25 Module Casting Steel Custom Made Girth Gears For Ball Mill of Cement Plants
1) Description of Girth Gear
a) Girth gears are manufactured from alloy steel castings with a capacity of up to 150 tons or Ø12.5m per gear set
b) We manufacture pinions and gearbox internals from through-hardened or case-hardened alloy steel forgings
c) Gear tooth and root areas are subjected to grinding if necessary, ensuring a high degree of accuracy in gear manufacture
d) An in-board testing head enables the production of gear quality inspection graphs to verify tooth profile, lead, pitch,
run out and span values and deviations.
