this aggregate is not suitable for most construction applications because of rounded rocks and varying ratios of sand to gravel; so it must be hauled to a crushing and screening plant. To haul raw material, or pit run as it is called in the industry, tonne rock trucks are loaded with excavators and sent to the the crushing spread.that means you want to have the right crushers up front to make the cubical shape in the feed before sending it to the screen plant. have the right type of crusher based on the raw material, and the finished product sizes that are required. make sure you choose the right type of crushing to minimize elongated material and maximize cubical material.
sep 10, 2015 also, screening is impractical for aggregate smaller than no. mesh, in which case, hydraulic separation, or classifying, becomes an important operation. washing and classifying of aggregate can be considered in two parts, depending on the size range of material. coarse material: generally above in.crushing process is the basis of getting the good sand and gravel aggregate. As the sand and gravel aggregate is growing, more and more customers are willing to invest in a crushing plant in the philippines. because crushing plant ph belongs to the heavy equipment, maybe it will cost you a certain amount of money.
aggregate is a widely used building material in modern engineering.
