V-cast: A tailor-made solution for grinding Green Cement

Product – V-Cast Wear Segments for VRM

Location – Middle-East

Client – A Cement plant in the region

Result – 3.5 times improvement in Life of Wear Segments as compared to High Chrome

Vega developed V-cast, a new solution for abrasive grinding conditions. The product is specially designed for providing longer durability based on feed material characteristics of Limestone raw material, Coal, Clinker and Slag.

Problem:

The customer was facing the following problems in their Raw mill Atox 40 due to highly abrasive feed composition:

• Severe wear on the grinding elements
• Sand blasting effect on mill internal body Liner and Classifier
• Excessive dust load and unstable operation

Solution

Vega identified the problem areas by conducting a mill audit and recommended corrective measures in their existing setup along with supply of V-cast roller tires.

Following was the impact observed: –

Set Details Conventional Grinding elements V-cast
Running Hours 5100 5100
Wear Depth(mm) 60.7 18
Wear Speed(mm /1000 hrs) 11.90 3.52

Post implementation of suggestions the mill operations have observed lower dust load resulting in steady operating conditions. Further, installation of V-cast roller segments resulted in substantial improvement in wear life by three-fold.
