The dry crude materials enter the kiln outlet, i.e. the high end of the cylinder through the preheater, and then are fed into the kiln by the tremie pipe. Due to the inclination of the cylinder and slow rotation of the material, the materials roll in hoop direction. On the other hand, the materials move from the high end to the low end, where they are decomposed, burnt, cooled in succession. Thus they become cement clinker, and are discharged from the low end of the cylinder. Finally, they enter the cooling device.Tow-girder burning device is the central part of the lime rotary kiln. Some fuel (such as gas .liquid and solid) feed pipes are placed into the girder the burner mixes fuel with the combustion air even. The quantities of burners on the level are the same. This makes the rotary kiln’s section temperature distributed even to cut down raw-burner rate and raise lime activity. It is aslo widely in building materials, metallurgy, chemical industry, construction, environmental protection industries. We can design the whole cement production line, including ...
... making the clinker from crushing, powder concentration, calcinating of raw material and milling by Cement Mill and packing. During the whole process, there will be cyclone for dust collecting.In order to protect the burner girder working at high temperature in the calcining zone, medium (water or heat oil) enters the burner girder sand-witch and circulates to cool. Medium (water or heat oil) passes the cooler to cool. Reduces temperature and circulates .primary air preheated by waste air, passes the burner girder and enters the rotary kiln. Heat energy is made full use of .Safely when medium (water or heat oil) temperature rises above certain temperature, the stand-by pump makes spurn medium (water or heat oil) can keep circulating.At the present, Hongxing mining machinery has set up three state level machinery research institutes, and we also produce various kinds of cement miller, rotary cement kiln and free service for assembling various kinds of production line. rotating drying kiln: http://www.china-ore-beneficiation.com/ournews/n263.html
