Do not mix with any other product.
Below -20°C CHRYSO® AMA 30 L may form crystals. If crystallisation occurs agitate or store it at positive temperature until reconstituted.
Directions for use
Dosage: 0.2 to 0.6 kg/metric ton of material to be ground. The optimum dosage can be determined by industrial trials.
Do not mix with any other product. Below -20°C CHRYSO® AMA 30 L may form crystals. If crystallisation occurs agitate or store it at positive temperature until reconstituted.
Cleaning: Spillage of CHRYSO® AMA 30 L can be removed with water.
Warning: In certain circumstances, CHRYSO® AMA 30 L may cause an increase in air content. Trials should be conducted and air contents checked before full scale production is undertaken.
The quality is guaranteed for 12 months starting from the manufacturing date provided the product is not altered with other chemicals.
Grinding of cements according to EN 197-1, type I to V, and aluminous cements.
Dosages in excess of 1 Kg/ metric tonne should be avoided.
A dosing pump is required to introduce the correct dosage into the mill.
CHRYSO® AMA 30 L may be introduced directly into the mill or on to the feed conveyor belt.

- Increased 28 day mechanical strengths of the cement (from 10% -15% at equal composition).
- Allows for limestone extension and therefore decreases the percentage of clinker in cement in order to reduce CO2 emissions and production costs.
- Increased mill production (10% to 25%) depending on the efficiency of the equipment and the characteristics of the material to be ground.
- Reduced grinding energy costs.
- The mechanical strength of cement is maintained or increased during the early stages.
- Improved physical properties of the ground material.
- Improved efficiency in closed circuit systems, at equal specific surface area or equal sieve residues. This is due to the prevention of cement agglomeration in media, diaphragms and liners.
- As the agglomeration of the grinded particles is eliminated, the separator return is significantly reduced, improving efficiency.
- The bulk density of cement is increased and powder flow characteristics are improved before, during and after storage.
- A reduction in setting times, pack set tendencies and coatings.
