Concrete Roller Crusher crushes materials by squeezing them with two high strength alloy rollers rotating in opposite direction. After entering the gap between the rolls (V-shaped crushing chamber), the material is crushed to the target size by squeezing force, shear force and mutual friction. Discharge size is controlled by adjusting the gap between rollers (such as hydraulic or spring device automatically adjusted), and the rollers are automatically separated to protect the equipment in case of over-hard materials.

Concrete Roller Crusher
1. Concrete crusher core performance characteristics
Concrete roller crusher applicable material range
Compressive strength ≤250MPa: designed for concrete, construction waste (moisture content ≤35%), asphalt blocks, bricks and so on.
High hardness material limitation: over 250MPa need to switch to roll crusher.
Flexible and adjustable discharge size
Flat roller surface: feed <80mm, discharge 1-10mm (fine crushing).
Surfaced rollers: feed <150mm, discharge 5-30mm (medium and fine crushing).
Real-time gap adjustment by wedge bolt or hydraulic system (e.g. Huashengming 1012).
Environmental protection and low loss design
Low over-crushing rate: Extrusion + shear crushing reduces the generation of powder, and the finished product has uniform particle size (over-crushing rate <10%).
Dustproof and noise reduction: sealed structure + dustproof plate to suppress dust, noise ≤ 75dB.
Self-cleaning roller: tooth design anti-sticking material, water-containing materials are suitable (add scraper).
High energy efficiency and durability
Dual motor independent drive: support single/dual machine switching, energy consumption reduced by 15-30%.
Super wear-resistant roller skin: alloy material life 0.5-5 years, 2-3 times longer than ordinary equipment.

Concrete Roll Crusher
2. Roller crusher application scenarios and advantages
Construction waste regeneration
Crushing concrete block to aggregate grade (3-30mm), directly used for roadbed backfill or new concrete preparation.
Mobile installation (e.g. truck chassis), adapting to site space constraints.
Industry Suitability
Mining/building materials: processing of steel slag, cement clinker, granite (hardness ≤ 250MPa).
Environmental projects: low dust characteristics in line with green production standards (e.g. recycled aggregate plants).
Economic benefits
Maintenance costs reduced by 40%: modular design replaces the toothed ring in only 4 hours.
Overload protection: hydraulic spring back-off mechanism reduces downtime.
3. Suggestions for selection
Small and medium scale processing (≤ 50t/h)
Choose 2PG750×500 or 2PG800×600, taking into account the compact size and output.
Large-scale regeneration project (≥100t/h)
Huashengming 1012 double-tooth roller machine (output 150-220t/h) or CNC 1200×1500 model.
Special Environmental Requirements
No electric power scenario: diesel/petrol engine drive configuration (to be customised).
High humidity materials: confirm the equipment contains scraper anti-stick design.
