Abstract:

The invention is a detachable “blade foil” system for comminuting machines which employ a rotating turbine. The turbine blades are each endowed with a detachable leading edge which is shaped in an air foil configuration. These “blade foils” are penetrated by a vent chamber having an inlet port and an outlet port. The vent chambers aid in drying input material that is processed by a comminuting machine and also aid in reducing sound from the turbine. The configuration of the inventive blade foils also vary to aid in material drying. The configuration of the blade foils also define the level of particle size attributed to the processed output material. Hence by selecting particular blade foil configurations the operator can achieve different levels of material drying and differing output particle sizings.
