The precise engineering and robust mechanical standards ensure sustained output under the harshest industrial conditions.
The working mechanism of a chain bucket elevator like the NE type is based on vertical material lifting through a sequence of buckets attached to a traction chain.
Step-by-Step Operation:
Feeding: Material enters the boot section and is scooped into buckets.
Lifting: Buckets ascend vertically at 0.5 m/s; chain motion ensures smooth transport.
Discharge: At the head, buckets invert automatically; material is discharged by gravity.
Return: Empty buckets descend along the guided pathway for continuous operation.
This low-speed, high-torque system minimizes wear and ensures gentle material handling with minimal spillage.
The NE bucket elevator is widely used across various sectors including:
Cement Plants — for clinker and limestone handling.
Mining & Quarrying — for ores and bulk minerals.
Coal & Power Plants — for dry and hot coal lifting.
Fertilizer & Chemicals — for granular material transport.
Agriculture & Food Processing — for grains and feedstock handling.
Its industrial-grade strength and versatile design make it the preferred bulk material elevator for heavy-duty applications.
Scalable Capacity: Ranges from 15 m³/h (NE15) to 800 m³/h (NE800).
Compact Design: Modular construction for easy installation and maintenance.
Noise Reduction: Smooth drive reduces vibration and operational noise.
Corrosion Resistance: Anti-wear plate chain ensures stability even in harsh environments.
Advanced Sealing: IP54-rated protection against dust ingress.
Extended Maintenance Intervals: Over 20,000 operational hours between overhauls.
