Sand Solutions

摘要

The correct source rock and correct crushing and screening process are the key factors in successful production of manufactured sand.The choice of crushers and screens depends on the feed material and required end-product use, eg ready-mixed concrete, mortar sand, asphalt sand etc. Metso Minerals believe that manufactured sand will play an increasing role in the future, because the predictability of the end product, in terms of particle shape, gradation and moisture content, will lead to potentially big savings and earnings for both the aggregate producer and the concrete manufacturer. For the aggregate producer, less waste material will be produced and a high-value sand will increase sales potential. For the concrete manufacturer, savings in cement will be a big motivator. High levels of predictability will also lead to lower costs due to reduced rejection rates. It is clear that the most suitable replacement for natural sand - a product created by the great forces of nature, albeit in a random process - is a product created by an industrialized and repeatable process.
