Product Description Product Description Product NameChemical Gypsum Powder Production line Annual capacity15,000 to 500,000 tonsWorking time 24h/day ,300day/year Raw Material Gypsum TypeNatural gypsum oreGypsum powder MeshWithin 220 meshesHeating methodHot 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 automationFully automaticFinal product specificationGypsum powderFuel for the heating system Natural gas,coal,diesel,heavy oil,light oil etcFinished powder bending strength 2.7 Mpa Finished powder compressive strength5 Mpa Production processThe 1st step: Feeding&conveyThe forklift put the raw material into the hopper ,and then from the hopper to the belt conveyor ,then from this belt conveyor to here, also here another belt conveyor .this conveyor is sued to put the raw material into next step.The 2nd step: Pre-DryingFrom the belt conveyor come into the hammer dryer ,(later i will show you the pictures)as you see for the chemical gypsum ,the two point is very important ,the surface water and the crystal water .so in the hammer dryer is used to take the surface water out , in the hammer dryer the temperature is very high around 400-500 degree ,and why have this step ? some factory don't have this step ,this step can make the gypsum liquidity. And then to the next step to the boiling furnace ,it can easy to calcinate ,so we have this step . The 3rd step: Bad dust collectorThe bag dust collector, the main function is recycle gypsum powder to reduce cost.The 4th step: Calcination The powder come into the boiling furnace (calcination ) to remove crystal water and remaining surface water. For our boiling furnace, the special is , all the parts inside ,we divide to 4 chamber. The first chamber we will provide very high temperature ,and this very high temperature is used to dry the left surface water and crystal water.The second ,third ,fourth chamber use lower temperature to provide heat to remove there main crystal water. We use this method to keep the quality of the gypsum. So both part are very important and the gypsum quality depend on this two parts :Hammer dryer and boiling furnace. This part is called the calcining system. About the heat source: the coal-fired boiler or the natural gas burner provides heat. A part of the heat is supplied to the hammer dryer to remove the surface water, and part of the heat enters the boiling furnace to remove the remaining surface water and crystal water. At the same time, the remaining heat of the boiling furnace is recovered to the hammer Dryer . (the temperature of cooked powder is controlled at 80-100 degrees).So the heat usage is very high , more energy save ,other factory can not reach this temperature .The 5th step: Ball millThis part is ball mill, because the chemical powder has quality problem, through modification mill, it can change the characteristic of chemical gypsum powder, make it similar to natural gypsum. The 6th step: Storage After milling, the gypsum powder will come into the silo by elevator. For this part, if you want to produce plaster of Paris, there will be some connection parts to plaster plant. Our advantages of chemical gypsum production line:Features of this hot air boiling furnace technology1-Reduce investment2-Reduce maintenance cost3-Gypsum powder quality adjustable4-The installation period is short and area is small5-energy and power savingOur chief engineer Mr. Xie is very famous in the gypsum field in China, and his technology is recognized in the gypsum powder industry, especially in the chemical gypsum field.Mr. Xie preside over lots of projects,especially large capacity.Only his technology could support project of capacity 400000tons/year.Here is a little story about why our factory protect his technology as a secret.A lot of people in the industry are trying to steal his technology.Even few people tried to steal technology from our installation site.Of cause they failed.The technology is widely proved among the industry because of good quality,easy to operate,low maintenance rate,low energy consumption,and long service life.The most important is lots project owners reported the finished gypsum powder quality is very nice.Many gypsum board plant designate the powder produced by his equipment and technology.The introduction of Rotary kiln:The biggest advantage of rotary kiln technology is that the produced plaster of paris powder has a long setting time. The disadvantage is that it is not easy to seal.Our company increase the gypsum cooling system after calcined in this production line, solve the problem of high temperature of the gypsum powder cause the Raymond mill bearing lubricating oil melt and the bad bearing, which is conducive to Raymond Mill for a long time running, Raymond machine structure is simple, low maintenance costs, the operation and maintenance personnel requirements are not high.The high-temperature flue gas section firstly heats the gypsum powder at intervals to prevent the gypsum powder from generating too much anhydrous gypsum powder in the high-temperature flue gas. This process is indirect heating. The cooled high-temperature flue gas is directly heated with gypsum powder to make full use of heat energy , the temperature of the exhaust gas is low. This process is direct heating.This solution reduces the excessive anhydrous gypsum produced by the disadvantage of direct calcination. The S-type inside the rotary kiln increases the heat transfer area, and it also helps the gypsum powder calcination uniformity better. Case project abroad Case 1: 1-Project name:Natural gypsum powder&board project2-Project capacity: Gypsum powder line:150000ton Gypsum board line : 10Million sqm/year 3-Project technology:hot air technology For this project, our Chief engineer has only taken 5 days to run the whole gypsum powder production line and put it into production after installation, and our customer also felt surprised on it. While some manufacturers need more than one month to finish it or even some are unable to run it for production. Case 2:Chemical gypsum powder&POP projectThis is our chemical gypsum powder project in South Africa. The customer is a well-known local building material supplier. The owner has been in the phosphogypsum industry for more than 40 years.project capacity: Gypsum powder line: 50000 tons/year Plaster of Paris line: 30000ton /yearCase 3:project name:Chemical gypsum powder&POP projectproject capacity:400,000 tons/year-500,000ton /year 3-projecttechnology:hot air boiling furnace technologyThis project is one of our domestic projects with a large capacity of 400,000 tons. The raw material is chemical gypsum powder, and use the production process of hot air boiling furnace. This customer's factory is only 1 hour away from our company, and now he is currently building a second production line and its annual production capacity can be 500,000 tons.Actually we have succeeded more than 40 similar projects in our country.Case 4:Project name: Gypsum powder&board projectProject capacity: 4 factory ,8 lines totallyIn 2008 year: gypsum powder line 50000 tons/year + gypsum board line 8000000 m2/yearIn 2009 year: gypsum powder line 150000 tons/year + gypsum board line 10000000 m2/yearIn 2012 year: gypsum powder line 150000 tons/year + gypsum board line 10000000 m2/yearIn 2018 year: gypsum powder line 300000 tons/year + gypsum board line 20000000 m2/yearSince 2008, the boss purchased 4 gypsum powder projects from us, with capacities ranging from 50,000 tons/year (2008) to 300,000 tons/year (2018).He has now grown to become the largest producer of gypsum building materials in Indonesia, and the quality of his gypsum powder can compete directly with the local Knauf factory and even sell at a higher price.
