New Gear & Pinion for 50-year-old Ball Mill
Tucked away in the corner of a modest processing facility in Cumbria UK, there’s a British Rema ball mill that has been in continuous operation processing Activated Carbon since 1973. After over 50 years of use, however, it was definitely time for some much-needed refurbishment.
The customer contacted British Rema in 2023 due to some excessive noise and vibration coming from the girth gear and pinion arrangement and upon inspection, it was clear the two components were at the end of their service life and would require replacement.
This posed somewhat of a challenge due to the age of the ball mill, but the British Rema design team delved deep into the archives and found the original drawings and parts lists on Microfilm which were all in imperial dimensions!
The team set to work re-drawing the girth gear, pinion and pinion shaft in metric dimensions to the exact specifications of the original ball mill and once all drawings and checks were complete, the replacement components were produced and prepared for fitment.
The British Rema Rotary Engineering team successfully removed the original parts and installed the new ones ready for the ball mill to get back to work.
The whole project was executed on time, to budget and most importantly, with zero damage to any equipment or people and no unanticipated downtime. The client was highly satisfied with the exceptional result and is delighted that the rejuvenated ball mill now has the capability to operate for many more years to come and production targets can be confidently met without fear of mechanical failure.  Â
No matter the age, size, location or OEM of your rotary kiln or ball mill, British Rema has the engineering capabilities and expertise to think ‘outside the box’ and support customers from the design stage of a project, through the manufacturing phase and into final installation and commissioning.
