The test determines the Bond Impact Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing crushers*.
There are two important factors in rock fragmentation: (1) total energy consumed and (2) size distribution of fragments. In a study on crushing and grinding, fracture toughness has been taken as a key index similar to the Bond Work Index. Due to many cracks dealt with, rock fragmentation is a very complicated and difficult fracture problem.

A bond is an abrasive material used to held abrasive particles together. The bonding material does not cut during the grinding operations. Its main function is to hold the grains together with varying degrees of strength. The different standard grinding wheel bonds are vitrified, resinoid, silicate, shellac, rubber, and metallic.

Quick Method For Bond Work . Abstract the bond work index is a measure of ore resistance to crushing and grinding and is determined using the bond grindability test its value constitutes ore characteristic and is used for industrial comminution plants designing determining the bond
Jan 01, 2016· Bond’s crushing work index of gypsum. 3.4. A sample of granite passing a 7.5 cm square opening screen was suspended in a Bond’s pendulum test. The length of the pendulum was 413 mm and the mass of hammers is 13.6 kg each. The sample was completely crushed when the initial position of the pendulums made an angle of 30° with the vertical.
Various vitrified grinding wheels and a crushable metal bonded wheel have been tested to show the general applicability of the method to grinding wheels with brittle bond systems.

Crushing is done in three stages, reducing to 80% passing 2 cm (3/4 inch). Rod and ball mills take the ore down to an 80% passing size of 60 microns (270 mesh). METHODOLOGY The Bond equation is a useful tool to compare predicted and actual values of energy requirements for each step in taconite comminution. Crushing and grinding
Milling Equipment : bonds crushing law and work index quarry grinding plant A class of machinery and equipment that can be used to meet the production requirements of coarse grinding, fine grinding and super fine grinding in the field of industrial grinding.
Grade: The term "grade" as applied to a grinding wheel refers to the tenacity or hardness with which the bond holds the cutting points or abrasive grains in place. It does not refer to the hardness of the abrasive grain. The grade shall be indicated in all bonds
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
Form crush dressing is a method to profile diamond grinding wheels. Especially for complex profiles with intricate details and high accuracy an improved form crush profiling system has been developed.
