Some time ago, there was a client investment plan for an annual output of 5 million tons of green building materials, using ground fixed coarse crushing technology, and a total of four kinds of building stone products, including particle size of 31.5-20mm, 20-10mm, 10-4.75mm, -0.075mm of building rubble and mechanical sand less than 4.75. In order to achieve the comprehensive utilization of resources, stone powder with a particle size of less than 0.15mm is also used as an accessory product for use in commercial concrete and unburned brick products.
Kefid has accumulated a wealth of practical experience, the case site throughout the mining, cement, metallurgy, chemical, construction waste and other fields, can provide EPC project total package and other solutions. With an annual output of 5 million tons of green building materials, 300-350 tons of sand production line equipment can be used. The stone is blasted from the hill and the stone less than 750mm is fed into the vibrating feeder through a dump truck. Then the stones are evenly fed into the jaw crusher. The jaw crusher crushes stones for first stage. The impact crusher crush the stones for second stage. The material that is larger than 40 mm is returned by the round vibrating screen for re-crushing, stones below 40mm are sent to the sand making machine and finally classified.
