Get PriceThe influence of roller compaction processing
· As the roll compaction force increases the AE also increases Typically higher AE values are due to higher levels of cohesion or an increase in the particle size/density as larger/heaver particles are harder to lift and separate at low air velocities The improved particle packing exhibited in the bulk property tests is not indicative of higher levels of cohesion cohesive powders tend to have inefficient
