We design and manufacture devices for new type dry method cement production line, which capacity from 100t/d to 1500t/dclinker. And we can also assist the client in transacting purchaser`s credit or Chinese government`s credit while exporting.
Rotary kiln is the main equipment for sintering cement clinker. The rotary kilns produced by our company can be divided into dry process and wet process. They can also be used for chemical industry, metallurgy industry and etc. Throught technical renovations, the rotary kiln sintering system equipment made by our company has adopted high measuring precession plunger pump, variable speed adjusted valve, contact graphite block air seal and other national advanced technologies. In order to raise up automation degree, indurstrial TV has been used at the kiln head for monitoring of kiln, analog fluorescent screen has been used for display of process flow; Infrared scanning system has been adopted for sintering zone to directly reflect the burning conditions on the computer. With the use of these new technologies, it is directly in vision, convienent in operation and reliable in use. Therefore, the rmalcondition can be raised. Compared to been raised 3-5% up, production has been increased 5-10% and heat consumption has been reduced 15% down.
Rotary kiln belongs to building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials. Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. metallurgy chemical kiln is used for magnetic roasting of iron ore and oxidizing roasting of chrome and nickel in the steel factory; baking high-alumina mine in the refractory material factory; baking chamotte and alumina in the aluminium factory and baking chrome ore and chrome powder in the chemical plant.
Main characteristics of dry-process cement factory:
1. This production line adopts advanced technology and equipment of current cement industry. With the advanced technology and dependable equipment, great economy benefits can be acquired. 2. The high-efficiency low-resistance five-stage cyclone pre-heater and cdc furnace system with high gas adaptability, high classification efficiency, high heat exchanging efficiency and low system resistance will be adopted at the kiln inlet, so as to increase the output of clinker.
3. New technology will be adopted at the rotary kiln head.
4. In the raw meal grinding section, air swept drying mill is adopted. The raw material is dried by waste heat from the kiln inlet to save energy and investment.
5.According to technology requirements of the new dry process rotary kiln, advanced computerized
dcs control system is adopted for the control of main production parts from bottom of raw material blending silos to top of cement silos. And PLC control system is adopted for other parts.
6.Great importance has been attached to the environment protection in the plan. In order to measure up to the environment protection standard, advanced and practicable dust collectors are adopted at
all dust generating points.
