1. PAINPOINT DRIVEN OPENING

Your sand and gravel mining operation faces a constant battle: material handling costs consuming 3050% of your total operational budget. Every ton of aggregate moved from the pit face to the stockpile or loadout represents a direct hit to your margin. Are your haul trucks spending more time queuing than hauling? Is your loading equipment underutilized due to bottlenecks at the crusher feed? Do you lose 24% of your product to spillage and rehandling per shift? These inefficiencies in sand gravel mining factories logistics directly translate to lost revenue and missed delivery deadlines. The question is not if you need to optimize your logistics chain, but how to do it without a complete fleet replacement.

2. PRODUCT OVERVIEW

The HighCapacity Mobile Transfer Conveyor (MTC) System is designed specifically to bridge the gap between extraction and primary processing in sand gravel mining factories logistics. This equipment replaces the traditional haul truck cycle with a continuous flow of material.

Operational Workflow:
1. Feed Reception: A mobile hopper receives material directly from a wheel loader or excavator.
2. Primary Transfer: Material is fed onto a heavyduty, variablespeed apron feeder to control flow rate.
3. Overland Conveyance: A series of modular, tracked or wheeled conveyors transport material across uneven terrain.
4. Elevation & Discharge: A radial stacker or transfer tower elevates the material to the crusher feed bin or surge pile.
5. System Relocation: The entire system is moved via remote control or prime mover to follow the mining face.

Application Scope: Ideal for greenfield sites and existing operations looking to reduce truck haulage costs. Limitations: Requires a minimum feed consistency (no oversized boulders >24") and a planned path for conveyor relocation.

6. APPLICATION SCENARIOS

LargeScale River Gravel Operation | Challenge: A 2,000 TPH plant in the Pacific Northwest was losing 4 hours per shift to truck queuing and haul road maintenance. | Solution: Implemented a 1,200 TPH MTC system with three 150foot conveyor sections to feed the primary jaw crusher directly from the pit. | Results: Eliminated 6 haul trucks; reduced cost per ton from $0.42 to $0.18; increased plant runtime by 18%.

Hard Rock Quarry Conversion to Sand/Gravel | Challenge: A quarry in Texas needed to process a new sand deposit 800 feet from the existing wash plant. | Solution: Deployed a single 800foot MTC line with a mobile feed hopper. | Results: Avoided $1.2M in fixed conveyor civil works; system was relocated 3 times in the first year to follow the deposit; achieved payback in 11 months.

Seasonal Sand Mining Operation | Challenge: A contractor needed a flexible system for a 6month dredging project on a riverbank. | Solution: Used a rental MTC system with a floating feed hopper. | Results: Setup time was 2 days vs. 2 weeks for a fixed system; full system removal was completed in 1 day; zero environmental impact to the riverbank.

8. FAQ

Q: How does the MTC system handle wet or sticky sand?
A: The variable speed apron feeder and rubberlined impact beds prevent material buildup. For extremely sticky claybound material, optional belt scrapers and a heated belt cleaner are available.

Q: Can this system integrate with my existing crusher?
A: Yes. The discharge height and belt speed are adjustable to match any standard crusher feed bin or grizzly. A transition chute can be customengineered for your specific crusher model.

Q: What is the typical payback period for this equipment?
A: Based on field data from 40+ installations, the average payback period is 1218 months when replacing 3 or more haul trucks. This is driven by fuel, labor, and maintenance savings.

Q: How many operators are required to run the system?
A: One operator for the feed end (loader/excavator) and one for the control panel. The system can be run semiautonomously after setup.

Q: What happens if a conveyor section gets damaged?
A: The modular design allows for a single section to be disconnected and replaced within 24 hours. We stock common components (rollers, belt sections, drive motors) for immediate shipment.

Q: Is the system suitable for rental or shortterm projects?
A: Yes. We offer rental units with monthly terms and a guaranteed buyout option. The system is designed for rapid deployment and teardown, making it ideal for 312 month projects.

Q: What maintenance is required daily?
A: A 15minute walkaround inspection: check belt tension, grease all bearings (if no central system), inspect scrapers, and verify tracking. Full oil and filter changes are required every 500 hours.
