rod mills with high reduction ratio

To prevent the conditions leading torodcharge tangling, the length to diameterratiois maintained at 1.4 to 1.6.Rod millsaccept 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 themill.

The Worlds Largest Copper ProducersRod millsare very similar to ballmillsexcept they use long rods for grinding media The rods grind the ore by tumbling within the themillsimilar to the grinding balls in a ballmillTo prevent the conditions leading torodcharge tangling the length to diameterratiois maintained at 14 to 16 Thereduction ratioof a crushing stage can be defined as the ...

Jean-Paul Duroudier, in SizeReductionof Divided Solids, 2016. 3.7.4 Performance.Rod millsare used in an open circuit between crushing and the ballmill. 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 reduction ratio, R, in rod mills varies from 2 and 20 depending on the characteristics of the ore.The usual reduction ratio is about8. According to Bond, the reduction ratio is a function of length and diameter of the mill. The optimum reduction ratio, R RO, can be written as AMIT 135: Lesson 8 Rod Mills – Mining Mill Operator Training

Themillproduct can either be finished size ready for processing, or an intermediate size ready for final grinding in arod mill, ballmillor pebblemill. AG/SAGmillscan accomplish the same sizereductionwork as two or three stages of crushing and screening, arod mill, and some or all of the work of a ballmill.

Rod mills with high reduction ratio. India Crowdme Large Mining Machinery Co., Ltd are a large-scale joint-stock enterprise integrating R & D, production, sales and service. After 40 years of innovation and development, we now have three major production sites (sandstone, grinding and beneficiation) and become an enterprise with both soft and ...

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