High Productivity:

Simultaneous processing of 4 samples (ideal for comparative studies or parallel experiments).

Example: Test 4 different catalysts in identical conditions.

Versatility:

Use different jar materials (e.g., stainless steel, ZrO₂, nylon) for each station.

Run wet/dry grinding or mix protocols in parallel.

Energy Savings:

Shared motor reduces per-sample energy cost vs. single-jar mills.
