Rotary Drum Dryer (Aggregate Dryer)

The rotary dryer is integrated with burner and baghouse dust collector. Rotating drum and flights are made of wear-resistant alloy material, while the riding ring and trunnion wheel are constructed through forging process. The external surface of the drum dryer is insulated by aluminum-silicate wool and covered with stainless steel panel to reduce heat loss and ensure high environment protection performance.

Dust Collection System

The dust collection system is installed above the drum dryer, thus greatly saving floor space while efficiently restrict the heat loss of ductwork system. The modular design of dust collection system enables the transportation and installation easier.

Vibrating Screen

The vibrating screen used in this asphalt mixing plant is Italian brand linear motion vibrating screen that uses double vibration drives, ensuring maintenance free and smooth operation. Screen mesh can be easily changed by simply pushing and pulling. The screen body has insulation layer for improved energy efficiency and noise reduction.

Mixing System

Twin-shaft paddle mixer, or pugmill mixer, utilizes two horizontal rotating shafts with several paddles to blend asphalt and aggregates in the mixing chamber. With the optimized arrangement of mixing paddles on both shafts, the mixing efficiency of the mixing system is greatly improved, while guaranteeing the reliability and stability of the mixer. Each access door has lock to ensure the safety of operator. The thermal oil jacket is provided for heat retention. There are connections for adding additives.

Burner

Our self-developed atomizing burner can achieve optimal air/fuel ratio by digital precise control of oil pressure and frequency, enabling flame dimensions to accommodate the parameters of drum therefore reducing fuel consumption. The integrated control system of burner and mixer makes operation easy, safe and reliable. Diesel, heavy oil and natural gas are applicable fuel options.

Asphalt Foaming & Warm Mix System

This system features modular design, providing easy installation. The diaphragm piston pump supplies high pressure water as foaming agent into the asphalt, and large micro-bubbles are formed when water is mixed with the asphalt. These micro-bubbles are retained throughout the mixing process until paving and compaction process, significantly reducing fuel consumption.

Control System

Dual redundancy control coupled with PLC system provides greater reliability, safety and convenience in automatic operating performance.
The control system is configured with fault warning, automatic diagnosis, real-time monitoring and remote maintenance functions to further guarantee easy and safe operation.
