Quantitative relation between particle size distribution and ultrafine grinding process of ground calcium carbonate;

Ultrafine Ground Calcium Carbonate (GCC) is not only a high added-value product, but also a high quality and environment friendly filler.

The vertical miler mills applied to producing non-metallic minerals such as ground calcium carbonate,barite, pyrophyllite and others were discussed.

Optimized Parameters on the Process of TSP;

Research on TSP processing of Dayukou Phosphate Mine;

The main parameters of TSP produced by Slurry Process using Haikou phosphate rock (PR) in Yunnan province and the additives improving the cohesiveness of TSP produced by Den Process have been studied in this paper.

This paper relates the basic property of calcium carbonate which affects the processingperformance of rubber and mechanical properties of cured compound, and briefly introduces theapplication of heavy calcium、light calcium、active calcium and nano-calcium used in rubber goods.

This paper discusses the effects of ball material ratio, pulp density, and medium type on the grinding result, and provides the appropriate technical parameters for the preparation of ultrafine heavy calcium powder.

STUDY ON PREPARATION AND APPLICATION OF GCC ULTRAFINES;

Ground calcium carbonate (GCC) is one kind of ordinary non-metallic mineral materials.

The inorganic pigments or fillers, such as titanium pigment, GCC (ground calcium carbonate), talc or kaolin, are dispersed respectively in water with polycarboxylic salt as dispersant and(or) alkyl phenol polyethenoxy ether as wetting agent.

The paper report discussess the method in which extract directly available phosphorus from granular triple superphosphate and superphosphate with neutral ammonium citric acid.

The results indicate:2 μm heavy Calcium Carbonate have better proportionate modification effects on toughening and strengthening UPVC produces,and on rheological behavior than light Calcium.
