Ocher (Geru) Powder Making Machine

What Ocher (Geru) Is Used For

Ocher (geru) is a natural earth pigment historically and currently used in paints, coatings, and traditional ceramic glazing. Ocher's exact shade and tinting strength depend on how finely and evenly it's ground, so a consistent particle size across a batch matters more here than raw throughput speed alone -- the Whizzer Air Classifier's job of returning under-ground particles for a second pass is directly useful for this reason.

Built for Abrasive, Continuous-Duty Grinding

Like the other industrial minerals Thanvi processes, Ocher (Geru) is considerably more abrasive than food or agri-grade materials, so the grinding chamber uses replaceable chilled-iron liner plates and drop-forged alloy steel hammers rather than the FSSAI-compliant Stainless Steel 304 lining used for spice and grain orders. Every configuration also includes a Whizzer Air Classifier, which separates out particles that haven't reached the target fineness and returns them for re-grinding, plus a cyclone dust-bag collection system for the fines. See our materials guide for how this compares across Thanvi's full material range.

Real Capacity by Chamber Size

Thanvi's pulverizer is custom-built per material, capacity, and mesh fineness rather than sold as a fixed named model. Reference points from the actual Ocher (Geru) capacity chart across our eight chamber sizes:

The calculator on our impact pulverizer page matches your required Kg/Hr to the right chamber size automatically once you enter Ocher (Geru) as the material.
