Clinker manufacture operational: 1892-1932
Approximate total clinker production: 240,000 tonnes
Raw materials: Chalk Marl (West Melbury Marly Chalk Formation: 97-100 Ma) from pit at 560800,268550. It seems likely that Grey Chalk (Zig-zag Chalk Formation: 94-97 Ma) - perhaps lime works rejects - was also brought by rail from Burwell village after 1904.
Ownership: R. Stephenson and Son
The company had a lime plant in Burwell village at 559160,266150. A new marl pit extending down to the "coprolite" layer was opened at 560800,268550 in around 1899 and a single bottle kiln was installed for making cement, burning as-dug marl. In around 1901, a Schneider kiln was built, and a further three were added around 1904: Davis gave its output at 250 t/week in 1907 . Its capacity apparently continued at this level until closure. Robert Stephenson, who had multiple interests in the area, died in 1929. Various sources suggest the plant closed in 1926 (the last directory reference) but it is clear that the plant was still operating at the time of Stephenson’s death. The plant was originally isolated, but acquired a spur of the Great Eastern railway by 1901. BPCM acquired the chalk land as part of the reserves of the Norman plant, but never exploited it. The Ordnance Survey map labels the quarry as a clay pit, but it certainly produced chalk marl. The plant site appears to be a scrap yard, with overgrown ruins. The marl pit is flooded.
No rotary kilns were installed.
