sawdust-like consistency with particle sizes ranging from ~0.1-4 mm before being pelletized. Laboratory testing using a bench-scale ball and race mill was performed on wood pellets to predict particle size reduction to be expected from the coal pulverizer. Results indicated that the pulverizer will break the pellets down, but.
When a pulverizer manufacturer rates capacity at 100,000 pph, there are strings attached. Associated with that rating are limits on coal grindability, moisture, feed size and output fineness, along with some reasonable PA/fuel ratio. Each of the parameters will affect the effective size of the machine. For example, consider a.
