Sometimes called Southerham Works. The site had produced grey and white lime since the late eighteenth century from two distinct quarries 0.5 km apart: Navigation Pit to the north (542500,109900) and Southerham White Pit to the south. Cement manufacture began at the more northerly site in 1906 with a block of seven chamber kilns (200 t/week). A further four kilns were installed in 1912 giving a total 320 t/week. The chamber kilns were abandoned following the installation of the rotary kiln, which was placed in the southerly quarry. The plant was the smallest in the UK from the 1960s onwards. There was a plan to triple the size of the plant in 1968 (although still wet process), but planning permission was denied in this scenic semi-urban location. Final closure in 1981 was ostensibly due to the installation of Rochester A6. The plant used a spur of the LB&SC railway for transport. The site remained a depot for a short time after closure then was cleared and is now an industrial estate. The white quarry is occupied by a recycler and the grey quarry is waste land.

Please contact me with any relevant information or corrections. I am particularly interested in firmer dates and statistics.

One rotary kiln was installed:

Kiln A1

Supplier: FLS
Operated: ?1/1928 -31/07/1981
Process: Wet
Location: hot end 542605,109517: cold end 542614,109592: hot end enclosed.
Dimensions (from cooler ports): Metric:

  • 1928-1935 50.00 × 2.400B / 2.100CD
  • 1936-1981 75.00 × 2.400B / 2.100C / 2.400D

There is some confusion about the Lewes kiln. It is clear from maps and photographs that the kiln was initially much shorter and was extended in the 1930s, but the FLS reference list says it was 75 m as installed.
Rotation (viewed from firing end): ?
Slope: 1/25 (2.292°)
Speed: ?
Drive: ?
Kiln profile:

Cooler: Unax planetary ?11 tubes
Fuel: Coal
Coal Mill: ?
Exhaust: via ID fan direct to stack. After the lengthening of the kiln, cyclones were added before the ID fan. An electrostatic precipitator was added in 1980.
Typical Output: 1928-1935 125 t/d: 1936-1966 180 t/d: 1966-1981 210 t/d
Typical Heat Consumption: 1928-1935 8.23 MJ/kg: 1936-1966 7.57 MJ/kg: 1966-1981 7.13 MJ/kg
