2017-7-3 Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls

2021-3-8 Recommendation of ball mill and rod mill Ball mill and rod mill are suitable for different materials 1. Selection by material's 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.

2016-4-7 For ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral. Thus, the throwing motion of ball can produce a large impact, but it need a high rotate speed and has a higher power consumption. But for rod mill, grinding effect is better which need a lower rotate speed

2014-1-3 Rod mill is a type of grinding mill whose grinding media is steel bar, while ball mill is steel ball. 1. 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. 2. In the two stage grinding process, if it requires grinding the ore from 20-6mm to 1-3mm in the first stage, rod

2016-12-12 The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).

2009-7-30 mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential

Though ball mills are used more often rod mills can be the better option for specific mining ores and larger site projects. In a ball mill the actual balls in the machine need to cascade in order for the grinding to be accomplished. Because of this more energy is needed to power up a ball press as opposed to a rod

It accounts for up to 40% of the total power consumption in mineral processing plant operations. So, selecting the efficient solution for grinding section is very important. Prominer provides ball mill / rod mill grinding system which is widely used in various types of ores' beneficiation, electricity, cement and chemical industries.

1. Ball Mill: The grinding medium is mainly short steel bar or steel ball.The grinding force of ball mill is large, the structure is light, and the rotation speed is stable. 2. Rod Mill: The grinding medium is mainly steel rod, the diameter of steel rod is mostly between 50-100mm, and the grinding time is longer.. 3. Gravel Mill: The grinding medium mainly includes pebble, gravel, sand

2017-10-12 Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes. Various kinds of mills are there with which different material processing takes place.

Ball mill for sale In all the ore mining beneficiation and concentrating processes, including gravity separation, chemical, froth flotation, the working principle is to prepare fine size ores by crushing and grinding often with rock crushers, rod mill, and ball mils for the subsequent treatment.

2014-10-1 conventional crushing and grinding circuits (crusher-rod-ball mill or crusher-ball mill). By the 1970s, the application of conventional tended to be limited to relatively low capacities. circuits The majority of modern grinding circuits include a SAG mill, a ball mill and/or a
