Internal cone silo without support columns A revolutionary new patent from Mulmix
Mulmix introduce a new patent for an internal cone silo that revolutionises the concept of the hopper silo by removing support columns. This is the important new product that Mulmix now offers its customers, especially those in the milling and animal feed sectors who require a mixed product from several silos on a daily basis.
Over the last year, the Mulmix R&D department has designed a revolutionary conical silo with a 45° hopper without support columns. It has a central free space inside that allows scales, feeders and chain conveyors that may be required to be placed under the cone itself. Aesthetically, it looks like a classic flat-bottomed silo.
'The special feature of this product is a unique system for fastening the cone to the silo. Depending on its use, the cone can be positioned at different heights from ground level according to the space required under the unloading hopper,' explains Andrea Nardo, head of the Mulmix R&D department.
'The revolutionary part of removing the columns allows us to add great flexibility to meet the various needs of our customers.'
Proven and potential advantages of this silo design:
- Cleaning: due to the presence of the cone, the silo remains perfectly clean.
- Organic: ideal for those who handle organic products.
- Hermetically sealed: these silos are also prepared for treatment with nitrogen or CO2.
- Maintenance: all the machines are protected against harsh weather conditions.
- Civil works: a simple platform with above-ground machines.
These new bins range from 3.70 to 12 metres in diameter and have a capacity of 100 to 2,000 tonnes.
This design also supports the FIFO method (First In, First Out). A counter cone on the inside of the silo aids ventilation and facilitates the release of the first product that enters, thus preventing the first silage product from staying inside for too long.
The prototype, made at the Mulmix factory, was inspected and stress-tested over a long period of time. Finally, after positive assessment by their structural engineering consultants, it was put into production.
The coupling bolts are 12 micron galvanised and salt spray-tested, which provide excellent resistance in all possible installation contexts. For more specific requirements and increased cleanliness, the coupling bolts are mounted in such a way as to prevent any build-up of the product.
Excellent customer feedback
'Our internal cone silos are highly versatile and we have received excellent feedback from our customers where we have already installed them, not only with regard to the type of silos but also to the quality-to-price ratio,' states Nicola Lorenzo Finco, CEO of Mulmix.
'Our production unit is working flat out to meet the demands we receive from all over the world. Going ahead with the patent for this unique coupling system was an excellent decision, since no rival company offers a similar system.
From the patent presentation by the Padua-based firm, which oversees our patents and prepared all the documents to be deposited to obtaining the patent, it took about eight-to-nine months,' concludes Mr Finco, who is satisfied with the results.
