2000t/h ship loading system of public filler in HK

SKE provided AAHK a new ship loading system of public filler in HK in 2018!

  • Location: Port of Tseung Kwan O, Hong Kong, China.
  • End User: AAHK (Airport Authority Hong Kong).
  • Equipment: Fixed/stationary belt ship loader system.
  • Applications: Barge/Ship Loading of public filler.
  • Raw Materials: Public filler produced from construction waste.
  • Tonnage: The Barge loading capacity is up to 2000 tph.

Public fill is mainly produced from construction, excavation, renovation, demolition and road works. It mainly comprises of rocks, concrete, asphalt, rubbles, bricks, stones and earth, and is able to be reused in reclamation and site formation. Hard materials can be recycled as aggregate for concrete/asphalt production or as granular for road sub-base and drainage layers etc.This ship loading system of public fill is used in loading sieved and recycled construction waste on board.

Introduction of this ship loader system of public fill

Implementation Standards and Specifications: China Standards, British Standards and Hong Kong Standards.

2000t/h ship loading system of public filler in HK

What is the ship loading system of public filler like?

The sieving and ship loading conveying system works continuously for 24 hours. First, the public fill is screened through a vibrating feeder, and the stones, steel bars, and wood blocks larger than 300mm are screened out. The required size material is supplied to the vibrating screen for secondary screen through a belt conveyor with width 1200mm. The size bigger than 50mm are screened out, and then the finished products are transported to the barge via two belt conveyors with width 1400mm. The finished product is transported to Hong Kong Airport via barge.

What technical problems of this ship loader system have we solved?

The screening and ship loader conveying system handles the public filler produced from construction waste, and some construction waster has a large water content and a large mud content. Therefore, each link of the system, especially vibrating feeder, vibrating screen, conveyor receiving hopper, slip tubes, wear-resistant linings, etc, should not only meet the requirements for smooth conveying of materials during operation, but also meet the requirements for impact standard for all components, and also meet materials with large water content and high mud content, which the ship loading conveyors can smoothly convey the bulk material to ensure normal blanking and smooth transportation, and no sticking, blocking and accumulation.

The whole system must be equipped with complete safety protection devices and necessary safety protection facilities to ensure the safe operation of the equipment. The working status of the safety protection device of the screening and conveying equipment of each line can be realized by the centralized control station system on the site, and can also be manually operated at one side of the machine.

What are the characteristics of this ship loading system of public fill?

1. Multi and high standards: This project implements multiple national and regional standards and specifications.

2. Strict environmental protection requirements: The conveying system of the project needs to be designed with dust collection, recovery system and dustproof system design.

3. Strict requirements for safety protection: In addition to the protection of rotating parts and pinch points conventionally required by belt conveyors, typhoon-proof design is required.

4. Strict safety protection requirements: The conveyor system needs to be equipped with deviation detector, belt slip detector, material flow detector, chute jam detector, anti-tear protection, rope switch, limit switch, position indicator switch, and the electrical design needs lightning protection & ground connecting, etc.

5. Third-party design review mechanism: including the calculation of embedded parts calculation, belt conveyor design calculation manual, control, communication and other drawings.

6. High requirement for less vibration, less noise, anti-corrosion, waterproof, anti-salt etc.

7. Steel structure flaw detection: The customer entrusts a third party to conduct steel structure flaw detection, and the quality of all inspection welds must meet the requirements stipulated by UK standards.

8. Conveying and metering function: Instantaneous flow and cumulative weight metering function and weight calibration device required;
