pulverizer mills basic design

The three fundamental designsused in the construction of pulverizer mills are contact, ball, andimpact mills. Each of these designs attempts to meet certainrequirements that are necessary for a good pulverizer design:

  1. Optimal fineness fo design coals over the operating load range of the pulverizer

  2. Rapid response to load changes

  3. Safe operation over load range

  4. Reliable operation

  5. Low maintenance, particularly in grinding elements

  6. Capable of handling a variety of coals

  7. Ease of maintenance

  8. Minimum space requirements


The principle of pulverizer
Using high-speed airflowblades cutting and impact of the collision pulverized a doublefeature on one, and can also complete the separation of particulateprocessing. pulverizing the blade cutting process, a high-speedairflow with the rotor blade cutting the direction of rotation, theflow of materials to accelerate and impact of the materials at thesame time repeatedly subject to double smash, pulverize theaccelerated rate of the materials. The material was pulverized withthe airflow into the grading room, because the classification rotorhigh-speed rotation, both particles generated by the rotor of theclassification of centrifugal force, generated by the centripetalforce of viscous flow, when the particles larger than centripetalforce by the centrifugal force, both Rough grading on the trail toreturn to smash particles to smash the room below grade track fineparticles into the air with the powder set for the collection, gasfrom the wind, scattered dust from the mouth automatically, is a newcombination of equipment, their performance is better than the airgrinder And mechanical shredders, can replace imported equipment.With low energy consumption and small footprint process short, nodust pollution, produce heat small, refined small size, to crush awide range of materials is not limited moisture, feed size limitationand soon
