Plastics and polymer compounding uses powders, granules and additives that must be mixed uniformly and screened before extrusion or moulding. Masterbatches and PVC compounds need intensive mixing to disperse pigments and additives.
We supply mixing and screening equipment for polymer powders, compounds and recycled material.
Process challenges
Additive dispersion: small quantities of stabilisers, pigments and fillers must be evenly mixed.
Static and light particles that segregate or form dust.
Oversize and contamination that must be removed before processing.
How we solve them
We supply plough shear mixers for intensive mixing of powders and additives, sigma mixers for doughs and viscous compounds, and vibro sifters and gyro screens for screening granules and powders.
Typical process flow
Weighing
Resin and additives are weighed.
Mixing
Ingredients are mixed until additives are evenly dispersed.
