Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...

Manufacturers tend to use rules of thumb to de-rate crusher capacities for the treatment of highly competent ores that display high Bond crushing work indices (CWi). One such rule is the following: de-rate = (16/CWi)^0.5. However, care is required when using this rule as CWi test methods vary and simplistic approaches do not address all of …

A cubic yard is a measurement by volume (Or most simply put, a measurement by size) 2. A ton is a measurement by weight. 3. A "/" sign means 'per,' so 1.5 TONS/CY reads 1.5 TONS per Cubic yard which simply means there are 1.5 tons per (for) every cubic yard of material. Fortunately, a cubic yard of material has a conversion factor (unit ...

The evolution of the variation of the grain-crushing rate depends on the applied load. Therefore, the method of evaluation of the crushing rate must also depend on the applied load. For Fig. 7 by comparing the results of the two loadings 40 kN and 20 kN, the results are very close to the point that they are almost the same. This can be ...

4.4 Jaw Crusher Capacity Estimation. The capacity of jaw crushers is a measure of the mass or volume of crushed material produced in unit time of operation. The capacity is primarily a function of: 1. crusher design characteristics such as width and depth of the crushing chamber, 2. open and closed side settings, 3.
