Blo-Tech Ltd, part of the Rotolok Group, are bulk material handling and pneumatic conveying system specialists. From product discharging – whether it be big-bag dischargers or silos – to product separation – whether it be cyclones, filter receivers or big-bag filling stations – Blo-Tech Ltd can incorporate a wide range of standard products supplied by the Rotolok Group or bespoke specially designed equipment to meet your bulk material handling requirements.
With a site survey to determine site constraints and conveying distances and with details of the product properties (which can be experimentally determined at the Rotolok Group Testing Facility at the Blo-Tech Ltd headquarters), Blo-Tech Ltd have experience of several conveying methods – including dense and lean phase pneumatic conveying and mechanical conveying – from which they can advise the most suitable option(s) for your specific needs, and then design the required system, including the associated access platforms and support frames.
A recent project saw Blo-Tech Ltd design a conveying system that decanted the customers product from their big-bags to a 7-tonne holding hopper which would be conveyed to a new sieve, that was three floors above. From this sieve, the oversized product was to be diverted to an existing hopper which would then decant into one of two existing mills. From the mills the product was to be conveyed back to the 7-tonne hopper recycling and adapting an existing conveying system for the customer to reduce their costs. The undersized product was diverted to a dust-free big-bag filling station, and the useful product diverted to one of two existing mixers.
To decant the big-bags a Solitec Engineering FIBC station with gantry was utilised. To convey the product from the 7-tonne hopper to the sieve a lean phase suction system was designed with a filter hopper as the separation method which was control-fed into the sieve via a Rotolok Ltd UK rotary valve. An inspection platform for the filter hopper was also designed to serve as the support frame of the sieve, which was independently verified for structural integrity and met platform and access standards. A Roots Systems Ltd exhauster was used to create the vacuum for conveying. A specially designed two-way Solitec Screw-feeder was implemented under the existing hopper to enable a choice of which mill the customer wanted to feed to. A standard Rotolok diverter valve was used for selecting which mixer the useful product from the sieve was sent to.
For clients that are worried product won’t convey pneumatically, the Rotolok Group Testing Facility based at the Blo-Tech Ltd headquarters can quench fears by physically running a sample of your product through a variety of mechanical and pneumatic systems.
