The grinding media of rod mill is a steel section, and the ceramic ball mill is the ceramic ball, as is shown in the following picture. The rod mill media and ceramic ball mill media. Appearance ratio: Rod mill, whose appearance is the same as that of the industrial ball mill. The difference is that the ratios of cylinder shape are different.
Sep 05, 2018· Daily maintenance of the ball mill: 1. Inject the grease into the motor bearing and pinion bearing before starting each time. The other oil filling parts must be well sealed and kept clean. ball mill,wet ball mill, dry ball mill, grinding ball mil...
The ball mill is not suitable for the reprocessing line of metal dressing because of its fine grinding materials. summary Understand the difference between ball mill and rod mill, and lay a foundation for the selection of equipment.
RoM Ball mills – a comparison with AG/SAG Milling ... Most of the earlier plants utilised conventional ball mills or rod mills for ... differences between this mode of mill operation to that of ...
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
Fri Difference Between Ball Mill And Rod Mill Ore Processing 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 particles of media - the rods, balls or pebbles. This motion can .
The grinding media of rod mill is a steel section, and the ceramic ball mill is the ceramic ball, as is shown in the following picture. The rod mill media and ceramic ball mill media. Appearance ratio: Rod mill, whose appearance is the same as that of the industrial ball mill. The difference is that the ratios of cylinder shape are different.
Ball mill and rod mill are the common grinding equipment widely used in the mineral processing plant. They are similar in shape and grinding principle, but also different in structure, performance and application. Here are seven differences between ball mill and rod mill to tell you how to choose the ball mill and rod mill.
Aug 25, 2016· The characteristic differences between open, and closed, circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade what is the difference between ...
Difference Between a Rod Mill and Ball Mill Rod Mills has a very define and narrow discharge product size range Feeding a Rod Mill finer rocks will greatly impact its tonnage while not significantly affect its discharge product sizes The 35diameter rod of a mill, can only grind so fine.
The Difference Between Rod Mill and Ball Mill. The rod mill and ball mill are both used in the ore grinding process. According to different working conditions, rod mill is suitable for coarse grinding but the ball mill is suitable for fine grinding. The reason is that the grinding medium of rod mill is steel bar and the contact is line contact ...
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 particles of media - the rods, balls or pebbles. This motion can be characterized as collision with breakage .
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.
Critical rotation speed of dry ball-mill was studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is a function of a ball .
Ball Mills vs Rod Mills. Previous Next ... How do you decide between using a ball mill or a rod mill? Many investigators have attributed the selective grinding of rods to line contact. Other things should be considered. In the two pairs of tests shown in table 12 the relative deportment of large balls and small rods in batch wet grinding is shown.
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.
What is the difference between the ball mill and rod mill? I'm just not sure that you will believe this leap of logic. A ball mill contains balls. A rod mill contains rods.
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.

Ball mills. Ball mill (Fig 1) is same kind of mill as rod mill, except that it is filled with balls instead of rods. Because of balls have greater ratio of surface area than rods they are more suitable for fine grinding. Balls are also lighter, so the kinetic energy of a single dropping ball is smaller than a rod.
The obvious difference between the two is the grinding medium. Rod mill is named for the medium of the steel rod. The latter's grinding medium is undoubtedly a steel ball. Both of them can be used for grinding various metal ore and non-metal ore. In some cases, rod mill is also called rod type sand making machine, which is mostly used for ...
The difference between ball mill and rod mill . 1. Shape and structure. The ratio of tube length to diameter of the rod mill is generally 1.5-2.0, and the inner surface of the lining plate on the end cover is vertical plane. The ratio of cylinder length to diameter of ball mill is small, and in most cases the ratio is only slightly greater than 1.
The ball mill can also be made into a conical roller. So what are Specific differences between ball mill and rod mill? Specific expression is as follows: 1. The ball mill and rod mill is mainly used for grinding the size of not more than 60mm of various hardness of ore and other materials used.
May 03, 2017· First, the advantages of ball mill 1, ball mill for a variety of materials can adapt to continuous production, production capacity, to meet the needs of large-scale production. 2, ball mill crushing relatively large, easy to adjust the thickness o...
