How to Select the Right Mill for Your Needs
Having a laboratory mill on your premises offers a number of advantages, but you need the right equipment to get the most benefit from your investment.When evaluating lab mills, you should keep in mind the following considerations:
- Batch size
- Starting particle size
- Target particle size
- Process mode (wet, dry, circulation, batch, continuous)
- Scale-up capability
- Ease of operation
- Ease of taking samples
- Ease of making formulation adjustments
- Number of options
- Low maintenance
In many instances, the right choice is an Attritor (sometimes referred to as a stirred ball mill). With an Attritor, the material to be ground is placed in a stationary tank with the grinding media, which are agitated by a shaft with arms rotating at high speed.
Working up to 10 times faster than conventional laboratory ball mills (sometimes referred to as jar mills or pebble mills), the lab Attritor has a compact, vertical profile, requiring minimal space, and can be equipped or retrofitted easily and inexpensively with a variety of components and accessories.
