The single roll crusher reduces large size particles in the feed to a medium size while producing a considerably lower percentage of fines than other crushers.
Frame of Single Roll Crusher
The base frames on all duty classes of our crushers are of heavy duty fabricated steel construction. All frames are substantially reinforced and braced for rugged crushing applications and years of service. The rigid construction prevents distortion of the frame during operation, resulting in maximum bearing, gear and shaft life.

Hopper of Single Roll Crusher
The hopper areas on single roll crushers are of a large, unrestricted design spanning the full width of the crusher roll.
This construction allows the machine to crush large feed lumps delivered into the hopper. The hopper is flanged at the top and equipped with drilled bolt holes for attachment of an auxiliary hopper or feed chute above the crusher. Renewable, abrasionresistant
steel wear liners are furnished on the interior hopper side walls.
Crushing Plate of Single Roll Crusher
Crushing is carried out along the full width of the extra long, curved crushing plate, preventing material from jumping away from the roll. The fabricated steel crushing plate, either corrugated or smooth faced, extends from the top of the hopper. The crushing plate has easily replaceable wear liners that may be either slotted or smooth. The slotted design reduces slabs inthe product when crushing slabby feeds.
As the sketch above illustrates, the generous throat opening is designed to accept large slabby feeds. The crushing action is a combination of slow speed impact, splitting, accomplished by teeth piercing the feed lump as material is pulled through the tapered opening between crushing plate and roll. The curved crushing plate, with wide opening at the top and narrow opening at bottom, allows for maximum reduction ratio.
Shafts and Bearings of Single Roll Crusher
Roll shafts, countershafts and hinge shafts (located at the top of the crushing plate) are made of turned, ground and polished alloy steel of ample design and size to withstand crushing forces. Self aligning anti-friction roller bearings mounted in heavy duty steel housings are bolted to the frame to support the roll shaft and countershaft. Optional taconite seals can be provided for extremely dusty or wet material feeds.
