INVT’s variable frequency solution for mining belt conveyors adapts to heavy-duty and harsh working conditions through adaptive intelligent control.Master-slave coordination and heavy-duty starting technologies ensure stable operation of belt conveyors. Combined with intelligent operation and maintenance, it helps customers achieve stable and energy-saving equipment performance, safety and reliability, as well as cost reduction and efficiency improvement.
Risk to production continuity: As a continuous conveying equipment, any failure of the belt conveyor will interrupt the entire transportation line, directly affecting ore crushing and grinding processes.
Multi-machine coordination and operating condition adaptability: Long-distance belts often adopt multi-machine drive, resulting in poor load balance among multiple motors and causing individual motors to burn out due to overload.
Poor power grid environment: The mine power grid is unstable, especially in remote mining areas; voltage dips lead to VFD shutdowns, which easily trigger heavy-duty stoppage or reversal accidents.
Erosion from harsh operating conditions: High dust, corrosion, extreme cold, high temperature and humidity cause equipment aging and insufficient operational stability.
Pain points in operation and maintenance management: Monitoring points of long-distance belts are scattered, leading to long inspection times and low fault location efficiency.
Featuring the INVT GD5000 series medium-voltage VFDs as the core, the solution adopts optical fiber ring network and master-slave control to realize precise multi-machine power coordination.Supported by low-frequency heavy-duty starting and three-proof design, it ensures reliable operation under extreme working conditions.Equipped with multiple safety protections and intelligent O&M functions, combined with full-life-cycle services, it enables stable, energy-saving, safe and efficient operation of belt conveyors.
View Larger ImageRigidity & Flexibility in Balance: Supports multiple master-slave control modes. Torque control or droop compensation strategies can be selected for rigid and flexible connections to achieve balanced load distribution.
"Ultra-Long-Distance Fiber Optic Ring Network": Supports long-distance fiber optic communication over 6 km. The ring network ensures millisecond-level signal response, meeting the coordinated control requirements of the head and tail of ultra-long belts.
“Full-Link Safety Protection”: Integrates slip protection, belt breakage capture interlock, speed anomaly detection and STO safety torque off. It realizes millisecond-level coordination between electric braking and mechanical braking, preventing overspeed and reverse rotation.
“Three-Proof & One-Durability Design”: Independent air duct + three-proof paint coating + wide-temperature components, effectively resisting dust, moisture and acid mist corrosion to extend equipment service life.
“Pre-Diagnosis”: Monitors the operating status and life attenuation trend of IGBT modules, electrolytic capacitors and cooling fans in real time, and realizes remote condition monitoring and fault diagnosis via the cloud platform.
The "automatic bypass for faulty units" technology eliminates unplanned downtime caused by VFD failures and improves production efficiency.
Fiber-optic communication with millisecond-level synchronous response and power balancing accuracy of ≤5% extend the service life of motors and reducers, significantly reducing annual maintenance costs.
High-protection design standard for drives helps prolong VFD service life and reduce failure rate by 80%.
Integrated full-link safety protection prevents belt breakage and runaway accidents, ensuring the safety of personnel and equipment.
The pre-diagnosis system enables real-time monitoring and rapid fault location and diagnosis, avoiding production losses and reducing unplanned downtime.
