Aggregate Crusher And Grinding Mill

Aggregates are the raw materials for construction buiding, and they are inert granular materials such as sand, small-size gravel, or crushed stones.They along portland cement and water, are an essential ingredient in concrete making.Aggregate can be divided into two distinct categories-coarse and fine.Coarse aggregates are particles greater than 0.19 inch (4.75 mm), but generally range between 3/8 and 1.5 inche (9.5 mm to 37.5 mm) in diameter.Gravels constitute the majority of coarse aggregate used in concrete.Fine aggregates generally are consist of natural sand or crushed stones with most particles passing through a 3/8-inch (9.5-mm) sieve of vibrating screen.Sbm engineers are able to design and manufacture complete stone crushing plant and to provide optimum and most economical solutions according to customers requirements on stone specifications, output, application, etc.Large stone materials from the storage hopper are evenly and continuously fed into jaw crusher through vibrating feeder for primary crushing; the crushed materials are transported to cone crusher or impact crusher for fine crushing through belt conveyor; then the materials are transported to vibrating screen to be separated into different sizes.The end products with desired sizes will be transported to the final product pile and those with big sizes will return to the cone crusher or impact crusher for re-crushing.For further aggregate grinding, we recommend to you to choose mtw european trapezium grinding mill.It's improved on mtm trapezium grinding mill.Both the grinding mills are advanced than traditional ball mill.You can choose these grinding mills as aggregate grinding equipment.Alkaline activity test should be taken on the aggregate used in concrete in the conditions of water, soil, open or damp.Construction site should adopt local aggregate; metallurgical construction should pay attention to use the metallurgical slag, to shorten the distance and reduce shipping costs, develop resources and waste treatment harm profits.
