Coconut shells usually need to be crushed before carbonization. This is because coconut shells are usually harder and have larger sizes, and direct carbonization may result in uneven or incomplete carbonization. By crushing the coconut shell, its surface area can be increased and the heat conduction efficiency during the carbonization process can be improved, making the carbonization more uniform and efficient.

There are many ways to break coconut shells, such as physical crushing using crushers, hammers or other mechanical equipment. The particle size of the crushed coconut shell can be adjusted according to specific needs. Generally, the appropriate particle size is selected to facilitate subsequent carbonization treatment.

It should be noted that before carbonizing the coconut shell, the coconut shell should also be dried to remove the moisture. Wet coconut shell will affect the effect and quality of carbonation. Therefore, coconut husks are usually properly dried before crushing
