All autogenous (AG) and semiautogenous (SAG) mills use steel or rubber grates to hold back the grinding media, whilst allowing the product slurry to flow through and out of the mill. The total open area, size, shape and position of the holes varies considerably from installation to installation (NapierMunn et al., 1996), as given in Table 1.
SAG Mill vs Ball Mill. ... and a grate design to facilitate maximizing both pebblecrushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of :1 and :1. This ratio range is stated without reference to face angle; in general terms, and at equivalent spacingto ...

That is why we utilize the latest design and simulation software to ensure your Mill Liner System will provide optimal grinding performance at the lowest operational cost. ComputerAided Design (CAD) 3D DEM Simulation. 3D Laser Scanning.
Rubber liners absorb the impact of the larger grinding media and thus protecting the mill structure and prolonging it's life. Weight: Rubber weighs about 15% of an equivalent volume of steel. This means that a rubber liner system reduces the load on the mill structure and also reduces the basic power draw.
Suitable for AG, SAG, ball, pebble, rod batch mills, FGD, SMD and continuous mills. Metso rubber mill liners are tailormade and developed in close collaboration with our customers. Being the pioneer, Metso rubber mill linings are designed and produced based on the world's largest bank of knowhow and experience.
