Abstract
Workpieces are ground by rolling them around with grinding bodies and microbodies (7) in a vibratory scouring container (1) while a processing liquid is fed into, and runs out again from, the scouring container. The microbodies run out of the container with the processing liquid, are washed and screened in a device (17) to separate those having dimensions less than a predetermined size. The residual larger microbodies are collected in a storage container (8'). The container (8') is subsequently mounted on a post (10) in place of a similar container (8) and the microbodies are returned in controlled amounts into the scouring container by flushing out through a discharge opening (11) with water.
