Product Description

We design and manufacture devices for new type dry method cement production line, which capacity from 300t/d to 4000t/d clinker. 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.

Remark:According to the requirement, the kiln length and driving system can be revised.
★ means the rotary kiln match with vertical pre-heater
Main spare parts is 1, sealing plate, 2. Oil sealing, 3. Nylon pin 4, Rubber block 5, Kiln head back plate.

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.

Production Process Introduction
Mined limestone is transported by conveyors to the crusher for crushing. Crushed limestone is ground by ball mill or vertical mill into powder, and then transported by conveyor to the raw material silo for storage and further mixing. After homogenization, raw material goes into the preheating system for decomposition. The decomposition rate is about 95%. After calcined in the rotary kiln, raw material becomes clinker. Clinker, gypsum, and other mixed materials are ground in ball mill into cement of qualified fineness. Powder separator is used to adjust fineness of cement to achieve energy-saving production. Packaging machine and automatic loading machine are used to pack and deliver bags of cement.
