Processing Storage and Transport of Quicklime

A well-designed lime processing plant achieves a number of objectives, namely  

The processing plant should include adequate storage, both for the products and intermediates, to provide a buffer between the kiln, which is best operated on a continuous basis, and despatches, which tend to be at low levels overnight and at weekends. 

In traditional lime processing plants serving shaft kilns, the screened ROK lime then passed along a picking conveyor belt, where partially calcined lumps (sometimes called bullheads ) are removed, together with selected grades of lime. However, economic and social pressures have resulted in the phasing out of this activity in many countries. 

If the ROK lime has a top size in excess of (say) 45 mm, it is reduced in size with the minimum production of fines. Jaw and roll crushers are widely used for this duty. 

The crushed ROK lime is then fed to a multi-deck screen, which produces a secondary fines fraction (e.g. less than 5 mm), granular, and pebble , lime fractions (e.g. 5 to 15 mm and 15 to 45 mm). Oversize lumps (e.g., greater than
