How To Minimize Crusher Fines In A Coal Appli ion ...

During the crushing phase, there are steps that can be taken to minimize fines generation and increase the product yield. Lower roll speeds. Whenever coal is handled, whether by man or machine, it tends to degrade. The minute particles that form coal dust are the results of coal degradation.

Roll Crusher - an overview | ScienceDirect Topics

Their lower speeds are claimed to reduce fines generation, while lending themselves to high throughput appli ions. 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.
