By inserting shims above the toggle block, the crushing stroke can be adjusted. Insertion of shims behind the toggle block adjusts the size of the discharge opening. Parallel alignment is assured and unnecessary strain in the crushing machine is avoided. The pitman in any jaw crusher is essentially a tension member.
The increased number of impacts in the VIBRADRUM® Grinding Mill results in a faster, more efficient grinding action. As the grinding mill vibrates, media particle migration is experienced in both axial and transverse directions.
