A Brief Overview of the Gypsum Production Line
A Gypsum production line consists of a roller mill to grind the raw material and then dry it. The resulting slurry is then mixed with body paper and calcined in an autoclave. After this process, a Gypsum board is formed. The finished product is shipped and must meet import and export procedures. To learn more, read this article. This article aims to provide a brief overview of the processes involved in the production of this product.
Gypsum ore is dried in a roller mill
Drying gypsum ore is a simple process using a roller mill. The ore is fed into the mill in a stream of gas, which is heated by the rollers. The process can be performed simultaneously with no need for a rotary dryer. The finely ground gypsum ore is then known as landplaster, and it is useful for soil conditioners.
The process for drying gypsum involves three steps. First, the gypsum ore is harvested from underground mines or quarries. Then it is crushed further, to a size of 50 millimeters (two inches) or less. Next, the ore is calcined and dried. After this, the ore is ground in a roller mill to a particle size of less than 149 micrometers (m).
The next step in the process is drying the ore, which reduces its size significantly. The process also allows for the removal of residual shale and other waste materials from the ore. The final product is then screened at a density of.157 or 187 in order to remove contaminants. Once this is completed, the ore is ready for reprocessing. You should then be able to sell the dried ore at a high profit margin.
The process of drying gypsum ore is also highly important for manufacturing titanogypsum pigment. It is also produced in industrial processes, and the waste sulfuric acid is neutralized and turned into gypsum. The sulfuric acid is converted back to sulfide by bacteria. Ultimately, this process leads to an accumulation of elemental sulfur in oil-bearing formations.
The process of grinding gypsum ore can be further simplified by using a saturated NaCl solution. This solution reduces water needs, reduces the temperature of the ore and decreases the risk of gypsum binding. This process has also been used to create plasterboard and other products that are made from gypsum. So, the next time you are in need of plaster, don’t hesitate to contact us.
The process of drying gypsum ore involves several steps. First, gypsum ore is supplied to a mill 114. Once the gypsum is ground in the mill, exhaust gas is produced to dry the gypsum. Afterwards, the dried gypsum 116 is collected in a cyclone collector. The process ends with a powder of high purity.
Gypsum slurry is mixed with body paper
A Gypsum production line is made up of six different parts: raw material processing system, mixing system, forming and conveying system, drying system, and stacking system. These systems include a variety of components, such as a bucket elevator, hammer crusher, electromagnetic vibrating feeder, and electric hoist. Each of these parts is crucial in the production of gypsum boards.
During the process, the slurry becomes thicker and loses its fluidity. This mixture then undergoes condensing, and finally hardens, forming a structure with definite intensity. In building construction, gypsum is used for puttying and advanced whitewashing. It is also used for decorative boards and thistle ornaments.
The process of making gypsum board follows strict ASTM standards, and it involves the recycling of waste gypsum. The process starts with crushing gypsum and mixing it with water and additives. This slurry is then fed between continuous layers of recycled paper. Once the gypsum slurry is mixed with body paper, it is chemically bonded to the paper’s core. Once complete, the Gypsum board is dried to remove free moisture and is ready to be shipped to the end customer.
The process of mixing gypsum slurry with body paper starts with the mixing of calcium sulfate. After the mixture is complete, a portion of the slurry is added to the body paper for further processing. In a Gypsum production line, the body paper is used as a finishing material for the finished product. This process can take a long time and involves many steps.
The final step of the process is the application of pigments into the wet plaster. Lime plaster, which is also used for frescoes, is a combination of lime and Portland cement. Similarly, cement plaster is usually applied to masonry surfaces. Exterior fireproofing involves using cement-based spray products. Moreover, the thicker versions of the cement plaster are used for masonry surfaces.
Gypsum board is calcined in an autoclave
This process is based on the conversion of gypsum into fibers, which are then mixed with standard stucco and formed into gypsum boards. The gypsum slurry may contain anything from 1 percent to 100% of fibrous stucco, while the standard stucco may contain eighty to ninety percent standard stucco.
The plant produces different grades of plaster, and this plaster is then dispatched by big bags or silo trucks. This autoclave-based process uses a high-efficiency equipment system and minimizes the energy consumption. Historically, gypsum manufacturing was an inefficient use of energy. It took as much as 60 pounds of water to produce one ton of gypsum. Many attempts were made to make the process more energy-efficient.
The autoclave-calciner works by bringing a reaction time to a specific level. The reaction time will vary from 0.1 to three hours. It relates to temperature, and the lower the temperature, the longer the reaction time is. However, for a successful conversion, it is important to have a reaction time of at least 25%, or seventy percent or ninety percent. The calcined product still contains gypsum fibers, which contribute to its usefulness in a variety of applications.
The gypsum slurry that passes through the autoclave contains up to 70 percent solids. Steam is sometimes blown into the conduit transferring the gypsum slurry. This slurry undergoes further mixing in the mixing device five. This mixing device is fitted with a screw auger. If gypsum powder is calcined in an autoclave, it will be reddish-orange in color.
As a result of the calcination process, three types of phase structures are formed in gypsum: anhydrite II, bassanite, and CG150. The former is the most brittle, and the latter has the highest specific surface area and pore volume. It is a form of anhydrite that has been refined by calcination to increase its density and pore volume.
Aqueous calcined gypsum slurry may contain other additives that are conventional for gypsum board manufacturing. These additives include bond protecting agents, fibers, fillers, and fibrous reinforcements. Each of these contributes to the board’s overall strength and helps the product to hold its shape and prevent delamination. In a recent study, gypsum board was produced with a high-quality gypsum slurry, which was a significant improvement over the previous one.
Cost of gypsum production line
The cost of a gypsum production line depends on the type of gypsum and its accuracy and usage. Depending on the type, cooking, and refinement process, it can range from $ 28.8 to $403.6 per ton. In some cases, the price can go up to $72 million for a line that produces extra-hard white plaster. Generally, the higher the compressive strength, the higher the cost.
The process of manufacturing gypsum boards is highly complex. Various ASTM standards are followed, which set strict requirements on water resistance and strength. The gypsum is crushed, then mixed with water and additives. The slurry is then fed between continuous layers of recycled paper. As the gypsum is rehydrated, the paper becomes chemically bonded to the core, ensuring maximum strength and water resistance. Finally, the gypsum board is dried to remove any free moisture.
The cost of a gypsum production line depends on the size of the plant. The capacity can range from 2 million to 20 million square meters per year. The types of final products include common paper faced plasterboard, fire proof plasterboard, and water-resistant plasterboard. They can also vary in thickness, with the thickness ranged from seven to fifteen millimeters. Typical fuel types include natural gas, coal, and liquefied petroleum gas.
A gypsum production line grinds gypsum by using a dry process. Variable frequency separators eliminate the need for screening, while advanced dust wipers meet environmental protection requirements. There are many benefits of owning a gypsum production line. For one thing, it promotes high-speed development of the mold industry. It also meets the requirements for quality plaster board.
