Hi- Chrome Grinding Media Balls:
Growing from strength to strength over 40 years, Atul Engineering Udyog is inspired by a strong legacy and motivated by the vision to remain world-class through a focus on high quality products. Always alert and sensitive about the importance of quality, AEU seeks to present value-added propositions to all customers. It has geared itself by facilitating advanced R&D activities in every area of application to develop best engineered products. Modern plants crush various types of materials leading to a variety of working conditions. These varying conditions require completely different grinding properties from the grinding agent. Our team of experts have done extensive field research and found that the properties required in the grinding media vary from low abrasion, high impact conditions to highly abrasive lower impact conditions. Accordingly, our R&D team has formulated three different grades to cater to these separate requirements as follows :-
Specifications
- Balls (mm) – 125, 100, 90, 80, 75, 70, 65, 60, 50, 40, 30, 25, 20, 17, 13
- Cylpebs (mm) – 25×25, 22×22, 19×19, 16×16
