At Kelly’s of Fantane, we produce a variety of quarry products. The various grades and sizes are the product of our quarrying processes.
The quarrying process begins with the explosives company carrying out an in-depth survey of the quarry face. Shot holes are drilled into the area to be blasted. Explosives are placed into these holes. After denotation of the explosives, stockpiles of large rock are deposited onto the quarry floor. This rock is transported to the primary crusher. Our primary crusher is a jaw crusher. This crusher is used in the first stage of crushing to reduce the blasted rock to a size that can be processed by the secondary crusher. The crushed rock from the primary crusher is conveyed onto the primary stockpile. The secondary crusher is fed from this stockpile. The rock from the secondary crusher is conveyed onto a multi-deck screen. This multi-deck system screens out small crushed rock and dust into a separate stockpile. The larger size rock is conveyed to the tertiary crushing operations where they are fed through a series of cone crushers and multi-deck screens.
The result of all this crushing and screening are several different aggregate products that comply with our customer requirements and the requirements of the National Roads Authority Specification For Road Works.
