Selecting the Right Aggregate Washing Classifying Equipment

Selecting the Right Aggregate Washing Classifying Equipment

 · Aggregate producers need to wash concrete and asphalt sands for several reasons. They need to remove lightweight particles such as lignite, mica and shale. They need to remove other undesirable particles such as sand in a gravel pile. Producers often have to alter feed gradation to meet a design spec. And many times, producers need to blend multiple feeds when material is being supplied .

Classifiion of Aggregates

Lightweight aggregates: As mentioned in the body of this paper, lightweight concrete contains aggregate that is natural or synthetic which weighs less than 1100 kg/m 3. The lightweight is due to the cellular or high internal porous microstructure, which gives this type of aggregate a low bulk specific gravity. The most important aspect of lightweight aggregate is the porosity. They have high ...

Lightweight aggregate is relatively new material. For the same crushing strength, the density of concrete made with such an aggregate can be as much as 35% lower than the normal weight concrete. In addition to the reduced dead weight, the lower modulus of elasticity and adequate ductility of lightweight concrete may be advantageous in the seismic design of structures. Other also .
