The gypsum rotary kiln developed by Hongji in combination with the new technology is the main equipment for the initial processing and refining of gypsum ore. The gypsum rotary kiln has strong adaptability and can calcine high melting point materials such as gold ore, iron ore, and copper ore.
Gypsum rotary kiln production mechanism is the same as the traditional rotary kiln equipment, and materials from the preheater into the gypsum in the rotary kiln, the cylinder under constant rotation, the material from high-end to low-end, occurred in the process of moving heat transfer, temperature of material, so that the material produces chemical reaction, the clinker burning, discharged from cylinder bottom after cooling process such as treatment, can get the finished product.
Rotary kilns are similar to cement kilns, but the main difference is the reverse flow of gypsum. Gypsum plaster is exposed at 600-650C temperature during feeding in the kiln, at the end of the kiln it occurs around 150-160C.
Calcination; after crushing process gypsum size is reduced to 0-8 mm. Sized gypsum feeds the kiln regularly by weighing belt. Gypsum moves through to the kiln depending on inclination and rotation of the kiln then calcined products come out. To reduce size of the calcined grains is transferred to grinding and classification steps.
Gypsum in gypsum rotary kiln is mainly used in construction engineering, mold processing, chemical industry, cement adjustment industry and so on. Gypsum rotary kiln plays an important role in industry business. Gypsum rotary kiln is industrial equipment for the preliminary processing and refining of gypsum ore.
Gypsum is the raw material commonly used in construction, building materials, chemical industry, metallurgy, coating, and other industrial fields. Gypsum is very different from natural gypsum, in which the utilization value of gypsum is higher and there are many ways to process it. The main processing technology is calcination, and the equipment to complete calcination is a gypsum rotary kiln.
The structure of the gypsum rotary kiln mainly includes the kiln head, kiln tail sealing device, supporting wheel device, retaining wheel device, supporting device, rotating barrel, coal injection pipe device, etc. The overall structure design is relatively reasonable.
