O Bond Rod Mill Work Index é um teste padrão para determinar o Índice de Trabalho de moinho de barras para uma determinada amostra de minério.Ele foi desenvolvido por Fred Bond, em 1952 e modificado em 1961. O WI é uma medida da resistência do material à britagem e à moagem.
As in ball mills, the power draft of a rod mill is the product of capacity and work index, which is the energy required to break a mineral of a given size to the required size. The mill power is also increased by increasing the rod charge and the mill speed, while the mill power and capacity are both increased with increasing mill length.
FIGURE 5: BOND ROD MILL WORK INDEX v. UNCONFINED COMPRESSIVE STRENGTH 0 100 200 300 400 UCS (MPa) 5 10 15 20 25 30 35 WiRM (metric) The lack of fit observed relating the crushing Work Index was expected to carry over to the other Bond Work Indices. Figure 5 displays the plot of rod mill Work Index (Wi RM) versus UCS. These
Bond's approach consists of determining the ore hardness characteristics, or Work Index (Wi) via standardized laboratory testwork. The full suite of Bond comminution tests provide the Ball Mill Work Index (BWi), the Rod Mill Work Index (RWi), the Crusher Work Index (CWi) and the Abrasion Index …
W is the work index measured in a laboratory ball mill (kilowatt-hours per metric or short ton) P 80 is the mill circuit product size in micrometers; F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles.
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. The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill Work ...

Determining the Bond work indexes of a sample involves tests using laboratory scale grinding circuits. A unit weight is determined by achieving maximum packing of the prepared ore sample; the unit weight is then fed into the circuit, with undersized product being replaced by …
Generally, Bond work index is a common method for selecting comminution equipment as well as estimation of grinding efficiency and calculating required power. In the current research, a simple, fast and accurate procedure is introduced to find the
The only information available for the comminution parameters such as Bond Rod Mill Work Index (RWi), Bond Ball Mill Work Index (BWi), Bond Abrasion Index (Ai), and Bond Crushing Work Index (CWi) tests is one BWi test conducted on the one sample tested by SGS Mineral Services.

This 12" x 12" ball mill is universally used for grindability testing and determination of the Bond Work Index. Mill comes complete with ball charge, and control panel with automatic revolution counter.
The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

Bond Work Index Tables (Wi) - Free download as PDF File (.pdf), Text File (.txt) or view presentation slides online. Here there are given tables from various sources for the Bond work index values of mining materials (ores, industrial minerals and rocks). These work indexes can be used for the determination of tumbling mills (rod, ball mills) power.
Bond Rod Mill Work Index, RWi, kWh/t 18.1 Table 1. Example of AG/SAG Ball Mill Circuit Wio Calculations [1] [2] ABstrAct Optimum use of power in grinding, both in terms of grinding efficiency and use of installed capital, can have a large effect on profitability. Mill operators have long used operating work indices to evaluate grinding circuit
