The simple operation consists of loading the hopper, starting the grinder, and using the gate for manual feed control. Humboldt’s soil grinder prepares samples to a designated particle size with accurate results. The unit includes a No. 10 perforated stainless plate and grinds one-pint samples in just 15 seconds.
The direct drive motor and grinding device is mounted on a sturdy tripod stand, with an in-line switch to control motor operation.
Humboldt soil grinders are available in 120V 60Hz and 220V 50Hz configurations.
