In the last article, we introduced the summer maintenance for mining crushing plant. Today, we will introduce the maintenance for crushing & screening machine in details.
Summer Maintenance Tips for Jaw Crushers
Jaw crushers are commonly used as primary crushing equipment in mining and quarry applications. During summer operation, operators should focus on:
Bearing Inspection
Jaw crusher bearings experience heavy loads and impact forces.
Check regularly:
* Bearing temperature
* Lubrication condition
* Abnormal noise or vibration
Overheated bearings may indicate insufficient lubrication or excessive load.
Jaw Plate Wear Monitoring
Worn jaw plates can reduce crushing efficiency and increase energy consumption.
Operators should:
* Check jaw plate thickness regularly
* Adjust discharge opening when necessary
* Replace worn plates in time
Summer Maintenance Tips for Impact Crushers
Impact crushers operate at high speed and are widely used for secondary and tertiary crushing. Key maintenance points include:
Check Rotor Balance
The rotor is one of the most important components of an impact crusher.
Inspect:
* Rotor condition
* Blow bar wear
* Fastening bolts
Uneven wear may cause:
* Increased vibration
* Bearing damage
* Reduced crushing performance
Prevent Material Buildup
Wet or sticky materials may accumulate inside the crushing chamber.
Protect Cone Crushers from High Temperature Problems
Cone crushers are widely used for hard rock crushing and high-capacity production. The lubrication system is the most important area during summer.
Operators should monitor:
* Oil temperature
* Oil pressure
* Cooling system performance
* Hydraulic system condition
High oil temperature may cause:
* Increased wear of internal components
* Damage to copper bushings
* Unexpected production stoppage
Regular maintenance of oil coolers and filters is essential.
Maintain VSI Sand Making Machines for Stable Sand Production
VSI sand making machine is often used for producing manufactured sand. Because they operate at high speed, summer inspections should focus on:
* Main shaft bearings
* Rotor wear parts
* Wear-resistant components
High moisture or excessive clay content in feed materials may reduce sand production efficiency.
To improve performance:
* Control feed quality
* Remove excessive fine soil before crushing
* Replace worn wear parts promptly
Keep Sand Washing Machines Operating Smoothly
Sand washing machines work in wet environments, making sealing and lubrication especially important.
Check:
* Bearing seals
* Spiral blade wear
* Drive system condition
Common summer problems include:
* Water entering bearings
* Increased wear caused by mud
* Reduced sand cleaning efficiency
Proper maintenance helps improve finished sand quality and reduce material loss.
Maintain Vibrating Feeders and Vibrating Screens
Vibrating equipment is essential for material feeding and classification.
Vibrating Feeder Maintenance
Check:
* Exciter temperature
* Spring condition
* Bolt tightness
* Vibration stability
Loose bolts or damaged springs can reduce feeding efficiency.
Vibrating Screen Maintenance
A vibrating screen directly affects final product quality and production capacity.
* Select suitable screen mesh
* Clean blocked openings regularly
* Check vibration amplitude
* Inspect screen frame and bolts
For wet materials, anti-blinding screen panels may help improve screening performance.
The most important principles for summer crushing plant management are control temperature, maintain lubrication, ensure stable feeding, prevent blockage, and inspect equipment regularly. With a well-planned maintenance strategy, mining companies can reduce unexpected downtime, improve production efficiency, and extend the service life of crushing and screening equipment throughout the summer season.
