Ultrafine calcium carbonate powder is widely used in the paper making industry and plays an important role. Ultrafine mill is widely used in the processing of calcium carbonate.
The original purpose of paper making and fillering was to reduce the cost of paper. The main purpose now is to give paper some special properties. Due to the different purposes of filling, the proportion of fillers in paper varies greatly, generally between 10% and 20%. The use of a filler or several fillers depends on the particular properties of the paper required. Among all types of paper, printing paper and writing paper have the largest amount of filler. Fillers help to improve the following properties of paper:
1.Improve the formation and smoothness of the paper by filling the gaps in the paper sheet;
2.Increase the opacity and whiteness of the paper;
4.Increase dimensional stability;
5.Reduce the cost of paper.
Guilin Hengda Mining Machinery Co., Ltd is a professional grinding equipment manufacturer, HGM series ultrafine mill is a hot sell product. The specifications and features are as following:
HGM series ultrafine mill specifications:
Output size: 600-3000 mesh
Input size: ≤20 mm
