CO‑NELE Heavy‑Duty Twin Shaft Asphalt Pugmill | Core Main Mixer for Asphalt Batching Plant

1. Product Overview

CO‑NELE twin shaft asphalt pugmill is the core forced mixing unit specially designed for stationary and mobile asphalt batching plants. It mixes hot aggregate, mineral powder, liquid asphalt and additives thoroughly to produce homogeneous hot‑mix asphalt mixture. Different from ordinary industrial mixers, CO‑NELE asphalt pugmill adopts heavy‑duty twin‑shaft counter‑rotating stirring structure, which effectively eliminates material segregation and guarantees consistent mixture quality for highway, municipal and airport pavement construction. The performance of CO‑NELE pugmill directly determines the finished quality and output capacity of the whole asphalt mixing station.

2. Core Advantages & Key Features of CO‑NELE Asphalt Pugmill

• Zero dead‑zone twin‑shaft forced mixing, high homogeneity of hot‑mix asphalt
• High‑chromium wear‑resistant mixing arms and blades, long service life, easy replacement
• Integral cast steel bearing seat, good sealing performance against asphalt leakage and dust intrusion
• Heavy‑duty reducer matched for continuous high‑temperature heavy‑load working conditions
• Modular structure, convenient inspection, maintenance and spare‑parts replacement
• Multiple volume options, perfectly matched with different rated output of asphalt batching plant
• CO‑NELE full‑set engineering support for model selection, site adaptation and after‑sales service

3. Working Principle

After hot aggregate, mineral powder and heated asphalt are accurately metered and fed into the mixing chamber of CO‑NELE asphalt pugmill, two parallel counter‑rotating shafts drive multiple groups of mixing arms and blades. Materials obtain compound movement of shearing, flipping and kneading inside the closed tank. Within the preset mixing cycle, all components are fully blended into qualified hot‑mix asphalt before discharging from the bottom gate.

4. Matching Between CO‑NELE Twin Shaft Asphalt Pugmill and Asphalt Batching Plant Output

Different capacity of CO‑NELE twin shaft asphalt pugmill is designed to match different rated output of asphalt batching plant. The pugmill chamber volume defines single‑batch mixing weight, which directly restricts the hourly throughput of the whole asphalt plant. Selecting undersized or oversized pugmill will cause over‑loading risk or low mixing efficiency. CO‑NELE provides a complete series of pugmill models covering 50‑400t/h asphalt batching plants. Our engineering team recommends suitable volume according to your design capacity, mixing cycle, raw‑material property and continuous‑operation requirements.

Note: Above data is for reference only. CO‑NELE engineers will optimize actual configuration based on working condition, mixing cycle and asphalt mixture formula.

5. Application Scope

CO‑NELE twin shaft asphalt pugmill is widely applied for stationary and mobile asphalt batching plants, serving various road‑construction projects:

• Expressway and national‑highway pavement construction & maintenance
• Municipal urban road, square and community road projects
• Airport runway and port pavement engineering
• Large‑scale infrastructure road projects
• Asphalt mixing station upgrading & old‑pugmill replacement

6. Frequently Asked Questions

Q1: What is an asphalt pugmill used for?

A: CO‑NELE asphalt pugmill is the core forced mixing unit inside asphalt batching plant. It mixes hot aggregate, mineral powder and hot asphalt to produce qualified hot‑mix asphalt mixture for pavement construction.

Q2: Why choose twin‑shaft structure for asphalt pugmill?

A: Twin‑shaft counter‑rotating mixing eliminates mixing dead zones, achieves high mixture homogeneity, adapts to high‑temperature heavy‑load continuous operation, which is the mainstream solution for modern asphalt batching plants.

Q3: How long is the service life of CO‑NELE asphalt pugmill wearing parts?

A: Mixing arms and blades adopt high‑chromium wear‑resistant castings. Service life depends on raw‑material abrasiveness and daily maintenance. CO‑NELE supplies full‑range spare‑parts globally.

Q4: Can CO‑NELE pugmill be used to upgrade existing old asphalt mixing plant?

A: Yes. We can provide adaptive modification solution for retrofitting and replacement according to your original plant parameters.

Q5: How to select CO‑NELE twin shaft asphalt pugmill for my asphalt batching plant?

A: Different CO‑NELE twin shaft asphalt pugmill with different chamber volumes matches different hourly output of asphalt batching plant. Model selection mainly depends on plant design hourly capacity, single‑batch weight and continuous‑operation requirements. Send your project parameters to our sales engineer for professional matching recommendation.
