Disc Dryer for Calcium Carbonate

Disc Dryer for Calcium Carbonate

Calcium carbonate is an inorganic compound, commonly known as grey stone. Calcium carbonate disc dryer working principle is that the wet material from the feeder continuously added to the dryer on the first layer of the upper drying disc, with the rake leaf rake arm for the rotary movement so that the rake arm for the rotary movement so that the rake leaf continuously flipping the material.

Calcium Carbonate Materials

Calcium carbonate is an inorganic compound commonly known as chert, limestone, stone dust, marble, calcite, a compound with the chemical formula CaCO3, which is alkaline, essentially insoluble in water and soluble in acids. It is a common substance on Earth, found within rocks such as aragonite, calcite, chalk, limestone, marble, and travertine. It is also a major component of animal bones or shells. Calcium carbonate is an important building material with a wide range of industrial uses.

The role and use of calcium carbonate materials

1.Determination and determination of halogens in organic chemical reactions. Water analysis. Determination of phosphorus. Decompose silicate with ammonium chloride. Preparation of calcium chloride solution to standardise soap. Manufacture of optical neodymium glass raw materials, paint raw materials.
2. It can be used as additive in food industry.
3. It can be used as calcium supplement.
4. Commonly used in construction and paper industry.

Calcium carbonate disc dryer working principle

The wet material is continuously added to the first layer of drying disc on the upper part of the drier from the feeder, and the rake arm with rake leaves makes rotary movement so that the rake arm makes rotary movement so that the rake leaves continuously turn over the material. The material flows through the surface of the drying disc along the index helix, and the material on the small drying disc is moved to the outer edge, and falls to the outer edge of the large drying disc below the outer edge of the large drying disc, and the material on the large drying disc moves inwardly and falls down to the next layer of small drying discs from the middle of the material falling mouth. The size of the drying discs arranged alternately up and down, the material to flow continuously through the entire dryer. The hollow drying disc passes into the heating medium, the form of heating medium has saturated steam, hot water and heat-conducting oil, the heating medium enters from one end of the drying disc, and leads out from the other end. The dried material falls from the latter drying disc to the bottom of the shell, and then is moved to the discharge port by the rake leaves and discharged. Moisture escapes from the material and is discharged from the moisture discharge port located on the top cover, and the moisture of the vacuum-type disc dryer is discharged from the vacuum pump port located on the top cover. The dry material discharged from the bottom can be packed directly. By adding fin heater, solvent recovery condenser, bag-type dust collector, dry material re-mixing mechanism, induced draft fan and other auxiliary machines, it can improve its drying production capacity, drying paste and heat-sensitive materials, it can be convenient to recover solvents, and it can carry out pyrolysis and reaction operations.
