Simulation for Ball Mill Sizing: The Path to a Successful

1/1/2018· In the presented case study, the ball mill was the critical equipment and oversizing it could have brought the Capex to a level where the project would not have gone through. Grinding Media Sizing Studies: Past, Present, Yamana Chapadas Optimisation of a Copper/Gold Plant

Ball mill upgrade at Collahuasi increases processing

24/2/2020· Ball mill 1012 is located in line 3 of the mines production circuit and had the potential and capacity to process more material if some modifications were made. Collahuasi decided to award the project of repowering this mill to Xinhai, given the previous positive experience and years thepanies had worked together.Within thepany's overall strategy,

Comparing to the widely applied ball milling, the second law efficiency is 16.4 higher for the VRM than the ball mill. Results also showed when the classifier rotor speed increases from 53 to 65 rpm, the particle size of the product decreases from P 90µm = 18.2 to P 90µm = 10.8 , but the power consumption of the VRM unit increases from 19.7 to 22.3 kWh/t of raw materials.

The Cayeli concentratormissioned in 1994, with a design capacity of 600 000 tonnes/year. The grinding circuit was a classical rod mill/ballbination. The rod mill was converted to a primary ball mill in May 1997. The reasons for conversion were to use mill power more efficiently and eliminate feed interruptions during rod charging.
