Talc powder is prepared by talc grinding mill machine. Talc is one of the minerals. It is buried underground with serpentinite containing asbestos, so it often contains asbestos in its natural form. The possibility of asbestos in medical talc powder has been widely disputed in recent years. The first problem faced by talc powder in medical treatment is the safety problem. Now, medical talc powder has a special production process to ensure medical safety. As a professional manufacturer of talc powder Raymond mill, HCMilling(Guilin Hongcheng) will discuss with you the production of medical talc powder and the application of talc powder Raymond mill.

How to judge whether talc powder is medical? Medical talc powder has many effects, such as clearing heat, seeping moisture, benefiting the orifices, curing heat and thirst, bad urination, diarrhea, dysentery, gonorrhea, jaundice, edema, bleeding, beriberiberi, and wet skin. Soluble matter in acid is an important indicator of medical talc powder. Relevant data show that the soluble matter in acid of many medical talc powder sold on the market exceeds 2.0% of that prescribed by the Chinese Pharmacopoeia. It is an important reference to ensure that medical talc powder does not contain asbestos. Generally, the preparation of medical talc powder with talc as raw material is mainly realized through process combination.

Production process of medical talc powder: firstly, raw talc ore is processed into coarse talc powder by talc grinding mill, with a fineness of about 325 mesh; Then, magnetic separation and impurity removal. The crude talc powder is added with water to prepare the slurry, and an appropriate amount of sodium silicate is added. After mixing, the talc powder is sent into the weak magnetic separator at a certain feeding speed, and impurities are removed under a certain magnetic field strength; Then it is acid cleaning. Mix the magnetically separated talc powder with appropriate amount of water, mix the slurry and hydrochloric acid with 20% mass concentration of 10-30% crude talc powder, stir evenly until no bubbles are produced on the liquid surface, filter, wash with water until the washing solution is neutral, and then flotation refining; Add proper amount of water to the acid-washed talc powder to prepare the pulp, add the pulp and the flotation mixture with 0.03-0.2% mass ratio of crude talc powder into the pulp mixing drum for mixing, and then add the pulp into the flotation tank for flotation; Finally, the selected refined products were washed, filtered and dried, and finally the medicinal grade talc powder was obtained.
