Twin shaft PFR lime kiln, the bar lime kiln, tunnel kiln, types of kiln, Pfr kiln
Handan metallurgical engineering and Research Co., Ltd is the present domestic top professional in lime kiln industry integrating of engineering design, equipment fabrication, installation, operation, training, commissioning, and start-up. So far, we have contracted around 20 sets high efficiency and energy saving Twin-shaft PFR lime kilns.
MER high efficiency and energy saving Twin-shaft PFR (parallal )lime kiln is greatly improved on the basis of traditional twin-shaft lime kiln, by considering the actual situation of steel industry. It adopts the rotating seal, up and down skip, single layer kiln body, which are suitable for national conditions and lower cost requirement. The fuel could be all kinds of gas, solid and liquid fuel. The alternate firing and preheating between two kiln chambers make full use of heat energy. Its main advantage are high activity products and low energy consumption (ton lime per 130 KGSC energy consumption).
MER has a strong ability for supplying the full set of furnaces and kiln equipment, has independent intellectual property rights of high efficiency and energy saving twin-shaft PFR lime kiln.
Parallel flow calcination is the key of twin-shaft lime kiln; it's also proved the importance of the parallel flow calcination in producing high activity lime. In the production practice, this parallel flow regenerative twin-shaft lime kiln can produce the lime activity all above 360ml (4NHCI titration, 10min).We are the manufacturer of lime kiln, we can provide high quality Shaft kiln such as limestone vertical shaft lime kiln, Annular Shaft Kiln.
