Providing a crushing ratio of up to 6:1, Single Roll Crushers reduce large size particles in the feed to a medium size, while producing a low percentage of fines. The Single Roll Crusher design is very effective in reducing slabby material because of the varying tooth height and interrupted opening between the roll teeth and the corresponding grooves in the crushing plate liners.
The Single Roll Crusher, which was originally patented by Samuel Calvin McLanahan in 1894, is designed for operator safety and simplicity. Complete with safety guards, the Single Roll Crusher features an automatic toggle mechanism that allows the crushing plate to hinge open, pass non-crushable tramp material and return to the previous setting for continued operation.
This unit is designed to make crushing simpler and more effective. When properly fed in the direction of the roll rotation, the crushing action is carried out along the full width of the curved crushing plate assuring maximum capacity. Properly sized teeth grab the incoming feed and pull it through the crushing zone without hesitation. The crushing plate includes easily reversible and replaceable wear liners for simplified maintenance. McLanahan Single Roll Crushers also feature hydraulic product size adjustment to perform relatively simple changes to the crusher setting if required.
McLanahan selects the proper duty class of Single Roll Crusher based on provided application data and extensive field experience. A fully-equipped application research laboratory allows for crushing tests to make sure McLanahan can provide the best possible custom engineered solution.
Cobra Single Roll Crushers are the lightest-duty in the McLanahan line of Single Roll Crushers. They are ideal for wet, sticky feeds and for processing materials such as clean coal, petroleum coke, sulfur, rosin, foundry cores, frozen agglomerates and other friable materials.
Black Diamond Single Roll Crushers are designed to handle medium-hard materials such as ROM coal with shale and slate, salt, and phosphate rock.
Super Black Diamond Single Roll Crushers are designed to handle hard to medium-hard materials such as shale, gypsum, ROM coal and phosphate rock.
Shale King Single Roll Crushers produce primary and secondary sized products and are designed specifically to process rock. They are ideal for oil shale and materials of similar hardness.
Rockmaster® Single Roll Crushers are the heaviest-duty model in the McLanahan line of Single Roll Crushers. They are ideal for the most severe crushing applications and reduce extremely hard material and typical mine refuse.
