Recycling News
The plant had to be designed to cope with a fluctuating silt content, removal of organics and plastics and separation of both ferrous and non-ferrous metals. In particular, containment and removal of polystyrene out of the system and the ability to keep the wash water clean.
A successful installation:
After a successful installation and commissioning the new wash plant is currently processing a large variety of trommel fines and inert recyclable aggregates. The plant is producing clean fine sand, coarse sand, and 10mm, 20mm and 40mm aggregate along with ferrous and non-ferrous metals.
In addition, a full water treatment plant has been incorporated with a twin overhead beam filter press to recycle up to 95% of the water and produce a dry filter cake.
Tyrone T-Scrub 1100 wash plant:
Designed to wash and thoroughly clean the most difficult recycled aggregates this machine can process up to 60tph and produce three washed aggregates. The sand is pumped to the T-Sand 084 for further classification; it is then double washed through hydro cyclones to remove all the -5mm trash and silt fraction and split into fine sand and coarse sand. With a robust design and incomparable access, cost of ownership is reduced, and plant utilisation is maximised.
The +5mm trash is floated out of the back of the T-Scrub logwasher and the -5mm trash is removed on a vibrating screen prior to the water treatment plant. There is also a
surface scraper on the thickener to remove any fine trash material and fibres which ensures the water is kept clean.
The plant layout includes extensive walkways for operator maintenance and servicing and is fully automated for ease of operation. The overhead beam filter press offers unrivalled access for ease of maintenance and has very few moving parts reducing cost of ownership.
George Sharp – Director commented, “We are very happy with the quality of the materials produced and the performance of the Tyrone plant. This operation has helped us future proof our business, provide a solution for our trommel fines and open new markets for our business.
“The circular economy and sustainable growth are an important factor in all our decisions and our new wash plant will help us to achieve our goals.”
