Jaw Crushers

If your Jaw Crusher's closed side setting is adjusted once every six months or greater, a traditional shim adjust may be a better investment. If making adjustments to your Jaw Crusher's closed side setting more frequently, less time spent can be spent on adjustment by using push button controls and more time can be allotted for production.

Size reduction control in cone crushers

Size reduction control of cone crushers has received fairly little attention over the past few decades. Consequently, the most common control objective is still to regulate the crusher load (crusher power or crusher main shaft piston pressure) or the closed side setting (the shortest distance between crushing liners), not the actual size …
