Calcium carbonate is one of the most widely used inorganic fillers, which can be divided into two categories: heavy calcium and light calcium. The former is made of natural minerals (mainly limestone and calcite) after grinding, and the latter is obtained by chemical precipitation. With the development of technology, environmental protection and energy problems, sodium hexametaphosphate technical grade has become a grinding aid to improve grinding efficiency and reduce grinding energy consumption.

One of the reasons for the low output of heavy calcium is the lack of mature superfine grinding technology. Superfine grinding is a process of high energy consumption. How to reduce the energy consumption and improve the efficiency of superfine grinding is an urgent problem to be solved.

Then Chongqing Chuandong Chemical Group, the manufacturer of sodium hexametaphosphate technical grade, tells you that the use of grinding aid industrial grade sodium hexametaphosphate can improve grinding efficiency and reduce grinding energy consumption:

1. Sodium hexametaphosphate technical grade has obvious grinding effect on the ultrafine grinding of limestone, but not on the coarse grinding.

2. The grinding effect of sodium hexametaphosphate technical grade on fine grinding is related to grinding concentration. The higher grinding concentration, the more obvious grinding effect.

3. The grinding aid effect of industrial grade sodium hexametaphosphate is related to the type of mill and grinding medium. For the vertical mill with glass ball as grinding medium, the grinding aid effect is the best. When the grinding concentration is 5O%, the amount of industrial grade sodium hexametaphosphate and NO2C is 0.5kect and 0.4KG respectively, compared with the ball mill, when the particle size is the same, the grinding time can be reduced by 30% - 50% That is to say, grinding energy consumption can be saved by 30% - 50%.

Chongqing Chuandong Chemical Group, the manufacturer specializing in the production of sodium hexametaphosphate technical grade, uses the genuine raw materials made from the phosphate rock of our own fine phosphate mine through the thermal process to produce, with uniform particles, less impurities, better flow rate and less consumption.
