The primary barrel at Hermitage Quarry has undergone a major refurbishment to ensure that it continues to work at its optimal level. This follows over 7 million tonnes of throughput since its commission in 2006.

The primary barrel is a critical part of the quarry’s processing plant. It is a long barrel in three sections, each section having differing mesh sizes. It is the first piece of the processing plant – after the dump trucks have deposited the raw material into the hopper, it passes through the primary barrel and smaller material drops through the mesh, separating the smaller material. The process of agitation separates the majority of the hassock (clay and sand) from the hard Kentish Ragstone, prior to the Kentish Ragstone going on to further processing. The primary barrel is therefore a very important piece of the process and the major refurbishment it underwent over the Christmas period has ensured that it is now good for continued use over the coming years.
