Jul 18, 2017 The history of Cape Lime dates back to 1946 when the first vertical shaft kiln was commissioned by Cape Lime Company Ltd on the farm Langevallei near Robertson in the Western Cape. Today, Langvlei has three kilns in operation calcining dolomite, which is mined and crushed on site. It also boasts the only pressure hydrator in South Africa.
OriginsOur roots date back to the nineteenth century when in 1889 Hippolyte Dumont opened a factory in Belgium. In just over a century, the firm has spread internationally first to France in 1926 on the impetus of the founders son-in-law, L on Lhoist. He developed the company further by acquiring lime, limestone and dolimite plants in Belgium and France.
When UK lime manufacturer Steetley Dolomite started burning a combination of waste solvents and low calorific value coal in its three rotary kilns, product quality did not suffer, but throughput fell. By using Air Products proprietary oxygen injection technology, Steetley Dolomites production increased about 10,
The site was the location of a large limestone operation in the late 19th Century. The Milwaukee Falls Lime Company was incorporated in 1890 and produced lime here until about 1920. At one time, there were five lime kilns here, at a time when Wisconsin was third in national lime production.
