Jean-Paul Duroudier, in Size Reduction of Divided Solids, 2016. 3.7.4 Performance.Rod millsare used in an open circuit between crushing and theball 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.

The mill used for this comparison is a4.4-meter diameter by 13.6 meter long ball mill with a 5000 hp drive motor.It is designed forapproximately 90s.This type two-compartment mill is a state- of-the-art shell supported cement finish mill.The torque and time requirements of the mill with the ball.

Although they have the similar working principle, there are many differences between ball mill and rod mill on details. 1. Configuration of ball mill and rod mill. The proportion of cylinder shape is different. Thecylinder length-diameter ratio of rod mill is generally 1.5-2.0, while thecylinder length-diameter ratio of ball mill is smaller, onlyslightly greater than 1.

Rod millis a type of grindingmillwhose grinding media is steel bar, whileball millis steelball. 1.Rod millare 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. 2. In the two stage grinding process, if it requires grinding the ore from 20-6mm to 1-3mm in the first stage,rod...

Introduction. Therod millis loaded with the grinding media of steel bars. It consists of five parts including cylinder shell, feeding system, discharge system, main bearing and transmission system. It is available for both of the dry grinding and wet grinding fashion as the customer’s needs.

Rod millis by a rotating drum causes friction and attrition between steelrodsand ore particles.Rod millsare less common thanball millsfor grinding minerals. Therodsused in themill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller therods, the larger is the total surface area and hence ...

When themillis rotated without feed or with very fine feed, therodsare in parallel alignment and in contact with one another for their full length. New feed entering at one end of themillcauses therodcharge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rollingrodsexpend most of their crushing force on the ...

Open Circuit Rod Mill-Open Circuit Ball Mill. Thisconfiguration is employed when it is desired to produce a final ground product having a very high pulp density. This situation can be useful for various types of leaching circuits but does not normally apply to flotation concentrators. Single Stage Ball Mill. Single stage ball milling has proven to be very popular in recent years.

Sizes are limited to 3’6” x 4’ for steel ball mills, and4’ x 5’ for lined mills. “TD” mills are available with or without water-jacketing. Continuous Feed and Discharge Mills. Patterson offers a variety of Continuous Ball, Rod, and Pebble Mills for open or closed circuit grinding applications.

Therod millusually uses 50-100mm diameter steelrodas grinding medium, while theball milluses steelballas grinding medium. The length of steelrodis 25-50mm shorter than the cylinder, and it is usually made of high carbon steel with carbon content of 0.8% – 1%; the loading capacity ofrodis about 35% – 45% of the effective volume ...

Grinding Medium of rod mill. Grinding medium of rod mill. The rod of diameter from 50 to 100 mm is often used as the grinding medium, and the filling rate of rod mill is35% to 45%, while filling rate of ball mill is40% to 50%. Rod is mainly made of several materials: A High carbon steel.

Arod millfeed conveyor (4) accepts all of the ore from these feeder belts for ultimate transfer to therod mill. This conveyor is normally equipped with a weightometer (5) to monitor the flow rate of ore to therod milland ultimately to allow control of this flow.

Jun 11, 2019· In the order you have listed; aball millcan fine grind down to <400 mesh if needed, arod millwill efficiently grind to 150/200 mesh range, and a rollmillcan do a +/- 100 mesh. Theballandrod millsare similar in appearence, as a large rotating lined cylindrical tube filled with either metal balls or longrodsused as the grinding medium.
