Designed to accept medium large feed and produce a cubical product with a minimum amount of fines.

A Quadroll is essentially two Double Roll Crushers in one unit. The primary stage accepts feed lumps and crushes the material to an acceptable size for secondary stage crushing. The secondary stage crushes to the desired product with minimum fines production.

• Super Quadroll
  Intended for handling high capacities of R.O.M. coal containing moderate percentages of medium hard refuse. Performs a high ratio of reduction. High capacity eliminates necessity of prescalping thus saving space and headroom.
• Medium Duty
  Intended for reduction of medium size feeds to a marketable size in
  one pass. Used primarily for medium or hard coal, salt, and other
  materials of similar characteristics. Not to be used for crushing rock,
  refuse or similar hard feeds.
• Standard Duty
  Intended for reduction of medium size feeds to a marketable size in
  one pass. Used primarily for soft to medium salt, and other materials
  of similar characteristics. Not to be used for crushing rock, refuse or
  similar hard feeds.

• Abrasive Material
  This unit was designed for hot abrasive feeds, reducing sintered iron
  ore, coke, and other abrasive materials. This crusher is essentially the
  same as the Standard Duty model however, a number of features have
  been included to limit wear caused by abrasion.
