The Bond Rod Work Index Test determines the resistance of ore to grinding in a rod mill, expressed as a work index kilo Watt hour per ton (kWh/t). The work index is then used to calculate the specific energy requirements for sizing rod mills or determining their throughput for a .
bond ball mill work index – Grinding Mill China. Bond Index Ball Mill PTBBM | Prep Tech CN. The Prep Tech Bond Index Ball / Rod Mill is designed to meet the industrial requirements to grind coal, cement and a wide variety of ores related to the Bond Ball Mill and Bond Rod Mill WORK INDEX This index is used to calculate the power.
The Bond rod mill work index is not as common as the Bond ball mill work index, and there are two different variations on the mill models expect a mill with a "wave liner", and is not compatible with mills using "smooth liners".
• The Bond Rod Mill Grindability Test determines the Bond Rod Mill Work Index which is used to determine net power requirements for sizing rod mills. The test is a closed circuit, dry grindability test, run in a standard rod mill. It can be performed at mesh sizes ranging from 4 mesh to 65 mesh. • The Bond Impact Test determines the Bond ...
The Bond Index conforming rod charge consists of: 6 rods of " diameter and 21" length; 2 rods of " diameter and 21" length; The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a waveshaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.
Rod life is maximized of rod lengthtomill diameter is maintained between to Rods wear unequally with thin rod formed at the feed end and forming an elliptical shape. Rod .
A "Bond" rod mill work index is to be determined in an apparatus with a wave liner. The author is aware of four laboratories that offer a rod mill work index test where the lining of the mill is either smooth, or smooth with a small number of primitive lifters that do not constitute a wave liner (one of the four laboratories is known to be ...
standard Bond rod mill. A Bond rod mill is by, with wave liners (of a form described by Bond), which runs at 40rpm and tilts as described below. The charge consists of 8 rods, weighing a total of Initially, a 1250ml subsample of feed is prepared for use in the first batch grind. It is ground in the mill for 100 revolutions.
83 Centrifugal force outward Fc mp 2 Dm 2 () is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg () The particle will remain against the wall if these two forces are in balance ie.
Metallurgical ContentOptimize Ball Mill Liner ReplacementLorain Shell LinersMill HEAD LINERSMill LINER BOLTSEffect of Liner Design on Mill Performance There are many different designs and styles of ball mill liners. As with grinding balls local economics and ultimately operating costs determine the best design and material to use. The initial set of liners is rarely the final design selected.
The Kaltech Intelligent Bolts, both the iBolt and the eBolt, present a true breakthrough in the real time wear monitoring of the mill liners, for the very first time. As the exclusive providers of this technology to milling operations globally, Kaltech is proud of the enhanced value we can bring to clients.

At this point the rods come to rest in relation to the shell of the mill. The liners lift the rods back to begin the cascade again. You will notice, that as you go deeper into the rod load, the rod movement becomes less and less until the movement is very slight at the deepest .
Mineral Processing Lab Homework Problems Section B: Grinding 7. Rod Mill (A): The top particle size of the copper porphyry received from roll crusher (Problem 4) is cm and is required to break down to a size of 2 mm to prepare a feed for ball mill.
Number of Lifters = 3nD for double wave liners = for single wave liners where D is the mill diameter (m). Double wave liners are more suitable for ball sizes less than 60 mm. Otherwise, single wave is preferred.
