Project Update: Processing reclaimed asphalt pavement (RAP) milled materials frequently poses industry challenges like bitumen adhesion, stubborn agglomeration, excessive fines, aggregate damage, and severe material plugging. To build a standardized RAP crushing and screening plant, an Inner Mongolia aggregate producer selected a custom-configured Huashengming 2PGC900×1200 double-toothed roll crusher. The complete unit has arrived on site, undergone structural alignment, and is undergoing final trial commissioning prior to full production.

Heavy-Duty Power Configuration & Equipment Parameters

Engineered specifically for sticky asphalt RAP lump disintegration and flexible crushing, the 2PGC900×1200 unit integrates high-tier drive components to sustain heavy-duty, continuous operation without jamming.

Subsystem / Feature Component Details & Operational Role
Motor Configuration Dual 75 kW Siemens Bede electric motors (high efficiency, high overload capacity)
Speed Reducers Dual Jiangsu Guomao hard-gear surface reducers (high torque, stable transmission)
Crushing Mechanism Shearing and flexible tearing principle via specialized teeth; breaks asphalt bonds without shattering virgin rock
Anti-Plugging Design Proprietary tooth profile with self-cleaning action to prevent bitumen buildup and roll clogging

Key Operational Advantages for Reclaimed Asphalt

  • Eliminates Bitumen Adhesion & Clogging: Unlike impact or jaw crushers that compress sticky RAP into impenetrable cakes, the shearing action of counter-rotating toothed rolls continuously disintegrates lumps and sheds sticky material.
  • Preserves Virgin Aggregate Gradation: Flexible shearing de-agglomerates asphalt binder without fracturing underlying natural rock particles, minimizing unwanted fine dust generation (<0.075 mm).
  • High-Value Recycled Product: The resulting recycled aggregate exhibits uniform gradation ideal for cold in-place recycling, road base backfilling, and asphalt mix production.
  • Low Maintenance & Downtime: Robust structural steel fabrication combined with wear-resistant alloy tooth teeth ensures long component life and simple ongoing maintenance.
