Asphalt Plant

 

Main Asphalt Plant


Anderson's main asphalt plant is located at Lam Tei Quarry, Tuen Mun, Hong Kong. It is a DGM 1500T190, 1.5-tonne-batch, rated output one hundred twenty tonnes per hour Asphalt Batching Plant.

The plant is capable of producing mixes using all-virgin materials, or with the incorporation of RAP (Reclaimed Asphalt Pavement).

Flow of virgin aggregates comprises five cold feed bins having volumetric belt feeders, a rotary dryer, multi deck inclined vibrating screens, five hot aggregate bins, and four weighing hoppers (bitumen, added or reclaimed filler, aggregates and RAP).

Flow of granulated RAP comprises a cold feed bin having volumetric belt feeder, a feeding conveyor, a fully insulated surge bin, and screw conveyors which feed RAP to weighing hopper.

Batching is completed with a 1.5-tonne capacity pugmill which discharge product mixes into two hot mixture storage bins (fully insulated and heated cones and doors, total storage capacity of one hundred forty tonnes) via drag conveyor.

Other main facilities include a pollution control system complying with the licensing requirements of the Environmental Protection Department. Batching is automatic and recorded. Temperature controls are located at various parts of the plant including on dryer discharge, hot aggregate storage bin, bitumen storage, and exhaust stack. Molten binder is delivered into hot oil-heated and insulated storage tanks. Automatic cut-out controls limit the binder temperature from exceeding specified limit.



New State of the Art Facility


In early 2024, a fully automated, state-of-the-art green asphalt plant will be built on a new site at Sai Tso Wan Road, Tsing Yi Island. Using selective catalytic reduction of nitrogen, it will be the most advanced asphalt plant in Hong Kong with sophisticated control measures for both dust and NOx. It will also have the capacity to store and recycle asphalt pavements, saving up to 50% of the raw materials.



Other Production Plants


Anderson has other production plant available at short notice to move to site locations as required.
