Profile: Cheney Lime & Cement Company is specialized in producing high calcium quicklime and hydrated lime products. We quarry a large deposit of high calcium limestone, and use the processes of calcination and hydration to chemically convert the limestone into lime. The calcination process takes place in our rotary kilns and converts the limestone into quicklime, which is then available for bulk shipment. The hydration process involves taking a portion of the quicklime that has already been produced, and reacting it with enough water to produce a dry hydrated lime, which then becomes available for bulk or bag shipments.
