Gypsum Powder Manufacturing Process

Based on over 20 years of research and development experience in plaster making equipment, Liming Heavy Industry Technology has developed a patented technology for the production of high yield and high energy plaster powder. This technology is a dry production method that achieves self grinding and self selection. Through a frequency conversion high-speed powder separator, plaster can be directly ground to meet the GB/T9776-2008 standard for building plaster, without the need for external screening or sorting. At the same time, due to the use of internal circulation air, plaster powder that meets the requirements of the finished product can be quickly blown out, completely avoiding the phenomenon of overgrinding, greatly improving production yield and efficiency; Meanwhile, due to the use of advanced dust collectors, the system meets national environmental protection requirements.

The construction plaster powder processed through this equipment equipment has good product quality. Due to the use of low-temperature heat sources, plaster is not easily overburned. As long as the discharge temperature is controlled appropriately, the finished product does not contain dihydrate plaster, anhydrous plaster is only within 5%, and the rest is semi hydrate plaster. This composition is ideal and the physical properties are also very stable.
