Roll Crushers

Goods Description:The First and Only Roll Crushers Able to Size Coal, Salts, Potash, Lime and Soft Minerals in 3 Dimensions Gundlach roll crushers are available in four model series with single-stage and two-stage designs. Rolls range from 300 mm to 900 mm, with roll lengths 500 mm to 3000 mm, and feeds up to 1200 mm and product sizes to 6 mm.

These roll crushers are available with Gundlach's breakthrough 3-D crushing technology that includes intermeshing continuous tooth roll design and positive roll timing that delivers the industry's best dimensional product control, fewer fines and elimination of over-size material. Gundlach's roll crushers deliver higher quality cubical product, minimal fines and consistently repeatable performance for sizing coal, coke, glass, fertilizer, potash, salts, lime, limestone, soft ores, friable materials and industrial minerals.

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.
