Product Description Company Profilegypsum powder machinery manufacturers Yurui (Shandong) Machinery Co., Ltd, is an enterprise integrating gypsum projects R&D, design, manufacturing, exportation, installation, and commissioning. We devote ourselves to helping customers quickly achieve projects establish and qualified finished products producing with our superior experience and strength in design, manufacturing, installation& commissioning. We devote ourselves to helping customers save raw materials, and energy, and reduce the cost of production and equipment maintenance in long term with the most advanced gypsum equipment technology and the most mature gypsum production formula. Product ParametersIntroduction of Gypsum powder production process Natural gypsum generally includes dihydrate gypsum and anhydrous gypsum. In order to get the valuable materials, generally, we get semi-hydrated gypsum through heating the dihydrate gypsum. Here is the process: The calcined semi-hydrated gypsum powder can widely be used for plasterboard,decoration board, gypsum block, stucco gypsum, and molding gypsum, etc. Paramater of Gypsum Powder Machine line Product Name Gypsum Powder Production lineAnnual capacity 15,000 to 500,000 tonsWorking time 24h/day ,300day/yearRaw Material Gypsum Type Natural gypsum oreGypsum powder Mesh Within 220 meshesHeating method Hot air boiling furnace or rotary kilnApplication of the powder Building material like to produce gypsum board ,To make plaster of paris , to make gypsum cornice or ceilingDegree of automation Fully automaticFinal product specification Gypsum powderFuel for the heating system natural gas,coal,diesel,heavy oil,light oil etcPacking method available1-Packing machine 1-2 mouth2-Rotary kiln packing machine3-Iton bag packing machineFinished powder bending strength 2.7 MpaFinished powder compressive strength 5 Mpa Production Process of gypsum powder Crushing System The crushing system can crush large ore from mine mining to an average granularity of 25 mm by one time, is an ideal version of traditional ways of two and three stage crushing. Milling System The mill system will make the gypsum particles into gypsum powder,through the combined action of analysis machine and fan, this mill can meet the fineness of grinding requirements from different users.Calcinating System Calcination system is the key link in the production and processing of gypsum powder, and it is also the most difficult part to master. According to this situation, we have developed a new generation of gypsum powder suitable for various application - a new type of hot air boiling furnace Features Of This Hot Air Boiling Furnace Technology 1. Reduce investment2. Reduce maintenance cost3. Gypsum powder Quality adjustable4. The installation period is short and the area is small5. Energy and power saving Our Advantages Hot air boiling furnace & Thermal oil Boiling furnace Technology Comparison 1 When you switch on and off the production line oftenly:Thermal oil Technology: When you use this technology, the production line switch off, and he oil is still very hot, about 200 degrees The heat from the oil will take too much time to cool. 1) After machine off, the raw material stopped to add: during this cooling time, the heat of oil will be transferred to the exising gypsum powder inside of the furnace. So with too much heat, the powder will be burnt out.2) When start again , when add some new raw gypsum, then the Calcined gypsum and raw gypsum will all be mixed together.Then the finished gypsum powder is so uneven. The oil total about 2-3 tons for one production line, with temperature of 200 degree. So when the production line switch off, all these heat will release to the gypsum powder in the boiling furnace. also the release time is very long.This is why this technology, it is not suitable for some customers that often switch it on and off all the time. Hot air technology: As when it switches off, It is warming rapidly, cooling faster. So this technology is easier for customers to switch on and off the production line often. 2 The danger of Thermal oil technology:Sometimes if workers do not notice that the circulation pump of oil does not work, so the hot oil in the tube is heating all the time and not keep cycle status. In this situation, it will happen big explosion.At beginning the tube of oil will not have leakage oil problem, but after several years of operation, the tube will be aging so it will leak oil and then the dangerous fire will happen in near future. Regards hot air technology no need oil and such kind of problem will not happen, the whole equipment for hot air technology is easy and with less maintenance. 3 The gypsum powder industry development:Before the 2010 year, thermal oil technology was mostly used in China. After 2010 year in China, more and more customer choose the hot air technology as their frist choice. Both technology are very mature for gypsum powder production now . 4 For the thermal oil technology: It needs the thermal oil boiler and thermal oil. The boiler is one set of signal boiler, so after you receive it, it can be used directly, no need special treatment in your warehouse. For the hot air technology, the combustion chamber, it needs to be built with Fire-resistant bricks on your site by our engineer.Like you said the OMV has rebuilt the combustion already. It is mainly because the bricks have drop down which caused by the light oil sticks on the bricks. Such kind situation very less happens to other projects.For this part, also we have made some update. such as the brick size was 11cm. Now we are using 23 cm bricks which is bigger twice than before.This is the patent for our engineer's vertical boiling furnance technology-Mr. Xie To produce a higher standard and stable quality of gypsum powder, the calcination part is much more important part. Our engineer Mr. Xie invented the vertical kind of boiling furnace and has gained a patent for this technology. You can see the above picture: the gypsum powder test report from our domestic customer. The bending strength of powder is more than 3 Mpa, which is much higher than the Chinese national standard of 2.5 Mpa. So this is why the technology of the powder project is most important for you. Only with good powder, then you can produce good gypsum board! Sample project from Yurui1 Our engineer Mr, Xie in Indonesia, this customer in Indonesia who own 4 factories.He bought 4 sets gypsum powder line and 4 sets gypsum board line from 2008 yeas to 2018 year. In 2008 year: gypsum powder line 50000 tons/year + gypsum board line 8000000 /yearIn 2009 year:gypsum powder line 150000 tons/year + gypsum board line 10000000 /yearIn 2012 year:gypsum powder line 150000 tons/year + gypsum board line 10000000 /yearIn 2018 year:gypsum powder line 300000 tons/year + gypsum board line 20000000 /year This large and long investment involves small,middle and large capacity.The largest capacity even exceed local enterprise KNAUF . All the total 8 production lines are running well now Installation Instructions 1-project name: Chemical gypsum powder & POP gypsum powder project2-project capacity: Gypsum powder line: 50000 tons/year Plaster of Paris line: 30000ton /year 3-project technology:hot air boiling furnace technology5-project current situation:Running well6-Project location: African 7-Project introduction: This is our chemical gypsum powder project in Africa. The customer is a well-known local building material supplier. The owner has been in the phosphogypsum industry for more than 40 years. They accumulated the phosphogypsum from power plants over the years, and sold to fertilizer plants and smelters after drying.The customer has independently developed a rotary kiln gypsum powder production line before visiting us, while the finished products produced by their calcination technology could not meet their requirements due to the higher water content of phosphogypsum, In 2017, the customer came to visit and investigate almost all gypsum powder manufacturers in China, and finally chose us, because the customer was particularly satisfied with our gypsum powder boiling furnace technology and hammer dryer technology. It totally help customer solve their problems of high water content of gypsum powder and unstable quality of finished products. The project has been finished and shipped to customer in March 2018. In September 2018, our engineers went to help customers install the machine, and the main engineer went to test and debug the machine in December 2018. It has only taken 5 days to run the machine and put it into production. Customers are very satisfied.
