In this post, we're going to learn more about rod mill. We'll cover it from two aspects: 1. Working principle. 2. Structure. Let's dive right in! 1. Working Principle of Rod Mill. Rod mill is a common equipment for grinding operation in mineral concentrator, which is mainly suitable for rough grinding operation.
اقرأ أكثرThe rod mill, a tumbling mill characterized by the use of rods as grinding media, grinds ores, coal/ coke, and other materials for both wet and dry ap-plications. The rod mill accepts feed ore as coarse as 1 1/2" top size although better performance is obtained by restricting ore feed size to 3/4".

اقرأ أكثرThe rod mill motor power is in horsepower at the mill pinion-shaft. For different length rod mills power varies directly as rod length. For difference between new and worn liners increase power draw by 6%, and adjust for bulk density per Table A. Wet grinding rod mills are normally used in minerals processing plants.
اقرأ أكثرThe Rod Mill is the same as the Ball Mill in the construction and available to both of wet and dry processing. Unlike the Ball Mill, however, the Rod Mill uses rods instead of balls as the grinding medium. As a result, its uses are different from those with the Ball Mill. In other words, the Rod Mill gives impact on and grinds coarse particles ...
اقرأ أكثرBecause 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.
