Aggregate, in building and construction, material used for mixing with cement, bitumen, lime, gypsum, or other adhesive to form concrete or mortar. The aggregate gives volume, stability, resistance to wear or erosion, and other desired physical properties to the finished product. Commonly used aggregates include sand, crushed or broken stone, gravel (pebbles), broken blast-furnace slag, boiler ashes (clinkers), burned shale, and burned clay. Fine aggregate usually consists of sand, crushed stone, or crushed slag screenings; coarse aggregate consists of gravel (pebbles), fragments of broken stone, slag, and other coarse substances. Fine aggregate is used in making thin concrete slabs or other structural members and where a smooth surface is desired; coarse aggregate is used for more massive members.
Some offers jaw crusher, impact crusher, stone crusher, cone crusher, vertical shaft impact crusher and drying hammer mill.
These crushers are designed to handle a wide range of crushing applications from primary, secondary, and tertiary hard rock crushing to mixed demolition debris, crushed or broken concrete and asphalt, sand & gravel and quarried stone. Stationary and portable systems are also available.
Jaw Crusher is one of the most common crushing equipment. It is mainly applied in crushing the material with the compressive strength under 320Mpa. This jaw crusher is usually used in the field of mining, metallurgy, road & railway construction, water conservancy, chemical industry and so on. The jaw crusher of medium and large size designed and manufactured by our company have reached the advanced level with the features of high crushing ratio, high capacity, uniformed product size, simple structure, reliable operation, easy maintenance and low operation cost. PE series is usually used in coarse crushing, and PEX is used in secondary and fine crushing.
