VC Clutches for Grinding Mills Airflex® is the logical choice for new grinding mill designs or for modernizing existing equipment. Airflex ’s air-actuated, drumtype clutches are the logical choice for master clutch service on pebble, rod, ball, semiautogenous and autogenous mills used in the grinding of various materials. ® When modernizing existing mills or other equipment, very little engineering is required for installing Airflex clutches in place of existing direct drive systems. ® The uncomplicated design and the ability to modulate power transmission insures reliable service and...

Airflex provides a total solution for grinding mill applications. This includes: ® Air actuation and the absence of linkages, splines or complex electrical circuitry, needed with other types of clutches, eliminates many mechanical failures and minimizes costly downtime. Air is only used during engagement of an Airflex Clutch®. This is because the clutches are designed as closed loop systems. Neither the driving nor the driven shafts need to be removed to service the clutch. The clutch element and drum can be dropped out between the shafts by unbolting them from the mounting components....
