When it comes to the mechanical components of ball mills – which are essential to any hard rock mining operation – the focus is often on the trunnion bearings.
Low Pressure /High Flow oil is circulated from a reservoir to the top of the Trunnion bearing. The low pressure oil coats the journal and other bearings surfaces, helping with oil wedge formation when rotation has been achieved. The high flow circuit will deliver the filtered and cooled oil to the bearing. LIFT & LUBE SYSTEMS
SKF offers solutions for autogenous mills, ball mills, high pressure grinding rolls, rod mills, SAG mils and horizontal grinding mills. The solutions are designed to protect pinions and trunnions and prevent failure in these harsh operating conditions – helping you improve reliability and safety while reducing maintenance and operating costs.
SAG Mill Operation. SAG mills operate differently from ball mills, which rely on the impact of balls to break down the material. SAG mills use a combination of impact and attrition to grind the material. The grinding media in a SAG mill are larger than in a ball mill, and there are fewer of them per ton of ore.
A SAG mill is a large-diameter cylindrical vessel supported at each end by a hollow trunnion. Each trunnion sits on a trunnion bearing. The trunnions are each bolted to the mill shell, while the trunnion bearings are stationary and supported on pedestals.
The net power determined from pilot plant work is increased to cover mechanical losses in the mill trunnion bearings, in the gear and pinion and in the pinionshaft bearings to obtain the power per ton at the …
