HSM RAP Recycling: Technical FAQ
Q1: Why is HSM’s “Shearing” principle critical for RAP quality?
Hammer or impact crushers use violent force that shatters the stone aggregates inside the asphalt. HSM toothed rollers “tear” the asphalt bond at low speeds. This preserves the original stone size and sharp angles, ensuring the final recycled mix has superior crack resistance and drainage.
Q2: How does HSM prevent asphalt from sticking to rollers in hot climates?
Clogging is usually caused by frictional heat melting the bitumen. Our machines operate at a low-rotation, high-torque state, generating virtually no heat during crushing. Additionally, the tooth profile is self-cleaning, ensuring sticky RAP passes through efficiently without downtime for cleaning.
Q3: What capacity ranges do you offer for RAP processing?
HSM Heavy Industry provides a wide range of models, with processing capacities from 20 t/h to 450 t/h. Each unit can be customized with specific hydraulic gap adjustments to produce precise 0-13mm, 13-25mm, or 25-50mm aggregates based on your recycling standards.
