Application scope and effect:
This product mainly applies to composite cement, slag cement, fly ash cement and pozzuolanic cement. Applies to Portland cement and ordinary cement as well.
Applying to composite cement: when the water content of the mill feed materials is less than 2.0%, the grinding aid will not only increase the hour output of the mill, it will also reduce the consumption of clinker.
When the desired 45um fineness remains unchanged, the production will increase by 10%.
When desired strength and milling capacity remain unchanged, clinker consumption will be reduced by 6-10% , replaced by the same amount of blended material.
Similar effect will be obtained when the grinding aid is used in slag cement , fly ash cement and pozzuolanic cement.
The cement properties mixing with the grinding aid:
1. The fluidity of cement powder will increase.
2. The fluidity of mastic cement sand slightly increased.
3. The water consumption for standard consistency decreased slightly. ( same blended materials , same amount).
4. The setting time is lengthened 15-40 minutes.
5. The 45um residue of sieve is recommended to control discharge fineness, residue of sieve will decrease, at the same time the value of specific surface area does not increase.
Cement grinding aid is mainly used in cement plants , ore powder enterprises to aid grinding, increase production, save energy and lower the cost. Our company has researched and developed production of Jt - iit, Jt - dC, Jt - dC3, Jt - dC8, Jt - iiCs, of five series incl. more than 30 varieties. We provide personalized services for large cement plants and ore power enterprises at home and abroad. With the help of our technical service the cement production cost has reduced by 5-15 yuan/t. Among them, the "special grinding aid for composite cement of mass blending limestone ", "special grinding aid for 28 days cement strengthening " and "special grinding aid for vertical mill" have been appraised being reached the international leading level by science and technology departm
