China has proved reserves of gypsum are very rich, ranking first in the world. There are many type of gypsum causes, mainly is vapor deposition deposits, often in red, gray, gray, dark gray sedimentary rock, and symbiosis with rock salt. According to different classification criteria, Gypsum can be divided into many forms. According to the physical components it can be divided into phosphorus gypsum powder, gypsum powder, citric acid, gypsum powder and fluorine gypsum powder; According to color, it can be divided red gypsum powder, yellow gypsum powder, green gypsum powder, white gypsum powder, blue gypsum powder; according to physical characteristics it can be divided into dolomitic gypsum powder, clay gypsum powder, chlorite, gypsum powder, alabaster powder, talc gypsum powder, containing sandy gypsum powder and fiber gypsum powder; according to the use it can be divided into building materials gypsum powder, chemical gypsum powder, gypsum powder mold, food gypsum powder and casting with gypsum powder.
In the construction area, the gypsum sintering to 170℃ resulting in gypsum which can be used for painting the ceiling, wood; if it is to burn 750℃ and crushed into powder which can make anhydrite, used to manufacture printing floors, window frames, windowsills, stairs, etc; heated to 150℃, off crystalline water two ripe gypsum, after a powder mixed with water can turn into a slurry plasticity which is the artist’s ideal material for sculpture, at the same time, by adding the gel fibers lime and other objects, then inject portrait mold, the mold is opened to be a variety of lifelike statue after a few hours.
Gypsum has good fire resistance, effectively guarantee the safety of the building, long and short material properties help regulate indoor humidity; when the indoor is humidity, these pore water can be inhaled; and vice versa.
In recent years, the rise of real estate industry, drive consumption growth in the construction industry. Gypsum powder has a pivotal role on the development of construction industry, grinding mills and gypsum processing equipment, only to meet the development needs of the mill industry in order to dominate the market, boosting the development of advanced equipment industry.

1, Raymond Mill, HC series pendulum grinding mill: low investment costs, high capacity, low energy consumption, equipment stability, low noise; is the ideal equipment for wollastonite powder processing. But the degree of large-scale is relatively lower compared to vertical grinding mill.
2, HLM vertical mill: large-scale equipment, high capacity, to meet the large-scale production demand. Product has high degree of spherical, better quality, but the investment cost is higher.
3, HCH ultrafine grinding roller mill:ultrafine grinding roller mill is efficient, energy-saving, economical and practical milling equipment for ultrafine powder over 600 meshes.
4, HLMX ultra-fine vertical mill: especially for large-scale production capacity ultrafine powder over 600 meshes, or customer who has higher requirements on powder particle form, HLMX ultrafine vertical mill is the best choice.
Phrase one: raw material crushing
Gypsum blocks will be crushed to 15mm-50mm fineness by crusher.
Phrase two: grinding
Crushed gypsum will be sent to the storage hopper by the elevator, and then the feeder will send the material to the main mill for grinding.
Phrase three: classifying
Grinded gypsum powder will be classified; coarse powder will fall back into the main mill waiting to be grinded again.
Phase four: production collecting
qualified powder will flow with the air and be collected in the dust catcher, and then the finished powder will be transported to the product storage bin through discharge port. Lastly, the powder will be loaded by tank car or packed by packing machine.
