The rod mill can grind a variety of fine powders, which is also a fine particle size, which is also a wide range in the mine field. By observing its structure, it can notice its ventilation section, from the literal meaning. There is a relationship with ventilation. What is the role of its ventilation?
1, when the bar is hitting the ore, first is shattered the coarse grain, and then grind smaller mineral particles; between the rods and the rod contact, and between the ball and the ball are in contact, therefore, when When the rod mill rises along the barrel, there is a coarse grain, a rod sieve effect, so that the fine particles are passed from the rod, and the material forms natural accumulation in the bottom surface of the tube, so that the feed port is effective in ventilation area, quite One-third of the design of ventilation is designed.
2, the material is in the process of grinding, the water vapor and fine powder evaporated in time cannot be discharged in time, so that the impact of the steel ball is weakened, resulting in a gradually bonding of the micro powder in the front cylinder corner portion, forming a severe paste. Grinding.
3, if the rod mill is ventilated, then the heat generated during the grinding cannot be discharged in time, and the temperature in the grinding is increased. The temperature increases the surface of the cement micro-fine particles on the surface of the cement micro-fine particles, and the particles are coaleshed between the particles and the grinding body under the action of electrostatic electricity, resulting in an electrostatic adsorption of the abrasive body.
These are rod mill ventilation and cross-sectional effects, it can be seen that it can play a critical role in the timely discharge of excess impurities, and promoting ventilation, reducing fever can play a key role, so we cannot ignore the role of ventilation.
