  Recycling
  A positive displacement pump to extract the sludge out of the centre of the thickener is then pumped across to a large sludge holding tank where two stirrers keep the silt in suspension. From here a twin centrifugal pump fills the press and when the filter press is full the system automatically switches from the centrifugal pump to a piston pump which uses significantly less energy than the centrifugal pump and contains no wear parts compared to the centrifugal pump hence an exceptionally low operational and maintenance cost.
When the water has filtered out of the cakes in the press then the pumps will stop and then the press will automatically open and discharge ten cakes at a time.
The Fraccaroli & Balzan (F&B)over beam filter press:
The Fraccaroli & Balzan overhead beam filter press at RMS offers so much more than other presses in the marketplace.
Fintan gave us the facts. “The Fraccaroli & Balzan overhead beam filter press at Dagenham has 210 - 2 x 2 metre square plates which is the largest over beam press installed in the UK Aggregate Recycling Industry!
“The key thing about this press is that the overhead beams sit to the side which allows full access to everything on the top; unlike traditional overhead beams where everything sits in the middle and include a chain drive mechanism and hooks on the chains to open the plates.
“Eventually all those hooks and the chain wear out and if you get a press ‘blow out’ sludge will cover all the mechanism making it extremely hard to access and maintain everything. On the F&B press, maintenance is super easy as everything sits to the side and there is full access round all sides of the press.”
Fintan, continued, “There is a robot mounted on top of the press which has three functions – it opens ten plates and then shakes them and discharges ten plates at a time which other overhead beams don’t do and also operates the automatic washing system which washes from the top down. This is completely different as alternate systems wash from the bottom up.
“It’s an extremely fast system and the only press in the country that has a completely flush floor so when the ‘bomb doors’ close up it is completely flush allowing you to actually walk through the plates making it extremely easy and safe to change the filter cloths, whereas on other presses it is more challenging to access everything.
“The whole system is automated, we have full remote access to all the control on the plant so if there are any alarms, operator problems or issues we can remotely dial into the plant and can access all the alarms and the history and can then offer advice to the plant operator as to what he needs to action.
“The whole design philosophy of this plant is making everything as easy as possible, easy to access, easy to maintain, easy to service which has been a total success.”
Remote access for the plant is from Tyrone and for the press, F&B in Italy.
Ensuring an effective plant on a daily basis:
The plant is fitted with a belt weigher to monitor the tonnage fed into the plant; additionally, remote data management can determine what time the plant started and stopped, including how many minutes the belt runs empty, what time the operator started to put material into the plant, which is basically to encourage better utilisation, better throughput of the plant.
All the components of the plant have been designed using top quality components that are available in the marketplace and all structures are galvanised, all paint is marine specification due to the location of the plant next to the Thames so the plant should be as good as it is now in five-years’ time.
“Delivered in the striking company red and white this state- of-the-art plant is something rather special and marks a significant step forward in plant design and Tyrone International are to be applauded for this versatile and efficient processing system, said John Edwards-Editor HUB-4”.
