Sales OnlineNov 19, 2019· The rod mill adopts overflow type and open type discharge, does not use grate type discharge The diameter of the rod mill discharge end is larger than that of the same size ball mill When the rod mill speed is lower than the working speed of the same size ball mill, the medium in the rod mill ,

Sales OnlineThe 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

Sales OnlineJun 19, 2015· Here a Rod Mill has its daily 35" steel rods being added using a mechanised rod mill charger The operator only has a few minutes to load the rods and rest,

Sales OnlineA 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 wet-grinding rod mill-ball mill circuit Rod mills came into use in the United States beginning in 1900s and ,

Sales OnlineWhen the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length New feed entering at one end of the mill causes the rod charge to spread at that end This produces a series of wedge shaped slots tapering toward the discharge end The tumbling and rolling rods expend most of their crushing force on the ,

Sales OnlineThe invention discloses a sand mill which comprises a sanding part A sanding operation head comprises a connection rod in linear reciprocation and a movement conversion mechanism connected with the connection rod, and the movement conversion mechanism converts linear reciprocating movement of the connection rod into movement that the sanding part moves around a preset axis

Sales OnlineOleg D Neikov, in Handbook of Non-Ferrous Metal Powders, 2009 Tumbling Ball Mills Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale Grinding elements in ball mills travel at different velociti Therefore, collision force, direction and kinetic energy between two or more elements vary ,

Sales OnlineAt least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 21 mm whereas Ball Mill Work Index (BWI) is used for the range from 21 mm down to 100 µm

Sales OnlineRod mill Unlike the ball mill, the grinding medium in the rod mill is a steel rod, so the working characteristics are significantly different from those of the ball mill Since the steel balls are in point contact, the steel rods are in line contact When the steel rods are sandwiched between the steel rods, the coarse particles are first ,

Sales OnlineJan 01, 2016· For a rod mill–ball mill circuit, do not apply a mill diameter correction for the ball mill If the rod mill feed is produced by open circuit crushing, use a factor of 12 for the rod mill stage only If the rod mill feed is 80% passing 12 mm or less (eg from a closed circuit crusher) do not apply a rod mill efficiency factor

Sales OnlineBall Mill Operation Ball mills ride on steel tires or supported on both ends by trunnions Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive The prime movers are usually synchronized motors During rotation, a portion of the charge is lifted along the inside perimeter

Sales OnlineRod mill and ball mill are both used to grind ore, and be chosen according to the different working condition Generally speaking, different contact mode determines different grinding granularity Rod mill is applied for coarse grinding for the reason that its media is steel rod and is liner contact, while ball mill is applied for fine grinding for the reason that its media is steel ball and ,

Sales OnlineThe rod mill adopts overflow type and open type discharge, does not use grate type discharge the diameter of the rod mill discharge end is larger than that of the same size ball mill when the rod mill speed is lower than the working speed of the same size ball mill, the medium in the rod mill is in a sloping working state
