Double-Rotor (Micro-Crushing Series) Grinders
The Double-Rotor (Micro-Crushing Series) Grinders are specially designed for high-precision crushing requirements, particularly suitable for micro-crushing with a sieve diameter of 0.5~1.5mm. The product line covers series models such as 56/66/60/68 (e.g., SFSP-S56x20, SFSP-S66x30, etc.), and is widely used in the micro-crushing of suckling pig feed, pet feed, extruded feed, fermented feed, aquatic feed, as well as the fine crushing production of grain crops such as corn flour, wheat flour, sorghum flour, and cassava flour (cassava dry crushing). With its high-efficiency crushing capability and precise particle size control, it meets the diverse crushing needs of different industries.

Scenario-Based Selling Points Extension:
Grain Processing Scenario: For materials like corn, wheat, and cassava dry, the adjustable hammer-screen clearance enables fine crushing of flour (e.g., 0.8mm screen for corn flour) with particle size uniformity >95%, meeting food processing standards.
High-Value Feed Scenario: 0.5mm ultra-fine crushing adapts to aquatic feed (e.g., shrimp and crab starter feed), with material suspension rate ≥90% to improve feed utilization.
Complex Material Scenario: When processing green forage with 25% moisture or extruded feed with 12% oil content, the dual-rotor structure avoids screen clogging and improves production stability by 40%.
Core Technologies and Advantages:
(1) Patented Technology Breakthroughs Solving Industry Challenges
"Double Impact and Circulation Destruction" Patent:
-The dual-rotor structure design achieves dual impact and circulation destruction of materials, significantly improving crushing efficiency and reducing energy consumption.
-Specifically targeting materials with high moisture (e.g., green fodder), high oil content (e.g., oil-containing meal), and high fiber (e.g., straw), it effectively solves the common technical bottleneck of screen clogging (paste screening) in traditional crushing, ensuring smooth material discharge.
"Limit Module Instead of Hammer Sleeve" Patent:
-Reduces hammer replacement time by 2/3, significantly minimizing downtime maintenance costs and improving production continuity.
(2) Precise Structural Design for Diverse Applications
Adjustable Hammer-Screen Clearance:
-The clearance between the hammer and screen can be flexibly adjusted to adapt to different material properties (e.g., hardness, humidity), accurately controlling the crushing particle size distribution and ensuring uniform particle size (coefficient of variation ≤5%).
Multi-Cavity Split Screen Plate:
-Adopts a modular screen plate design, supporting quick replacement of screen plates with different apertures (e.g., 0.5mm, 0.8mm, 1.2mm) to meet diversified production needs, while reducing screen plate wear costs.
(3) Intelligent Fully Automatic Operation
Dynamic Feeding Regulation System:
Equipped with intelligent sensors to automatically adjust the feeding volume, maintaining stable grinder load, avoiding overload or idling, and achieving 10%-15% energy savings.
Multiple Safeguards:
-Optional systems include shaft temperature detection, vibration monitoring, fault alarm, and emergency stop switch, providing real-time early warning of equipment anomalies (e.g., overheated bearings, rotor imbalance) to ensure production safety.
-Supports automatic guidance and current balance adjustment to ensure synchronous operation of dual rotors and reduce mechanical wear.
(4) Exceptional Operational Stability
Aging Treatment Process:
-Key components undergo high-temperature aging treatment to eliminate internal stress, enhance structural rigidity, and extend equipment lifespan by over 20%.
High-Precision Balance Control:
-Rotor dynamic balance detection accuracy ≤0.5g, main bearing vibration speed ≤3.5mm/s. The grinder operates smoothly enough to keep a one-yuan coin standing upright, with noise ≤85dB, complying with environmental standards.
