When farleygreene were asked to provide a sack tipping system to sieve powder prior to loading into road tankers there were a number of criteria that needed to be met.
A predeturmined time scale was necessary to ensure that the tankers were filled at a rate of 6 tonnes per hour.
Manual sack tipping was required, as the material was only available in 25 kg bags.
The road tanker had to be filled via a number of access ways within the top of the tanker.
The client, already using Farleygreene Sievmaster equipment within his plant, put the problem to Farleygreene to see what possible methods were available within their budget.
As with all customer requirements Farleygreene are ever conscious of the need to provide cost effective solutions. Approaching each facet of the problem individually, analysing the requirement and using their vast wealth of experience in solving customers material handling and sieving problems a consept of the design was produced.
After carrying out material throughput trials, at Farleygreenes test facility in Aldershot, it was ascertained that the Sievmaster Slimline 950 unit could adequately provide sufficient throughput. The machine would also easily locate within a sack tip arrangement without the need for complicated structures. Was of total stainless steel construction and met all the food requirements of the client However two bag tipping operators were required to adequately feed the powder at the necessary supply rate. A double back to back sack tip station was designed. this allowed each operator free access to discharge product into the single sieve area. They had separate areas to work in and there was no risk of them overlapping.
To elevate the product to the desired height and position created a further problem, discharge location could not be guaranteed as each tanker had different inlet ports and location was always slightly different dependant upon the parking position of the tanker. In addition it was essential that the dust, during the loading, was contained. A vacuum loading system was the obvious choice. By locating a vacuum hopper loader onto a multi-directional wheeled runner, mounted within a track fixed to the building, it was possible to position the hopper loader exactly over any of the inlet ports of any size tanker. An access way allowed an operator to position the hopper loader, and easily locate the dust retaining sleeve arrangement. The hopper could be easily moved from one inlet port to the next with the minimum of effort, without danger to the operative and in the minimum of time scale all allowing for fast loading.
To draw the sieved material into the vacuum system a static receiving hopper was located at the discharge of the sieve funnel, connected via an FDA approved connecting sleeve and thence the vacuum flow drawing the material into a swept elbow and away to the hopper loader for discharge.
The entire system was engineered to be completely dismantled without the need of mechanical tools, each connection being fitted with quick release clamps or connectors. The system was easy to operate, and provided a simple, cost effective and adaptable solution to what had originally been thought to be a complicated and expensive requirement.
Another simple solution, meeting the customers needs with a cost effective, efficient and reliable design from Farleygreene.
If you have a sieving requirement, whether it be a simple sieve or the need for a more objectively designed solution talk to Farleygreene for advice.
