• Grindability as indicated by the bond ball mill work index (BWi) ranged from 10–35 kWh/t, with the majority between 15 and 27 kWh/t. No clear relationships in terms A*b and/or BWi was identified with geological aspects logged from the drill core such as weathering, lithology, alteration, alteration intensity, veining or combinations of these.

Bond Ball Mill Index - JKTech. A Bond Ball Mill Index Test (BBMWI) is a standard test for determining the Ball Mill Work Index of a sample of ore. The BBMWI It was developed by Fred Bond in 1952 and modified “Crushing and Grinding Calculations Part I and II”, British.
The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...
Bond Testwork Equipment Welcome to Mineral Stats … Internationally accepted mineral metallurgical standard test procedures to determine the physical properties of ores include the Bond ball mill work index and the Bond rod mill work index.

the relative grindability of different ores in ball milling (Bond, 1961 and Rowland and Kjos, 1980) To use the Bond ball mill work index to determine the ball mill specific energy required for a particular grinding task, the Bond equation must be used and the various relevant efficiency factors applied. In
Oct 15, 2015 The particle size range of the biomass particles (prior to densification) was obtained using the British standard BS EN 16126:2012 . 2 litres of boiling deionised water was poured over 300 1 g of each pellet sample and then soaked for 24 h. The samples were then dried at 35–60 C until they reached 5–15% moisture content.The samples were then split into two portions; 150 g was used to ...
typically used. The rod mill work index is computed with an equation very similar to that of the ball mill test, as follows: It is common to observe a difference between the rod mill and ball mill values for a given ore type. These differences may be caused by a variation in ore hardness by size (12.5mm for RWI and 3.35mm for BWI), and/or grain ...
Grinding Solutions offers the following tests for SAG mill testing and/or sizing. JKTech Drop Weight The JKTech Drop-Weight Test measures the breakage characteristics of an ore for five size fractions in the range of 13 to 63 mm, at various energy inputs (0.1 to 2.5 kWh/t). The ore-specific parameters derived from these measurements can be used in grinding circuit...
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.
• the bond ball mill work indices determinations gave reasonably reproducible results, • significant variation was observed in the measurement of the bond rod mill work index on at least one sample tested, and • large variations in abrasion index and crushing work index were due to variations in the test method across the laboratories.

Technical Information. Information about sample size, calibration, precision and accuracy. The SMC Test is the most widely-used comminution test in the world for AG & SAG Mills, HPGRs and Crushers. The SMC Test was developed to provide a range of useful comminution parameters through highly controlled breakage of rock samples.

JK Bond Ball Mill Test Since its introduction in the 1960s, the Bond Ball Mill Work Index (BBMWi) parameter has been extensively used in predicting ball mill power draw. Use of Work Index Along with comminution circuit design the work index parameter is widely used in tracking mill performance. Due to the age and lack of controls for the test,
