Special disc dryer for calcium carbonate

Calcium carbonate is a kind of inorganic compound, commonly known as Gray stone. Calcium carbonate Special Disc dryer working principle is the wet material from the feeder continuously added to the top of the dryer on the first layer of drying disk, with rake blade rake arm for the rotary movement so that the rake arm for the rotation of the rake leaves continuously to copy material.

Brief introduction of calcium carbonate materials

Calcium carbonate is an inorganic compound, commonly known as Gray stone, limestone, stone powder, marble, calcite, is a compound, chemical formula is CaCO3, alkaline, basically insoluble in water, dissolved in acid. It is a common substance on earth, in the presence of Yu Shi, calcite, chalk, limestone, marble, travertine and other rocks. It is also the main ingredient of animal skeleton or shell. Calcium carbonate is an important building material and is widely used in industry.

function and use of calcium carbonate materials

1. Characterization and determination of halogens in organic compounds. Water analysis. Verification of phosphorus. The silicate is decomposed together with ammonium chloride. Preparation of calcium chloride solution to label the soap liquid. Manufacturing optical nd glass raw materials, paint raw materials.
2. Can be used as an additive in the food industry.
3. Can be used as calcium supplement.
4. Often used in construction and paper industry.

Working principle of special disc dryer for calcium carbonate

The wet material self-feeder is continuously added to the first drying disk on the top of the dryer, and a rake arm with rake leaves is used for turning movement so that the rake leaves are continuously copied material. The material along the exponential spiral flow through the surface of the drying plate, the material on the small drying plate is transferred to the outer Rim, and the outer rim falls to the outer rim of the large drying plate, the material moves in the big plate and the falling material from the bottom of the following layer of small drying plate. The size of the drying plate alternating up and down, the material can continuously flow through the dryer. In the hollow drying disk into the heating medium, the form of heating medium saturated steam, hot water and heat conduction oil, heating medium by one end of the drying plate into the other end of the export. Dry material from
the last layer of drying disk fell to the bottom of the shell, and finally by the rake leaves transferred to the discharge port. The wet part escapes from the material and is discharged by a wet vent located on the top cover, and the humidity of the vacuum disc dryer is discharged by the vacuum pump port located on the top cover. Dry material discharged from the bottom can be packaged directly. By adding fin heater, solvent recovery condenser, bag filter, dry material return mixing mechanism, fan and other auxiliary machine, can improve its dry production capacity, dry paste and heat sensitive materials, can easily recover solvents, and can be pyrolysis and reaction operations.
