Motor Rotor Crusher

Motor Rotor Crusher Main Structure Diagram

Motor rotors consist of copper windings tightly embedded in iron cores (silicon steel laminations). Currently, scrap motor rotors are priced around USD 700/ton, while copper trades at over USD 4,000/ton. Each ton of processed rotors yields approximately 0.25 tons of pure copper, offering exceptional profit potential. Haoxing Machinery's Motor Rotor Crusher is a specialized hammer mill and multi-stage separation line engineered for the efficient crushing and copper-iron separation of scrap motor rotors and stator windings. Using purely physical processing methods, the system completely liberates and separates copper from iron, producing high-purity copper granules and clean silicon steel scrap.

Applications

• Scrap motor dismantling and recycling enterprises.

• Copper and iron scrap sorting and processing centers.

• Feedstock pre-processing for secondary copper smelters.

• Motor repair shop scrap rotor processing.

• E-waste resource recovery bases.

Composition of motor rotor crusher processing equipment

Working Principle:
The Motor Rotor Crusher operates on the hammer impact principle. A high-speed motor drives the main shaft and rotor assembly equipped with high-chromium alloy hammers. Scrap rotors are fed into the crushing chamber where hammers deliver powerful impacts. Material is repeatedly struck and ground between the hammers and impact liners until reduced to small granules, which then pass through a bottom screen. The crushed material then enters a multi-stage sorting system for complete copper-iron separation.

Process Flow:
The complete line uses purely physical, environmentally friendly processing:

1. Primary Crushing: Scrap rotors are fed into the primary crusher for coarse size reduction, loosening the copper windings from the iron core.

2. Secondary Crushing: Material enters a secondary crusher for further refinement, fully liberating copper from iron.

3. Magnetic Separation: The crushed mixture passes through a high-intensity magnetic drum separator, which removes the iron (silicon steel) fraction.

4. Fine Crushing: The remaining copper-rich mixture is sent to a fine crusher for further particle size reduction.

5. Air Classification: Finally, an air classifier separates pure copper granules from any remaining lightweight impurities.

Core Line Components:

• Primary Crusher

• Secondary Crusher

• Infeed Conveyor

• Belt Conveyors (Multiple)

• High-Intensity Magnetic Drum Separator

• Air Classifier

• Pulse Dust Collector

• Centralized PLC Control Cabinet

Motor Rotor Crusher Crushing and Sorting Process

1. Large Feed Opening for Bulky Rotors
   Wide feed opening and deep crushing chamber accept whole motor rotors without pre-cutting, with minimal dust generation.

2. Adjustable Hammer Gap for Precise Sizing
   Gap between hammers can be easily adjusted to control output particle size and achieve optimal granule shape.

3. Compact, Rigid Structure with High Rotational Inertia
   Compact design with high structural rigidity. The rotor has significant rotational inertia for stable, efficient crushing.

4. High-Chromium Alloy Hammers, Impact & Wear Resistant
   Hammers are made from high-chromium alloy, offering excellent impact strength and wear resistance for long service life.

5. Keyless Connection, Easy Maintenance
   Keyless connection design allows quick and convenient maintenance, reducing downtime.

6. Comprehensive Crushing, High Overall Efficiency
   Complete crushing functionality with high productivity and minimal component wear. Thorough copper-iron separation yields high-purity copper, maximizing resale value.
