As the primary entry point for raw materials into the crusher, the feed tube endures constant high-velocity impact from rocks, ores, and recycled aggregates—making wear resistance its defining requirement. Crafted from high-chrome cast steel with strategic tungsten carbide inserts in high-impact zones, this feed tube extends service life while optimizing material distribution. Its vibrant green color isn’t just aesthetic; it enhances visibility during routine inspections, allowing maintenance teams to quickly assess wear patterns without disassembly. The precision-machined internal geometry ensures uniform material flow into the rotor, eliminating uneven loading that causes vibration, bearing stress, and premature component failure.
Material Composition: Constructed from high-chrome alloy with 26% chromium content for base strength, augmented by tungsten carbide inserts (WC content ≥85%) in the material entry zone. This combination delivers surface hardness up to 62 HRC—harder than most natural rocks processed in VSI crushers.
Dimensional Range: Custom-engineered for Metso Barmac VSI models including B7150SE, B9100, and B10500, with inner diameters ranging from 200-400 mm and overall lengths up to 1,200 mm to match crusher throughput capacities.
Weight Variation: From 50 kg (110 lb) for compact B7150SE models to 180 kg (397 lb) for heavy-duty B10500 crushers, ensuring structural stability under high-volume material flow.
Environmental Resistance: Withstands continuous operating temperatures up to 300°C (572°F), critical for processing hot recycled asphalt pavement (RAP) or freshly crushed volcanic rock.
Installation Compatibility: Direct drop-in replacement for original Metso Barmac feed tubes (part numbers including B96334120A), featuring pre-drilled mounting holes for seamless integration without modifications.
Tungsten carbide inserts in the material impact zone create a hard, wear-resistant barrier that extends service life by 30-50% compared to standard steel feed tubes. In aggregate production testing, this reduced replacement frequency from every 400 operating hours to 600-700 hours .
The high-chrome matrix resists micro-abrasion from silica-rich ores and recycled concrete, maintaining structural integrity even when processing materials with Mohs hardness up to 7.
Computational Fluid Dynamics (CFD)-optimized internal contours minimize turbulence, ensuring uniform distribution of material into the rotor. This reduces fines generation by 15-20% by preventing over-crushing of already small particles .
A polished surface finish (Ra ≤3.2 μm) prevents material adhesion, critical for handling moist clay-rich feedstock or sticky ores that typically cause blockages.
The bright green powder-coat finish allows visual wear assessment from a distance, with color-coded wear indicators that change hue as material thins—eliminating the need for disassembly during inspections.
Modular segment design enables replacement of only worn sections (e.g., the entry cone) instead of the entire tube, reducing spare part costs by up to 40% .
Weight-matched components ensure balanced loading on the crusher frame, reducing vibration by 12-18% and extending bearing life in the rotor assembly .
Aggregate Production: Essential for secondary and tertiary crushing of limestone, granite, and basalt in ready-mix concrete and asphalt production, where consistent particle shape is critical.
Hard Rock Mining: Ideal for processing quartz-rich ores (gold, copper, iron) where abrasive silica content accelerates wear on standard components.
Construction Recycling: Protects crushers processing concrete debris and asphalt, withstanding impacts from embedded steel rebar and aggregate fragments.
Industrial Minerals Processing: Ensures reliable feeding in talc, gypsum, and feldspar production, where particle size uniformity directly impacts end-product quality.
By merging advanced material science with functional design engineering, this feed tube delivers measurable improvements in uptime, product quality, and maintenance efficiency for Metso Barmac VSI crushers.
