desulfurization gypsum rotary kiln Description
gypsum is devided into natural gypsume( dihydrate gypsum, anhydrous gypsum), chemical gypsum( phosphogypsum, desulfurization gypsum ) and other kinds.
calcine gypsum is mainly remove part of or all crystal water by calcine.
the rotary kiln formed by kiln body, sealing device,driving device, supporting device and covers.The rotary body is circled by steel plate,firebricks are inlaid inside the body, there is 3.5% slant angle between the rotary body and horizontal line, three tyre belts are supported on three Supporting devices separately, and a big gear ring is installed in the middle of body. The body is drived by motor----speed reducer-----little gear ----big gear.

rotary kiln equipments Features:
1. Through technological innovation, our rotary kiln is designed with international leading wheel catch device, high precision plunger metering pump, high accuracy speed control valve and contact graphite block sealing device, etc.
2. In order to improve machinery automation, an industrial computer is used for showing the calcining condition, and a fluorescent screen is adopted for showing the simulated process flows. An infrared scanner is utilized for transmitting the calcining condition to the computer.
3.These new technologies provide our rotary kiln with strong visual sense, convenient operation and reliable performance. They help stabilize thermal regulation and improve operation efficiency
