This difference between Bond Rod mill and Ball mill or Hardgrove mill curve slopes is presumably due to the coarser feed particle size of the Rod mill experiments (X 80 = 2.3 mm, X max = 7 mm) unlike Bond ball mill feed size (X 80 = 2 mm, X max = 3.15 mm). The coarser particles contain more cracks, dislocations, which increase in number by the compression stresses of the rods in the mill

Correlations for the Grindability of the Ball Mill
The reduction in size due to ball mill grinding was found to be better for wet grinding than dry grinding based on specific rate of breakages obtained. The sub sieve morphology of particles in

Technical Note Why is the Bond Ball Mill Grindability Test
The Bond Ball Mill Grindability Test is probably based on a laboratory grindability test first described by Maxson, Cadena and Bond (1934). The two tests are very similar. Both are locked– cycle grinding tests. In both tests, the top size of the feed to the laboratory mill is 3.35mm, and the volume of the mill feed is 700cc. Both tests stop when they have reach equilibrium. The mill used in

Oct 15, 2015 · Grindability tests which aim to analyse the grindability of biomass to 75 μm are flawed, as the target size for optimal combustion of biomass and the setting for the classifier output from full scale mills is an order of magnitude of higher than this. The BWI test can be used to analyse the mill behaviour of biomass in a tube and ball mill.

Relationships between comminution J energy and product
The standard Bond ball mill grindability test is a closed circuit dry grinding test with a 250% circulating load. The standard procedural outline of the test is stated in (Bond) 1961. The work index for a ball mill, Wi, is then calculated from the following equation. [7] where P is the closing sieve size ( m), Gbp is the grindability (net g/rev.), F80 and P80 are the 80% passing size of the

Bond Ball Mill Index Test  JKTech
Measuring ore grindability in balls mills. The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen. The Bond Ball Mill Work Index can be

Investigation of iron ores based on the bond
Grinding is a process of reduction of lumps to powder depending on the requirement of particle size and particle shape. The present investigation involves the identify the physical properties of three different types of iron ores by using Bond ball mill. The result shows that the maximum Bond work index of 14 KWh/mt was obtained for `A' type iron ore sample.

Based on this equation it is possible to calculate, for example, the specific energy requirement for a given grinding duty, BBMWI, feed size and required product size. It is then possible to determine the size of mill required based on throughput, and therefore motor power. The standard Bond Ball Mill Work Index test procedure is firstly to stage crush the feed to minus 3.35mm, and size a
