Optimal design of jet mill bit for jet comminuting ...

A new type of bit called jet mill bit (JMB) has been designed and manufactured in this research. Its sketch and flow diagram are shown in Fig. 1.In principle the JMB is different from conventional PDC bit in that it is constructed with jet comminution device that use high velocity gas jet to impart energy to cuttings to project against comminution targets for cuttings size …
