How Calcium carbonate special dryer works
Calcium carbonate special dryer, also known as calcium carbonate disc continuous dryer, is mainly used for drying materials with a certain humidity and particle size range, widely used in building materials, metallurgy, chemical industry, quartz sand, mineral powder, calcium carbonate, coal powder, pigments, dyes , pesticides, medicines and various metal concentrates, tailings and other loose materials drying. After years of research and development and industrial testing, Gongda Company has made the calcium carbonate dryer with the advantages of energy saving, environmental protection and airtightness.
Calcium carbonate special dryer is a basic raw material in chemical industry production, including heavy calcium carbonate, light calcium carbonate, activated calcium carbonate and nano-scale calcium carbonate. It is widely used in the fields of rubber, plastic, paper, paint, medicine and health care and pesticide production. It is an ideal chemical production filler. The finished product made of light calcium carbonate as filler is waterproof, insulating, beautiful, lightweight, strong Durable, smooth net high unique performance and high quality. With the current economic development and the background of the country building an energy-saving and environmentally friendly society, the market demand for light calcium carbonate is increasing year by year, and the requirements for the production of light calcium carbonate are also increasing. Product consumption and environmental protection of production have put forward new requirements in the new era.
The wet material is continuously fed from the feeder to the first drying plate of the upper part of the Calcium carbonate special dryer, and the rake arm with the rake blade makes a rotary motion to make the rake blade continuously turn over the material. The material flows along the surface of the drying tray along the exponential spiral, the material on the small drying tray is moved to the outer edge, and falls to the outer edge of the large drying tray below, on the large drying tray, the material moves inward and falls from the middle. The spout falls into the next layer of small drying trays. The large and small drying trays are arranged alternately up and down, so that the material can flow through the entire dryer continuously. The heating medium is passed into the hollow drying pan, and the heating medium is in the form of saturated steam, hot water and heat-conducting oil. The heating medium enters from one end of the drying pan and is exported from the other end. The dried material falls from the last layer of drying tray to the bottom layer of the shell, and is finally moved by the rakes to the discharge port for discharge. The moisture escapes from the material and is discharged from the moisture outlet on the top cover, and the moisture in the Calcium carbonate special dryer is extracted from the vacuum pump on the top cover. The dry material discharged from the bottom layer can be packed directly. By adding auxiliary machines such as fin heater, solvent recovery condenser, bag filter, dry material back-mixing mechanism, induced draft fan, etc., its drying production capacity can be improved. Calcium carbonate special dryer is used to dry paste paste and heat-sensitive materials. The solvent can be easily recovered, and the pyrolysis and reaction operations can be carried out.
