Subject: High Quality Jc5000 Jaw Crusher Quotation – Optimizing Primary Crushing for HighVolume Operations

1. PAINPOINT DRIVEN OPENING

Is your current primary crushing stage becoming a bottleneck in your aggregate or mining circuit? Many operations face the compounding costs of premature jaw plate wear, frequent toggle plate failures, and inconsistent product sizing. Industry data indicates that unscheduled downtime for jaw crusher maintenance can cost a midsized quarry between $8,000 and $15,000 per hour in lost production. Additionally, a crusher that cannot handle a consistent feed of 500600mm material often requires costly secondary blasting or hydraulic hammering, adding $2.50 to $4.00 per ton to operating costs.

Are you struggling to maintain a tight closedside setting (CSS) under high tonnage loads? Does your current machine require excessive lubrication and bearing maintenance, driving up your total cost of ownership? The High Quality Jc5000 Jaw Crusher is engineered to address these specific operational challenges, providing a robust solution for highvolume primary reduction.

2. PRODUCT OVERVIEW

The High Quality Jc5000 Jaw Crusher is a heavyduty, singletoggle primary crusher designed for continuous operation in hard rock mining and largescale aggregate processing. It operates on the principle of compressive crushing between a fixed jaw and a moving jaw (swing jaw), driven by a large eccentric shaft.

Operational Workflow:
1. Feed Intake: Runofmine (ROM) material (up to 800mm) is fed into the Vshaped crushing chamber via a feeder or directly from a dump truck.
2. Compression Cycle: The eccentric shaft rotates, driving the swing jaw in an elliptical motion against the fixed jaw. Material is crushed as it moves downward through the chamber.
3. Product Discharge: Crushed material exits through the adjustable closedside setting (CSS) at the bottom of the chamber.
4. Hydraulic Adjustment: The CSS is adjusted via a hydraulic wedge system, allowing for quick setting changes without manual shimming.

Application Scope:

• Primary Crushing: Basalt, granite, river gravel, iron ore, and limestone.
• Feed Size: Up to 800mm (31.5 inches).
• Product Size: Typically 100mm to 250mm depending on CSS setting.
• Limitations: Not suitable for sticky clay materials (moisture >8%) without a grizzly feeder; requires a heavyduty foundation to absorb dynamic loads.

6. APPLICATION SCENARIOS

Hard Rock Quarry (Granite) | Challenge: A quarry in Norway processing 400 TPH of granite (UCS 250 MPa) experienced 8 unscheduled shutdowns per year due to cracked frame welds on their previous crusher. | Solution: Installed the Jc5000 with a cast steel frame and hydraulic CSS adjustment. | Results: Zero frame failures in 24 months of operation. Throughput increased from 320 TPH to 410 TPH. Wear part life extended by 45%, reducing annual consumable costs by $12,000.

Iron Ore Mine (Primary Crushing) | Challenge: A mine in Western Australia needed to reduce ROM ore from 700mm to 150mm at a rate of 350 TPH, but their existing crusher could not handle the high silica content, causing rapid jaw plate wear. | Solution: Deployed the Jc5000 with reversible Mn13Cr2 jaw plates and a deep chamber profile. | Results: Jaw plate life increased from 3,200 hours to 5,800 hours. The reversible feature allowed one extra wear cycle before replacement. Total costperton for crushing dropped from $0.18 to $0.12.



River Gravel Processing Plant | Challenge: A plant in Germany processing 250 TPH of river gravel needed to reduce feed size from 500mm to 80mm for a cone crusher feed. The existing jaw crusher produced excessive fines. | Solution: Utilized the Jc5000 with a tight CSS of 80mm and optimized nip angle. | Results: Product gradation improved, with fines (5mm) reduced by 18%. The cone crusher downstream operated at 95% capacity, up from 80%. Energy consumption dropped by 0.12 kWh/ton.

8. FAQ

Q1: Can the Jc5000 handle wet or sticky material?
A: The Jc5000 is designed for dry to moderately moist material (moisture up to 6%). For sticky clay or highmoisture feed (>8%), we recommend installing a vibrating grizzly feeder with 50mm spacing ahead of the crusher to scalp fines.

Q2: What is the typical lead time for a Jc5000 order?
A: Standard configuration orders typically ship within 810 weeks from order confirmation. Enhanced and full package orders require 1214 weeks due to hydraulic component sourcing.

Q3: How does the hydraulic CSS system perform in cold climates?
A: The system uses ISO VG 46 hydraulic oil with a coldweather additive. It is rated for operation down to 20°C. For sustained operation below 15°C, an optional oil heater is recommended.

Q4: What is the expected lifespan of the main bearings?
A: Under normal operating conditions (CSS 100150mm, 300 TPH), the spherical roller bearings typically last 14,00018,000 hours. Regular greasing and proper belt tension are critical to achieving this lifespan.

Q5: Can the Jc5000 be integrated into an existing plant with a different motor voltage?
A: Yes. The crusher is supplied without a motor by default. We can provide a motor pulley to match your existing motor (380V, 415V, 660V, or 3300V). Please specify your motor shaft diameter and RPM when ordering.

Q6: What is the warranty coverage?
A: Standard warranty covers 12 months from commissioning or 18 months from shipment, whichever comes first. The enhanced package includes a 24month warranty on the frame and eccentric shaft against manufacturing defects.

Q7: How often should the toggle plate be inspected?
A: We recommend visual inspection every 40 operating hours. The toggle plate is designed as a sacrificial component to protect the frame from uncrushable material. Replace immediately if any cracks are visible.
