The basic parameters used in ball mill design power calculations rod mill or any tumbling mill sizing are material to be ground characteristics Bond Work Index bulk density specific density desired mill tonnage capacity DTPH operating solids or pulp density feed size as F80 and maximum 'chunk size' product size as P80 and maximum and

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.

The rod mill test gave RWilab of kWht and a ball mill work index BWilab of kwh t. Accepting that the rod mill work index applies to size reduction of the circuit feed down to the rod mill test product P80 of 1050 um and that the ball mill work index applies from this size to the circuit product size, calculate the standard Bond energy ...

Laboratory Rod Mill: Working Principle: The laboratory rod mill is a rotating drum that causes friction and attrition between steel rods and ore particles. But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for

The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing mm (6 mesh) to product size in the range of 45150 µm (325100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work ...

Dec 30, 2012 · Posted December 29, 2012. I would suggest that you build a rod mill if you want to get the material down to a fine power, a ball mill usually is used to make bigger item smaller, big rocks down to little rocks, and then the material goes into a rod mills to take it .

This is substantially higher than the 22 Bond work index of the sample used in the testwork. A conventional SAG/ball mill circuit for this ore will be extremely inefficient, and for this reason, this circuit was rejected in favour of a conventional rod mill/ball mill circuit."

The rod mill test gave RWilab of kWht and a ball mill work index BWilab of kwh t. Accepting that the rod mill work index applies to size reduction of the circuit feed down to the rod mill test product P80 of 1050 um and that the ball mill work index applies from this size to the circuit product size, calculate the standard Bond energy ...

JeanPaul Duroudier, in Size Reduction of Divided Solids, 2016. Performance. Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture.

Essa® Bond TestWork Equipment. 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. These are empirical indices determined by close circuit grindability tests developed by in the mid 1930's.

The average ball mill work index given as 16 kWh/short ton = kWh/tonne; The relationship between A×b and Wi RM for Andean copper porphyries can be used to determine the following rod mill work index values. A×b of Esperanza ore; avg= 39; becomes Wi RM = kWh/tonne; No crushing work index is given.

Rod Mills are similar with the Ball Mills xcept they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is .

The types of mills are distinguished by their working principles: by pressure, impact, hammer, or shear. Mills could be equipped with a screen for grain size control and separation. The FAM product range includes impact mills, roller mills, hammer mills, ball mills and rod mills, as well as appropriate roller screens.

Jan 01, 2016 · Rod Mill–Ball Mill Circuit: Consider the setup in Example along with the following additional data: Grindability index for the ball mill = kWh/t. Product size from the ball mill = 150 μm. Determine the size of the ball mill operated in closed circuit. Solution Step 1. The discharge from the rod mill is the feed to the ball mill.
