Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond's Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product …
The rolls provide toothed patterns suited to the feed material. Single Roll Crushers generally handle larger feed sizes at higher reduction ratios in higher capacities. These machines are also great as lump breakers. Double Roll Crushers. Double roll crushers reduce primarily through compression, although toothed rolls provide some shear.
The rolls crushers we sell are used in mining and parallel industries; a double rolls crusher is a common type of equipment used as a primary crusher for sizing ore. Roll crushers are used for sizing sintered coals, soft and medium hard rocks, fertilizers and salts.The crushing material is fed on the top of the whole width of the rolls with the help of feeders.
