The invention discloses a system and a method for producing calcium carbonate dry powder. Compared with the prior art, the system comprises a drying and back mixing stirrer, a drying and scattering machine, a drying and scattering dust remover, a dust remover discharging screw conveyor and a comprehensive tank, wherein the drying and scattering machine is connected with the drying and back mixingstirrer; the drying and scattering dust remover is connected with the drying and scattering machine; the dust remover discharging screw conveyor is connected with the drying and scattering dust remover; the comprehensive tank is connected with the dust remover discharging screw conveyor; the comprehensive tank is connected with the drying and back mixing stirrer. Compared with the prior art, according to the system for producing the calcium carbonate dry powder, provided by the invention, produced calcium carbonate powder is higher in quality, the processing fluidity of a calcium carbonate material is favorably increased, and the comprehensive quality of the calcium carbonate material is increased, so that the production stability and the product quality of an air-permeable membrane are increased. The invention also provides a method for producing the calcium carbonate dry powder. The method provided by the invention has the beneficial effects.
Description
Technical field [0001] This application relates to the technical field of calcium carbonate preparation technology, and more specifically, to a production system for calcium carbonate dry powder, and the application also relates to a method for producing calcium carbonate dry powder. Background technique [0002] Calcium carbonate is an inorganic filler with a very wide range of applications. It can be widely used in industrial fields such as papermaking, rubber, building materials, coatings, inks, plastic products, cosmetics, and medicine. [0003] At present, breathable membrane materials can be bonded and laminated with knitted fabrics, woven fabrics, non-woven materials, etc., so that the fabrics can obtain special properties, and they are widely used in many fields. [0004] Among them, calcium carbonate material can be added to the breathable membrane as a breathable material. It is one of the very important components in the production and processing of the breathable membrane...
