Deepening Cold Recycling Mixer

The deepening cold recycling mixer is an upgraded heavy-duty road regeneration equipment optimized for ultra-deep subgrade mixing and old pavement renovation. Equipped with a premium mercedes axle cold recycler mixer transmission system, it delivers stronger torque output and higher load resistance than standard models. Designed as a practical small pavement recycling machine with deep-cut capability, it breaks and mixes compacted old pavement, gravel subgrade and stabilized soil in one pass. Tailored for rural old road regeneration projects, it solves the common problem of insufficient mixing depth in traditional mixers, perfectly catering to thick-layer subgrade reinforcement and full-depth road renewal demands for rural and municipal infrastructure projects worldwide.

This deepening mixer boasts unique production upgrades that benefit bulk buyers and engineering contractors greatly. Firstly, it features an extended deep mixing roller structure, supporting a maximum compacted mixing depth of 35cm, exceeding ordinary models to meet high-standard road foundation construction requirements. Secondly, the matched Mercedes rear axle undergoes precision forging and heat treatment, delivering stable torque without overheating or stalling during long-hour deep digging operations. Thirdly, upgraded thickened alloy deep-cut blades enhance impact resistance against hard concrete and compacted soil, extending service life and reducing replacement frequency. In addition, the optimized sealed box structure minimizes material splashing, cutting waste of cement, lime and other stabilizers to lower overall project costs.

We provide comprehensive global after-sales support tailored for overseas purchasers. The core Mercedes axle, deep mixing roller and transmission components enjoy a 12-month factory warranty. Our professional multilingual technical team offers 24/7 online video guidance for equipment installation, tractor matching, daily lubrication and deep-operation debugging. We maintain a complete spare parts inventory, with alloy blades, drive chains and sealing accessories delivered within 7 working days for bulk orders. Custom depth adjustment and structural optimization services are available to adapt to different regional road construction standards, ensuring flexible application in diverse working scenarios.

All deepening cold recycling mixers adopt standardized export packaging. The whole machine is fixed with anti-collision steel brackets and wrapped with waterproof and dustproof protective film, while vulnerable parts are individually packed with shockproof cotton. Fumigated solid wooden cases are used for full-container shipments to avoid extrusion and damage during long-distance sea and land transportation. We support unified container loading and batch transportation, with complete export documents provided to help buyers clear customs efficiently and shorten delivery cycles.

1. Deep mixing roller gets stuck during thick hard subgrade operation: Turn off the tractor power immediately, clean up compacted soil and large gravel blocked between blades; check the Mercedes axle gear oil level and replenish heavy-load anti-wear lubricant; adjust drive chain tension to eliminate slack and jamming.

2. Uneven deep mixing depth in rural old road regeneration: Calibrate the spring floating scraper to fit undulating road surfaces; inspect the tractor hydraulic lifting system for oil leakage and adjust the depth limiter to ensure consistent mixing thickness.

3. Alloy deep-cut blades wear excessively: Reduce the tractor's forward traveling speed to avoid overload impact; replace severely worn blades in time and clean up residual stone debris around the mixing roller before continuous operation.

4. Abnormal noise from the Mercedes axle during long working hours: Drain deteriorated gear oil completely, inject new high-viscosity lubricant, and inspect internal gears and bearings for wear to replace damaged parts promptly.
