  • Grid reference: SE95010109
  • x=495015
  • y=401095
  • 53°29'53"N; 0°34'3"W

Clinker manufacture operational: 1920 - 1976

Approximate total clinker production: 9.3 million tonnes.

Raw materials: quarry at 494500,401800 supplying materials all of Inferior Oolite age - Lincolnshire Limestone Formation - (top to bottom):

  • relatively pure cream-coloured Lincolnshire Limestone (Hibaldstow Limestone: 168-170 Ma)
  • grey shale (Kirton Cementstone Mudstone: ~170 Ma: mostly side-cast)
  • argillaceous limestone (Kirton Cementstone Limestone: 170-171 Ma)

Ownership:

Also known as Central Works. The “Blue Lias Lime and Cement Works” (which made neither Blue Lias lime nor cement!) had been opened on the site in 1882 by H Parry and Sons, and a bank of lime kilns still remains to the north of the plant site. Later called the Kirton Tunnel lime works, it was established where the Gainsborough-Brigg line of the Great Central Railway cuts through the Oolite ridge, and used the railway for transport.

The setting up of a cement plant seems to have been planned before WWI, and G & T Earles, who were installing FLS kilns at Wilmington, seem to have provided surreptitious consultancy. Although the raw materials were ideal for dry process, this technology was not available from British suppliers or FLS.

With the plant in decline, the installation of kiln 5 (a kiln of obsolete design) in 1968 remains a mystery to me. The plant closed with the first post-oil-crisis contraction. The site now functions as a recycling depot. Many buildings are intact, and some of the kiln section foundations are still visible.

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

Rawmills

? unknown but presumably ball mills

Five rotary kilns were installed:

Kiln A1

Supplier: FLS
Operated: 10/1920 -13/01/1967
Process: Wet
Location: hot end 495006,401123: cold end 495051,401127
Dimensions: Metric 45.00 × 2.400B / 2.100CD
Rotation (viewed from firing end): ?
Slope: 1/25 (2.292°)

Cooler: rotary 51’0” × 4’7” (metric 15.54× 1.397) beneath kiln. This was the final form, but it is not an FLS design and it looks as though it must have been a replacement for an original concentric rotary design, since kilns 1 and 2 were "sisters" to Wouldham kilns B7 and B8.

Old Maps

A detail plan of the plant has been partially completed, but further progress is prevented by lack of information on the layout of kiln 5.
