Soil grinders are used to prepare samples for evaluation of grain sizes, Atterberg Limits and other tests. Soil mixers are designed to mechanically mix the sample with an in situ binder. The process breaks up the soil, injects a binder at low pressure and mixes the binder with the soil.

The sample may also be placed in a forced air oven set between 35°C and 55°C. Grinding Recommendations. Soil should be crushed in a soil pulverizer to pass through a 2mm mesh screen. Large clumps of hard soil should be pounded into smaller clumps first. Soil pulverizing time is normally one to four minutes per sample.

The soil chemist or a senior laboratory technician decide which laboratory numbers are to be assigned to the samples. Record sample numbers and the respective lab numbers in the sample reception book and enter them into the computer data base. Sample grinding: Before grinding most samples first have to be dried.
