What are the differences between ball mill and 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 is 35% to 45%, while filling rate of ball mill is 40% to 50%. Rod is mainly made of several materials: A High carbon steel
7 Differences Between Ball Mill and Rod Mill Xinhai
Grinding medium of ball mill and rod mill The rod mill usually adopts the steel bar with a diameter of 50-100mm as the grinding medium, while the ball mill often uses steel ball as the grinding medium. The difference on grinding medium is the main difference between the ball mill and rod mill.
Ball Mill vs Rod Mill How To Choose Ball Mill or Rod
The rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium. The length of steel rod is 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 of rod is about 35% 45% of the effective volume of rod mill.
Ball Mills vs Rod Mills
When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the
The difference between a rod mill and a ball mill_cement
Rod mill usually USES steel rod with diameter of 50-100mm as grinding medium, while ball mill USES steel ball as grinding medium. The difference of grinding body is the main difference between the two.
Comparison between Rod Mill and Ball Mill ore
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. 2.
rod mill vs ball mill Redmans
Rod mills are less common than ball mills for grinding minerals.
Mill (grinding) Wikipedia
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency
THE EFFECT OF BALL MILL OPERATING PARAMETERS ON
studied include mill rotational speed, ball size, mill I charge and wet versus dry grinding. Breakage rates have been determined experimentally utilizing a SEM—IPS image analyzer. The mineral sample used was acquired from ASARCO's Young Mine which is located in Jefferson City Tennessee. It was a binary ore consisting of sphalerite and dolomite. Batch grinding experiments were conducted to

* Mills come along with a control panel and has an automatic lubrication unit. * Ball/Rod Mills can be specially designed for wet or dry grinding. Compared to similar equipment, Ersel Ball/Rod Mills provided low energy consumption and high efficiency, as a result of our improvements based on our R&D studies and process experience.
grinding ball comparison
Ball Mills vs Rod Mills. Stage grinding which is by repeated passes followed by removal of the finished material, is the best means of obtaining selective grinding. These terms must not be confused with differential grinding, which has to do with the relative grinding rates of two or more minerals in an ore. Rod Mills = Selective Grinding. Ball Mills = Non-Selective Get Price. large scale

Rod mills, how they function Mine Engineer.Com
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. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of
Grinding Circuit an overview ScienceDirect Topics
A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting. Oversize and undersize materials are separated using a screen; oversize material goes back for further grinding.
Rod Mills for coarse grinding FLSmidth
Our Rod Mills are available in multiple diameters to fit the needs of your operation. Grinding, primarily by attrition, Rod Mills require comparatively low levels of power to operate. Rod Mills can be either wet or dry designs. Once replaced by AG and SAG mills, Rod Mills have had a
Grinding mills for mining and minerals processing
Every mining operation has a unique grinding process. Variable needs require versatile grinding equipment. peter&x offers flexible autogenous (AG) mills, semi-autogenous (SAG) mills, ball and pebble mills, as well as stirred mills to fit your needs.
Difference Between Sag Mill vs Ball Mill mech4study
The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially. Interior of the drum uses the lifting plates. These plates inside the drum are responsible for picking the grinding material up to fall down again throughout the rotations. Repeated collisions between the steel balls and raw materials (ore
TECHNICAL NOTES 8 GRINDING R. P. King Mineral Tech
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 particles of media the rods, balls or pebbles. This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily by crushing and attrition. In autogenous grinding machines
