Humbolt Mfg. Company - Soil Grinder: Soil grinders are laboratory tools that are effectively used to reduce agglomerations of caked soil to individual grains with repeatable results. The use of soil grinders saves time and money as compared with the use of mortar and pestle methods.
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. Fits on table top, weighs only 25 lbs.
