Apr 09, 2015 Ball mills. Ball mill (Fig 1) is same kind of mill as rod mill, except that it is filled with balls instead of rods. Because of balls have greater ratio of surface area than rods they are suitable for fine grinding. Balls are also lighter, so the kinetic energy of a single dropping ball is smaller than a rod.In addition, the cylinder speed of the rod mill is lower than that of the ball mill, so the grinding medium works in the cascading state. 2. Discharging way of ball mill and rod mill. The ball mill is commonly divided into grid type ball mill and overflow type ball mill (named by the different discharging structure).
Gearless mill drive (GMD) technology has further expanded the use of large SAG milling allowing Metso Outotec to produce the world's largest SAG mill of 42’ in diameter drawing power at 28 MW.

Though used different medium (steel ball and steel rod are contained in ball mill and rod mill), the working theory of ball mill and rod mill are similar.Attrition mill is a type of grinding mill by kinds of media to crush lump to powder like substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10 ), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.
This ball mill and rod mill power draw model is based on a torque model and empirical measurements made by the Nordberg Equipment Company for use by its sales representatives to size grinding mills. Slight differences in the equations used allow rod mills, dry ball mills and wet overflow and grate ball mills to be sized.The 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.
Supported grinding mills up to the largest sizes. SAG ball mill circuit incorporating pebble crushers and a POLYCOM high pressure grinding roll. SAG and ball mill for gold ore grinding. One of three SAG mills with 9.75 m diameter and 2 x 4000 kW drive power. These mills operate in conjunction with ball mills for iron ore grinding in Iran.Jan 27, 2020 Figure 1 Sliding abrasion action in a Ball Mill. Figure 2 Cascading impact action in a SAG mill. Rubber and composite mill lining systems. In the past, grinding mills were typically lined with cast metal linings of varying steel or iron alloys, and lining system selection was typically driven by level of wear protection and cost.
Recommendation of ball mill and rod mill Ball mill and rod mill are suitable for different materials 1. 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.Sep 09, 2019 In the ball mill, commonly used have the lattice ball mill and overflow ball mill (named from different drainage structure), and the rod mill does not use the grid plate drainore, only overflow type and opening type two kinds, the diameter of the hollow shaft at the drainage and end is generally larger than the same specification ball mill.
Search rod mill power vs ball mill to find your need. kefid Mining and Construction Machinery is a global manufacturer and supplier, We supply full crushing and Rod mills, how they function – Mine Engineer.Com provides.Apr 02, 2012 Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
Dec 12, 2016 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.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.
Rod mill , as the name suggests, is to rely on rod bars for the material grinding,and wet overflow is a generally used material way.Rod mill is generally used as a grinding equipment in the artificial stone sand, concentrator, chemical plants and power sectors.
