The Bond low-energy impact crushing work index more informally the Bond crushing work index is not as common as the Bond ball mill work index and it is a notoriously noisy test. The test is a per-specimen test where individual specimens of prepared rock are hand-picked by the test operator and placed into the apparatus.
Crushing energy using Bonds index 0 where rij and eij are six components of stress and strain. It is assumed that a 10 cm height cubic shape specimen In the processing zones of crushers such as Jaw Roll or and a 10 cm diameter spherical shape specimen are crushed Gyratory crushers the rock particles are mainly crushed as between two rigid .

Grindability Index Test Method amp Procedure - 911 Metallurgist. The proposed grindability test uses the Bond standard test mill and a quantity called . that the orcs concerned do not conform to the Bond Law of Comminution. .. required for many crushing and grinding operations. . in stages to finer than 6 mesh 335 mm and ground under specified conditions in a laboratory ball mill.
Apr 29 2013 crushing experiments show that the capacity of a jaw crusher is dependent .. they are empirically based laws that only fit experimental data over a limited range of .. free to pass through the crushing chamber at any time the breakage process the most utilized for jaw crushers compressive strength and the work index. More detailed.
The crushing energy in mineral processing industry is usually determined by empirical Bonds index regardless of the mechanical properties of a rock.
The Bond low energy impact crushing work index test is specified to be performed on rock specimens between 50 mm and 75 mm in effective diameter. NQ-diameter drill core frequently used in mineral exploration programs does not meet that specification it being 45 mm diameter or less.

The Bond Index conforming rod charge consists of 6 rods of 1.25 diameter and 21 length. 2 rods of 1.75 diameter and 21 length. The grinding jar for the Bond Index Rod Mill is 12 x 24 in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.

crusher were compared with those of the Bond crushing energies estimated from the Bond crushability index of the rocks. Also the effect of the Bond crushability index on the estimated crushing energy of the rocks was studied. Materials and methods In this work nine different rock specimens were obtained from some mines in Iran.
