Gypsum line machinery manufacturers talk about oxidation and calcination
Source: bethatdrop.com Author: Gaotang Machinery Manufacturing Time: 2019-11-20 17:09:13Desulfurized gypsum is widely used in construction materials and other industries. Its processing and utilization is of great significance. It not only effectively promotes the further development of environmentally friendly circular economy, but also greatly reduces the amount of gypsum mining and protection of resources. Today, gypsum line machinery manufacturers will introduce you to the oxidation and calcination of desulfurized gypsum.
The wet-based desulfurized gypsum is sent to a high-efficiency rotary dryer through a double-screw feeder and a belt conveyor to be dried to remove physical water. The dryer uses high-temperature flue gas to provide a heat source. The exhaust gas from the dryer reaches the standard after being collected by the high-temperature gas box pulse bag dust collector. Dry the desulphurized gypsum out of the dryer and send it to the Fahrenheit mill for grinding. After the sieving and sieving, send it to the boiling calcining furnace. After the desulfurizing gypsum is boiled and calcined, it will be dehydrated from two crystal waters to half crystal water to make mature gypsum powder That is, the desulfurized gypsum powder is usually white, colorless, and the colorless transparent crystal is called mature gypsum. Sometimes it is gray, light yellow, or light brown due to impurities.
1. Whiteness of gypsum line: The whiteness of gypsum line, expressed as a percentage of white content. The plaster line machinery manufacturers are mainly used for interior decoration, which must meet the requirements, and the whiteness of the plaster line should be uniform;
2. Moisture content of gypsum line: There are three methods to describe the moisture content of gypsum line. One is to calculate the moisture content of the plaster line before and after drying, and the other is to calculate the data ratio of water in the plaster line after drying. The third is the volume ratio of the gypsum line to the entire gypsum line; generally speaking, the lower the water content of the gypsum line, the better the quality and the less susceptible to moisture.
3. Gypsum line breaking load: refers to the large pressure that the gypsum line can bear before breaking.
