Crushing and sieving calcining kiln" one step has been in the domestic desulfurization gypsum, phosphogypsum and natural gypsum production building gypsum powder production line in a wide range of applications, products widely used in gypsum board, gypsum block, and other production areas. " Crushing and sieving calcining kiln" one step method is mainly used for industrial by-product gypsum production building gypsum powder, the method is that the drying - grinding - to - sorting (to remove the debris ) - modified once completed, with minimal equipment investment, the lowest consumption, power consumption, the production of high-grade plaster powder and a variety of products. The production process can be widely applied to gypsum, phosphogypsum and natural gypsum calcination production building gypsum powder.

One of the most important processes for drying, grinding, calcining and separation processes:

Phosphogypsum is generated before the phosphate has been ground into powder by sulfuric acid >80 orders, replacement reaction of phosphorus gypsum shape and size did not change significantly, but often containing a small amount of phosphogypsum without ground phosphate rock, because of long-term field stacking is often mixed with stones, coal, sand, mud, waste and caking, resulting in the problem with:

(1) drying before these impurities stuck in wet state of phosphogypsum cannot divide sieve;

(2) after drying without separation of these impurities, grinding into plaster will seriously affect the quality of gypsum;

(3) the caking of phosphogypsum can not guarantee the uniformity of roasting.

Therefore, drying and crushing and sieving in phosphorus gypsum calcining kiln, kiln drying to optimum crushing section design of a group of" flexible pulverizing device", can only be crushing caking, not crush the other impurities. Calcination process is completed by pneumatic qualified plaster sorting to the next procedure, all the impurities and separate kiln outside processing, drying, crushing, the calcination, screening four processes in the kiln to make smooth reading, at the same time the kiln calcined gypsum temperature, time, quantity and other parameters can be conveniently adjusted, after calcining gypsum modified, homogenizing, cooling storage.

Liming heavy industry science and technology milling machine can effectively solve these problems, liming heavy industry science and technology mill products are: Raymond mill, vertical mill, high pressure suspension mill, three-ring medium speed powder mill, overpressure trapezium mill, Continental trapezium mill, suitable for barite, calcite, talc, feldspar, marble, limestone, ceramic and other Mohs hardness less than level 7, humidity below 6% non flammable and explosive mining, chemical, building materials, metallurgy, building gypsum powder industry in 280kinds of material milling processing, the product particle size in the40-3000range of arbitrary regulation. The super pressure trapezium mill and tricyclic ultrafine mill is my company's chief engineer in the fine for many years engaged in milling process based on experience, devote themselves to the development of new patented products.
