•  Large conveying capacity

The series is of elevators with similar structure size and the largest conveying capacity among similar domestic elevators with conveying capacity of 70-2000m³ /h.

• Low Drive Power

Subject to flow- through feeding, induced unloading, and intensive layout of hopper with large capacity. There is no back feeding or material excavation at the time of elevating materials, thus there is a little reactive power. It saves 30% power than ring chain bucket elevator.

• Long Service Life

Elevator is subject to flow-through feeding. It is unnecessary to excavate materials with hopper. Avoid any squeeze or collision phenomenon between materials. A little sprinkle at the time of feeding, elevating and unloading is guaranteed in design of the elevator, which reduces mechanical wear. High strength and wear resistant conveying chain is used on Board chain, which greatly prolong service life of chain and bucket. In normal cases, service life of conveying chain are more than 3 years.

•  Higher Lifting Height

The series of elevator has no hopper for material excavation, which is stably operated and subject high intensity board chain, thus it can reach higher lifting height and can be lifted to be no more than 55m under rated conveying capacity.

• Wide Lifting Range

The kind of elevators has a few requirements for categories and features of materials, which can be used to lifting powdery and granular materials as well as materials with high abrasiveness and temperature of no less than 200℃.

• Good Operational Reliability

Advanced design principles and machining method ensures the reliable operation of entire conveyor, easy operation and convenient maintenance, and a few vulnerable parts. Moreover, mean time to failure is more than 20,000 hours.

• Good Structure Rigidity and

High Precision

The casing has high rigidity and beautiful appearance after being subject to edge-fold, middle belling, and welding.

• Sealing well

Low environmental pollution

• Low Comprehensive Costs

It has low cost of use due to energy conservation and less maintenance.

1

NSE board chain elevator is constituted by operating components, drive devices, head devices, middle casing, and tail devices.

2

Operating components-consisting of hopper and sleeve roller chain.

3

Drive device is constituted by drive platform and drive combination. Drive combination is directly connected：rectangular axis hardened reducer is used to be directly connected with principal axis of the elevator. Coupler is used to connect Y-series of motors with reduction gears. Users can select auxiliary rotating motor for equipment maintenance.

4

Drive device is divided into left assembly drive device, right assembly drive device, and dual drive device. So as to be respectively corresponding to left assembly elevator, right assembly elevator, and dual drive elevator.

Left assembly: personnel are face to the feed inlet, while drive device combination is on the left side.

Right assembly: personnel are face to feed inlet, while drive device combination is on the right side.

Dual drive: personnel are face to the feed inlet, while drive device combination is on both sides.

5

Head device is constituted by head casing, hood, discharge opening (with anti-back feed board), dust collection opening, head axis assembly, and other components.

6

Middle casing is divided into middle node with access door, standard middle node (with height of 3.0m), and non-standard middle node.

7

Tail device includes tail casing, feed inlet, tail axis assembly, tension device, rotation detector, and material level switch.
