Formed in 1953, Francis Flower is a family business which has grown over 60 years to become a specialist in minerals management, storage and processing. Originally a quarrying and lime-burning business, Francis Flower now provides a range of high-quality powdered minerals, limestone powders, super-fine white marble powders and other products for the agricultural and construction industries, as well as paints, plastics, food and pharmaceutical manufacturers.

Lee Dursley, Plant Manager at Francis Flower said, “Following the successful application of Russell Finex equipment in our bag-filling line, we decided to employ a Russell sieving machine to screen selected silos of powder during tanker loading. It was important to find a solution that would be compact and mobile due to the nature of lifting into position above the tanker. The sieve also needed to meet the high capacity demands of tanker loading.”Francis Flower required a sieve capable of meeting the desired 30-minute loading time for a 28 tonne tanker. With its considerable screening capacity, the company was confident that the Russell Compact Sieve was the smart choice for this application.The 1200 mm diameter Russell Compact Sieve is applied between the loading silos and delivery tankers to screen the marble powder before it is shipped. However, to allow for easier connection and loading to each tanker, the sieve unit is transported and elevated into position above the tanker using a telescopic handler.

The Russell Compact Sieve range is used in various industries to remove oversized contamination from bulk powders and granulates. These industrial screeners are ideal for high-capacity screening where space is limited, or in instances where a mobile solution is necessary. The units fit neatly into production and filling lines to check-screen incoming or outgoing materials. An innovative design means these screeners are less than half the height of a traditional sieving machine, and a wide range of sizes and customizations are available to meet specific requirements.Mr Dursley continued, “The Russell sieve proved the ideal solution for our requirements. The unit is quick and easy to setup and transport into position when needed. It more than meets our required throughput, and the sieving accuracy allows us to ensure a consistent quality of powder for our customers.”
