How to crush material from 12mm to 6mm?

To crush material from 12mm to 6mm, you can follow these steps:

1. Select the Appropriate Equipment:

   • Jaw Crusher: Ideal for initial coarse crushing. It can handle larger pieces of material and reduce them to around 10-15mm.
   • Roll Crusher: Good for secondary crushing and capable of handling smaller sizes.
   • Hammer Mill or Impact Crusher: Both can further reduce the size of materials to finer particles.

2. Prepare the Material:

   • Ensure the material is clean and free of debris that could damage the machinery.
   • Sort the material to remove any oversized pieces that might not fit in the crusher.

3. Setup the Crusher:

   • Adjust the gap settings on your secondary crusher (like the roll crusher or impact crusher) to achieve the desired output size of 6mm.
   • Check the manufacturer's guidelines for gap settings and throughput rates.

4. Process the Material:

   • Feed the material into the jaw crusher for initial size reduction (if starting with larger pieces).
   • Once reduced to around 10-15mm, feed the output into a roll crusher or hammer mill to achieve the final reduction to 6mm.

5. Quality Control:

   • Run sample batches and measure the output size to ensure it meets your 6mm requirement.
   • Adjust the crusher's settings as necessary to achieve uniform particle size.

6. Safety Precautions:

   • Wear appropriate PPE (Personal Protective Equipment) such as gloves, goggles, and ear protection.
   • Ensure all guards and safety devices on the machinery are in place and functioning.

By carefully selecting and adjusting your equipment, you can effectively crush material from 12mm to 6mm.
