Screw Press using 14% of the Power of an equivalent Centrifuge
Huber Technology have taken their well proven Screw Press (RoS3Q 440) and have designed and built a larger Screw Press (RoS3Q 800) to meet the market requirements for larger works.
The new 800 diameter unit competes directly against a 350-400mm diameter centrifuge. Having briefly entered the centrifuge market Huber concluded that Centrifuges did not meet their environmental ethos of a low Carbon footprint process whilst the Screw press complied.
Comparing the RoS3Q 800 Press alongside a Centrifuge Plant for a throughput of 450kg (DS)/ h the following results were achieved.
Taking a 3kw drive compared with the 22kw drive for the Centrifuge operated at 5000hours per annum at 15p/unit gives a power cost saving of £14,000 per annum and operating at 0.3 to 1.5 RPM compared with typically 3400RPM the maintenance savings in bearing life etc. are obvious.
Other advantages include elevated discharge making support structure unnecessary, low noise, less vibration, lower weight, and totally enclosed low pressure all stainless enclosure.
Recent tests on the smaller Screw Press compared with Centrifuges have shown savings in annual running costs of £50k and this new larger unit will give reliable service at considerably less whole life costs for 100,000 PE plants.
