Desulfurization Gypsum Dryer

Desulfurization gypsum dryer is also known as gypsum powder dryer, and it is indispensable drying equipment in building material industry. At present, this equipment is mainly used for drying materials in mine, chemical, building materials and other industries.

The main application purpose of desulfurization gypsum is to dry it and use it as the retarder of cement, or smelt is as semi-hydrated gypsum for making gypsum board, gypsum block and plastering anhydrite.

Desulfurization gypsum dryer or fgd gypsum dryer adopts horizontal air-swept structure. There is a feeding mouth on the top of the dryer machine and bucket elevator feed the wet materials to the dryer from this feeding mouth. In the upper part of the machine, there is a frequency control spillage plate and V-shaped air classification and separation machine and there are several sets of sliding cones which is fixed inside the machine together with the spillage plate with a cross supporting structure. There is an air counterbalance hole on the solid sliding cone on the foot machine dryer to ensure even ventilation.

With the increase of environmental awareness, the emission control of the sulfur dioxide in coal-fired flue gas emitted by power plant is increasingly tight, for this reason, desulfuration in power plant is imperative. At present, the processing technology and equipment of desulfurization gypsum are not totally the same with that of natural gypsum, such as material conveyance, dust disposal and calcinations technology. Regarding physical property, desulfurization gypsum is different from natural gypsum, for example, desulfurization gypsum has high purity, big free water, fine granularity, even distribution of particle size, weak grading and high adding water amount. In addition, desulfurization gypsum and natural gypsum has different sources.
