Spiroflow helps WRG waste recycling in Sheffield

Every week 280 sacks were manually unloaded one at time and transported in a barrow to a storage area around a hoist.
The manual hoist, which took two men to operate, was used to transfer sacks to a third floor where they were stored ready to be discharged into the grist mill - the start of the brewing process.
During 2001, the malt supplier switched to 25 kg sacks meaning that, each week, 560 sacks had to be hoisted up to the mill! This operation was effectively taking a full man week to meet the requirements of nine brews a week.

Also, it tied up the delivery truck for a whole morning! In September 2001, a 'Spiroflow' Aero-Mechanical Conveyor, with integral sack tip hopper, replaced the hoist.
The conveyor, which has 80 mm diameter conveying tubes, is 9 metres long, operates vertically with the drive motor at the top.
Today, 25kg sacks of malt are delivered on pallets, unloaded by fork lift in half an hour and stored in a new warehouse across from the brew house.
They are taken to the conveyor by electric pallet truck.
Sacks are emptied in to the conveyor at ground floor level at a rate commensurate with the performance of the grist mill.
An alarm in the mill feed hopper warns the operator if he is emptying sacks more quickly than the mill can accommodate.
Head brewer, Bill Wilson, confirms "We prefer to use sacks as, that way, it is easy to control the weight of ingredients for each brew.
One of the many things we like about the 'Spiroflow' Aero-Mechanical Conveyor is that, what's put in at the bottom, comes out at the top.
There is no loss in the conveyor - essential to ensure each brew has the correct amount of each ingredient".
The malt required for every brew is now transferred to the grist mill hopper in around an hour.
Bill Wilson reports that the only maintenance on the Aero-Mechanical Conveyor has been an annual rope tension check.
Other than that, he confirms that the conveyor and the service provided by Spiroflow are, "As good as it gets".
Why an Aero-Mechanical Conveyor? Through his own research, Bill Wilson concluded that it was the cost effective solution compared to pneumatic conveying.
It achieves the same result at lower capital cost.
And, as there is no net displacement of air, no filtration equipment is required.
And why an Aero-Mechanical Conveyor from Spiroflow? Bill Wilson adds, "Because the Spiroflow response was the best.
In addition, we were able to take a sample of product to their test facility and prove first hand that they could achieve what we wanted".
