What Are The Differences Between Ball Mill And Rod Mill

recommendation of ball mill and rod mill ball mill and rod mill are suitable for different materials selection by materials hardness ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. rod mill is suitable for grinding brittle material, such as rare metals.nov 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 is in a sloping working state.ball mill and rod mill are the common grinding equipment widely used in the mineral processing plant. they are similar in shape and grinding principle, but also different in structure, performance and application. here are seven differences between ball mill and rod mill to tell you how to choose the ball mill and rod mill.ballrod mill literature the ballrod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. they are the most effective laboratory mills for batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.

Ball Mill Savree

ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. ball mills may be primary or secondary grinders. primary grinders are fed from crushers such as a jaw crusher. secondary grinders are fed from other grinders e.g. a rod mill. ball mills are usually either of the grate or overflow type.ball mill is the key equipment for grinding materials. those grinding mills are widely used in the mining process, and it has a wide range of usage in grinding mineral or material into fine powder, such as gold, ironzinc ore, copper, etc.. jxsc mining produce reliable effective ball mill for long life and minimum maintenance, incorporate many of the qualities which have made us being herein, a versatile approach is demonstrated to skilfully synthesize Co nanoparticles encapsulated in nitrogen doped hollow carbon rods by ball-milling following simple heat treatment.

Calculating Steel Ball Charge In Ball Mill

rod mills are very similar to ball mills, except they use long rods for grinding media. To prevent the conditions leading to rod charge tangling, the length to for an equivalent grind, a rod mill uses less steel than a ball mill because of therod mill introduction the hongxing rod mill manufacturer adopts advanced controllable feeding and discharging technology, combined with the actual grinding material, with the appropriate grinding body, and the traditional surface contact is changed into line contact so that the discharge granularity is more uniform and the output is higher.rod mill is a type of grinding mill whose grinding media is steel bar, while ball mill is steel ball. rod mill are usually applied to grinding the w-sn ore and rare metal in the reselection or magneticore-dressing plant in order to avoid the damage caused by the over crushing.
