution; they have uniform product quality and low production cost. The tunnel kilns have the ability to convert Haematite and Magnetite sponge iron, and also work well with coal fines and mill scale.
The tunnel kilns conserve energy by capturing heat at the cooling end and recalculating it to help pre-heat materials that are entering the device. The pre heating, low energy consumption, cooling process are done in the kiln with less energy consumption. Coal consumption is reduced to 45% per batch of production. The tunnel kilns provide temperature conformity, and lower the fuel consumption.
