A grinding mill is a unit operation designed to break a solid material into smaller pieces. There are many different types of grinding mills and many types of materials processed in them. Historically mills were powered by hand (mortar and pestle), working animal (horse mill), wind (windmill) or water (watermill). Today they are also powered by electricity. But do you know the relationship and difference between rod mill and ball mill machine?Rod mill is also called rod grinding rod mill, bar mill and rod grinding mill. Our rod grinder is especially suitable for crushing river gravel to make sand. It"s a kind of effective and energy saving rod grinding machine. Moreover, according to different materials and discharging methods, there are dry rod mills and wet type rod mills for choice. We can make the rod mill according to the different commendation of the customers, whose satisfaction can be our great honor in the process of production. Today let us have the honor to introduce the basic information to the people looking for it.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. 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 mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm. Grinding action is by line contact between the rods extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers. This results in preferential grinding of coarse material and minimizes production of slimes.If you have any other question or have an...
