7 major differences between ball mill and rod mill,the rod mill usually uses the steel rod with a diameter of as the grinding medium, while the ball mill usually uses the steel ball as the grinding medium. the steel balls of ball mill are in point contact, while the steel rods of rod mill are in linear contact, so
We provide quality and efficient solutions to our global customers
the rod mill usually uses the steel rod with a diameter of as the grinding medium, while the ball mill usually uses the steel ball as the grinding medium. the steel balls of ball mill are in point contact, while the steel rods of rod mill are in linear contact, so It is better to choose a grate discharge ball mill is different: the cylinder of the rod mill is a long type, and the floor rod mill is suitable for grinding brittle material, such as rare metals. than the diameter of the feeding port about to centimeters, so that the height processes that require the production of medium-sized products.feed size should generally be -18, for ball mill and -12 for rod mill. they are of a sturdy, rugged design to handle frequent use with hard materials. the batch ball and rod mills require a drive roll to rotate the mills. the batch ball mill should be run between rpm and rpm. the batch rod mill should be run between rpm and rpm.
Get Detailsdec 30, 2012 would suggest that you build a rod mill if you want to get the material down to a fine power, a ball mill usually is used to make bigger item smaller, e.g. big rocks down to little rocks, and then the material goes into a rod mills to take it down to a powder.introduction. the rod mill is loaded with the grinding media of steel bars. It consists of five parts including cylinder shell, feeding system, discharge system, main bearing and transmission system. It is available for both of the dry grinding and wet grinding fashion as the customers needs.jan 01, 2016 these corrections apply both for ball mill and rod mill grinding. correction factors suggested by rowland and kjos that apply for ball mills are given below. correction for dry grinding, as bonds
Get Detailsthe work index calculated from the testing can be used in the design and analysis of ball mill circuits. the test requires a minimum of of sample that has been stage-crushed to 100% passing size of 3.35 mm. any screen size below can be used for the testwork depending on your requirements. bond rod mill grindability testcolumbia international ball mills for fine grinding chemical reactors ball mills for fine grinding furnaces drying ovens centrifuges stirrer & mixers metal ware vacuum equipments automation & controllers hoods and glove boxes microscopes evaporation & distillation spray dryers pressing machine and dies voltage transformers liquid nitrogen tanks filtration ultrasonicators freeze dryer steel steel billets, bars, and rods: billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster, they are rolled from blooms by billet mills. one method of rolling billets, which are usually to 125 millimetres square, is to use a three-high mill with box passes, as shown in in the figure.

Get Detailsrod 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.ball mills mineral processing & metallurgy. ball VS rod mill conversion. the correct grinding mill depends so much upon the particular ore being treated and the product desired, that a mill must have maximum flexibility in length, type of grinding medium, type of discharge, and speed.Hi there, We have a wet overflow rod mill which is being used to grind malachite. We want to convert it into ball mill to get the finer product 80% passing micron. can we do the same? simply, can we convert rod mill to ball mill? if yes then what are the measures we should consider.
Get Detailsthe 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.rods are placed parallel along the length of the rod mill. rods are shorter than the mill length. breakage occurs more from cascading than cateracting. the product size distribution is narrower than a ball mill but significantly coarser. most are overflow discharge type. length-to-diameter 1.4 to 2.3. mill length meters. rod mill recommendation of ball mill and rod mill ball mill and rod mill are suitable for different materials the daily maintenance requires constant addition of a certain amount of steel balls, while the rod mill only needs to be inspected and replaced in a period of time.the product of the rod mill is rough, but the particle size is uniform, coarse particles and slime are less, the over
