An excavator loads the loosened limestone into dump trucks for delivery to the on-site crushing plant. This continuous-feed process crushes limestone chip into a range of sizes. Limestone chip 15–50 mm in size is sent to the calcination plant, while other sizes are used in other processes. Acknowledgement: McDonald's Lime Limited. Step 3.
Both quicklime and hydrated lime are dry bulk products derived from limestone (calcium carbonate, CaCO 3). The calcium oxide material known as Quicklime (sometimes called lime) is produced by heating limestone in a kiln to drive off carbon dioxide (calcination). Adding water to quicklime initially produces dry hydrated lime.
