Wholesale Crushing And Screening Equipment Assembly Plant

Your Crushing and Screening Bottlenecks Are Costing You $12,000+ Per Day in Lost Production

Every hour of unplanned downtime at your aggregate or mining operation erodes profit margins by an average of $500–$1,500, depending on throughput. Plant managers report that 60% of these stoppages stem from poorly integrated crushing and screening equipment assembly—misaligned conveyors, undersized screen decks, and incompatible crusher settings.

You face three recurring challenges:

• Inconsistent product quality that triggers rework cycles, wasting 8–12% of total material processed
• Frequent screen blinding and crusher bridging that forces manual intervention, creating safety hazards and 45minute cleanup delays
• Assembly complexity that extends commissioning timelines by 3–5 weeks, delaying revenue generation

Can your current crushing and screening equipment assembly plant deliver consistent output within spec, without requiring constant operator oversight?

Product Overview: Integrated Crushing and Screening Equipment Assembly Plant

This wholesale crushing and screening equipment assembly plant is a preengineered, modular system designed for continuousduty mineral processing. It integrates primary jaw crushing, secondary cone crushing, and multideck vibrating screening into a single, transportable assembly.

Operational Workflow:

1. Feed Hopper & Apron Feeder – Receives runofmine material up to 800 mm, regulates feed rate via variablespeed drive
2. Primary Jaw Crusher – Reduces material to 150–200 mm at 250–400 tph capacity
3. Overband Magnetic Separator – Removes tramp iron before secondary crushing
4. Secondary Cone Crusher – Produces 20–40 mm aggregate with closedside setting adjustment
5. TripleDeck Vibrating Screen – Classifies material into 0–5 mm, 5–20 mm, and 20–40 mm fractions, with recirculation conveyor for oversize

Application Scope: Hard rock quarries, river gravel processing, construction and demolition waste recycling, iron ore beneficiation plants.

Limitations: Not suitable for wet, sticky materials exceeding 15% moisture content without additional drying equipment. Maximum feed size limited to 800 mm.

FAQ

Q: Can this crushing and screening equipment assembly plant handle recycled asphalt (RAP)?
A: Yes, with the optional impact crusher and heated screen decks. RAP requires lower crushing forces to avoid binder degradation. The system's variablespeed feeder and adjustable crusher settings accommodate RAP feed rates up to 350 tph. We recommend the heated deck option to prevent screen blinding from tacky asphalt.

Q: What is the expected lifespan of major components?
A: Field data from 47 installations shows: jaw crusher liners: 8–14 months (depending on abrasivity), cone crusher liners: 6–10 months, screen media: 12–18 months, mainframe structure: 15+ years with proper maintenance. Bearing replacement intervals average 18,000 operating hours.

Q: How does the assembly plant perform in cold climates?
A: The system operates down to 20°C. Standard features include coldweather hydraulic oil (ISO VG 32), heated bearing housings, and insulated control panel. For sustained operation below 15°C, we recommend the Arctic package ($22,000) which adds frame heaters and heated lubrication lines.

Q: What electrical infrastructure is required onsite?
A: Minimum 450 kVA transformer for CSS500, 650 kVA for CSS750. The plant includes a main disconnect switch and motor control center. Your site needs 380–480 V, 3phase, 50/60 Hz supply. We provide cable lengths up to 50 meters from the MCC to the plant.

Q: Can the plant be expanded later?
A: Yes. The modular design allows adding a tertiary crusher, additional screen deck, or washing system. The mainframe includes predrilled mounting points for future expansion. Maximum capacity after expansion: 900 tph (CSS750 base).

Q: What training do operators need?
A: The Advanced and Premium tiers include 3day onsite training covering: startup/shutdown procedures, crusher setting adjustments, screen media inspection, and PLC fault diagnostics. Operators with 2+ years of crushing experience typically achieve proficiency within 5 shifts.

Q: What warranty covers the equipment?
A: Standard warranty: 12 months from commissioning or 18 months from shipment, whichever comes first. Coverage includes manufacturing defects in materials and workmanship. Excluded: wear parts (liners, screen media, belts), damage from improper operation, and modifications without authorization. Extended warranty available as noted above.
