Laboratory Tower Mill

Fine and regrind test work to −400 mesh

A laboratory tower mill for fine grinding and regrind test work with product fineness down to −400 mesh — where conventional ball milling stalls, tower milling keeps grinding efficiently. Essential for fine-grained ores and regrind circuit design.

Typical applications

Regrind circuit developmentFine-grained ore liberation studiesUltra-fine product preparationEnergy comparison vs ball milling at fine sizes

Why this design

  • Reaches −400 mesh where ball mills become inefficient
  • Regrind is where most concentrators lose recovery — test it properly
  • Scales to our industrial tower mill line (WTM) for full-plant design

How we work with you

  1. Free preliminary assessment — send us your ore type, feed size and duty; we recommend the right configuration at no cost.
  2. Verification — run the machine in your lab, or through our accredited partner laboratory (full test programmes are quoted per sample set).
  3. Quotation in one business day — machines ship in a crate worldwide; installation support is remote or on-site.

Frequently asked questions

Why a tower mill instead of a small ball mill for fine grinding?

At very fine sizes the tower mill’s grinding media action is more energy-efficient and produces fewer extreme fines — your regrind data will actually predict plant behaviour.
