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 semiautogenous. 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
4WhatsAppThe types of mills are distinguished by their working principles: by pressure, impact, hammer, or shear. Mills could be equipped with a screen for grain size control and separation. The FAM product range includes impact mills, roller mills, hammer mills, ball mills and rod mills
WhatsApp(1) Rod mill is usually selected in order to prevent over grinding in gravity or magnetic separation plant of tungsten tin and other rare metals mine; (2) In two stages grinding, the capacity of rod mill machine used in the first stage grinding is larger than ball mill''s; (3) In some cases, rod mill
WhatsAppThe ball and the rod mill are of essentially the same basic concept comprising a barrel mounted in a rotating yoke assembly, which is driven through a gearbox from a three phase electric motor. The barrel is pivot mounted on the rotating yoke and can be tilted for loading and discharge. A spring loaded locking pin is used to hold the barrel in its horizontal operating position. A manually

WhatsApp· Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill. The action of other grinding
4WhatsAppA rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill. The principal use for rod mills, which were invented to make ball mill feed in a wetgrinding rod millball mill circuit.
WhatsAppBall mills with a drum length to diameter ratio greater than are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher. Secondary grinders are fed from other grinders a rod mill. Ball mills are usually either of the grate (diaphragm) or overflow type.
WhatsAppTo liberate minerals from sparsely distributed and depleting the ore bodies finer grinding than generally obtained by the conventional Rod Mill –Ball Mill grinding circuits is needed. Longer grinding periods in the conventional milling processes prove too expensive mainly due to large power consumption. Stirrer mills have been tried in mineral industry with considerable success and have
WhatsAppuse of rod mill in mineral processingwiebkewoetzel . use of rod mills in mineral processing. Rod Mills Metallurgist Mineral Processing Engineer A rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill.
WhatsAppRod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon 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
WhatsAppThe 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 to Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
WhatsApp· The rod mill is a grinding machine with steel rod as grinding medium, mainly used for rough grinding operation. It is generally used as wet overflow type and can be used as onestage open grinding.
