Exwold

To support aggressive growth plans and a desire to increase their granule production and manipulation technology, Exwold have invested in roll compaction technology to bolster their portfolio.

They have purchased the plant and ancillaries which is worth £750,000 and have installed it at their Brenda Road site in Hartlepool, UK.

Roll compaction is not a new technology by any means but Exwold view it as an ideal way of producing high quality, lower cost granules to serve the global speciality chemicals market.

The technology works by means of very high pressures and produces a relatively dust free, free flowing granule from a powder feed material. No liquid addition or binders are required. It is a fully enclosed continuous system comprising recycling of fines and oversized particles.

The powder feed material is passed through two rollers under gravity which compress it under controlled high pressure into a flat 'ribbon' which is then milled into the desired granule size. These sizes can range from 0.5mm to 10mm.

Roll compaction is a very versatile granule production technique which lends itself well to a range of speciality chemical applications, such as flame retardants, de-icing products, water treatment products, animal feed additives and many more.

Speaking about the investment, Business Development Director, James Robson said,
'At Exwold, we are granule experts. We offer a specialist contract service to convert our client's products into granules. The benefits of converting products into granules are now widely endorsed by the speciality chemical and agrochemical industries. Their enthusiasm is driven by technical, commercial and environmental demands. The range of benefits offered by granules include improving flow characteristics, improved efficacy, controlling dust, uniform particle size range, controlling bulk density, uniform blends and controlling particle hardness. We researched the market for granules manufactured by roll compaction and concluded that it was a great fit for our portfolio. We're now looking forward to attracting more clients for this technology through our marketing activities'
