Aggregate crushing plant for producing sand and stone in highway construction Author:GreatWall Posted:2014-07-21 Views:
There are strict high requirements on sand and stone granularity and gradation in highway aggregate crushing plant, especially the needle grain proportion of  basalt and diabase gravel.In order to solve the particle size and size distribution, particle shape and  particle composition, Great Wall heavy industry machinery company adopts the new types aggregate crusher,  which can better meet the demands of highway cement and asphalt on sand and gravel aggregate crushing plant.Great Wall heavy machinery engineers analysis the whole  stone production line in highway construction.
We will illustrate the flow chart in the Highway aggregate crushing process,mining stone is done primary crushing by jaw crusher via vibrating feeder.Generally speaking,we adopt cone crusher  as medium crushing equipment,the product will be screened by vibrating screen after being crushed in cone crusher.If there are output size granularity bigger than 40mm,they will be conveyed into cone crusher for crushing again.The qualified grain are fine crushed by VSI sand making machine.and then we can get the wanted finished products,their size is below 20mm, and then they are transported to products piles.Great Wall new type aggregate crushing plant has the features of high automation degree,low investment and high profits,The output size is even granularity and good shape,therefore aggregate crusher plant is needed in highway construction.
