Note: the parameters on this page are for reference only. The actual figures are subject to the actual configuration, and the interpretation right belongs to the manufacturer.
1. Cold feeding system
n Aggregates are conveyed by frequency-controlled feeding belt, thus ensuring a high precision primary proportion.
n Warning device prevents feeding belt running without load.
n Vibrator keeps materials from jamming the gate or clinging to the bin walls.
2. Drying system
n State-of-the-art flights ensure an even aggregate veil to facilitate heat transfer and protect the drum against wear and tear as well.
n Low-pressure atomizer enables the fuel to combust for peak efficiency.
n The burner adapts to a variety of fuels (diesel, heavy oil, natural gas), and has low noise emissions.
n The turndown ratio of burner is 10:1, which reduces energy consumption.
3. Dust removal system
n Coarse dust is collected by primary dust collector (inertial separator). Fine dust is collected by secondary dust collector (pulse jet baghouse). The reclaimed filler is able to be re-fed to the mix as needed. This German technology ensures low dust emission (less than 20 mg/Nm3).
n Temperature protection system protects filter from overheating by controlling cold air valve and burner.
4. Hot aggregate elevating system
n Double-chain bucket elevator conveys material stably and has low noise emissions.
n The buckets are made of wear resistant steel and thus have a longer lifetime.
5. Screening system
n Our inclined vibrating screen is driven by two eccentric shafts or two unbalanced motors. Both have high screening performance.
n Screen mesh is easy to replace.
n Bearing is low-maintenance.
6. Hot aggregate storing system
n The bin level indicator transmits signal to the control system timely.
n Aggregates flow out automatically through the overflow chute when the silo is full.
n Oversize aggregates drop automatically through the oversize aggregate chute.
7. Weighing system
n Mineral scales have accumulation function and automatic in-flight correction function. For large plants, we adopt the combination of double aggregate scales. The scale is accurate to within ±2.5%.
n Filler scales have 3 points of measurement and accumulation function. The scale is accurate to within ±2%.
n Bitumen scales are dual-range scales and have 3 points of measurement. The scale is accurate to within ±2%.
8. Mixing system
n The twin-shaft mixer has high mixing efficiency and low wear costs.
n The liner plates and agitator paddles are made from wear-resistant nichrome, thus ensuring a long service life.
9. Hot mixture storing system
The Loading silo is insulated. The temperature of mixed material drops no more than 5 degrees within 12 hours, when the ambient temperature range is 15—25℃.
10. Control system
Our PLC cabinet adopts Siemens components and is user-friendly. Automatic, semi-automatic and manual controls are available. The control system also has such functions: recipe storage, automatic in -flight correction, parameter adjustment, scale calibration, bitumen to aggregate ratio trace, automatic fault diagnosis, automatic alarm and sheet printing.
11. Service
Our plant is modular design. Installation, maintenance, and relocation are very convenient. Our service team is well trained to help customers with products purchase, operation, and maintenance.
