The stainless steel hammermill-style soil grinder can process a soil sample in just a few seconds. The 1.5-horsepower electric motor drives the knife assembly at 1725 rpm, quickly crushing and homogenizing the soil sample. The hardened steel knives will process several thousand soil samples before the knives need replacement. The soil grinding chamber can grind and homogenize small or large soil samples, holding up to 5-7 lb soil in the grinding chamber.
The power sieve, available with 1- or 2-mm screen, will catch soil and remove coarse fragments and crop residue from the processed soil sample. The power sieve is bolted directly below the soil grinder, automatically removing stones and debris as soil exits the soil grinder. The power sieve is recommended for high-throughput operations. A catch bucket or conveyor system should be installed underneath the power sieve to discard debris.
The soil grinder-power sieve combination is only sold with the 230 VAC wired configuration. Both soil grinder and power sieve are wired to one 230 VAC electrical plugin with manual motor starter switch controlling both motors (total 9.6 A, 60 Hz, 1-phase).
