Apparatus for treating granular flowable material in another, with means for imparting vertical movement to the usable oscillatory particularly as washer tub.

摘要

Material is treated in a container to which oscillating motion is imparted by the movable core of an electromagnet located below the container. - The container is resiliently suspended, pref. by straps inclined upwardly from a base, so that vertical oscillation is given a rotary component as well. - Specifically, the appts. is for washing clothes, or for screening, flotation, grading, chemical treatment and cooking processes.
