Fasteners that hold the liner and seal the shell

Liner bolts carry the liner load and seal the shell against slurry leakage. Cheap bolts stretch, lose preload and cause liner movement. Zhili produces fasteners from qualified high-strength steel, with correct head geometry, thread accuracy and matching sealing washers.

Key features

  • High-strength alloy steel, forged and heat treated
  • Oval-neck, square-head, countersunk and custom head profiles
  • Neck and head geometry matched to the liner seat
  • Threads rolled or cut to tolerance for correct preload
  • Sealing washers, nuts and anti-loosening hardware supplied

Scope of supply

  • Mill liner bolts and shell bolts with sealing washers
  • Crusher liner, jaw plate and cheek plate fasteners
  • Grate and diaphragm fasteners
  • Custom fasteners to drawing, with material certificates

Applications

Customized Solutions

Customized according to your operating conditions

High-wear working conditions

For highly abrasive materials such as limestone and sandstone, we adopt high-chromium cast iron or ceramic composite materials, which extend the service life by 3 to 5 times.

High-impact working conditions

For high-impact materials like construction waste and metal ores, we adopt a reinforced structure with high manganese steel and alloy bars, delivering excellent impact resistance.

High-temperature working conditions

For high-temperature materials including cement clinker and slag, special heat treatment is adopted to retain hardness and wear resistance at elevated temperatures.
