Product Description

Gypsum rotary kiln is an industrial equipment, which can make a lot of production. And the production of gypsum has a great role, mainly used for construction of building engineering, pharmacological treatment, mold processing, chemical industry, cement regulation in many areas, almost became the indispensable in people’s daily life products, so it has a very deep value.

Technical characteristics of gypsum rotary kiln

The processing technology and equipment of gypsum and natural gypsum is not entirely the same, such as in material handling, dust processing, rotary kiln calcination process: physical properties of gypsum and natural gypsum are also different, such as gypsum with high purity, free water, fine particle size; particle size, uniform particle size distribution, poor gradation, standard condensed water, water soluble salt more; it is also worth noting that gypsum and natural gypsum plaster in two different sources, the calcium carbonate unreacted for existence, the main impurities and not completely oxidation of calcium sulfite impurity state is large, the other in the production process of desulfurization technology for the treatment of different. The limestone material, processing of different fineness of limestone will affect the quality of gypsum.

Technical characteristics of rotary kiln equipment

  • The whole gypsum rotary kiln production line automation degree is high, on the material, calcination, the production operation of the finished product transportation, equipment operation monitoring, regulation, alarm and so on by the PLC or DCS control system in centralized control room control. And with the control point of the screen display and the necessary chain monitoring, the production of the operation and operating parameters for automatic recording, and can be printed at any time.
  • Desulfurization gypsum rotary kiln head a material cooling device adopts vertical cooler instead of the original single cylinder cooling machine, to avoid the loss of the sensible heat of lime, from kiln head fall under 1000 DEG C hot lime by heat exchange with the drum into the secondary air, lime can be cooling, the temperature is reduced to 80 DEG C, left and right and output through the vibration feeder. The heat back into kiln combustion air. Waste heat is recycled.
  • Gypsum rotary kiln tail fitted with vertical preheater, the kiln tail about 900 DEG C of flue gas surplus heat conduction to the limestone, the temperature dropped to 230 DEG C around the air outlet pipe into the dust. The waste heat is recovered effectively.
  • The cooler and the kiln head cover adopt the integral design, which ensures the sealing performance and avoids the random emission of the hot air and the dust.
  • Gypsum rotary kiln length diameter ratio from the original 20 to 25 reduced to 14~15. length relationship not only reduced the heat from the surface of the rotary kiln escaping into the surrounding and also reduce the equipment covers an area of, also the transmission power of the kiln body decreases.
