Using sodium hexametaphosphate technical grade to improve grinding efficiency and reduce grinding energy consumption

 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.

The manufacturer tells you the dispersing effect of sodium hexametaphosphate

The dispersing effect of sodium hexametaphosphate is due to its hydrolyzed anions adsorbed on the particle surface. In order to improve the dispersing effect, the hydrolysis degree of the dispersant can be selectively increased. It is believed that we all know that the function of dispersant is to increase the distance between the large particles to be dispersed in the solution and reduce the viscosity of the whole solution. However, the amount of   sodium hexametaphosphate   used in the dispersion of different substances is also different. In the process of material dispersion, the surface of large particles adsorbs the dispersant to form a double electric layer, and anions are closely adsorbed on the surface of particles, which is called surface ions. Ions with opposite charges in the medium are called anti ions. In the process of medium movement, particles and particles, as well as the electric double layer and the electric double layer have the same charge, which will generate elec

Non-antibiotic growth promoter potassium diformate helps pig industry return to its essence

  The high profitability of the pig industry will not last, and the future development of the industry still needs to return to the essence of pig raising. The non-antibiotic growth-promoting agent   potassium diformate  helps return to the essence of breeding and helps control the cost and quality of the pig industry. Biosecurity has become the access condition of today's pig industry. Potassium diformate has the following functions and functions to return the essence of pig farming to the breeding industry: (1) Adjust the palatability of feed and increase animal feed intake. (2) Improve the environment of the animal's digestive tract and lower the pH of the stomach and small intestine. (3) It has anti-bacterial and growth-promoting effects. The addition of potassium diformate can significantly reduce the content of anaerobic bacteria, Lactobacillus, Escherichia coli and Salmonella in each segment of the digestive tract. Improve the resistance of animals to diseases and reduce

The factory tells you food grade sodium tripolyphosphate/STPP requires heavy metal purification

Condiments, meat products, edible oil, dairy products, drinks, etc. are all necessities of daily life. Some food additives will be used in the production and processing process. The use of additives also makes people more concerned about "safety on the tip of the tongue".  Sodium tripolyphosphate/STPP  is widely used in food additives. Chongqing Chuandong Chemical Group will show you the main applications of sodium tripolyphosphate/STPP in the food industry: 1. Food grade sodium tripolyphosphate is used in meat products, fish sausage, ham, etc., which can improve the water holding capacity, increase the cohesiveness and prevent fat oxidation; 2. For fruit drinks and cool drinks, it can improve the juice yield, increase the viscosity and inhibit the decomposition of vitamin C. 3. It can prevent discoloration, increase viscosity, shorten fermentation period and adjust taste when used in soybean paste and soy sauce. 4. For ice cream, it can improve the expansion capacity, increa
