Differences between ball mill and rod mill Different in performance Ball mill It can be divided into two types of ball mills according to the discharging ways, overflow discharge ball mill, and grate discharge ball mill. FTM ball mill Grate discharge ball mill.
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.
When 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
The difference between ball mill and rod mill . 1. Shape and structure. The ratio of tube length to diameter of the rod mill is generally 1.5-2.0, and the inner surface of the lining plate on the end cover is vertical plane. The ratio of cylinder length to diameter of ball mill is small, and in most cases the ratio is only slightly greater than 1.

Ball mill and rod mill are used in wet and dry processes to deal with various hardness of ore, rock and other materials. So what are the differences between ball mill and rod mill? 1. Ball mill and rod mill are used to deal with various hardness of ore, rock and other materials whose particle size is
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.Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of
Comparison between Rod Mill and Ball Mill. 20140103. 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 wsn ore and rare metal in the reselection or magneticoredressing plant in order to avoid the damage caused by the over crushing. Get price
Bauxite grindability at elevated temperature in various mills. This difference between Bond Rod mill and Ball mill or Hardgrove mill curve slopes is presumably due to the coarser feed particle size of the Rod mill experiments (X 80 = 2.3 mm X max = 7 mm) unlike Bond ball mill feed size (X 80 = 2 mm X max = 3.15 mm).
11-06-2019· The material to be ground is fed between the rollers and is nipped crushed by pressure tension, versus the crushing abrasion of the ball/rod mills. The roll mill can also be operted wet or dry. Also, in between the grinding capabilities of the ball and roll mills, there are hammer, chain, cage, impact and air mills, all capable of medium to fine grinding, depending on the feed material.

Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones. This is generally followed by a cone crusher. A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
