Gypsum production line details date 庄鸿耀 Machinery Co., Ltd. since 1990 and engaged in the research and design of powder technology drying, calcination, heat source equipment on natural gypsum, chemical gypsum engineering applications, the company is committed to the research process and equipment, and design and technology to adapt to the special equipment, through continuous accumulation of experience in technology and engineering systems design, special process equipment manufacturing applications performance and won praise from customers. Hung Yao in the international promotion of energy saving call, focusing on chemical gypsum composite applications research, from the market demand, the introduction of building gypsum powder process, block the plate process, retarder technology, plaster craft, Alpha plaster lamp technology advanced preparation process, in order to meet market and customer needs. Building gypsum powder (? Hemihydrates) alpha (T) gypsum plaster gypsum board self-leveling floor cement retarder for gypsum plaster powder dry calcination process described in the production of calcined gypsum products, product quality control process is the key to the East Powder-step introduction of large, two-step process, de calciner, de dryer, inside and outside the hot boiling heat oven is suitable for different ways for different products and equipment process for ways to form a complete industrial system. In the choice of firing system, to consider the production of the product's use, local heat, power conditions, the degree of automation, production scale, and to determine the calcination and supporting systems. One-step calcination process systems by Yao Hung Machinery Co., study design de calciner, is drying, calcination, broken up a machine to complete the high-efficiency equipment, also known as the one-step process equipment, mainly used in coal, gas natural gas for heat, the use of post-combustion gas direct heating, calcined gypsum. Process: For the calcined gypsum principle fed by the feeder change calciner, under mechanical action of hot air and gas produced dispersancy, material through the dispersion, dried, calcined, and strong homogenization speed, calcined gypsum from the discharge discharge port. Exhaust back out of the furnace by trapping dust collection, after collection of gypsum into the silo by conveyor equipment features automatic control technology, small changes in temperature range, stable product quality. Directly used for the production of wet material, set drying, calcination, broken up in one, low operating costs, product level with the management. Drying, calcination time is adjustable, is conducive to setting time adjustment. Adaptation of scale continuous production, heat can be used in many ways, can be directly or indirectly heated calcining plants can also be used to make industrial flue gas exhaust heat. 1. calciner feed inlet 2. 3. 4. trap spout 5. drying silo de + boiling heat oven 1. 2. 3. dryer inlet 4. roaster 5. Discharge (half water gypsum) 6 silo system uses a two-step calcination process de dryer, using internal and external heating or de fluidized combustion furnace for combustion, the formation of the two-step mode of operation, the two-step powder made by East France initially to consider the use of the plant process steam for heat, steam will be used to swap out the heat exchanger network for the dry heat. And the use of steam in direct or indirect way for calcining heat, East powders based on the user's heat mode, determined by the above two-step dry firing. A use of de dry calcined + B + boiling using dry heat oven 1. 2. 3. feed inlet 4. de dryer 5. 6. silo roaster plant gypsum my company uses a two-step approach to drying calcination. Second step is about to be completed in two drying and calcining equipment respectively. Used are de air drying and fluidized oven combination, air dried and kiln combinations. Here steam to heat the two-step calcination process. Steam as the heat source is suitable for power plants of heat Hemihydrates form. In plant steam as the heat source, its vapor pressure is generally 0.8 ~ 1.6MPa, the steam temperature of 180 ~ 300 ℃. Annual output of 100,000 tons of gypsum powder production line construction. Steam for heat, steam temperature of 300 ℃, pressure of 1.6MPa. By comparison opt de dried in a drier according to the characteristics of the sulfur gypsum, selection fluidized calcining furnace. Gypsum powder production building. Building plaster powder performance parameters Project Excellence for standard units of measurement National Gypsum electropositive flexural strength (2h) MPa 2.5 3.85 Compressive Strength (2h) MPa 4.9 8.95 Setting time initial setting Min: s 6:00 10:30 Final setting Min: s 30:00 16:00 standard consistency water% 64 building plaster powder radioactive Item Unit of measurement data to detect radioactive radium content index 226 Ra Bq / Kg 4.46 electropositive national standard GB6566-2002 thorium content of gypsum 232 Th Bq / Kg 0.33 irradiation index: 1.0 in the exposure index: 0.0 potassium content 40 K Bq / Kg 11.57 external exposure index: 1.0 external exposure index: 0.0 Example Two: Making cement retarder (200,000 tons retarder) using coal as a heat source, the use of combustion flue gas, with de calciner step process, you will receive the phosphogypsum by screening impurity iron, by the conveyor input calciner, phosphogypsum and calcined gypsum mixed then granulated form spherical retarder products. Example three: one-step process using gypsum blocks, after two-step calcination process phosphorus, sulfur calcined gypsum, after further deployment, mixed into the block production machine, can produce high-strength gypsum building blocks. Coal Kaolin new process: ore (Block) → jaw crusher (5 ~ 10μm) → Raymond (325μm) → wet grinding (stripping machine) (- 2μm) → frame filter (40 to 50% hydrous cake) → dynamic dryer (≤1% aqueous powder) → broken machine (solution fine) → Dynamic calcined (80 ° whiteness calcined clay) → tone brightening when calcined (90 ~ 93 ° whiteness calcined earth ) → broken machine (Xie fine) → packaging machine. The company has consistently adhered to: customer first, good service, quality first, the purpose of leading technology, with high quality products, good reputation, quality of service and look forward to joining you, welcome you to visit our company.
