Abstract

A grinder for wood pieces, such as sticks, which is provided with two press boxes arranged opposite a grinding stone and also provided with two grinding pistons operated by hydraulic presses is provided in accordance with the present invention with an intermediary switch arranged between two limit switches which controls the operation of one of the two grinding pistons. This intermediary switch causes a reversal of the other grinding piston by energizing an electromagnet which operates a hydraulic valve.
