We can blend powders in batches from 50kg to 1,500kg using a ribbon blender or nautamixer.

With a batch size of 50kg to 1000kg, depending on bulk density, impregnated or coated granules can be produced in a rotary drum blender.

Raw materials are input from kegs, sacks or FIBCs and liquids can be added if required. The addition of liquids is achieved by spray nozzles with air micronisation if required, while inter-process transfer is achieved by the ‘tote’ bin system.

We can pack container sizes from 50g to 1000kg with high-fill accuracy. We can also pack kegs, drums and sacks up to 25kg. The packing of smaller items includes –

– Laminate block bottom bags filled on automatic or semi auto lines

Product Development

Grotech offer development and analytical services to help you reach your formulation and production goals.

Investment in analytical equipment and expertise in analysis methods allow quick assaying of your products and screening of your raw materials, from which we can produce certificates of analysis that you and your customers can trust.

We can help you develop emulsifiable concentrates, liquids, emulsions and powder blends.

Where you have an existing product, which does everything you want on the field, but is awkward to handle due to flow, dustiness, volatility, viscosity etc, then we can help you to tweak your formulations until they are exactly how you want them to be. Let us help you to solve your problem.
