Working Method

The material enters the grinding chamber via the funnel and spiral conveyor where it is sheared and broken by the fastrotating blades. The power passes the guide ring and enters the classification chamber. As the classification wheel is in revolution, both the air force and centrifugal force act on the powder.

As the particles whose diameters are greater than the critical diameter (diameter of the classification particles) have a great mass, they are thrown back into the grinding chamber to be ground again, while the particles whose diameters are smaller than the critical diameter enter the cyclone separator and bagtype collector via the material exit pipe be means of negative pressure wind conveyance.The discharge material meets the requirement for the product.

Working Principle

After jaw crushers break large bulky materials to smaller ones, elevators work to send materials to the hopper. Then, by electromagnetic vibrating feeders, broken materials are evenly and quantitatively sent to the grinding chamber of MTM Medium-speed Grinding Mill. After grinding, materials are blown away by airflow to the powder concentrator for classifying. Under the action of the impeller of powder selector, materials which fail to meet fineness would be sent back to grinding chamber to get another grinding while qualified powders would be collected by cyclone powder collector and discharged from the bottom as finished products. And, after that, the airflow would go into the fan along with the air return duct at the top of cyclone power collector. This system adopts a closed circuit and runs under positive and negative pressure. Because materials have a certain content of moisture, heat generated during grinding may lead air evaporation or swell in the grinding chamber so that the amount of airflow increases sharply. Besides, if the feed port and joints of pipelines are not sealed well, external air may intrude the grinding mill and lead imbalance of airflow. So, arranges exhaust valves at the air outlet of the fan to induce redundant air into the bag filter. After purifying, the redundant air is discharged. This arrangement can achieve both the balance of airflow and the eco-friendly production.
