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.

Micronization of a Soft Material: Air-Jet and Micro-Ball Milling. Nov 24, 2010 ... In a ball mill, grinding energy is transferred to materials through media such as balls, rods, pebbles, by moving the mill .

The industrial comminution process under consideration has the following four units: Rod mill, Ball mill, hydro-cyclones, and water sumps. Fresh feed from the bin is fed to the rod mill along with water. The slurry generated from the rod mill is mixed with the slurry from the ball mill in a primary sump.

Mill Speed - Critical Speed. Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.

The Bond Index conforming rod charge consists of: 6 rods of 1.25" diameter and 21" length; 2 rods of 1.75" diameter and 21" length; The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.

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.

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 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 ...

Figure 8.2 Media motion in the tumbling mill. 8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

Oct 12, 2019· At present, the most widely used grinding equipment in the dressing plant is ball mill and rod mill. As far as the working principle is concerned, both ball mill and rod millare the same. The grinding medium (steel ball or steel rod) installed in ...

Comparison between Rod Mill and Ball Mill. 2014-01-03. 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 w-sn ore and rare metal in the reselection or magneticore-dressing plant in order to avoid the damage caused by the over crushing.

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.

Jul 20, 2019· 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.

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 all-steel construction.

How to decrease particle size of alumina powder with ball milling? ... both wet and dry milling will achieve your particle size goal, so if the powder will be used in a slurry, then wet milling is ...

milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is

In the fine grinding production line, when the product size is less than 0.5mm, 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
