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. We have been deeply engaged in the field since 1994, setting up 100+gypsum projects domestic and abroad. Our engineers' group who only serve for YURUI left a full footprint over Africa, Asia, and South America, more than 20+countries. Our Advantages-Yurui Introduction 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 line Annual capacity 15,000 to 500,000 tons Working time 24h/day ,300day/year Raw Material Gypsum Type Natural gypsum ore Gypsum powder Mesh Within 220 meshes Heating method Hot air boiling furnace or rotary kiln Application of the powder Building material like to produce gypsum board , To make plaster of paris , to make gypsum cornice or ceiling Degree of automation Fully automatic Final product specification Gypsum powder Fuel for the heating system natural gas,coal,diesel,heavy oil,light oil etc Packing method available 1-Packing machine 1-2 mouth 2-Rotary kiln packing machine 3-Iton bag packing machine Finished powder bending strength 2.7 Mpa Finished powder compressive strength 5 Mpa Product Parameters 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 investment 2. Reduce maintenance cost 3. Gypsum powder Quality adjustable 4. The installation period is short and the area is small 5. Energy and power saving Higher quality standard 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
