Powder Processing

Power Blending

We are equipped to precisely blend multi-component powder products according to your specific requirements. We utilise a range of specialised blending machines to achieve this uniformity, including ribbon blenders, as well as ploughshare units fitted with refiner blades. Furthermore, the majority of our blending machines are fitted with pre-screening or sifting equipment, which ensures the final product is uniform and completely free from particles. We possess a wide range of blending capability, handling batch sizes from 25kg up to 4000kg.

Additionally, our capabilities extend beyond dry blending. We can integrate the process of spraying liquids onto powders, which is used to produce a highly free-flowing and agglomerate-free product.

Roll Compaction

We specialise in contract compaction, utilising advanced roll compaction technology to efficiently produce high-quality granules directly from your fine powder materials. As a superior dry granulation technique, this process delivers immediate operational and material advantages.

Core Benefits and Applications

Choosing our powder compacting service ensures a product that is dust-free and free-flowing, significantly improving handling efficiency and safety in your operations. Crucially, roll compaction requires no liquid additions or binders, making it the ideal choice for moisture-sensitive products or materials where solvent residue is a concern. We are committed to delivering competitively priced granules with superior quality.

This versatile technology is perfectly suited for a wide array of demanding speciality chemical applications, including:

• Flame Retardants

• De-icing Products

• Water Treatment Products

• Plastic Additives

Sieving

We provide expert services using various sieving equipment to achieve precise particle size separation. Through this process, we are able to separate both large and fine particles efficiently. A key capability is the use of two decks simultaneously, which allows for the efficient removal of any oversized material as well as fine (undersized) particles in a single operation. This processing technique is also commonly referred to as screening.

We use a comprehensive range of equipment types to suit different material characteristics and throughput requirements:

• Circular Sieves: We employ equipment such as those made by Algaier and Russell Finex.

• Rectangular Sieves: This includes machines manufactured by Locker.

• Sifters: We also utilize specialized sifters from providers like Powtek.

Packing

We are able to pack into containers of your choice, including bulk (FIBCs) or ‘big bags’, tote bins, drums, kegs, plastic containers or pails. We are also able to pack products into valve sacks, laminate bags, foil lined bags, multi-ply paper bags and plastic sacks. Our packing options range from 1kg to 1000kg.

We are able to offer 2-D Matrix labelling in compliance with crop market track and trace requirements.

Scaling up a mixing process can be a complex challenge influenced by a delicate balance of factors. Generally, applying more force to a mix reduces overall blending time, but this aggressive approach comes with trade-offs: it increases energy consumption, requires more complex and costly equipment, and significantly raises the risk of particle breakage or product degradation. To successfully navigate scale-up and maintain product quality, engineers rely on specific measurable metrics like tip speed and power per volume, alongside dimensionless variables such as the Reynolds, Power, and Froude numbers. While dimensional measurements are critical during the transition to larger batches, the Froude number is particularly valuable for characterising the underlying dynamics, allowing us to accurately predict whether a mixing regime will act as a gentle, low-impact blend or a highly aggressive, high-shear process.
