Rod Mill an overview ScienceDirect Topics

In the rod mill, high carbon steel rods about 50 mm diameter and extending the whole length of the mill are used in place of balls. This mill gives a very uniform fine product and power consumption is low, although it is not suitable for very tough materials and the feed should not exceed about 25 mm in size. It is particularly useful with sticky materials which would hold the balls together in aggregates, because

Rod mills, how they function Mine Engineer.Com

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). Grinding action is by line contact between the rods extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers.

What's the Final Product? And Size? Bar and Wire Rod

The Bar and Wire Rod Mill production line's final product can be wire rod and rebar.The size of the wire rod can be 5.5-16mm, rebar can be 12-42 mm.

Rod Mills Mineral Processing & Metallurgy

Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 35-48 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.

P 80 is the mill circuit product size in micrometers; F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding

product size, 4-slit, 3-slit and 2-slit operation is used. Even if the design speed of the mills may be higher, these mills run at rolling speeds ranging in most cas-es 13 to 18 meters per second. The reason for such low speeds is the fact that operation is sensitive at small sizes and mill setting requires fine accuracy. In this regard, the experience of the rolling crew plays a key role. The

If the rod mill fi nes are taken into account the rod mill product can be theoretically corrected to show a P80 of 1700 μm, the plotted 80 per cent passing size divided by 1.7. It should be remembered, Rowland and Kjos (1978), stated that if a rod mill is operating alone, an ineffi ciency factor of 1.2 should be added provided the mill feed is screen undersize. If the rod mill feed is

L.

Thus the product from a ball mill will be a mixture of the products from these different kinds of comminution events. and may even contain un-touched feed.(2,4) On the other hand, in a rod mill the rods are wedged apart by the largest particles and there is little chance of finer particles being ground until the coarse particles have been broken. Thus, in the rod mill the kinds of comminution

Understanding Rolling Process in Long Product Rolling

A wire rod rolling mill, for example, gradually reduces the cross-sectional area of a starting billet (e.g., 150 mm square, 10-12 meters long) down to a finished rod (as small as 5.0 mm in diameter, 1.93 km long) at high finishing speeds (up to 120 m/sec).

The product size from a rod mill is much coarser. Hence a rod mill generally precedes a ball mill in a grinding circuit especially where a fine size product is required. Ball Mills: -The final stages of comminution are performed in tumbling mills using steel balls as the grinding medium and so designated "ball mills." Since balls have a greater surface area per unit weight than rods, they are

Practical 1 : Ball Milling TF Lab 1

23/12/2013 In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball
