Double Roll Crushers are designed for single-pass size reduction of medium-hard to hard materials such as rock or ore to a nominal minus 10 mesh Topsize is approximately 13mm and final fineness typically passes a No 10 (2mm) opening, depending on material type
Double Roll Crushers reduce primarily through compression, although some shear is obtained with toothed rolls Rolls for these crushers come in combinations of smooth, corrugated, and toothed designs Double Roll Crushers produce a finer product at lower reduction ratios and capacities
Double Roll Crusher The American Pulverizer Double Roll Crusher is ideal for primary and secondary reduction of ROM coal, washed coal, middlings, screenings, slag, moist clay, limestone, cement, potash, rock, sulfur, lignite, pyrite, and other materials where minimum fines are required
Aug 24, 2011 · The Double Roll Crusher is typically used as a secondary or tertiary crusher due to a lower reduction ration (typically 4:1)
Dec 28, 2012 · roll to be held back from the solidly mounted roll Crushing rolls Unlike jaw and gyratory crushers, where reduction is progressive by repeated pressure as the material
Based on TAKRAF's significant experience in crushers and crushing plants, the world's second largest roll crusher for ductile and abrasive oil sands, with hard rock of up to 200 MPa, was successfully installed into four separate existing crushing plant locations to crush lumps of up to 2,500 mm down to a …
Crushing by the Double-Roll Crusher is primarily accomplished by compression and consist of two heavy metal rolls of equal diameter placed horizontally which are rotated towards each other at same or at different speeds The rolls are mounted on heavy shafts One of the rolls is motor driven while the other roll rotates due to friction
high capacity mining silica sand ball mill t is widely used for the grinding of cement and silicate products; new building materials, refractory materials, fertilizer, ferrous and nonferrous metal and glass ceramics and other grind-able materials withdry or wet grinding
There are in four designs of roll crushers: single roll crushers, double roll crushers, triple roll crushers, and quad roll crushers Roll Crushers are built to handle primary, secondary and tertiary stage crushing of friable materials such as coal, salt, clay, bauxite and more
Both single and double-roll crushers have been extensively developed for crushing coal, coke, shale and similar soft and friable materials These machines resemble in general form the roll crushers we have described, but they are of course much lighter, and their mechanical details …
