Ajax Equipment, Bolton, UK, has supplied the Lostock plant of Tata Chemicals Europe with a twin screw feeder, replacing an existing Ajax twin screw feeder which had been operating effectively for over 15 years. The feeder is used in the production of soda ash and provides a link in production between the centrifuge and fluidised bed dryer. Using a twin screw arrangement with a special outlet ensures an evenly distributed feed into the fluid bed. The machine is fabricated from carbon steel whilst the augers’ ribbon flights are made from wear-resistant steel. The feeder also includes an insulated jacket to maintain the desired temperature and prevent condensation.

 

Ajax technical director, Eddie McGee commented “Producing soda ash is a tough application, in this case with a high production output as well. Because of this, all parts of the production line must be of robust design and construction. Combining application-based design and careful material selection, Ajax’s screw feeder has performed reliably for the past two decades and we are confident the new machine will provide the same level of consistency” www.ajax.co.uk
