VFD for Conveyor Belt
Robust VFD drives for belt conveyors, roller conveyors, and material handling systems
Overview
A VFD for conveyor systems provides precise speed control and soft starting for belt conveyor drive applications across mining, logistics, manufacturing, and bulk material handling industries. SHZK conveyor VFDs eliminate the mechanical shock of direct-on-line starts that causes belt slippage, material spillage, and excessive wear on belts, rollers, and gearboxes. Our drives feature specialized conveyor control functions including S-curve acceleration/deceleration profiles for smooth material flow, torque boost at low speeds for heavy-load starting, multiple motor synchronization for long-distance conveyors, and anti-runback protection for inclined conveyors preventing reverse material flow during power loss. The VFD for conveyor supports communication via Modbus RTU, Profinet, and EtherNet/IP for integration with PLC-based material handling control systems. With IP20 to IP54 enclosure options and operating temperatures from -15°C to 50°C, SHZK VFDs are designed for the demanding environments of mines, quarries, ports, warehouses, and production lines. Power ranges from 0.75kW to 630kW cover everything from small packaging conveyors to large-scale mining belt systems.
Key Benefits of Using SHZK VFD for Conveyor System
- Soft start with S-curve eliminates belt shock and material spillage
- Energy saving of 20-40% by matching belt speed to material flow demand
- Torque boost up to 150% at low frequency for loaded belt starting
- Multi-drive synchronization for long conveyor systems
- Anti-runback function prevents reverse motion on inclined conveyors
- Belt speed monitoring and slip detection for predictive maintenance
Recommended Models
| Series | Power Range | Input | Output | Best For |
|---|---|---|---|---|
| AT-310 | 0.75-15kW | 1Φ220V / 3Φ220V | 3Φ220V | Small packaging conveyors, assembly line belt systems |
| AT-700 | 0.75-400kW | 3Φ380V | 3Φ380V | Industrial belt conveyors, mining conveyors, logistics sorters |
| AT-9000 | 15-630kW | 3Φ380V | 3Φ380V | Long-distance overland conveyors, heavy-duty mining belts |
Application Cases
Case 1: Coal Mine Belt Conveyor — A coal mining operation installed SHZK AT-700 VFDs on their 2 × 160kW main belt conveyor. The S-curve soft start eliminated belt tearing incidents that previously cost ¥50,000 per occurrence in belt replacement. Speed synchronized to coal flow sensors, reducing conveyor energy consumption by 30% during partial-load operation.
Case 2: E-commerce Warehouse Sorting System — A logistics center deployed SHZK AT-310 VFDs across 50+ conveyor segments in their automated sorting facility. Individual speed control for each zone enabled precise package spacing and routing, increasing throughput by 25% while reducing motor wear and maintenance downtime by 40%.
Case 3: Cement Plant Inclined Conveyor — A cement plant utilized SHZK AT-700 with anti-runback function on their 45° inclined conveyor (90kW). The drive prevents material rollback during emergency stops and provides controlled full-load restarts, eliminating the previous problem of conveyor jamming that required manual material clearing after each power interruption.
