The optimum number of grinding balls is 285. However, the ball diameters vary due to wear. Therefore, the total ball number should be adjusted from time to time to ensure a total mass of grams. The grinding jar of the Bond Index Ball Mill measures 12″ x 12″ and has wellrounded corners. Module Rod Mill
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50% of the mill volume and its size depends on the feed and mill size.
This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.
Best way to determine the balltopowder ratio in ballmilling? ... Total weight of ball = number of ball X weight of single ball. ... The maximum power draw in ball mill is when ball bed is 3540 ...
Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.

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 particlesize measurement device and sizecontrol cyclones.
The types of Rod Mill discharge trunnions are: overflow, perforated overflow, return spiral, grate, and peripheral. Thus the engineer can fit any one of fifteen variations of sizes and type of discharging a rod mill, into the problem on which he is working. The superiority of the Steel Head Rod Mill is due to the allsteel construction.
Grinding mills spare parts. Your mill is at the heart of your production process. When a part fails, you need to make the right decision to get your plant up and running. provides grinding mill parts for equipment previously sold under a variety of trade names and has OEM parts to fit seamlessly with your existing mill and process.
In many grinding plants mills which have metallic or rubber liners suffer from bolt breakage. Our technicians come across broken mill bolts at many sites around the world, to the operators of the mills it is an almost normal occurrence, but if you have breaking bolts there is an underlying problem which needs to be fixed.

F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term ''rod mill'' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.

Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here.
