For example, coarse crushers have size reduction ratios of below 8:1, whereas fine grinders may have ratios as high as 100:1. However, large reduction ratios, such as those obtained when dividing relatively large solid lumps into ultrafine powders, are normally attained by several stages using diverse crushing and grinding machines.

Tertiary crushers are commonly used in the aggregates industry for final particle shaping to increase cubicity, and to produce a product size beyond what is capable from a primary or secondary. This stage of crushing is typically accomplished using a vertical shaft impactor or coarse, medium-fine, or fine grinding cage mill.

Cone crushers also have a high crushing ratio, and they're able to quickly process raw material to a more uniformly fine size than first stage crushers. As the mantle rotates at high speed, it quickly transforms raw material into smaller particles, which also helps to reduce operational costs. Easy to Maintain
