Flextooth Crushers by Jeffrey Rader Brand

Flextooth® crushers are designed for the reduction of ROM coal, for preparation plant feed, rail shipments and feed for fine coal grinding equipment.

Features

Flextooth® Crushers combine the benefits of the compression crushing concept of roll crushers with the high capacity of impact crushers.

Advantages & Benefits:

  • Maximum reduction ratio with minimum fines
  • Improved protection against damage from tramp metal and other uncrushables
  • Can accept large lumps of ROM or frozen coal
  • Individual screen sections can be replaced, helping reduce maintenance costs
  • Rotors can be set up with three, four or six rows of hammers for premium efficiency when crushing to a smaller product size
