Their lower speeds are claimed to reduce fines generation, while lending themselves to high throughput applications. Sizers can either have the rolls rotate towards each other to carry feed between the rolls to be broken, or can be constructed as ‘tertiary sizers’ with the rolls rotating away from each other. With tertiary sizers, feed coal is added between the rolls, and much of the fine material falls through.
