1. Product Introduction
The NE50 Plate Chain Bucket Elevator is a standard model within the renowned NE series. It is a high-efficiency vertical conveying machine designed for medium to high throughput. By utilizing advanced “flow-in” feeding technology (as opposed to traditional scooping methods), this elevator represents a significant upgrade from legacy models such as the HL ring chain elevators -2-8.
It is widely used in the mining, metallurgy, building materials, chemical, and grain industries for vertically lifting powdery, granular, and small block materials.
2. Working Principle
The NE50 operates on the principle of gravity-induced discharge.
- Feeding: Materials flow directly into the hopper through the inlet chute (self-feeding), eliminating the need for forceful digging. This reduces power consumption and wear on the components -5-8.
- Conveying: A motor drives a hard-tooth reducer, which turns the head sprocket, pulling the high-strength alloy steel plate chain. The chain carries the hoppers upward at a low speed (typically 0.5 m/s) -1-3.
- Discharging: When the hopper reaches the top head sprocket, the material falls out due to gravity combined with centrifugal force, ensuring high efficiency with very low backflow (rebound) -5.
3. Key Features & Advantages
- High Conveying Capacity: The NE50 offers a standard lifting capacity of 50–60 m³/h (depending on material density). The large capacity hoppers (15.7L) are arranged densely to maximize throughput -1-4.
- Low Energy Consumption: Compared to traditional TH or HL type elevators, the NE50 can save approximately 30% of energy due to the “no-rebound” feeding principle and low chain speed -5-7.
- Durable & Long Life: The traction component is a high-strength alloy steel plate chain (double-strand for NE50). It features carburizing and quenching treatment, making it highly wear-resistant and reliable for heavy loads. The casing is fully sealed and pressed with ribs for high rigidity -1-5-8.
- Wide Application Range: It can handle materials with a temperature of up to 250°C and a block size of up to 50mm (Note: max size depends on the percentage of large blocks) -2-8.
- Environmentally Friendly: The fully sealed casing prevents dust leakage and environmental pollution, meeting modern industrial standards -1-2.
