1. Overview
The Amisy Water Drop Feed Hammer Mill is a high-performance grinding device engineered exclusively for large and medium-sized feed processing plants, poultry feed factories, and food processing enterprises. Its core innovation lies in the unique water-drop-shaped grinding chamber—a design that expands grinding space and eliminates material circulation, boosting working efficiency by 40% compared to conventional hammer mills.
By leveraging high-speed hammer collision and advanced twice strike technology, it crushes raw materials (maize, wheat, beans, peanut husks, etc.) into uniform powder efficiently. With outputs ranging from 9-26t/h, it meets the high-throughput demands of industrial-grade feed production, becoming an indispensable core equipment for scaling feed manufacturing.
2. Core Value: Why It’s a Must for Large-Scale Feed Plants
Large feed factories prioritize three key metrics: efficiency, stability, and cost control. The water drop feed hammer mill addresses these needs, delivering three irreplaceable values:
2.1 Boost Production Efficiency by 40%
The water-drop grinding chamber’s streamlined design avoids material “circulation dead zones”—a common issue in traditional cylindrical chambers where uncrushed materials spin repeatedly. This ensures every particle is struck and ground quickly, reducing grinding time by 30% and increasing hourly output to 26t/h (for the AMS-ZW-50C model).
2.2 Ensure Stable Operation & Reduce Downtime
- Automatic Feeding: Equipped with an automatic feeding device that adjusts material supply in real time, preventing motor overload caused by uneven feeding—ensuring the machine runs under rated load 24/7.
- Low Vibration: A rigid pedestal and balanced rotor design minimize vibration, reducing wear on key components (bearings, hammer blades) and lowering failure rates by 50% compared to ordinary mills.
2.3 Cut Long-Term Operational Costs
As an internationally advanced energy-saving device, it achieves high output with low power consumption (e.g., 55KW for 9t/h output). Additionally, the flexible push-pull door design simplifies sieve replacement and chamber cleaning, reducing maintenance time by 40% and labor costs.
3. Working Principle: Efficient Crushing via Water-Drop Design & Twice Strike Technology
The mill’s superior performance stems from its integrated “feeding-grinding-discharging” system, which optimizes every step of the crushing process:
- Automatic Feeding: Raw materials are fed from the top feeder, distributed evenly to the grinding chamber via bilateral feeding plates—avoiding one-sided wear of hammer blades.
- Twice Strike Grinding:
- Primary Strike: High-speed rotating hammer blades (linear velocity 86.5m/s) impact large materials, breaking them into coarse particles.
- Secondary Refining: Coarse particles are further sheared and ground between the hammer blades and screen plates, with the water-drop chamber guiding materials to the strike zone repeatedly—ensuring uniform fineness.
- Air-Driven Discharge: Crushed powder is pushed out by forced air circulation (42-102m³/min, adjustable for coarse/fine grinding), preventing blockages and ensuring smooth material flow.
4. Core Features & Advantages
4.1 Innovative Water-Drop Design
- Space Expansion & Efficiency Boost: The water-drop grinding chamber provides 20% more internal space than cylindrical chambers, eliminating material circulation and improving efficiency by 40%.
- Compact & Aesthetic: Streamlined structure reduces floor space by 15%, fitting seamlessly into dense industrial production lines while maintaining a neat appearance.
4.2 Advanced & Reliable Performance
- Twice Strike Technology: Two-stage grinding ensures powder fineness uniformity (CV ≤8%), meeting the strict requirements of high-end poultry and aquatic feed.
- Energy-Saving & High-Capacity: Adopts international energy-saving motor configurations, with a “high output vs. low power” ratio—e.g., the 160KW AMS-ZW-50C model achieves 26t/h output, 30% more efficient than peer products.
4.3 User-Friendly & Easy Maintenance
- Flexible Sieve Replacement: A variety of sieve sizes are available (customizable for 0.5-5mm fineness); the push-pull door allows sieve changes in 5-10 minutes without professional tools.
- Automatic Feeding Adjustment: The smart feeder adapts to material moisture and hardness, ensuring stable motor operation and avoiding burnout from overload.
4.4 Wide Application Range
Specialized in coarse grinding of raw materials for large/medium-sized poultry feed plants (chicken, duck, goose feed) and food processing enterprises. It also handles agricultural by-products (husks, peanut shells) for ruminant feed, supporting multi-scene production.
5. Operation & Maintenance Guidelines
5.1 Safe Operation Cautions
- Pre-Start Preparation: Check that the grinding chamber is free of residual material, and confirm the automatic feeder and sieve are installed correctly.
- Start-Up Sequence: Turn on the main motor first, then activate the automatic feeder—avoid starting with a load to protect the motor.
- Abnormal Handling: If unusual noise or vibration occurs, stop feeding immediately, shut down the machine, and inspect for loose hammer blades or blocked sieves before restarting.
5.2 Routine Maintenance
- Daily: Clean the screen plates and feeding plates to avoid powder buildup; check hammer blade wear.
- Weekly: Inspect the rotor balance and add lubricating oil to bearings (use 3# lithium grease) to ensure low-temperature operation.
- Monthly: Replace worn hammer blades (when edge wear exceeds 8mm) and damaged sieves to maintain grinding efficiency.
