Ball/Rod mill Literature . The Ball/Rod 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 batchwise, rapid grinding of mediumhard to very hard samples down to finest particle sizes.

Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.
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.
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.
The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming effects. These ball mills are also suitable for mechano chemistry.

This means that the number of crushing stages can be reduced depending on the feed size accepted by primary grinding stage.

Depending on the hardness of the feed material, the typical maximum feed size is between 5 and 10 mm but in special cases it may be up to 20 mm. If the mill is operated in closed circuit, the product fineness will be between 20 µm and 250 µm, while an open circuit mill .

Rod Mill Operations. Designed to accept feed from a secondary crusher. Feed particle size = 6 – 25 mm. Peripheral speed = 85 146 m/min (280 – 480ft/m in) Reduction ratio = 2 – 20 depending on material. Typically R = 8. Rod Mill Charge: Typically 45% of internal volume; 35% – 65% range; Bed porosity typically 40%.
Rod mills have become niche comminution devices since about 30 years ago. Because of mechanical limitations on rod length and the need to have an aspect ratio for the mill that avoids tangling (a potentially deadly failure for those tasked with rectifying the problem) rod mills have a maximum installed power of about MW.

Every mining operation has a unique grinding process. has experience of over 8,000 grinding mills globally, including manufacturing and delivering the largest SAG/AG mills in the world. Our experts welcome the opportunity to assist you with circuit and circuit control design as well as startup, operation, and optimization of your mill.
Please note: *depending on feed material and instrument configuration/settings Function Principle The grinding jars of the mixer mill MM 500 perform radial oscillations in a horizontal position. The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the grinding jars and pulverize it.
Furthermore, you are able to minimize the feed ball size to achieve higher degree of efficiency of ball grinding, which is exceedingly useful for a large amount of grinding. This type of rod mills normally feeds balls of less than 15 to 30 mm in diameter to produce 80% product size 500 to 1000m.
A shell length above 6100 mm can not be recommended. As the length to diameter ratio of the mill should be in the range of 1,21,5, the biggest rod mill will convert maximum 1500 kW. Rod mills are used for primary grinding of materials with a top size of 2030 mm (somewhat higher for soft materials).
