Calcium carbonate is the most commonly used abrasive in ordinary toothpaste. This is because the calcium carbonate resource is very rich, which makes its price relatively low, and it is an economical and cheap toothpaste abrasive. So, what are the requirements for calcium carbonate for toothpaste? What grinding equipment is used to produce calcium carbonate for toothpaste? As a calcium carbonate mill production line manufacturer, the calcium carbonate grinding mill produced by HCMilling(Guilin Hongcheng) has been widely used and has a good reputation among toothpaste calcium carbonate manufacturers. The following is a detailed introduction to the requirements and production equipment of calcium carbonate for toothpaste.
Calcium carbonate used as a toothpaste abrasive is divided into two types: precipitated calcium carbonate and natural calcium carbonate. The synthesis process of precipitated calcium carbonate has some difficult problems: (1) the reaction is not complete; (2) the pH value of the synthesized product is too high, which is not conducive to preservation and oral health; (3) the raw material is not completely calcined, which makes the product easy to Contains sulfides that make toothpaste very susceptible to spoilage. For these reasons, there are basically no manufacturers at home and abroad that use precipitated calcium carbonate as a toothpaste abrasive. Natural calcium carbonate is a heavy calcium carbonate made by directly grinding natural ore, shells and other materials through a calcium carbonate mill. The natural calcium carbonate used as toothpaste abrasive mainly includes calcite and dolomite. Their main components are calcium carbonate. The main production process is to grind the raw materials to more than 400 mesh (about 38μm), and then dry. The main disadvantages of using natural calcium carbonate as a toothpaste abrasive are: (1) The Mohs hardness of natural calcium carbonate is about 5.0, and the powder after grinding still has sharp edges and corners, which is easy to cause obvious damage to the user’s teeth after long-term use. Abrasion; (2) Fluoride cannot be added to toothpaste using calcium carbonate as abrasive. The main advantages of natural calcium carbonate used as a toothpaste abrasive are: (1) rich in resources and low price; (2) in addition to fluoride, it can maintain good compatibility with other active components.
Therefore, what kind of equipment can be used to produce 400 mesh calcium carbonate powder for toothpaste? HCMilling(Guilin Hongcheng) has HCH series calcium carbonate ultrafine ring roller mill and HLMX series calcium carbonate ultra-fine vertical roller mill for your choice. Its grinding range is 325-2500 mesh. Among them, the HCH ring roller mill is more economical in price, but the output and later maintenance costs are high, so now larger enterprises have gradually eliminated the ring roller mill and selected the HLMX series ultra-fine vertical mill for the production of calcium carbonate for toothpaste.
