Project background
Jinan YitongIt is a wholly-owned subsidiary of Jinan Lixia Holding Group，It is a municipal state-owned key large-scale construction enterprise.。To meet the bridge、Requirements for the construction of roads and some civil engineering projects，Guarantee the quality of sand and gravel aggregate of the project，After a number of comparisons and on-site inspection of Nanfang Road Machinery Equipment,，Jinan Yitong chooses to join hands with Nanfang Road Machine，Build 300 tons per hourFCP300+ZS3-1030 sand and stone production line。Hard rock crushing process is adopted for the front section of the production line.，Set broken、Screening、Plastic surgery、Sand making、Dust removal is integrated ，The rear end is equipped with modular stabilized soil plant mixing equipment of Nanfang Road Machine.、Asphalt concrete recycle material screening equipment，Complete set of equipment automatic assembly line operation，Green and low carbon、Smart and efficient。
Production process flow
Particle size 700mmThe following raw materials enter the crushing production line of Nanfang Road Machine by forklift。The forklift pours the raw materials into the feeding bin of the jaw crusher，A grate feeder is arranged below the feeding bin to convey the large-size aggregate to the jaw crusher for coarse crushing.，The small particle size of the grate pre-screen is conveyed to the residue screen for soil removal.。The clean aggregate from which the muck has been removed joins the aggregate from which the jaw has been broken，Conveyed to the conical crushing buffer bin by the belt conveyor，Meanwhile, the belt conveyor is provided with a self-unloading iron remover.，Can play a very good role in protecting the cone.。
And then，The buffer bin of the cone crusher is evenly fed to the cone crusher by the vibrating feeder at the bin bottom.。Aggregate enters the cone crusher for crushing，Further reduce the aggregate size；Dividing the aggregate into 0 and 0 by a circular vibrating screen,-5mm、5-40mmAnd great than 40mmThree aggregates。0-5mmThe aggregate is conveyed to the rear material warehouse by the belt conveyor.；5-40mmThe aggregate is sent to the sand making buffer bin.，Of which 20-31.5mmAggregates can also be selected to enter the back-end silo.；Greater than 40mmThe aggregate is used as the return material and continues to enter the cone crusher to be crushed again.。
Sand making buffer bin 40mmThe following aggregates，Feeding through the frequency conversion belt conveyor at the bottom of the silo，The raw material is sent to the main shaping machine by the belt conveyor for crushing.。The aggregate crushed by the shaper enters the vibrating screen for screening from the chute.，Sieve the aggregate to 0-3mm、3-10mm、10-15mm、15-26mmAnd＞26mmGrade 5 finished aggregate；Among，＞26mmThe aggregate is returned to the shaping host for secondary crushing.。0-3mmWet the aggregate in the humidifier，3-10mm、10-15mm、15-26mmThe aggregate is blown，And that pow content of the aggregate is reduced，Delivered to finished product warehouse via belt conveyor。
Each aggregate transfer point on the production line、Dust points shall be sealed with negative pressure for dust prevention.，Prevent dust from flying。In addition，The aggregates sent to the finished product bin shall be uniformly humidified.，Ffectively avoid material falling and dust raise。
