How to crush calcium carbonate?

To crush calcium carbonate, you can follow these steps:

1. Preparation:

   • Safety first: Make sure to wear safety goggles and a dust mask to avoid inhaling dust particles and protect your eyes.
   • Area setup: Choose a well-ventilated area or use a dust extraction system.

2. Tools and Equipment:

   • Hammer and Mortar: For small quantities, you can use a hammer and a mortar and pestle.
   • Mechanical Grinder: For larger quantities, a mechanical grinder or a ball mill is more suitable.

3. Crushing Process:

   • Small Scale:

     1. Place the calcium carbonate pieces into a sturdy plastic bag.
     2. Crush the contents gently with a hammer until they become coarse powder.
     3. Transfer small quantities to a mortar and pestle to grind it to a finer consistency.

   • Large Scale:

     1. Load your calcium carbonate into the grinding chamber of your mechanical grinder or ball mill.
     2. Operate the equipment as per the manufacturer’s instructions.
     3. Continue grinding until you achieve the desired fineness.

4. Finishing Up:

   • Sieving: For a uniform particle size, sift the ground calcium carbonate through a sieve.
   • Storage: Store the crushed calcium carbonate in a sealed container to prevent moisture absorption.

Always follow the equipment guidelines and handle the material with care to ensure efficient and safe processing.
