BOND WORK INDEX The amount of energy required by plant to crush material LOS ANGELES VALUE The Los Angeles test is commonly used to evaluate the hardness of aggregates to find the suitability of aggregates for use in road construction. Therefore, the road aggregates should be hard enough to resist abrasion. UCS (UNIAXIAL COMPRESSIVE STRENGTH)
I have not found the Bond models for mill liner wear to be useful and it's normal to assume a certain number of liner change outs per year, and factor this up and down depending on generalized assessments of the wear environment (consider ore hardness, feed size, ball size/surface area, abrasion index, mineralogy and water quality).
Bond Work Index Tests. Grinding Solutions offers a range of Bond Work Index Testing from crushability and abrasion to ball and rod mills. For more information on the tests please see below: Bond Low Energy Impact Test. The Bond Low-Energy Impact test can be used to determine the Crusher Work index (CWi), also known as the Impact Work Index.
used rock abrasion tests is the Cerchar abrasion index (CAI). This test is used for estimation of bit life and wear in various mining and tunneling applications.
granite, feldspar and quartz were tested for hardness, abrasion, compressive strength and modulus of elasticity and the bond work index of these samples were estimated. The value of Bond work index of the above samples has shown a variation from 10.8 kwh ton-1 for bauxite (high abrasion value and low compressive strength) to 20.4 kwh ton- 1

JKTech Laboratory Services Bond Ball Mill Index Test (BRMWI) 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 is a measure of the resistance of the material to crushing and grinding. It can be used to determine
This Table of Ball Mill Bond Work Index of Minerals is a summary as tested on 'around the world sample'. You can find the SG of each mineral samples on the other table.
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.

White Iron Wear Parts, BiMetallic Wear Blocks/Plates ... Bimetallic white iron wear parts are unique wear resistant materials in that they combine very high wear resistant qualities of a high white iron (ASTM A532 15/3CrMo, 700BHN63HRC) with a weldable high impact toughness mild steel through vacuum brazing to create a product that is exceptionally resistant to impact and abrasion while retaining.
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 and media wear rate in rod mills, ball mills and crushers.
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.
In general, Bond's work index is used to determine the grinding efficiency and also to calculate the power requirement. The process is very time consuming and it requires skilled labor and specialized mill. A systematic investigation was carried out to predict Bond's work index using simple field measurable properties of rocks.
Overview. The Los Angeles (L.A.) abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA.. Figure 1: L.A. abrasion testing equipment.
Bond Abrasion Index This test is used to determine the abrasiveness of a material in relation to metal wear during comminution Correlations are available in graphical form between the abrasion index and metal wear rates on crushers, mill liners and grinding medium for both wet and dry grinding.
The JK Drop Weight Test measures the impact and abrasion parameters for a specific sample of ore using two separate methods: • The abrasion breakage parameter, ta, is determined by a tumbling test (Note this is NOT the Bond Abrasion Index test).

The abrasion index gives an indiion of the abrasiveness of the material and is used for estimating the service life of wear parts for crushers. Abrasiveness gives an indiion of the abrasiveness of the rock material. The Bond work indices (or "impact work index") can be used for estimating the crushability of material and the crusher's ...
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 Bond Index test procedures it is possible to calculate crushing / abrasion behavior of mineral samples. This knowledge is essential to define the required ball mill layout and ...
