The Molycop range of SAG (semi-autogenous grinding) balls is built for impact and superior wear resistance. Through an innovative manufacturing processes Molycop produces a standard SAG ball and the new generation NG ball. The NG ball delivers reduced:
- weight loss
We use high-carbon alloy steel bars as our raw material and apply special bar heating, forging and heat treatment processes to provide optimum wear and impact resistance. The SAG ball series is used primarily for ore grinding operations in which high impact breakage resistance and high wear resistance are the main ball attributes required.
NG balls for super high-impact performance
Molycop has invested significant R&D effort into developing a SAG ball for greater wear performance and toughness for high-impact SAG mills.
Specialised manufacturing processes and micro-alloy combinations have been developed to produce the Next Generation (NG) SAG ball.
Extensive internal testing and multiple successful field tests have confirmed unprecedented levels of product toughness, which has resulted in high impact resistance and lower spalling rates.
The tougher SAG ball was developed was to meet the needs of modern SAG mills that are being operated more aggressively to maximise throughput. Traditional SAG grinding media, when used in these mills, can experience higher levels of breakage and spalling.
The potential of the new Molycop NG balls to reduce total media consumption may range from 10–15% in lower impact mill environments up to 20–25% in higher impact mill environments, by virtually eliminating the breakage and spalling components of total ball consumption.
