Crusher Chain Lubrication System

Core Working Principle

1. Conveying and Spraying

    

   Electric pump serves as power unit to fluidize dry lubricant and deliver fixed volume. Lubricant is directionally sprayed onto chain hinge joints through properly arranged nozzles.
    
2. Precise Control

    

   The system is managed by PLC or dedicated controller.
    

• Timing control: Spraying operates at preset intervals
• Metering control: Lubricant dosage is controlled at milligram level per spray
• Optional conditional triggering: Intelligent on-demand lubrication supported via chain speed, temperature sensors or equipment operating signals

Main System Components

1. Main Controller

    

   Core unit to set lubrication cycle, spraying duration and interval parameters. It monitors operational status and triggers alarms for low material level and insufficient air pressure.
    
2. Lubricant Tank

    

   Stores lubricant materials.
    
3. Lubricant Delivery Unit

    

   Metering device accurately regulates lubricant output per injection.
    
4. Piping and Nozzles

    

   Pressure-resistant and wear-resistant pipelines transport lubricant to dedicated nozzles mounted beside chains. Nozzles ensure full coverage of gaps between pin shafts and sleeves.
    

Working Process

1. The controller activates lubrication cycle according to preset programs or startup signals.
2. The electric pump starts running.
3. The metering device discharges fixed quantity of lubricant.
4. Lubricant is sprayed at high speed toward chain hinge points.
5. Under impact force and friction heat, lubricant penetrates tiny clearances and forms a thin, uniform protective film.
6. The pump stops once spraying finishes. The system stands by for the next cycle.

Core Advantages

1. Complete Sludge Elimination

    

   Lubricant hardly absorbs dust, avoiding hard sludge accumulation. It effectively lowers risks of chain jamming, tooth skipping, abnormal wear and fracture.
    
2. Reduced Wear and Extended Service Life

    

   Accurate targeted lubrication isolates metal contact, greatly prolonging chain service lifespan.
    
3. Lower Lubricant Consumption

    

   Milligram-level precise dosage cuts unnecessary waste and pollution, reducing overall operational cost.
    
4. Less Frequent Maintenance and Lower Cost

    

   Manual greasing work is minimized. Downtime and replacement cost caused by sludge blockage and severe wear are reduced. Clean working conditions also save cleaning expenses.
    
5. Enhanced Operational Stability

    

   Unplanned shutdowns resulting from chain failures are reduced to guarantee continuous production.
    
6. Eco-friendly Performance

    

   No oil dripping or contamination keeps equipment and workshops tidy. Oil-containing waste discharge is decreased, and most dry lubricants feature superior environmental performance.
    
7. Strong Working Condition Adaptability

    

   Applicable to harsh environments where traditional lubrication performs poorly, including high dust, high temperature, humidity, water splash, heavy load, low and high speed working scenarios in mining, cement and metallurgy industries.
    

Main Application Scenarios

• Transmission chains of jaw, cone, impact and hammer crushers in mining industry
• Chains for raw material and clinker crushing and conveying in cement plants
• Chains of crushing and sorting conveying lines in waste treatment stations
• Chains used in raw material processing, sintering and pelletizing procedures in metallurgical plants
• All industrial equipment with reliable chain transmission demands under heavy dust pollution
