Gypsum grinding millis also called gypsum stone grinding mill, which mainly used for processing more than 280 kinds of high fine powder materials, non flammable and explosive mines with no more than 9.3 Mohs hardness and below 6% humidity such as gypsum stone, barite, limestone, marble, basalt and slag in metallurgy industry, chemical industry, building materials industry and other industries. The finished product size is adjustable in the range of 80-425 (the finest is 1000 mesh).Now, our gypsum stone grinding mills are exported to many countries, like Nigeria, Libya, South Africa, Vietnam, Indonesia, Philippines, Pakistan, Brazil, Egypt, Zambia and so forth, and acquired high recognition.
After being crushed by crusher machine which include jaw crusher, cone crusher and cone crusher, the crushed particles even now can't meet dimension necessity need to have for being grinded by grinding mills.
Gypsum grinding mill can grind stones or rocks into fine powder. They're widely employed in mining, construction, chemical marketplace, generation, ceramics sector. Unique grinding mill are applied to grind various hardness of stones.
4. The important parts are made of high quality steel, wear resistant parts are made of high performance wear resistant material. The whole machine has high abrasion resistance and reliable operation;
When the material enters into the grinding chamber of gypsum powder grinding mill, with the centrifugal force generated from the rotation of the spindle, the grinding roller will swing outwards to press the grinding ring. The blade scoops the material up to the gap between the roller and ring, with the rolling of roller to realize crushing and grinding purposes. After grinding, the powder materials will be separated by the blower circulating wind through the analysis machine, the rough materials will fall back to the grinding chamber for regrinding.
The qualified fine powder will flow into the cyclone powder collector, and then the finished product will be discharged by the tube. When the air enters into the blower through the powder collector, it will form a closed circulation, which makes the machine work normally and continuously. The left wind will enter into the purifier through the air pipe and then discharged after purifying.
0-3mm / 40-325mesh / 325-2500mesh There are all kinds of grinding mills at SBM which can satisfy various requirements for coarse powder, fine powder and superfine powder production.
Ground Calcium Carbonate(GCC) is usually made by grinding natural carbonate minerals such as calcite, marble and limestone. It can be got by wet or dry process. Currently, dry process is popular at home.
The system of blast furnace pulverized coal has been widely used in Electric Power, Steel and Metallurgical industry etc. In the whole system, the preparation of pulverized coal is the most important step.
To ensure the quality and quantity of gypsum powder production, smart gypsum powder production line which could complete an automatic production is a choice for numerous enterprises.
The JOYAL Three-ring Micro Powder Mill(ultrafine mill) is for super-fine grinding materials with hardness less than 6 in Mohs scale and humidity less than 6 percent such as kaolin, limestone, calcite, marble,talcum, barite, gypsum, dolomite, bentonite mud,mica, pyrophyllite, sepiolite, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment and so on. The granularity of the end products is 325-2500 meshes (0.044-0.0055mm).
General:Crushing -- Grinding -- Selecting -- Collecting Detailed:The main bearing and each dial are driven by electromotor of main equipment through reducer, and numbers of rings and rolls which are rolling in the ring channels are driven by dial through plunger. After being crushed by hammer crusher, the big materials become small ones and they are sent to the storage bin by elevator. The electromagnetic vibrating feeder sends them to the middle of first dial evenly; the materials will be driven to the edge of dial by centrifugal force, and fall into the ring channels and are pressed, crushed and ground by the grinding rings and rolls. Then the materials fall into the second and third ring and crushed and ground. The high pressure centrifugal blower inhales air from the outside and blow the materials which are ground in the third ring to powder Separator. The rotating turbo in the powder Separator makes the coarse materials return to the mill and reground, while the fineness mixes with the air and be drawn to the cyclone and be discharged from the discharging valve which is in the bottom of it. The air which mixed with very little fineness are purified by impulse dust catcher and discharged by blower and muffler.
Kaolin is a common clay mineral in nature and a very important non-metallic mineral. Because of its white color, it is also called dolomite. The pure kaolin is white, fine, soft and soft, with good plasticity, fire resistance, suspension, adsorption and other physical properties. The world is rich in kaolin resources, with a total amount of about 20.9 billion tons, which is widely distributed. Countries such as China, the United States, the United Kingdom, Brazil, India, Bulgaria, Australia, Russia and other countries have high-quality kaolin resources. my country's kaolin mineral resources rank among the top in the world, with 267 proven mineral deposits and proven reserves of 2.91 billion tons.
With the continuous economic development, the role of kaolin in social production has become increasingly prominent, and it is an essential mineral raw material for national economic construction. It is also widely used in industrial sectors such as rubber, plastics, refractory materials, petroleum refining, and cutting-edge technology in agriculture and national defense.
Kaolin is used in papermaking, which can give the paper good covering performance and good coating gloss performance. It can also increase the whiteness, opacity, smoothness and printability of the paper, and greatly improve the quality of the paper.
The powder that meets the fineness is separated and collected in the dust collector through the pipeline through the airflow. The collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged by a powder tanker or an automatic baler.Get in Touch with Mechanic
