The average particle is subjected to an action similar to many sets of rolls in series, before it is discharged. 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.

Grind coarse feed material with a reliable Rod Mill that won39t overgrind. If you are in need of an application for coarse materials like limestone, potash, coal, phosphate and bauxite, you may be looking for a solutions like Rod Mills. Rod Mills are particularly useful, if you run a low tonnage operation and are looking for coarse product.

Ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and particles. However, many customers are confused when they choosing equipments for grinding due to their similar appearance. This paragraph is a brief explanation to the difference of ball mill and rod mill below. The calling name of ball mill and rod mill comes from the different grinding medium.
Quinn offers laboratory batch rod and ball mill grinding units normally used for feed preparation in mineral, chemical, and industrial laboratories. Such preparation can be on a wet or dry basis. The charge range for the rod mill is 500 to 2000 grams and the ball mill 500 to 1500 grams based on 2.7 specific gravity material.

First, the advantages of ball mill 1, ball mill for a variety of materials can adapt to continuous production, production capacity, to meet the needs of largescale production. 2, ball mill crushing relatively large, easy to adjust the thickness o
As such, when the product is sticky, rod mills are preferred over ball mills. Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30 of the power used in a ball mill.
