If you’re in the farm silage feed industry looking for durable, high-performance mixer knives, Yafei® is your trusted partner. With decades of experience in agricultural equipment manufacturing, Yafei® has built a global reputation for excellence in both OEM ag parts and aftermarket farm equipment components. Our flagship product—Yafei Knives™ silage mixer blades—outperforms competitors in durability, cutting efficiency, and cost-saving value, making it a top choice for farms of all sizes.

Blade body: Made of 50CrV4 high-carbon steel with quenching and tempering treatment (hardness: HRC 52-55), ensuring strong impact resistance for daily silage mixing.

Cutting edge: Inlaid with 99.5% pure ultra-fine grain tungsten carbide (WC-Co alloy), 8-10x more wear-resistant than regular carbon steel blades—perfect for handling tough silage fibers.

Best For: Small to medium-sized farms processing 50-150 tons of silage daily. Routine feeding for dairy cows, beef cattle, and other livestock.

2. Yafei High-Performance Silage Mixer Knives: Patented Technology for Large-Scale Operations

Equipped with Yafei’s patented nano-grade carbide coating (Patent No.: ZL 201623589lA)—coating thickness controlled at 8-12μm for uniform protection.

Dual-metal structure: Blade body uses 42CrMo alloy steel (toughness) + cutting edge with WC-TiC composite carbide (hardness)—no chipping or edge rolling during continuous use.

30% faster cutting speed than standard blades; reduces single mixing time by 15-20 minutes.

Service life: 400-600 hours (2.5-3.5 longer than ordinary blades)—cuts downtime for blade replacement.

Hard-to-process silage (high-fiber alfalfa, whole-plant corn silage).

Triangular serrated pattern with 5mm precise tooth spacing; tooth tip hardness reaches HRC 60-62.

“Bite + shear” dual action: Eliminates slipping or material wrapping common with flat blades—tears through thick silage bundles easily.

Serrated parts use powder metallurgy high-speed steel (PM HSS) combined with carbide inlay—40% higher fatigue resistance.

Works reliably in -10℃ to 5℃ low-temperature environments (ideal for cold-region farms).

Farms in cold areas or processing high-moisture silage (over 65% water content).

Upgrading old mixers to restore efficiency.

1. Lower Fuel Costs: Sharper blades reduce mixer load resistance. Third-party tests show 8-12% less fuel per ton of silage—for a farm processing 100 tons/day (diesel at \(1.10/L), that’s **\)2,400-$3,600 in annual savings**.

2. Faster Processing: Cut 20 tons of whole-plant corn silage in 45 minutes (standard blades) or 35 minutes (high-performance blades)—critical for avoiding silage spoilage during peak harvest seasons (September-November).

3. Less Maintenance: Long service life + Yafei’s old blade recycling program (10% discount on new blades when you return used ones). Anti-corrosion coating resists acid silage (pH 3.8-4.5), reducing mixer breakdowns.

Raw Material Testing: Spectrometer checks steel and carbide composition—100% compliance with industry specs.

Precision Manufacturing: CNC grinding machines ensure ±0.02mm accuracy; nitrogen-protected coating prevents oxidation.

200-Hour Simulation Test: Blades are tested in real silage conditions to verify wear resistance and fatigue strength—defective products are discarded.
