Typical Flow of Aggregate Production Line

Working Principle:

The motor drives the operation of the relevant equipment, and the ZSW vibrating feeder evenly sends the materials into the PE jaw crusher (first-level crushing). After crushing, the material enters the PF counterattack crusher (secondary crushing) for further refinement and shaping; the crushed materials are transported to the YK circular vibrating screen to complete the grading screening, remove impurities, and separate sand and stones of different particle sizes; the whole process realises the integrated operation from feeding, crushing to screening through automated connection, and finally produces clean sand and stone finished products that meet the requirements.

Application Areas:

1. Core application scenarios: large-scale sand and stone production in sand and stone factories, on-site crushing and processing at construction sites, supporting sand and stone processing in the construction of concrete dams in hydropower stations, sand and stone preparation at road construction sites, rock crushing and screening after mine mining, etc., which can realise automated continuous operation and adapt to different scales of production needs.
2. Main application fields: covering the field of building materials (used for the preparation of sand for concrete mixing, wall masonry and other construction), the field of roads and bridges (used for road foundation filling and sand and stone processing for road surface laying), the field of water conservancy and hydropower (used for supporting sand and stone treatment for dams and reservoir construction), mine mining field (used for medium hardness to Down rock crushing and screening), at the same time, it can be adapted to the sand and stone washing and grading needs of post and telecommunications pole factories, foundries, glass factories and other scenarios.

Product Maintenance:

1. Daily maintenance: clean up the surface of the equipment and the debris of the feed port and the discharge port every day, check the tightness of the connection parts of each equipment, and tighten the loose parts in time; regularly check the lubrication part and replenish the lubricating oil to ensure the smooth operation of the equipment; clean up the debris of the vibrating screen to prevent blockage.
2. Regular maintenance: check the operating status of the motor and reducer every week, and troubleshoot the insulation of the line; check the wear of the crusher hammer head, lining plate, vibrating screen and other wear parts every month, and replace it in time; conduct a comprehensive inspection of the equipment every quarter to repair potential faults.
3. Long-term downtime maintenance: thoroughly clean up the residual materials in the equipment, do a good job of dustproof and moisture-proof treatment; empty the grease of the lubricating system, replace the new grease before starting again, and comprehensively check the status of the equipment before starting.
4. Notes: Before maintenance and overhaul, the power supply of the equipment should be cut off, and it is strictly forbidden to operate with electricity; consumable parts need to be adapted to avoid affecting the operating efficiency and service life of the equipment.
