Desulfurized gypsum powder is one of the five major gel materials. It is produced through the processes of crushing, screening, sand making, and grinding, and then processed by drying equipment. It is widely used in building materials, chemical and other industries. However, due to the special properties and high water content of desulfurized gypsum powder, what are the drying methods of desulfurized gypsum dryer?

  Building gypsum processing can be divided into two types: direct method and indirect method according to different heat transfer methods: one is the direct airflow method of the dryer. The direct air flow method is a set of gypsum calcination process equipment developed and designed by the "gas-solid cyclone" drying technology with extremely high heat and mass transfer efficiency. The process unit has a dryer that can use a variety of heat sources, such as flue gas, coal gas, or hot air converted from steam or other energy sources. According to the temperature of the gas source, the dryer can perform low-humidity and slow-speed calcination at 1800 °C, medium-speed calcination at 3000 °C, and rapid calcination at 5800 °C.

  Another is the steam indirect method: the steam indirect method is a set of gypsum drying and calcining process devices that are researched, developed and designed by themselves according to the energy situation and environmental protection requirements of the power plant. The device separates the free water that is easier to get out and the crystal water that is difficult to get out in two equipments, which makes it more reasonable and facilitates the quality control of product structure adjustment. The device can be produced in dihydrate gypsum, such as cement retarder. The heat transfer area per unit volume of the dryer is large, the equipment structure is compact, and the device occupies a small area. The equipment is equipped with a waste heat recovery and reuse device to reduce the energy consumption of the system.

  Our company has been producing drying equipment for more than ten years, and it is more experienced in drying desulfurized gypsum powder. It is tailor-made based on the comprehensive properties of desulfurized gypsum powder—desulfurized gypsum powder dryer, which has a very high drying rate. If you are interested, please contact us.
