Solution

The use of girth gears is commonly found in the mining, cement, mineral, and other industries. Frequent use of grease with an asphaltic base often results in a lot of dirt, causing the grease to dry out and accumulate. This can lead to damage to the girth gear in rotary kiln equipment.

Did you know that rotary kilns and ball mills play a 25% – 50% role in the production process?

Given the importance of rotary kilns, dryers, SAG mills, and ball mills in a process, these tools are always maintained for optimal performance. This includes their main drive component, the girth gear. This gear is the primary driver for rotary kilns and ball mills, so the choice of lubricant for the girth gear will affect its performance. Conversely, choosing the wrong lubricant can result in damage to the girth gear.

What is the cost of replacing a girth gear on a rotary kiln or ball mill? For major damage, the cost is around Rp 300 million, and for minor damage, it is around Rp 70 million. By using the right girth gear grease, you can save all these costs.
