Product Overview
VOTNE Concrete Mixer Side Liners are heavy-duty wear-resistant tiles engineered to line the internal side walls of twin-shaft, planetary, and pan concrete mixers, shielding the steel mixer housing from turbulent cement slurry scour and aggregate impact.
While central drum liners bear the primary vertical drop forces, side liners experience continuous high-velocity slurry recirculation and aggregate wedging along plate joint seams. If low-grade steel liners are used, slurry washes behind the wall plates, causing structural shell rust and joint bleeding. VOTNE side liners utilize ultra-hard Cr20 and Cr26 high-chromium alloy casting metallurgy, forming a dense concentration of discontinuous M7C3 eutectic carbides (1500 to 1800 HV) bound inside a tempered martensitic matrix.
Designed with precision tapered edge profiles and CNC-machined countersunk bolt recesses, VOTNE side liners ensure smooth material flow, eliminate aggregate wedging pockets, and deliver up to 3 times longer service life than standard iron plates.

Key Advantages for Plant Operators
Tapered Anti-Wedging Edges
Precision tapered edge profiles eliminate slurry pockets between adjacent side tiles, preventing aggregate wedging and shell corrosion.
Superior Resistance to Slurry Scour
High-density M7C3 carbides withstand continuous splash turbulence, maintaining flat side wall surfaces for smooth concrete discharge.
Flush Countersunk Bolt Fit
CNC-machined bolt recesses allow countersunk bolt heads to seat flush, protecting bolt threads from abrasive wear and shear.
Extended Replacement Intervals
Extending side liner life by up to 3x reduces maintenance teardowns and keeps your batching plant operating at peak capacity.
Standard & Custom OEM Stock
Direct replacement side liner tiles in stock for major European and Asian mixer brands, with rapid custom casting available.
Applications & Field Use Cases
VOTNE Concrete Mixer Side Liners are widely specified across industrial concrete mixing operations:
- Commercial Ready-Mix Concrete Batching Plants (Twin-Shaft Mixers 1.0m³ to 4.5m³)
- Precast Concrete Manufacturing Facilities (Planetary and Counter-Current Pan Mixers)
- Infrastructure & Dam Construction Projects (Mass concrete mixing with 40mm aggregate)
- Asphalt & Cold-Recycled Pavement Mixing Plants
- Mining Paste Fill & Underground Backfill Preparation
- Refractory & Industrial Chemical Mixing Equipment
Frequently Asked Questions (FAQ)
1. How do VOTNE side liners prevent aggregate wedging between plate joints?
VOTNE side liners feature precision CNC-machined tapered edge profiles (1.5mm to 2.0mm joint gap) that ensure tight interlocks between adjacent tiles. This prevents coarse gravel and sand micro-particles from wedging between wall seams.
2. Which alloy grade is recommended for side liners: Cr20 or Cr26?
For standard commercial ready-mix concrete batching, VOTNE Cr20 (62–65 HRC) provides long wear life. For plants mixing highly abrasive materials like crushed granite, quartzite, or iron slag, we recommend VOTNE Cr26 (63–66 HRC) for maximum resistance to turbulent slurry scouring.
3. What installation steps prevent slurry bleeding behind side liners?
Before fitting new side liners, clean the mixer housing to raw steel. Apply a continuous 3mm bead of high-tack RTV polyurethane sealant or install 2mm EPDM rubber backing gaskets behind each wall tile. Torque M16 Grade 10.9 countersunk bolts to 210–230 N·m.
4. Do you support custom OEM side liner manufacturing for older mixers?
Yes. VOTNE produces custom side liner tiles based on customer samples or 2D/3D CAD drawings. We can customize tile dimensions, bolt hole locations, and alloy compositions to match any mixer model.
5. What are your lead times and trade terms for export orders?
Standard replacement side tiles for BHS, SICOMA, and Liebherr mixers are kept in stock for immediate dispatch. Custom casting orders take 15 to 25 days. We support EXW, FOB, CIF, and DDP trade terms with global shipping.
