Product Introduction
The road cold recycler, also referred to as cold recycling mixer equipment, is a tractor three-point hitch mounted heavy-duty construction attachment designed for full-range subgrade treatment and old pavement renovation. This series includes the compact 1.8-meter road mixer (WLB1800) and wide-format 2-meter mixer (WLB2000), plus a deep-cut 1800-50 deep version for heavy construction demands. As professional cement road renovation machinery, it crushes aged asphalt and concrete pavement on-site, mixes waste aggregate with lime or cement to form brand-new stable subgrade layers, greatly cutting raw material and transportation costs for road projects. Equipped with heavy cast rear axle, reinforced differential and thick alloy cutter assembly, it adapts to municipal, rural and farm road construction worldwide.

Core Competitive Advantages
Multi-Specification Matching: The 1.8-meter road mixer fits narrow village roads, while the 2-meter mixer improves efficiency on wide municipal branch roads, with an extra deep-cut model for thick subgrade reconstruction.
High Hardness Alloy Cutter System: 20# native alloy bullet tips and forged tool holders resist abrasion when crushing hard cement pavement and gravel. Each cutter is independently bolted for partial replacement to reduce maintenance expense.
Heavy-Duty Rear Axle Power Unit: Cast steel rear axle and reinforced differential sustain continuous high torque without overheating during all-day cold regeneration work.
Fully Enclosed Sealed Cabinet: Thickened manganese steel housing prevents mixing material splashing, saving lime and cement raw material waste.
All-Working-Condition Adaptability: One machine completes cold regeneration, lime soil mixing, subgrade crushing and farmland soil improvement, realizing multi-purpose construction value.
Wide Application Fields
Old Pavement Cold Regeneration
Crushing and on-site mixing of aged asphalt and cement roads, the core application of this cold recycling mixer equipment.
Municipal & Rural Road Base Construction
Two-ash gravel, water-stable layer and cement-stabilized soil mixing for village roads, factory yards and parking lots.
Soft Subgrade Treatment
Farm passage foundation hardening, land leveling and saline-alkali soil improvement.
Cement Road Renovation
As dedicated cement road renovation machinery, it efficiently breaks worn cement pavement and recycles materials for new subgrade paving.
Common Customer Fault Solutions
1.Cold recycling mixer equipment mixing drum stalls during cement pavement crushing Solution: Cut tractor power off, clear large concrete blocks jammed between cutters; check rear axle gear oil level and refill heavy anti-wear lubricant; adjust drive chain tension to eliminate slack.
2.1.8-meter road mixer delivers inconsistent mixing depth on undulating subgrade Solution: Calibrate the floating front scraper's buffer springs to fit ground fluctuations; inspect tractor hydraulic lifting cylinder for oil leakage and replenish hydraulic fluid timely.
3.Road cold recycler triple drive chain jumps teeth under long-hour heavy mixing Solution: Replace overstretched worn chain segments with thickened heavy-duty chains; calibrate chain tension to avoid excessive sagging and tooth jumping.
4.Alloy cutter tips wear rapidly when crushing old cement pavement Solution: Slow tractor forward speed to reduce impact overload; stock spare alloy cutter assemblies for batch replacement and regularly clear stone debris around the mixing roller.
5.Rear axle generates abnormal knocking noise during continuous cold regeneration work Solution: Drain contaminated old gear oil and inject high-viscosity anti-wear lubricant; disassemble to inspect worn differential gears and replace damaged components immediately.
