Also we known ,lime rotary kiln also called lime kiln, is specialized kiln for processing lime, the fierce market competition, the level of production has become a decisive factor in lime manufacturing enterprises to survive, so how to increase lime production has become an important issue for lime production enterprises.Chaeng(Great Wall Machinery Co., Ltd. )has rich experiencein in lime production line , have a large number of user cases, our company design the lime kiln system is highly automated, energy saving 30% -40% efficiency than conventional rotary kiln.
how to increase lime kiln production?
1, use energy-saving burner, automatic control with optimal air flow and reduce the loss of incomplete combustion of fuel.
2, increase the flow rate of hot air in the lime kiln, can directly improve the heat and mass transfer coefficients, so that the drying rate increases, but also enough timely replacement of hot air, hot air drying is conducive to the diffusion and materials. However, hot air flow rate increase will also reduce the hot air in the lime kiln residence time, may affect the lime kiln thermal efficiency, resulting in a certain degree of heat waste. In this regard, it can be transformed or adding lime rotary kiln length to solve within the lifting plate.
3, installed in the rear vertical preheater rotary kiln, rotary kiln full advantage of the high temperature combustion gas, the material inside the preheater, so that the material partially decomposed in the preheater, the system production increased 40 % thermal efficiency increased by 30%.
4, feed size and uniformity of the lime kiln drying process, the drying rate is constant, the material and the hot air contact area is larger, the drying effect will be better. The smaller the particle size of the material, the less resistance in the lime kiln is conducive to improve the drying rate. And feed is a prerequisite to ensure a uniform flow of materials are, both to ensure a stable lime kiln thermal system, and it helps exhaust mastery and control.
5, install a vertical cooler in the rotary kiln head, full use of lime kiln 、lime discharge temperature sensible heat contained in the secondary air is preheated to 600 ℃, the thermal efficiency is improved.
6, across the board to automatic control.
