  ♦  A slow drive device.

Cement Rotary Kiln Processes 

With the arrival of rotary kilns, cement manufacturing processes became sharply defined according to the form in which the raw materials are fed to the kiln. Raw materials were either ground with addition of water, to form a slurry containing typically 30-45% water, or they were ground dry, to form a powder or “raw meal”.

  • In the Wet Process, the kiln system is fed with liquid slurry, the water then being evaporated in the kiln.
  • In the Semi-Wet Process, raw material is prepared as a slurry, but a substantial proportion (50-80%) of the water is mechanically removed, usually by filtration, and the resulting “filter cake” is fed to the kiln system.
  • In the Dry Process, the kiln system is fed with dry raw meal powder.
  • In the Semi-Dry Process, a limited amount of water (10-15%) is added to dry raw meal so that it can be nodulised, and the damp nodules are fed to the kiln system.

Wet process cement rotary kilns 

The original rotary cement kilns were called ‘wet process’ kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry.

A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot of water has to be evaporated and the process of heat transfer is not very efficient.

The slurry may contain about 40% water. This takes a lot of energy to evaporate and various developments of the wet process were aimed at reducing the water content of the raw meal. An example of this is the ‘filter press’ (imagine a musical accordion 10-20 metres long and several metres across) – such adaptions were described as ‘semi-wet’ processes.

 

Through the technical renovations, the rotary kiln calcining system equipment made by ZK has adopted the advanced hydraulic thrust roller device, the high measuring precession plunger pump, the variable speed adjusted valve, the contact graphite block sealing device and the other national advanced technologies. In order to raise up automation degree, the industrial TV has been used at the kiln head for monitoring of kiln, the simulation phosphor screen has been used for display of process flow; the infrared scHangZhou system has been adopted for calcining zone to directly reflect the burning conditions on the computer. With the use of these new of these new technologies, it is direct in vision, convenient in operation and reliable in use. Therefore, the thermal condition can be stabilized and the running rate of equipment can be raised. Compared to same sized equipment, its running rate has been raised 10% up, production has been increased 5% to 10% and heat consumption has been reduced 15% down.

Our company produces other rotary kilns with the diameter1-5 meters, widely applies in the metallurgy, the chemical industry, bears professions and so on material, Ceram site, papermaking. This kind of kiln’s supporting is divided into two forms of rolls and skids, the transmission may use direct-current or the exchange frequency conversion velocity modulation, and has many kinds of form seals to adapt the different operating mode.
