The Bond Abrasion Index is a measure of how readily a rock sample will wear away steel that comes into contact with it. It is conventionally used to estimate the liner
Get PriceBond Abrasion Index Test Machine. The Bond Abrasion Index, devised by F.C. Bond in the 1940‘s, quantifies the abrasivity of an ore. The index can be used to
The Abrasion Index’s denotes the weight loss of the paddle made of clearly defined steel during one hour of rotating in a testing drum with material being
A clear definition of the required crushing capacities and the desired product quality can be precisely determined by using the Bond Index test methods. Using the
Oct 08, 2015 The Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond
Mar 31, 2016 The nature of the breakage will be skewed towards abrasion breakage in the smooth liner designs, whereas the wave liner will have more attrition (and possibly
The Bond's standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatt-hours per short
a method using Bond Indices than adding a single factor of 1.25 to arrive at the AG/SAG speciﬁ c energy. In 1991 the Canadians developed the SAGPower Index (SPI)
From Bond abrasion index tests, it is possible to determine a wear rate using the following empirical equation (1) ... Estimation of the wear rate associated with
The Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process
BOND ABRASION INDEX TESTER 5 3. TECHNICAL FEATURES 3.1. CONSTRUCTION The housing of ABRASION INDEX TESTER is made of steel plate varnished with high resistant painting. Protective equipment The milling chamber of the ABRASION INDEX TESTER is enclosed by a strong covering door. Starting of the machine is possible only with the door closed. 3.2
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
Dec 07, 2018 porphyry orebodies. Total of 38 Bond work index tests, including duplicates, were done. Standard Bond ball mill test procedure were carried out on crushed (-3.35 mm / 6 mesh) material at different screen closing sizes (300 m, 212 m, 150 m, 106 m, and 75
