High-Quality Wear Resistant Spare Parts for Pulverizer

Premium Spare Parts for Feed Ultra-Fine Pulverizer: Boost Production Efficiency

1. Core Spare Parts for Feed Ultra-Fine Pulverizer

1.1 Dual-Stage Grinding Hammer Head

The main crushing part, designed to grind feed twice for finer powder.

● Material: High-strength cast steel (ZG270-500) with wear-resistant alloy welded to the tail.

● Advantages: 30% more wear-resistant than standard heads; boosts output by 15% and ensures ≥90% of shrimp feed passes 60 mesh. Balanced weight (error ≤5g) to avoid machine vibration.

● Use For: Grinding soybean meal, corn, and mineral mixes in aquafeed/livestock feed lines.

1.2 Split Wear-Resistant Ring

Works with hammer heads to boost crushing force, great for tough feeds like expanded aquafeed.

● Material: High-quality steel with wear-resistant alloy on the inner surface.

● Advantages: Split design cuts maintenance time by 50% (no full machine disassembly); lasts up to 11,000 tons for expanded/shrimp feed. Smooth surface prevents feed buildup.

● Use For: Ultra-fine grinding of expanded feed and high-mineral livestock feed.

1.3 Split Wear Plate (NM500 Steel)

Protects the pulverizer chamber and guides feed flow, avoiding uneven wear.

● Material: Laser-cut NM500 steel (hardness ≥500 HB) with alloy at key stress points.

● Advantages: Reduces powder friction by 40% (saves energy); split design lets you replace only worn sections.

● Use For: Grinding mineral-rich feed (e.g., layer feed with limestone) and abrasive materials like peanut meal.

1.4 High-Speed Drive Disk

Transmits power to keep the pulverizer running at stable speeds (2800–12,000 R/Min).

● Material: 45# steel with tungsten carbide overlay on the outer circle.

● Advantages: Resists wear from feed powder; balanced (error ≤5g) to avoid vibration and ensure even powder. Easy to install via dedicated threaded holes.

● Use For: Continuous feed production lines needing steady grinding speed.

1.5 Precision Classifying Wheel

Controls powder fineness, critical for small feed like shrimp larvae feed.

● Material: Thick steel plate (16mm) and round steel (φ14mm), laser-cut and welded.

● Advantages: Separates oversize particles (sends them back to grind) and discharges qualified powder (60–100 mesh). Anti-rust surface handles moist feed.

● Use For: Aquafeed and high-end livestock feed requiring strict fineness.

1.6 Other Essential Parts

● Feed Flow Divider Cover: Guides feed evenly into the chamber to prevent uneven hammer wear; made of food-safe steel.

● Main Shaft Assembly: High-strength 40Cr steel shaft + high-speed bearings + dust seals; ensures stable power for 24/7 production.

● Pin Discs: For ultra-fine grinding of herbal additives/probiotics in livestock feed; wear-resistant alloy steel.

2. Why Choose Our Parts?

● Feed-Specific: Not repurposed from other industries—built for feed materials.

● Long-Lasting: Wear-resistant materials (NM500 steel, alloy) extend replacement cycles by 30–50%.

● Easy Maintenance: Split designs and user-friendly features cut downtime.

● Wide Fit: Works with most mainstream feed ultra-fine pulverizer models (small 5–50 kg/h to large 5–20 T/h lines).

3. Application Scenarios

● Aquafeed: Split rings + classifying wheels ensure 60–100 mesh powder for better shrimp/fish digestion.

● Livestock Feed: Dual-stage hammer heads + wear plates handle fiber (straw) and minerals.

● Expanded Feed: Wear-resistant rings + drive disks process tough expanded feed efficiently.
