1. What is the grinding effect of the rod mill?
The grinding force of the rod mill relies on the pressure of the rod and the grinding force to grind the ore. When the rod hits the ore, the first is to break the coarse particles, and then grind the smaller ore; the rod is in contact with the rod, and the ball is in contact with the ball, so when the rod rotates along the barrel wall When rising, the coarse particles are sandwiched between them, similar to the action of the bars, so that the fine particles pass between the joints, and the material forms a natural accumulation on the bottom of the material to make the effective ventilation area of ​​the inlet, which is equivalent to three points of the design ventilation cross-sectional area. To one. During the grinding and heating process of the material, the water vapor and the fine powder evaporated from the material cannot be discharged in time, so that the impact force of the steel ball is weakened, and the fine powder in the corner portion of the front cylinder is gradually bonded, forming a serious grinding phenomenon of the rod mill. . Due to the poor ventilation of the rod mill, the heat generated during the grinding cannot be discharged in time, and the temperature inside the mill is increased. When the temperature is increased, the surface of the fine particles of the cement micropowder is charged, and under the action of static electricity, the particles are condensed between the particles and the particles, and the surface of the abrasive body is electrostatically adsorbed by the fine powder.
Second, what are the fields of use of rod mills?
In the entire field of grinding and crushing, there are many fields in which ball mills are used as final grinding equipment. In the type of ball mill (ball mill Hongsen classification introduced), the rod mill applications is very broad, it is mainly used in grinding artificial stone sand, mineral processing plants, chemical plants and other power sector level.
Third, the process characteristics of the rod mill?
Rod mill process features: save power, older equipment saves more than 40% of power; more uniform output size, higher output, advanced rod mill with advanced controllable inlet and outlet rod mill technology, combined with actual user grinding The material is matched with a suitable grinding body, the discharge granularity is more uniform, the output is higher; the discharge fineness is adjustable, the particle size of the discharge can be changed by simple adjustment, the fineness control device is built in, and the discharge can be screened. Device.
