Rod Mill is different with Ball Mill. 1. Grinding media of Rod mill are steel bars. ball mill use of steel balls as grinding media. 2. Rod mill is suitable for coarse grinding, when product granularity is between 1 to 3mm, processing capacity of rod mill is bigger than ball mill with same specification. 3.
convert less power per mill volume unit than rod and ball mills. High quality steel rods and balls are a considerable part of the operating costs. Autogenous grinding should, therefore, be considered and tested when a new plant shall be designed. As a grinding mill is built to last for decades, it is more important

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 batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.
Pebble mills should always be of the grate discharge type. The energy that can be converted in a mill depends on the total weight of the grinding charge. Consequently, pebble mills convert less power per mill volume unit than rod and ball mills. High quality steel rods …

Ball & Rod Mill. Enquire Ball mills and rod mills provide an effective means for grinding and blending materials in preparation for mineral liberation, from rock to dust. These grinding mills may be necessary for improved gold and mineral recoveries. Both ball and rod mills have a hollow cylindrical shell that rotates about an axis.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Overview. The ball mill for clinker is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores.

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 mill and ball mill are both used to grind ore, and be chosen according to the different working condition. Generally speaking, different contact mode determines different grinding granularity. Rod mill is applied for coarse grinding for the reason that its media is steel rod and is liner contact, while ball mill is applied for fine grinding for the reason that its media is steel ball and ...
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
