Aggregate crushing process

Sand and aggregate crushing station is a good crushing equipment broken stone . With the increase of urban construction waste in recent years , broken equipment on the market a wide range of crushing equipment , Yifan Machinery Chinese professional aggregate crushing equipment manufacturers , the current service in Canada, the United States , Malaysia , Libya, South Africa, India , Italy and other world regions .The aggregate crushing process is divided into four different workshops : the crushing workshop , ultra- crushing workshop , in broken workshop , coarse broken workshop .

Crushing workshop: Asked crushing cars selected 4 PL9500SD , design and equipment line speed is 65m / s single piece of equipment power is 440kW , the design conditions of a single device handling capacity of 250t / h , workshop processing capacity of 1000t / h , equipment loading rate 83.3% . Crushing workshop design conditions of the feed particle size range of 3 ~ 40mm , material into the sand was 55% , sand fineness modulus FM 3.20 , the dust content of l8.5 % . The particle size of the crushing workshop ≤ 3mm sand into the finished sand material mixed with the ultra- crushing workshop warehouse .

Ultra- crushing plant:Ultra- crushing workshop selected the PL8500 type vertical shaft sand making machine , the design of the rotor linear velocity of 81m / s , workshop processing capacity of 140t / h , plant design feed particle size of 3 ~ 5mm , the material fineness modulus FM 3 .17 , the dust content of 15.2% .

Broken in the workshop :The crushed plant selected for the NP1110 and NP1213 type in broken crusher 2 , the design of the discharge opening size is 40mm , the design workshop treatment capacity of 920t / h , the maximum aggregate size design conditions car asked for 50mm, the design of crushing ratio of i2 = 5.0 .

Primary crushing plant: Selected the the NP1313 type crusher and three B13_56 - 2V type bar strip feeding machine for the primary crushing plant , the design of the crusher discharge opening opening is 150mm , bars feeder rods spacing b = 150mm, workshop design conditions the processing capacity of 1500t / h ; material yard blasting controlling the particle size D ≤ 800mm , designed to condition the coarse broken out broken than i expected maximum diameter of 250mm . = 3.2 .
