On June 1, GB175-2023 "General purpose Portland Cement" was officially implemented. The new national standard not only puts forward more stringent and detailed requirements for the strength, fineness and composition of cement, but also standardizes the type of mixed materials used, and the cement production standard has been improved again.
The new national standard stipulates that the minimum content of clinker + gypsum in P.O42.5 cement is 80%, which increases the proportion of clinker, and the provisions on the components are also more refined, regulating the use of mixed materials. The implementation of the new national standard will lead to an increase in the production cost of most cement enterprises, which is expected to rise by 10 to 20 yuan/ton. Recently, production enterprises have begun to produce new national standard products, and cement prices across the country have also risen in stages.
In the long run, the implementation of the new national standard of cement will further accelerate the integration of enterprises, improve the concentration of cement production capacity, help accelerate the survival of the fittest in the cement industry, and promote the high-quality development of the industry. At present, the focus of cement enterprises is how to control costs while improving production efficiency, energy saving and emission reduction, to achieve win-win economic and environmental benefits.
Cement grinding is a link in the process of cement production with high energy consumption. The addition of cement grinding aid in the grinding process can significantly improve the output of cement bed and the strength of cement at each age, and can play a role in aiding grinding and reducing the agglomeration of cement particles in cement grinding and conveying equipment, speeding up the flow of cement in the production system, so as to achieve the effect of energy saving and emission reduction.
With the increasingly fierce competition in the cement market, how to reduce the cost of cement production is a problem that major cement enterprises must seriously think about, and the successful application of cement grinding aid has undoubtedly brought an effective way to reduce the cost of cement production. How to use grinding aid and what kind of grinding aid can maximize the cement benefit is a problem that cannot be solved in the market.
In order to further improve the quality of cement and better reduce cost and increase efficiency for cement enterprises, Shandong Runchang Building Materials Technology Co., LTD., with the implementation of the new national standard, has launched P.O special grinding aid, P.C special grinding aid, 32.5 special grinding aid, among which:
P.O special yield type yield increase 15-25%,
P.O post-strong 28-day increase of 5-8 mpa, 3 days can also synchronously increase 4-6 mpa,
P.C early strength grinding aid early strength increased by 4-6 mpa, compound yield increased by more than 15%,
3 days 28 days simultaneous growth of 4-6 mpa,
And 32.5 special grinding aid series of exclusive products,
Can also be tailored to customer needs to create exclusive grinding aid.
A new product developed by the company can replace the effect of the two grinding AIDS used by the original customer, and the comprehensive cost of annual output of 500,000 tons of cement can be reduced by 12.75 million yuan!
The following is the product comparison analysis table:
Company product profile:
01 Efficient grinding aid
This product is suitable for all kinds and strength grades of cement in line with general Portland cement standards. It can effectively improve the working conditions in the mill, optimize the cement particle composition, improve the grinding efficiency, and increase the output of the mill by 15%-25%.
Blank cement foundation increased by 4-6 mpa in 3 days and by 4-6 mpa in 28 days; It can save more than 8 percentage points of clinker, and the cost of a ton of cement can be reduced by 15-30 yuan.
02 Mother liquor of grinding aid
1, liquid grinding aid mother liquid: suitable for a variety of cement mixtures and grades of cement, can also be customized according to different clinker mixtures in each customer area, improve the use of efficiency. In the case of the same cement ratio, on the basis of blank cement 3 days to increase 3-6 mpa, 28 days to increase 5-10 mpa, cement quality unchanged, increase the mixing material 6-10 percentage points, improve the machine output 10%-20%.
2. Mother liquor of powder grinding aid: It mainly improves the three-day strength of cement. For various cement raw materials, it has good adaptability, obvious grinding aid and strengthening effect, and can effectively increase the output of the stage on the basis of the original cement ratio and the addition of liquid grinding aid, so that the cement particles of 3-32um are increased and the particle size is reduced during the cement grinding process, and the gradation of cement particles is optimized, so as to achieve higher yield and improve the early and late strength of cement.
