M Grinding Rod Mill

31/05/2016· The grinding action of a rod mill is line contact. As material travels from the feed end to the discharge end it is subjected to crushing forces inflicted

20/02/2017· Rod mills are used for primary grinding of materials with a top size of 20-30 mm (somewhat higher for soft materials). The production of fines is low and consequently a rod mill is the right machine when a steep particle size distribution curve is desired. A product with 80% minus 500 microns can be obtained in an economical manner.

Rod mills are used in an open circuit between crushing and the ball 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. As such, when the product is sticky, rod mills are preferred over ball mills.

A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action. An ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into finer particles. Although similar in operation, a rod mill is often more effective than a ball mill as it requires lower

Rod mill is a grinding equipment with steel rod as grinding medium. It is used to coarse grinding and suitable for fine crushing and coarse grinding in first stage of open circuit grinding. This machine include overflow rod mill, end peripheral discharge rod mill and center peripheral discharge rod mill, which could meet different requirement. Features and technology

08/03/2021· Rod mill is suitable for grinding brittle material, such as rare metals. 2. Selection by required particle size The steel ball of ball mill and the mineral material are in point contact, so the finished product has a high degree of fineness, but it is also prone to over-grinding. Therefore, it is suitable for the production with high material fineness and is not suitable for the gravity,

Grinding medium The grinding medium of rod mill is steel rod which is recognized that the length of rod is less than 7m because the large length is easy to twine. The diameter of rod is 75~150mm Grinding rod should have enough stiffness and hardness to keep straight, and it should not be too crisp which causes the rod broke into pieces without enough wear.

Rod Mill, is a grinding machine similar to a ball mill. The obvious difference between the two is the grinding medium. Rod mill is named after the medium is a 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 case, rod mill is also called rod type sand making machine, which is

29/11/2018· 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. There is point-to-point contact between the ball mill with the steel ball,

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 particles of media - the rods, balls

This test also shows that by feeding the mill with a too dilute pulp, the grinding zones between the media are not saturated, leading to high media wear rate. A variation in total ball angle can be detected and linked to grinding efficiency and charge expansion. This could help the operator to make the right decision and keep the mill running in such a way as to be close to the optimum
