Process for producing alpha high-strength gypsum powder by using industrial byproduct gypsum
The invention discloses a process for producing alpha high-strength gypsum powder by using industrial byproduct gypsum, which comprises the steps of weighing the industrial byproduct gypsum and an additive according to a ratio, mixing the additive in a V-shaped mixer for 20-40 minutes, adding the additive into the industrial byproduct gypsum, and mixing for 20-40 minutes; after uniform mixing, pressing the mixture into raw gypsum blocks through a press machine, and stacking the raw gypsum blocks on a still kettle carrier; feeding the still kettle carrier into a horizontal still kettle for still-pressure dehydration to obtain a semi-finished product; and pulling the dehydrated semi-finished product to a drying kiln for drying, and crushing the dried semi-finished product to obtain the alpha high-strength gypsum powder. According to the invention, the industrial byproduct gypsum can be effectively utilized, the briquetting process is used, the advantages of low cost, high yield and small investment of the dry steaming process are fully played, and the addition of the additive improves the quality of the product, so that the product reaches the level of a liquid phase process product.
本发明公开了一种利用工业副产石膏生产α高强石膏粉的工艺，包括以下步骤：按配比来称取工业副产石膏和添加剂，先将添加剂于V型混合机内混合20‑40min，然后加入工业副产石膏中再混合20‑40min；混合均匀后，将混合料通过压力机压成生石膏块，将生石膏块码放在蒸压釜载具上；将蒸压釜载具送入卧式蒸压釜蒸压脱水内进行蒸压脱水，得到半成品；将脱水后的半成品牵引至烘干窑进行烘干，将干燥后的半成品进行粉碎，即得所述α高强石膏粉。本发明能够有效利用工业副产石膏，使用压块法工艺，充分发挥了干蒸法工艺成本低、产量大、投资小的优势，同时外加剂的加入提升了产品的质量，使得产品达到了液相法工艺产品的水平。
