Conveying and Feeding of Calcium Carbonate in Plastics Compounding
The design of a feeding or
pneumatic conveying system
is heavily influenced by a bulk
solid’s particle shape, size (aspect ratio) and particle size distribution as well as the particle’s
roughness, hardness (abrasiveness), and density.
In the case of calcium carbonate these characteristics vary
widely depending on the source
and production process for the
individual samples. The sieve
analysis below illustrates the
difference in particle shape,
particle size and particle size
distribution for two samples of
calcium carbonate.
