CementKiln Drive & Mechanical
Kiln pinion casting (small gear driving girth gear)
Pinion is the faster, smaller gear – higher tooth contact stress. Some large kilns use FORGED pinions for higher toughness. Smaller kilns: cast pinion acceptable. Hardness: pinion typically harder than girth gear (HB 220–280).
