Mar 08 2021 Recommendation of ball mill and rod mill Ball mill and rod mill are suitable for different materials 1. Selection by materials hardness Ball mill has a strong adaptation of material and it is suitable for grinding hard materials such as slag iron ore copper ore etc. Rod mill is suitable for grinding brittle material such as rare metals. 2.
The product size distribution is narrower than a ball mill but significantly coarser. Most are overflow discharge type. Length-to-diameter 1.4 to 2.3. Mill length 7 meters. Rod Mill-Ball Mill Circuits Diagrams of mill circuits image 135-8-2
How To Choose Ball Mill or Rod Mill. Generally users can choose ball mill or rod mill on base of their raw materials product size and properties of the equipments. 1. According to Ore Properties. To a great extent the hardness and granularity of ore will affect the selection of grinding equipment.
Ball mills are simple in design consisting of horizontal slow rotating vessels half filled with grinding media of to 1.5. The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition.

Design Method of Ball Mill by Discrete Element Method collected. The diameter of the gibbsite powder was measured using a Master Sizer 2000 Sysmex Corpora-tion. Details of the experimental conditions are given in Table 2. Results and Discussion 1. Effects of Fins on Ball Motion in the Mill To predict ball mill grinding behavior using the dis-
May 19 2020 The ball mill liner replacement should in time when the lining plate is excessively worn. Therefore the selection and design of mill liners have always been of great concern to users. Function Design of Ball Mill Liners. As one of professional ball mill liners manufacturers we summarize the main functions of the three-point ball mill liners.
Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition and broken and worn rods must be removed.
Vibration ball mill also known as a vibrating ball mill or vibratory ball mill is a kind of ball mill machine that uses the high-frequency vibration of the cylinder to make the grinding medium in the cylinder impact the material by inertial force.. Vibration ball mill is a new type of high-efficiency and energy-saving grinding equipment. It has obvious advantages over traditional rotary ball .

Jul 03 2017 The average particle is subjected to an action similar to many sets of rolls in series before it is discharged. Because of this the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids or interstitial space within a rod load are approximately half those in a ball mill

All flanges are double welded as well as steel head to shell note design. Tumbling Mill Rod or Ball Mill TYPE E Has quadruple flanged construction. This also furnishes mill heads in two sections flanged and bolted in the center. All flanges are double welded. This type also reduces difficult transportation problems. Ball Mill amp; Rod Mill Liners
Feb 20 2017 The rod mill has been extensively used for the reduction of coke breeze in the 8-mesh to 20-mesh size range containing about 10 moisture to be used for sintering ores. SMALL BALL MILLS. Grinding by use of nearly spherical shaped grinding media is termed ball milling. Strictly speaking such media are made of steel or iron.
Either the End or Center Peripheral discharge rod mill can be used for wet or dry grinding. Whatever the type the rod mill is used to produce a coarse product whereas the ball mill is used to produce a finer product. Should a ball mill grind be required the relationship of the length to the diameter of the mill is

Rod mills are very similar to ball mills except 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 maintained at 1.4 to 1.6.
For both wet and dry ball mills the ball mill is charged to approximately 33 with balls range 30-45. Pulp crushed ore and water fills another 15 of the drums

Ball mills 5.5 m 18 ft in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills particularly when the large mills carry 40 by volume ball charges. This paper will explore factors used in scaling up ball mills showing where the advantages of one factor can possibly be negated by another factor.
