    lower front end The product is then discharged from the kiln into a cooler where it is used to pre heat the combustion air Kilns of this type are usually fed with stone ranging in size from 15mm to 40mm and are fuelled by a range of fuels including coal petroleum coke natural gas and waste derived fuels They are used to produce Dolomitic lime and higher purity quicklime used for the manufacture of low carbon steel fibreglass and healthcare products In particular rotary kilns are also used to burn Dolomitic limestone at high temperatures to produce sintered Dolomite Twin Shaft Parallel Flow Regenerative Kilns Twin shaft parallel flow regenerative kilns have two inter connected vertical shafts which are fired in sequence to achieve excellent energy efficiency The stone size used by these kilns is usually between 90mm and 125mm They are on the whole fuelled by natural gas and produce high reactivity and high purity quicklime This is often used in industrial effluent treatment domestic sewage treatment manufacture of aerated concrete blocks steelmaking and soil stabilisation Hydrating Lime Quicklime can be processed even further into hydrated lime by adding water Depending on the facilities at the quarry this can occur either on site or by transporting the lime to a separate hydrating plant A basic hydrating plant consists of four stages Quicklime handling and crushing Hydration Classification Storage and despatch Handling and Crushing Where the removal of impurities in the hydrating plant is not important the quicklime is often reduced in size using impact breakers In other circumstances rolls and jaw crushers or cone mills may be used Hydration Hydrators usually consist of three main sections prehydrator hydrator and finishing stage The plant consists of numerous paddles that help to mix water and quicklime quickly and efficiently from start to finish The plant is kept under slight suction to prevent any dust emissions throughout the process The final moisture content of the raw hydrate after the finishing stage is usually about 1 Classification The raw hydrate is then taken from the hydrator to the classification plant Depending on the customers specification the raw hydrate can be adjusted even further to meet their requirements Storage and Dispatch All finished products whether they be Dolomitic lime quicklime or hydrated lime can be stored on site prior to transportation by rail road or ships Alternatively they can be packed into bags which are then purchased by a range of customers including steelmakers DIY stores and builders merchants Dolomitic Lime Introduction Dolomitic lime is made from Dolomitic limestone CaCO 3 MgCO 3 heat CaO MgO 2CO 2 It is a mixture of lime CaO and magnesia magnesium oxide MgO Dolomitic limestone is formed by the replacement of some of the calcium in limestone with magnesia a process known as Dolomitisation Dolomitic lime is also known as Calcined Dolomite Dolime Lightly calcined Dolomite Burnt Dolomite Production Dolomitic lime is produced using rotary kilns fired with natural gas coal petroleum coke and a range of
