Grinding Media plays a critical role in the ball mill operations as it is the only mill internal contributing to energy / specific power consumption. AIA Engineering Ltd. / Vega Industries is globally the largest producer of High Chromium Grinding media. As a pioneer in this field AIA/ Vega adds value to this product with its decades of experience and expertise. We have dedicated high pressure moulding lines for higher and lower size Grinding Media, resulting in required soundness of the products.
Big balls, ranging from 100 mm to 60 mm, are essentially used in the first chamber of the mills for crushing the feed material. These balls impart potential energy for crushing and thus required to possess a combination of wear and impact resistance

Grinding by attrition is accomplished by numerous small balls of varying sizes in second chamber. These balls contribute significantly to the grinding efficiency of the mills. Residue/blaine control of the final product depends much on the quality of the balls used.
Mill internal design plays an important role in production efficiency. They not only protect the mill shell but also transfer the energy from the mill shell to the rotating charge of grinding media. The internal castings contribute upto 5% of the ball mill operating cost while the remaining 95% is from energy.
AIA Engineering Ltd. /Vega Industries products follow the golden triangle philosophy of Design, Metallurgy and Application for tailor-made solutions based on multiple parameters such as feed characteristics, product specification and operating conditions resulting in –
Optimum grinding requires effective crushing. First chamber liners are designed to achieve size reduction at optimal power.
AIA / Vega Liners provide –
Attrition is the most important part of the grinding process. AIA Engineering Ltd. /Vega Industries offer a variety of classifying liners to choose from for specific applications.
Diaphragm is a partition wall restricting the metallic content within the chamber and controlling the movement of feed material through the mill.
Level Control Diaphragm
Outlet Diaphragm
AIA Engineering Ltd. /Vega Industries have been at the forefront of developing solutions for vertical mill castings for all applications, types and makes, constantly upgrading on its own products.
The latest innovation V cast addresses the industry demand for a suitable solution for highly abrasive applications. This is a result of focused field and R & D efforts, resulting in following demonstrated benefits
The purpose of a mill study is to collect information about the mill running conditions. These data help us in redesigning the mill internals and grinding media pattern (Ball Mills).
Analysis of audit result to identify bottlenecks and areas of improvement. Implementation of corrective action and monitoring for improvement.
The case study demonstrates Vega Industries’ expertise in providing productive and sustainable solutions for Mill product performance and quality with the help of Vcast Rollers.
