By definition crushed stone is a construction aggregate It is created by mining a suitable rock formation and then using a crusher to break down the stone into different siz Crushed stone differs from gravel in that gravel has a more rounded shape and is made by the natural processes of In its simplest form concrete is a mixture of paste and aggregates rocks The paste composed essentially of portland cement and water coats the surface of the fine small and coarse larger aggregat Through a series of chemical reactions called hydration the paste hardens and gains strength to form the rock like mass known as concrete

I need to further comment on the influence of surge storage upon plant operation The provision of adequate surge storage at the right places in the flow line is of sufficient importance to warrant a little further consideration It is desirable in the crushing plant as it is in any production process to achieve a smooth and uninterrupted flow through the plant so that the reduction limited Aggregate producers handle water as part of their day to day operations but the majority of water handled during aggregate operations is re circulated Excess water is returned to the watershed Very little water is actually consumed or lost Quarries commonly extend below the groundwater table in order to extract rock

Presently about 90 of the aggregate production in Europe comes from naturally occurring resources quarries and pits Due to the increased demand for sand and gravel for construction purposes not only in building but also in road construction the last decade has seen a significant trend towards the use of more crushed rock aggregat This resource has been more and more preferred to sand for use as aggregates and used for the first time Most construction aggregates are produced from hard strong rock formations by crushing to produce crushed rock aggregates or from naturally occurring particulate deposits such as sand and gravel The most important sources of crushed rock in Britain are limestone including
