Due to the criticality of the pinions on a ball mill, most companies will have a spare available. And this is where the expertise of CBC Australia is so important to hard rock mining operators around Australia. The CBC engineering team habitually custom-build pinion assemblies for customers in this segment.
These companies often rely on our technical support team to assist them with bearing installation on the pinion assemblies, says OKeefe. We recently built a pinion from scratch for a customer in the gold mining industry, who are extremely happy with the result. Its common for us to assist our customers with pinion assemblies in hard rock mining applications. Whether that is in replacing and installing components, such as the pinion bearings, or setting up a spare pinion that is ready to go in the case of a breakdown.

Availability of stock is critical. The stock we have on the shelf from Schaeffler is world-leading and our relationship with Schaeffler ensures we have this available to customers, says OKeefe. The German-engineered FAG spherical roller bearing is very high quality and typically seen as the best-suited to this application.
The FAG spherical roller bearings are part of Schaefflers X-life range. According to Schaeffler expert Milos Grujic Manager of Heavy Industries at Schaefflers exclusive ASB Grinding Mills Competence Centre these spherical roller bearings were the first of their kind and are the best in class.
The FAG spherical roller bearing has the highest capacity of any spherical bearing that is manufactured. Considering that this spherical roller bearing E design was invented by FAG many years ago, suffice to say, Schaeffler is the world leader in the ongoing progression and design of these bearings, confirms Milos. These X-life bearings provide up to two times the service life of the old design in this class.
Milos further explains that the Schaeffler X-life FAG spherical roller bearing is the preferred choice for pinions because it is a low friction, robust bearing with a high axial load-carrying capacity.
As the pinion gears are driving the girth gear that turns the mill, they need to have a high capacity in order for the gear to have a long life in these conditions, Milos says. These girth gears are extremely valuable assets, some of them costing one million dollars or more. So, I cannot stress enough the importance of having a high capacity bearing that can take the high axial loads typical to this application. This will ensure a greater life of the ball mill machinery.
MACSALAB Rod Ball Mill Vessels are available in Grade 304 and 316 Stainless Steel, Rubber - lined Mild Steel as well as Ceramic Alumina.
Grinding Spheres balls are available in Steel, Zirconia and Alumina. Quantity and sizes to clientrsquos specifications.
MACSALAB Drive Rolls for Rod Ball Mills are Rubber coated and manufactured in Double and Triple Roll models. The Rolls are 120 mm diameter x 1200 mm long and powered by a 0.37 KW 220 Volt Motor with a variable speed controller.
The BallRod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.
A horizontal rotating cylinder vessel is partially filled with ballsrods grinding media, usually stone or metal, which grinds material to the necessary fineness by friction and impact with the tumbling ballsrods. A rotating drum throws material and ballsrods in a counteracting motion which causes impact breakage of larger particles and compressive grinding of finer particles. Attrition in the charge causes grinding of finer particles.
These units are primarily used in the gold, copper and platinum industries with applications also in the lead, zinc, silver, alumina and nickel industries.

Try to limit the size of the batch to 25 of the total vessel volume which is sufficient to fill the voids and slightly cover the grinding Media. Any larger batches cause the balls to spread out throughout the mass of solids so they cannot make effective contact with each other, because of the layers of material between them. This greatly reduces the grinding efficiency of the mill and in some cases makes it impossible to attain the desired results.
