” Smash points sieve calcining kiln ” one step already gypsum, phosphogypsum and natural gypsum production building gypsum powder production line is widely used , the products are widely used in gypsum board , brick , plaster and other production areas . ” Smash points sieve calcining kiln ” one step mainly industrial by-product gypsum gypsum powder production building , the method used is drying – smash – calcination – sorting ( to remove debris ) – modified once, with minimal equipment investment ,
the lowest coal consumption , electricity consumption, the production of high -grade plaster powder and all kinds of products. The production process can be widely used in gypsum, phosphogypsum and natural gypsum calcined gypsum powder production building .
One of the most important process for the drying – crushing – calcination – sorting steps of:
Phosphate had been generated before phosphogypsum ground < 80 mesh ore, after reaction with sulfuric acid substitution phosphogypsum no significant change in shape and size , but often contain a small amount of phosphogypsum not ground phosphate rock , because long-term field stacked often mixed with stones, coal particles , sand, mud, garbage and agglomeration , and the resulting problems are:
( 1 ) pre- drying of these impurities stuck in the wet state of phosphogypsum can not sieve ;
( 2 ) If the separation of these impurities after drying , grinding, will seriously affect the quality of the gypsum into the gypsum ;
( 3 ) agglomeration of phosphogypsum can not guarantee uniformity of calcination .
So calcination kiln drying crushing sieving in phosphogypsum into the kiln drying section to design a set of best smash “flexible grinding device” , only caked not crush other impurities. After the calcination step is completed with the passing of the pneumatic sorting plaster to the next step , all the impurities are separated outside the kiln process , so that the dried, crushed , calcined , sieving step four in the kiln at one go, while gypsum calcination kiln temperature, time , air flow and other parameters can be easily adjusted , the modified calcined gypsum after homogenization , cool storage.
XSM milling machine technology can effectively solve these problems ,
XSM mill products: Raymond mill , vertical mill, high pressure hanging roller mill, three-ring medium speed micro powder mill , Super pressure trapezium mill powder machine , milling machines and other European ladder for barite , calcite, feldspar , talc , marble , limestone, ceramics, etc. Mohs hardness of not more than 7 and humidity below 6% of non- flammable milling and processing mining, chemicals, building materials , metallurgy, construction gypsum powder industries more than 280 kinds of materials , product size in the range of 40-3000 mesh of arbitrary regulation . Which overpressure trapezium mill and ring medium speed micro powder mill is our chief engineer for many years of experience in the fine powder processing , based on painstaking research of new patented products.
