Product Introduction
The WLB2000 cold recycler is a heavy-duty tractor three-point hitch mounted road cold recycling machine with a 2000mm full-width working surface, designed for large-volume pavement renewal and subgrade stabilization projects. It is upgraded as enhanced full hydraulic cold recycling equipment with an enlarged mixing roller and reinforced transmission system, acting as a powerful old highway road recycler for major highway renovation and standard subgrade recycling mixing equipment for thick-layer foundation treatment. Matched with tractors over 90 horsepower, this model features a maximum loose mixing depth of 45cm and a compacted finished depth of 25–30cm, handling large-area continuous construction to boost daily project output significantly.
Material & Structural Specification
Reinforced Sealed Cabinet: Thickened Q345 manganese steel plate forms the fully enclosed mixing box, resisting impact from broken pavement fragments and preventing stabilizer splashing loss.
Oversized Mixing Roller: 245mm diameter heavy roller fitted with 51 sets of modular 20# native alloy bullet cutters, each cutter independently bolted for quick single-piece replacement.
Heavy Cast Steyr Rear Axle Assembly: Brand-new integral cast rear axle and heavy differential deliver sustained high torque without overheating during all-day continuous operation.
Triple Reinforced 20A-3 Drive Chains: Three parallel heavy-duty chains evenly share mixing load to avoid chain stretching and tooth jumping on hard gravel subgrade.
Adjustable Spring Floating Scraper: Dual spring buffer scraper closely fits undulating ground to maintain consistent mixing depth across wide construction sections.
Wide Application Fields
Old Highway Cold Regeneration
Large-scale aged asphalt and concrete highway renovation, the core usage of this old highway road recycler.
Municipal Main Road Subgrade
Wide urban trunk roads, industrial park parking lots and logistics yard thick-layer stabilized soil mixing.
Rural Wide Village Highway
Two-lane country road lime soil base paving and farmland hardened passage construction.
Land Consolidation & Soil Improvement
Large-area saline-alkali soil neutralization and farmland deep loosening mixing treatment.
Factory Strength
Our factory operates a complete suite of automated production lines, featuring laser cutting machines, heavy-duty welding robots, and shot-blasting equipment. We maintain dedicated R&D and testing facilities, ensuring that every WLB2000 cold recycler undergoes a two-hour full-load operational test prior to shipment. We offer OEM/ODM customization for mixing depth, tool density, and suspension brackets, and possess a stable monthly production capacity to fulfill large-volume FCL export orders for global engineering contractors.
Common Customer Fault Solutions
1.Road cold recycling machine mixing roller stalls during thick-layer old pavement crushing Solution: Cut tractor power off, clear concrete blocks jammed between cutters; refill high-viscosity anti-wear gear oil into the rear axle; adjust triple chain tensioners to eliminate excessive slack.
2.Full hydraulic cold recycling equipment shows uneven mixing depth on bumpy wide subgrade Solution: Calibrate the tension of dual floating scraper springs to fit ground undulations; inspect tractor hydraulic lifting cylinder for oil leakage and replenish hydraulic fluid timely.
3.Subgrade recycling mixing equipment alloy cutters wear rapidly on gravel-rich old highway subgrade Solution: Slow tractor forward travel speed to reduce cutter impact overload; prepare spare alloy bullet cutters for batch replacement and regularly clear stone debris around the mixing roller.
4.Steyr rear axle generates abnormal knocking noise after long-hour continuous construction Solution: Drain contaminated old gear oil and inject fresh heavy-duty lubricant; disassemble to check for worn differential gears and replace damaged internal components immediately.
