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 [5]

Jean-Paul Duroudier, in Size Reduction of Divided Solids, 2016. 3.7.4 Performance. 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.

The Mill speed and dynamics depends on the rotating machine which is the Drive motor. The Mill stands need to be operated with variable linear speeds depending on the reduction ratio between each stand and varies with the bar size to be rolled. AC or DC DRIVE With the advent of vector cotrolled AC Inverters the use of AC Motors in the Mills has

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.

Dependent upon the Material and the Process! I seen feed as large as 100mm on soft material. There are specialty rod mills where you target a low ratio of reduction such as end and center peripheral discharge than feed need to be targeted to product size required based upon the calculate reduction ratio in the rod mill.

Springs are produced from medium or high carbon steels with a very high yield strength obtained by heat treatment after processing. Yield strength is the essential property of the elastic behaviour of the spring as it allows the part formed with these grades to return to its original shape after signiﬁcant bending or twisting.

Friction reduction ratio is the function of the average velocity of fracturing fluid, the gelled agent concentration, and the proppant concentration. Based on the linear regression of 1049 experimental and field data, Lord et al. put forward the following empirical formula to calculate the friction reduction ratio of HPG fracturing fluid (Lord, 1987):

Reduction ratio - an overview sciencedirect topics the reduction ratio r in rod mills varies from 2 and 20 depending on the characteristics of the orethe usual reduction ratio is about 8 according to bond 4 the reduction ratio is a function of.

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. Sie Reduction With Planetary ...

Ball mills are usually designed with a maximum reduction factor/ratio of 60:1 although it is possible to achieve reduction ratios of up to 70:1. The electric drive for a ball mill should be able to handle loads where the ball mill is charged by up to 45% with balls.

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 3000 to 270 mm (–4 to –35 mesh). Grinding action is by line contact between the rods extending the length of the mill.

A: Forging reduction is generally considered to be the amount of cross-sectional reduction taking place during drawing out of a bar or billet. The original cross-section divided by the final cross-section is the forging ratio (say 3:1). There is an equivalent reduction on upsetting for forgings being upset during forging (gear blanks, for example).
