Our Team

Production Manager, Cement Plant
Since switching to Allstar high-chrome cast grinding balls, the breakage rate has stayed below 0.1%, greatly reducing mill downtime. Wear consumption dropped to only 15 g/t of cement. For our annual production of 2 million tons of cement, media consumption decreased from about 80 tons to 30 tons per year. This alone saves our plant over USD 40,000 annually, while mill productivity has also improved. The economic benefits are very clear.

Michael Turner
Mill Superintendent, Copper Mine
We tested several grinding media suppliers before choosing Allstar. After using their grinding balls, our media consumption dropped to around 0.66 kg per ton of ore, compared with about 1.4–1.7 kg/t previously. The difference is very noticeable in daily operations — fewer ball additions and more stable mill performance. Based on our annual throughput of about 3.6 million tons of ore, the savings on grinding media alone are over USD 700,000 per year.

Carlos Ramirez
Operations Supervisor, Mining Company
So far the rods are performing much better than those from our previous supplier. They don’t break as often, which means less downtime for replacing rods in the mill.
