2017.4.1 As a result, the forces acting in a double roll crusher could be much higher, at least locally, as one would expect for normal single particle comminution. This should be true even if the DRC is, as usual, starvation fed with just about 15 per cent of the crushing gap filled with solids. 3. Crushing and bearing forces.

2015.10.28 The most important characteristics of a primary crusher include the capacity and ability to accept raw material without blockages. A large primary crusher is more expensive to purchase than a smaller machine; for this reason, investment cost calculations for primary crushers are weighted against the costs of blasting raw material

where L and B are the length and the width of the jaw crusher charging opening, m. Taggart formula takes into account just two structural settings of the crusher. However, it is quite fair for crushers of medium size but not very big and not very small. From the theoretical formulas of capacity calculation the formula of T. Simons became widely

2019.6.15 Next, the two-toothed roll crusher was optimized based on the framework proposed by the Whiten model. The reasonable rolls gap and teeth length should be 75 mm and 23 mm, respectively. Further, a physical model of a two-toothed roll crusher was established to obtain the optimized roll diameter; it was later found to be >660 mm.
