Product Specifications

Technical details and manufacturing context for Mixing Unit

Definition
The mixing unit is the central processing component within an asphalt mixing plant, responsible for the precise and uniform combination of heated aggregates, mineral filler, and liquid bitumen. It operates under controlled temperature and timing conditions to ensure the asphalt mixture achieves the required consistency, coating quality, and material properties for road construction applications.
Working Principle
Pre-heated aggregates and filler are fed into the mixing chamber. Simultaneously, precisely metered hot bitumen is sprayed into the chamber. A set of rotating paddles or blades (mixing arms) vigorously stir and lift the materials, ensuring each aggregate particle is fully coated with bitumen. The mixing action continues for a predetermined cycle time to achieve a homogeneous blend before discharge.
Common Materials
High-strength alloy steel, Abrasion-resistant steel plate, Heat-resistant seals
Technical Parameters
  • Batch capacity, defining the maximum quantity of finished asphalt mixture produced per mixing cycle. (kg/batch) Standard Spec
Components / BOM
  • Mixing Chamber / Bowl Part
    The enclosed vessel that contains the materials during the mixing process.
    Material: Abrasion-resistant steel plate
  • Mixing Shaft Part
    The central rotating shaft to which the mixing arms are attached.
    Material: High-strength alloy steel
  • Mixing Arms / Paddles Part
    Blades attached to the shaft that physically stir and lift the aggregate and bitumen.
    Material: Abrasion-resistant alloy steel (often with replaceable tips)
  • Discharge Gate
    A mechanized door at the bottom of the mixing chamber that opens to release the finished batch.
    Material: Steel with heat-resistant seals
  • Drive System
    Motor, gearbox, and couplings that provide power to rotate the mixing shaft.
    Material: Various (steel, cast iron, copper windings)
