Now a lot of industrial equipment will have their own advantages, in the choice of industrial equipment are often similar equipment to compare, know the difference between them can be selected for the actual situation. Rod mill and ball mill belong to almost the same industrial equipment. Where is the difference between the two?
1、The grinding body works differently
The reason why it is called rod mill is because its grinding medium is steel rods, while the grinding medium of ball mill is steel balls. Due to the different shapes of the grinding body, resulting in its working mode also has its own characteristics. When the steel rods are in motion, the gap between the rods and the rods is a regular long strip, which adds the role of screening to the material again, and in the working process will bring the large particles of material to a high place, which makes the large particles of material to get a good crushing effect. So that the steel rod and material contact is line contact, steel ball and material is point contact, this is the difference between the way the grinding body work.
2、Different materials
Rod mill is suitable for brittle materials, in addition, due to the rod mill over the crushing phenomenon is less, also applies to tungsten and tin ore or other rare metal ores, usually used in re-election or magnetic separation production line, the ball mill has a wider range of applications, metal, non-metallic or stone can be used to grind ball mills.
3、Different fineness of discharged material
The fineness of ball mill is finer, usually between 0.074-0.4mm, while the fineness of rod mill is between 0.833-0.147mm.
4、Different classification
Ball mill can be divided into overflow type and lattice type, while the classification of rod mill, for overflow type rod mill and open type.
There is a difference between the rod mill and ball mill, so we must pay attention to distinguish before use, or if you use the wrong one, then the impact is also very large. Because they are not the same use. The media used is also different.
