Shaanxi Roadbest is a leading asphalt mixing plant manufacturer and direct factory supplier from China.
Our asphalt mixing plants—also called asphalt concrete batching plants—are the essential equipment for producing premium asphalt mixtures used in highways, airports, and urban roads.
Just like a kitchen prepares meals, an asphalt mixing plant “cooks” aggregates (stone, sand), bitumen, and filler into a durable, smooth road surface. This article covers functions, components, working principle, types, and modern upgrades—everything you need to know before investing in the right plant.
1. Core Functions of an Asphalt Mixing Plant
An asphalt mixing plant has one main task: to produce asphalt mixtures that meet engineering specifications. This includes:
Precise Proportioning – Aggregates, bitumen, and mineral powder are weighed according to the design formula.
Heating Treatment – Aggregates are heated to 150°C–180°C for optimal coating.
Uniform Mixing – Ensures strong adhesion and consistent quality.
Environmental Compliance – Controls dust and fumes to meet green production standards.
2. Six Main Systems of Shaanxi Roadbest Asphalt Mixing Plants
2.1 Cold Aggregate Supply System
Stores and delivers different sizes of aggregates via steel hoppers and feeders.
2.2 Drying & Heating System
A rotating drum dryer heats aggregates using diesel, natural gas, or heavy oil burners.
2.3 Dust Removal System
Pulse bag filters capture dust, keeping emissions ≤ 20 mg/m³.
2.4 Weighing & Batching System
High-precision scales ensure ±0.5% accuracy for each ingredient.
2.5 Mixing System
A twin-shaft compulsory mixer blends aggregates, bitumen, and filler at 140°C–160°C.
2.6 Finished Product Storage & Delivery
Insulated silos keep asphalt hot before being transported in specialized trucks.
3. Working Process
- Aggregates enter the dryer from cold aggregate hoppers.
- Burner heats and removes moisture.
- Hot aggregates are screened by vibrating screen and stored in assigned hot bins.
- Hot aggregates, bitumen and mineral powder are measured in weighing layer.
- All ingredients are mixed in the twin-shaft mixer.
- Finished asphalt mix is stored or loaded for paving.
