Time: June, 2021
Location: Dhaka, Bangladesh
Equipment: ZAP-S80 Asphalt Mixing Plant
In June 2021, the ZAP-S80 stationary asphalt batch mix plant, independently developed by ZOOMLINE, was successfully installed and commissioned in Dhaka, the capital of Bangladesh, and has officially commenced operations for local road and infrastructure projects. Procured and utilized by a renowned Bangladeshi engineering firm, this project serves as a prime example of ZOOMLINE deep engagement in the South Asian market and its contribution to “Belt and Road” infrastructure cooperation through reliable equipment.
As one of the core models in ZOOMLINE Machinery’s ZAP-S series, the ZAP-S80 stationary batch-type asphalt mixing plant is specifically optimized for the high-temperature, high-rainfall conditions and continuous, high-intensity construction scenarios typical of South Asia. Its detailed technical specifications are as follows, enabling it to precisely meet the high-standard construction requirements for municipal roads, expressways, and other projects in the Dhaka region while balancing production capacity with environmental benefits:
| Parameter Category | Specific Parameters |
| Core Capacity | Standard capacity: 80 t/h; drying capacity: 80–100 t/h, meeting the asphalt mix supply demands for continuous construction. Batch production cycle: 40–45 seconds per batch. Fully controllable and highly efficient throughout the entire process |
| Cold Aggregate Supply System | Equipped with 4 hoppers, each with a capacity of 6.5 m³ (total capacity 4 × 6.5 m³). The belt feeder has a conveying capacity of 100 t/h and features a variable-frequency speed control design with a wide speed range. Screens are installed at the top of the hoppers to prevent large chunks of material from entering, ensuring stable equipment operation |
| Drying System | The drying drum measures Φ1500 × 6600 mm and features an optimized blade geometry design, resulting in a 30% increase in heating efficiency compared to conventional equipment. It is equipped with a composite-insulated drying drum, and the support rollers are driven by a friction-driven motor and gear mechanism, ensuring stable operation and short cooling cycles. |
| Combustion System | Equipped with a high-efficiency burner from an Italian brand, it supports multiple fuels including diesel, heavy oil, and natural gas. Fuel consumption ranges from 6.5 to 7 kg/t, with a fuel injection rate of 60 to 600 kg/h. Exhaust emissions comply with international standards, featuring low NOx and SO₂ emissions, and meet Daka’s environmental construction requirements. |
| Mixing System | Features a three-dimensional mixing design with long-arm, short-shaft-diameter bidirectional mixing blades, ensuring high mixing uniformity. Asphalt is uniformly sprayed at multiple points via a pressurized asphalt pump to achieve full aggregate coverage. The discharge time is optimized to significantly improve efficiency and ensure consistent quality of the asphalt mixture |
| Dust Collection System | Features a combination of gravity-based primary dust collection and baghouse secondary dust collection, equipped with high-temperature-resistant DuPont NOMEX filter bags. Emission concentration is ≤20 mg/Nm³, meeting environmental standards. High-pressure pulse cleaning technology extends filter bag lifespan, and replacement is convenient without requiring special tools, meeting Daka’s environmental construction requirements |
| Control System | Utilizes German Siemens electrical components, Japanese Omron PLCs, and touchscreens. It features robust data processing capabilities, real-time storage of operational data, and multilingual display support. The control cabinet meets IP55 protection standards and is housed in an insulated, soundproof containerized control room, enabling it to withstand the harsh conditions of high temperatures and high dust levels at Daka sites. The system offers user-friendly operation and stable performance. |
Based on the core technical parameters described above, the ZAP-S80 asphalt mixing plant offers stable production capacity, precise gradation, and low energy consumption with environmental friendliness. It meets the demand for high-standard asphalt mix supply for urban arterial roads, expressways, and bridge pavements, and is perfectly suited to the operating conditions in the Dhaka region, which are characterized by high temperatures, heavy rainfall, high construction intensity, and strict environmental requirements.
Customized solutions tailored to the site conditions in Dhaka, optimizing equipment parameters to meet local construction needs and shortening the preparation cycle;
On-site installation and commissioning guidance by professional engineers, leveraging the advantages of modular equipment design to ensure rapid commissioning and on-schedule project progress;
Long-term after-sales and spare parts support, combined with equipment parameters designed for easy maintenance, to reduce customer operational and maintenance costs and ensure continuous, stable equipment operation.
Since the equipment went into operation, it has consistently supplied high-quality asphalt mix for municipal road upgrades and transportation infrastructure projects in Dhaka and surrounding areas, thanks to its stable production capacity of 80 t/h, precise gradation control, and environmentally friendly, efficient performance. This has effectively improved construction efficiency and pavement quality, contributing to the enhancement of the local transportation network. Thanks to its reliable performance and prompt service, ZOOMLINE Machinery has earned high recognition from the client, further solidifying its brand reputation in the Bangladeshi and South Asian markets, and continuing to contribute the strength of Chinese equipment to infrastructure cooperation between China and Bangladesh.
