Why should I use a Mineral Sizers over a Jaw Crusher, Gyratory Crusher or Impactor?
A Mineral Sizer offers a more effective means for crushing clay-ridden sticky material, eliminating the need for recirculation of oversized material as produced by Jaws, Gyratories or Impactors. Mineral Sizers have a lower capital cost than other primary crushers as well as a lower infrastructure/structural cost.  Do I have to use the breaker bar in my Mineral Sizer?
No, but the benefits of using the breaker bar are twofold. The breaker bar eliminates slabby material from escaping the machine, and it can deliver a higher ratio of reduction. 
Do I have to remove the shaft from the Mineral Sizer to replace the crushing hammers?
No, the Mineral Sizers roll shafts are designed so that the wear segments and wear hammers can be easily removed and replaced without having to remove the roll shaft.
