Product introduction of rod mill:The rod mill (rod type ball mill) is also divided into two types: dry type and wet type. The world advanced controlled technology is adopted for material feeding and material discharge, and the suitable abrasive materials should be used in the actual abrasive materials. The traditional surface contact is changed to line contact, the granularity of the material is even more uniform and the output is higher. It is widely used in grinding, such as refractory, chemical, metallurgy, glass and other industries. In addition, it has also been used in the sand making industry of building sand in recent years.
Performance advantages of rod mill:1. The rod mill ball mill saves power. Compared with the traditional equipment, it can save more than 45% of the power. It has the advantages of economic reliability and comprehensive benefits.
2, the machine powder particles are more uniform, the coarse particles are less, the fineness index of raw material can be relaxed properly; compared with the traditional equipment, the output is about 25%, the unit power consumption is about 26%, and the attrition of the grinding body is less.
3. The rod mill has a compact structure and a strong machine; and the machine has advanced technology, adding the moment of inertia of the whole machine, so that the equipment has the advantages of strong impact resistance, abrasion resistance and great impact force.
Working principle of rod mill:The material is grinded into the cylinder through hollow shaft neck, and various diameter grinding media are installed inside the cylinder. When the cylinder revolves around a horizontal axis at a certain speed, the medium and raw material installed in the cylinder, under the action of centrifugal force and friction, are thrown down as the cylinder reaches a certain height because of its own gravity, and the Falling Abrasive will crush the material in the barrel like the projectile. The material is made of the feeding device through the hollow shaft of the feed into the first silo of the mill. There are stepped lining or corrugated lining in the silo, with different specifications of steel ball in it. The cylinder is rotated to produce centrifugal force to drop the ball to a certain height and produce heavy blow and grinding to the material. After rough grinding, the material enters the second storehouse through a single storehouse board. It has a flat lining plate and a steel ball, which further grinds the material. The grated material is discharged through the hollow neck.
