The Soil Grinder quickly prepares dry soil samples for Atterberg limits, particle-size analysis, and other standard laboratory tests. It is an efficient method for reducing agglomerations of caked soil to individual grains, and much less labor intensive than manual mortar and pestle operation. It preserves true grain size for accurate and repeatable test results.
The hopper has a capacity of about 1 pint (0.6L) and features a manually operated gate to control feed rate to the grinding chamber. Operation is simple, just load the hopper, start the grinder and use the gate to control material feed. A #10 (2.0mm) perforated stainless steel plate is included and retains larger paricles. Most soil types are processed completely in less than 30 seconds per pint.
Rugged stainless steel contact parts reduce sample contamination. The reliable direct-drive motor and grinding unit is mounted on a sturdy painted steel tripod stand. An in-line switch controls motor operation. A stainless steel lid covers the hopper during operation. Operates on 115V/60Hz power supplies.
