Blending

The following processes are available in many of the 13 self-contained process units in our Crewe factory:
3 Low shear batch blending units.
4 High shear batch blending units.
3 Continuous blending systems.
1 Fluidised bed system.

Low shear blending is offered using ribbon and U Trough blending equipment. These blenders achieve a gentle folding action with blend times typically 20 to 60 minutes.
Feed to the blenders can be from big bags, sacks, drums or boxes. Feed material can be check screened prior to charging into the blender.
Product is typically discharged to big bags but can also be packed to sacks or boxes incorporating check screens.
With careful operation these blenders can disperse oils and waxes onto powder or granules in order to reduce the dustiness of the final product.
High shear Ploughshare mixers are available with capacities ranging from 2000 to 4200 litres. They are capable of the accurate dispersion of low levels of chemicals in short blend times.
Chopper units (running between the ploughs) permit dispersion of liquids into the blend and also serve to control oversize generation should this be an issue.
Very high shear blending can uniformly disperse high viscosity liquids into powders with heating if required.
Custom Powders in house designed loss in weight systems can continuously blend up to 4 powder streams and a liquid if required.
