100 years and still improving – The Move to High Performance Mixing

2019 is our centenary year. Over the past 100 years, Greaves has built an enviable reputation for our knowledge and expertise in mixing processes and systems. While the technologies have continually developed to meet the growing needs and expectations of our customers, we have witnessed a significant acceleration in the sophistication of mixing requirements over the past 20 years.

Above all, with market forces driving a relentless pursuit of product quality and consistency, our clients have been pressed to constantly improve their manufacturing processes. As a result, enhanced technical performance and mixing productivity are now essential. These advances have primarily been achieved through process systems delivering ever more flexible control automation and a corresponding reduction in the need for human intervention.

In today’s manufacturing world, the Greaves Team sees a constant requirement for High-Performance Mixing Solutions and Integrated Mixing Systems. Furthermore, we have seen this shift across all of our markets whether industrial chemicals, food or pharmaceuticals.

Examples of 21st Century integrated mixing systems from Greaves

Consequently, many features that might have been considered as optional ‘add-ons’ or costly luxuries in the 1980s and 90s are now common requirements:

  • Hygienic design with no “hang-ups” to avoid cross-contamination
  • Highly-polished stainless steel
  • Integrated cleaning systems for rapid product change
  • Rapid heating and cooling for energy efficiency
  • Pressurised/vacuum vessels to control cycle times
  • High-performance shaft sealing technology to eliminate product leakage
  • Automated filling and discharge to expedite production turnaround
  • Programmable cycle control with batch recording for end-to-end traceability
  • Material and finish certification, FAT & SAT acceptance for comprehensive documentation

Notwithstanding these rapid changes, we are proud to maintain our position at the forefront of industrial mixing technology.

So, here’s to the next 100 years.

Greaves Solution: Capacity Up 660%

Borregaard are an innovative additive producer servicing a wide range manufacturing industries including Construction, Agriculture, Animal Feed, Oil & Gas, Food and Pharmaceutical.

The single largest use for lignosulfonates is as plasticisers in making
concrete, blocks and bricks

Borregaard is the leading UK manufacturer and distributor of Lignosulphanates.

Lignosulphanates are widely used in construction products to increase manufacturing efficiency, reduce energy usage and improve product performance.

Project Brief:

Borregaard UK Production Manager, Chris Barrick takes up the story…

“To meet increased demand and to improve efficiencies, we needed to rapidly increase our production capacity and turned to Greaves for help. Our manufacturing process is very challenging as it includes the dispersion of a fine, hygroscopic powder in liquid.  Process time for large batches was often upwards of two days from start to finish and required a significant amount of operator input.”

Chris invited Greaves to study the companies existing production set-up and offer alternative solutions.

The Greaves Proposition...
Greaves technicians conducted a thorough process review and proposed a change in mixing technology using Borregaard’s existing process vessels. The next step was to perform small-scale trials in Greaves MixLab R&D centre. The trials confirmed the suitability of the new technology which gave Borregaard confidence to invest in Greaves full-scale solution.
The Results...

The first two Greaves mixers were installed in Borregaards existing 5000L & 24000L vessels and had an immediate impact on operations.

Chris Barrick continues: ” This has resulted in improved efficiencies for operators and production output.  We are now able to produce 5 times more product in our larger process and 10 times more product in our smaller process over the same period of time as previous methods of mixing technology had produced.

We are extremely pleased with the outcome and would like to thank the team at Greaves Mixers for helping us to achieve this significant step forward in our production efficiencies and capacity.”

Project Update...

The Borregaard parent company has been so pleased with the commercial success of this new technology that they have now made funds available for investment in 3 new vessels and mixers.

Greaves is delighted to work with Borregaard and its team and we look forward to assisting their future growth.
