Chain Crusher

Chain Crusher Structure and Working Principle

Rotor System:

• Dual-rotor horizontal design (mainstream model), with each rotor shaft independently equipped with a motor, achieving a chain circumferential speed of 28–78 m/s.
• The rotor main shaft is fitted with a chain seat and ring chain, with the ring chain ends featuring wear-resistant steel forged chain heads to extend service life.

Machine Body and Protection:

• The machine body is lined with rubber plates or polypropylene plates to reduce wall adhesion and corrosion. Quick-opening maintenance doors are installed on both sides for easy cleaning and maintenance.
• The base integrates vibration dampers to reduce operational vibration and noise.

Drive system: Dual motor belt drive ensures high torque output.

Working principle

Material enters the chain crusher through the feed port and is directed into the dual rotor zone. The high-speed rotating chains subject the material to multiple impacts:

• Primary crushing: One side of the rotor chains strikes the material, propelling it toward the other rotor;
• Secondary crushing: The opposing rotor chain strikes the material a second time, achieving particle refinement;
• Particle size control: The output fineness is controlled by adjusting the number of chains (can crush to below 1 mm when fully loaded).

Core Advantages of Chain Crusher

High Adaptability:

• Can process sticky materials with a moisture content of 50% (such as livestock manure and sludge) without clogging.
• Corrosion-resistant design (plastic lining + alloy chain head) extends equipment service life.

Energy Efficiency and Maintenance:

• Dual motor independent drive saves 15%–20% energy compared to traditional single-rotor designs.
• Quick-opening machine door facilitates rapid maintenance, minimizing downtime.

Flexible particle size control: Adjusting the number of chains allows adaptation to coarse crushing (≤3mm) or fine crushing (≤1mm) requirements.

Technical Improvements

Vertical chain hammer composite design: Combines chain pre-crushing with hammer plate fine crushing, achieving a particle size of 50 mesh (0.3mm), suitable for ultra-fine fertilizer or mineral processing.
