Engineered for extreme mining conditions, the mining conveyor features ST6300 steel-cord belts (width: 1.4-2.2m) with rip detection sensors. Fire-resistant covers (ISO 340 compliant) and anti-static idlers ensure underground safety, while 45° incline capabilities handle steep pit walls. Critical mining adaptations include:
Impact zones: Triple-row idlers + rubber cushion beds
Drive systems: 1,000 kW dual-drum motors with fluid couplings
Dust control: Air cannons + enclosed galleries
Capable of 8,000 TPH copper ore transport over 15km distances, these conveyors reduce haul truck fleets by 70% in open-pit operations.

Key Features
High Capacity and Long Distance
Comprehensive range of belt widths; speeds of 0.8–5.0 m/s; single-unit lengths up to several kilometers; conveying capacity exceeding 6000 t/h-meeting the needs of centralized transport in large-scale mines.
01
Flame-Retardant and Anti-Static (Coal Mine Safety Compliant)
Uses flame-retardant, anti-static belting materials and explosion-proof electrical components; the entire unit and underground components hold the MA safety certification.
02
Extendable and Relocatable (Adapts to Changing Roadways)
Extendable models feature a tail section that moves automatically with the advancing working face and extends/retracts as needed; suitable for fully mechanized mining/excavation roadways and applications with varying transport distances.
03
Stable operation and low maintenance costs
Features a simple structure and highly interchangeable components; there is virtually no relative movement between the material and the belt, resulting in minimal wear and low energy consumption.
04
Intelligent control and centralized monitoring
Can be equipped with PLCs and sensors to enable automatic speed adjustment, fault diagnosis, and remote monitoring; supports variable-frequency soft starting and automatic hydraulic tensioning.
05
Applications
Underground coal mines: Main haulage roadways, gate roads for fully mechanized mining/tunneling; extendable and relocatable systems.
Open-pit mines and coal preparation plants: Material transfer, raw coal and product transport.
Metal and non-metal mines: Transport from mining face to processing plant, waste rock disposal.
Ports and power plants: Bulk material stockpiling, reclaiming, transfer, and loading/unloading.
Frequently Asked Questions (FAQ)
FAQ
Q: What is the recommended frequency for routine maintenance of the mining conveyor?
A: Maintenance should be scheduled on a per-shift, weekly, and monthly basis: inspect the belt, idlers, and tensioning system during every shift-monitoring for abnormal noises, belt mistracking, and temperature-and clear away debris during shutdowns; check for seized idlers weekly; and inspect lubrication and safety protection systems monthly.
Q: How long does the installation and commissioning of a mining conveyor typically take?
A: It depends primarily on the conveyor length and site conditions (such as the underground environment). Typically, a 600-meter conveyor takes about 10 days to install, while one exceeding 2,600 meters takes approximately 17 days.
Q: Can the mining conveyor operate in high- or low-temperature environments?
A: Yes, but specific configurations are required. Heat- or cold-resistant belts and compatible lubricants must be selected, and heat dissipation or freeze protection for the motor and gearbox must be enhanced; additionally, heavy-load "cold starts" are strictly prohibited in low-temperature conditions.
