Jul 03, 2017 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 in place approximately 300 pounds per cu. ft..

Sepors 16 x 32 continuous ball or rod mill is ideal for pilot plant studies of ore grinding and processing or just regular small scale grinding requirements you may have. The mill can be used in a closed circuit, with a spiral classifier, screen or cyclones or as a single pass grinding mill.
The structure of the rod mill is the same as the ball mill. The main difference is that the grinding media inside the rod mill is steel rods, while the ball mill adopts steel ball as the grinding media. Besides, the rod mill does not use grate plates for material discharging but applies open type, overflow type, or peripheral type discharge device.
Typically R 8. Rod Mill Charge Typically 45% of internal volume 35% 65% range. Bed porosity typically 40%. Height of bed measured in the same way as ball mills. Bulk density of rods 6.25 tons/m3.

Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher. Secondary grinders are fed from other grinders e.g. a rod mill. Ball mills are usually either of the grate (diaphragm) or overflow type.
Apr 07, 2016 Rod mill are used widely in plant and are compared by us. This text will analyze the two equipment in some aspect. The grinding theory. 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.
Rod mill has a wide application range, especially when grinding in some special conditions 1. To avoid the damages caused by over-crushing, gravity separation plant or magnetic separation plant for tungsten-tin ore and other rare metal ore always uses rod mill. 2. In some cases, rod mill can perform crushing instead of short head cone crusher.
At present, rod mill is the most effective crushing machine and its performance has achieved the international standard. It is widely applied in the gravel industry. And it is mainly used for processing or crushing the feldspar, quartz, minerals and other raw materials, and it is also suitable for finely or secondarily crushing the various tough or brittle materials, such as grinding material ...

Specifications Laboratory Scale Rod Mill is a efficient lab grinding equipment for wet or dry grinding of mineral ores. It is widely used in labs for processing and fine grinding of artificial placer materials and ores in metallurgical, building material, chemical, light, coal, water conservancy, electric power, agricultural and geological industries.
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 rod mill uses the steel rod with a diameter of 50-100mm as the grinding medium, while the ball mill uses the steel ball most. Moreover, the diameter of the hollow shaft neck is larger than that of the same size ball mill. 3. Application fields. In the two-stage grinding process, the rod mill is generally used as the first section of the ...
No 1 rod mill/ball mill circuit was operating very ef ciently when comparing the combined operating work indices for both mills with the rod mill and ball mill laboratory work indices. Note, in Figure. 1, that the rod mill product slope is less than 0.5 due to an extra amount of
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.
Ball Mills are primarily used for fine grinding. Ball Mill is key equipment which repulverises the material after it is crushed. Ball Mill is widely used in powder-making production line including cement, silicate, new-type building material
