Comparison between Rod Mill and Ball Mill. . Rod mill is a type of grinding mill whose grinding media is steel bar, while ball mill is steel ball. 1. Rod mill are usually applied to grinding the wsn ore and rare metal in the reselection or magneticoredressing plant in order to avoid the damage caused by the over crushing.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as .

Ball/Rod mill Literature . The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batchwise, rapid grinding of mediumhard to very hard samples down to finest particle sizes.

Ball mill and rod mill solutions are available here at APT, providing an effective means for grinding and blending materials in preparation for mineral liberation, from rock to dust. APT specifies and designs the entire circuit around the mill, to ensure that the target product size is achieved. Ava

F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] 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 grinding minerals.

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.

Unlike the ball mill, the grinding medium in the rod mill is a steel rod, so the working characteristics are significantly different from those of the ball mill. Since the steel balls are in point contact, the steel rods are in line contact. When the steel rods are sandwiched between the steel rods, the coarse particles are first broken, and ...

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.

The types of Rod Mill discharge trunnions are: overflow, perforated overflow, return spiral, grate, and peripheral. Thus the engineer can fit any one of fifteen variations of sizes and type of discharging a rod mill, into the problem on which he is working. The superiority of the Steel Head Rod Mill is due to the allsteel construction.

The TM 300 Drum Mill is used for the preparation of granules and powders. The grinding process is performed either in dry or wet conditions. The drum mill can be operated either as a Ball or as a Rod Mill by using the corresponding module. A sufficient number of balls or rods is required for an effective grinding process.

2018 mm size rod mill. ... HM Mahesh in Synthesis of Inorganic Nanomaterials 2018 3611 Ball Milling A ball mill is a type of grinder used to grind and blend bulk material into QDsnanosize using different sized balls The working principle is simple impact and attrition size reduction take place as the ball drops from near the top of a rotating ...

The milling equipment which are widely used in the mineral processing plant are the ball mills and the rod mills. The two have similarities in shape and grinding principle, but there are also differences in structure, performance, use and so on.

Ball Rod Mills are designed for simple long term operation The standard drive unit accepts a variety of different barrel sizes listed below. 200 x 200 Ball mill 200 x 250 Rod mill (Pictured) 250 x 250 Ball mill 250 x 300 Rod mill 300 x 300 Ball mill 300 x 360 Rod mill

In the fine grinding production line, when the product size is less than, the grinding effect of the ball mill is greater than that of the same size rod mill. That is, the products of the ball mill are more refined, and the products of the rod mill are rougher, but more uniform. (3) Choose according to production method

The flowsheets were as follows: (1) Rod mill followed by wet magnetic separation with ball mill grinding of the magnetic concentrate; (2) HPR closed with a 3 mesh screen followed by wet magnetic separation of the screen undersize and ball milling of the magnetic concentrate; (3) HPR closed with a 3 mesh screen with the screen undersize being ...

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50% of the mill volume and its size depends on the feed and mill size.

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 grinding load. Rods in place weigh approximately 400 pounds per cu. ft. .

The geometry of a mill with conical ends is shown in Figure The total volume inside the mill is given by Vm 4 D2 mL 1 2(Lc L) L 1 (Dt/Dm) 3 1 Dt/Dm () The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill.

Jun 30, 2017· The Ball and Rod Mill type LMBRM is a process and laboratory machine, which is suitable for milling and homogenizing soft, fibrous, hard and brittle materials in dry and wet phase.

(1) Rod mill is usually selected in order to prevent over grinding in gravity or magnetic separation plant of tungsten tin and other rare metals mine; (2) In two stages grinding, the capacity of rod mill machine used in the first stage grinding is larger than ball mill''s; (3) In some cases, rod mill .
