In China, lime rotary kiln production line with a daily yield of 150 tons to 600 tons has successfully adopted a single gas or gas heat exchanger designed and manufactured with inorganic heat conduction technology,which can preheat the gas and primary air to above 180 ℃, it enhances the theoretical combustion temperature, and reduces the exhaust gas temperature to about 160 ℃,
Cement rotary kiln is the main equipment for calcinating cement clinker and it is widely used in cement, metallurgy and chemistry. This rotary kiln machine is mainly composed of cylinder, supporting device, supporting device with catch wheel, transmission device, movable kiln head, kiln tail sealing device and calcining device. and it is favorable for dust removal.
In order to reduce the return material in horizontal lime kiln, kiln feed end can be equipped with a certain slope or spiral guide plate, so that the material at the cutting point moves rapidly to the kiln under the action of the guide plate, thereby avoiding the excessive accumulation of material in the feeding place and returning a lime pit body, it can reduce or even eliminate the rotary limestone kiln feed back problems, thereby improving the kiln production.
For lime rotary kiln production line under 1000t / D, waste heat is small, it can be used to preheat the mixed gas of low calorific value and combust air once, which not only makes full of waste heat, but also reduces the heat consumption. We are large-sized company specialized in production of rotary calcination kiln which always provide the best product and service for customers. Energy saving and emission reduction,secondary energy recycling is the requirements of China limestone rotary kiln sustainable development, waste heat from a preheater waste gas in the lime kiln belongs to the low temperature waste heat. The temperature of waste gas coming out from the preheater is between 220 ~ 280 ℃, which also contains waste heat can effectively utilize accounts for above 25% in the exhaust heat.
