Excavator

The most important component in cement production is limestone. Limestone is extracted through blasting in opencast mines before being crushed. The crushed limestone is then transported via conveyor belts to a blending bed for temporary storage.

one of the most important devices in the mines are excavators. the parts which are involved with abrasion are: 

• Excavator shovel: Wear is predominantly caused by abrasion and can be accompanied with a great deal of impact. Most buckets re fabricated from combination of carbon steel & manganese steel & may be lined with a abrasion resistant liners.
  
• Bucket teeth: Bucket teeth come to use in the excavating of ore, stones or other materials. Wear is predominantly caused by  brasion and can be accompanied with a great deal of impact.
  
• Idler: Undercarriage components typically wear by metal to metal, abrasion and slight impact.
  
• Track roller: Undercarriage components typically wear by metal to metal, abrasion and impact.
  
• Drive sprocket: Undercarriage components typically wear by metal to metal, abrasion and impact. 
  
• Tooth Adaptor: In addition to abrasive wear, cracks may occur due to overload.
