Getting activated charcoal wet can cause it to break down more quickly, promote bacterial and fungal growth, reduce its absorption capacity, create a messy residue that stains clothing or surfaces, and make it difficult to ignite or produce smoke. So treat your activated charcoal like the fragile hero that it is.
Dry grinding machine: A dry grinding machine uses no liquid element and relies on particle-on-particle contact to reduce the size of the materials. Wet grinding machine: On the other hand, a wet grinding machine uses a liquid, such as water or solvent, as a lubricant and cooling agent to disperse the particles in a slurry.
Steel slag (SS) is the by-product of steel manufacturing process, with a generation approximate 10–15 % of crude steel capacity [1].

Step 1: Collecting Coconut Shells. The first step in producing activated carbon from coconut shells is to collect the shells. You can either buy them in bulk from a local supplier or collect them yourself if you live in an area with coconut trees. It's important to ensure that the shells are clean and free from any contaminants.
