Mechanical impact in disk mill for producing controlled rice husk particle size by changing impactor shapes and disk rotation speeds
The purpose of this study was to evaluate regulation of mechanical impact (i.e. impactor sizes and shapes) on triangle, cylinder, and cube as well as disk rotation speed (from 600 to 1500 rpm) in disk mill for controlling size-reduction process. As a model of size-reduced material, rice husk was s...

The purpose of this study was to evaluate regulation of mechanical impact (i.e. impactor sizes and shapes) on triangle,
cylinder, and cube as well as disk rotation speed (from 600 to 1500 rpm) in disk mill for controlling size-reduction
process. As a model of size-reduced material, rice husk was selected. The study was done by evaluating the final milling
product size, which was completed by the measurement of energy impact during the milling process. Experimental
results showed that the product size was controllable in the range of between 50 and 1000 μm. The impactor sizes and
shapes influenced the contact diameter and area of impactor for making more materials being collided, whereas disk
rotation speed led to giving more collision number (between rice husk and impactor) and increasing impact from the
collision (due to less time contact during collision). This study provides an important information, which can be further
generalized in the use of milling process as a tool for materials size-reduction and mechanochemical process. |
