Roll Crushers Engineered for Reliable Operation, Maximum Yield and Easy Maintenance
From Crusher rolls to shafts and bearings, from lubrication systems to easy access housing design, Gundlach roll crushers are engineered with performance and maintainability built in.
Reliable Operation provided by Tough Crusher Shafts & Bearings as well as Main & Secondary Drive Systems.
  Heat treated, forged alloy steel built to tolerate the extreme forces of crushing. Double-row, spherical roller bearings have a L-10 mean operating life of over 100,000 hours.
Main drive options include sheave or flywheel V-belt drives with one motor or two motor configurations available. Secondary drives, for two-stage roll crushers, are powered by either state-of-the-art cog-belt or a heavy-duty roller chain.
Roll Designs Providing Maximum Throughput - the Heart of Roll Crusher Technology
Gundlach roll crushers can demonstrate proven results in wet, dry, hot, cold, sticky, hard and abrasive crushing applications. Roll crushers have been successfully applied to size products ranging from run-of-mine material through fine sizing. There are dozens of roll configurations available to meet your crushing needs.
