Product Description

Working Principle

After jaw crushers break large bulky materials to smaller ones, elevators lift materials to the hopper. Then, the materials are evenly and quantitatively sent to the grinding chamber of INR European Grinding Millby electromagnetic vibrating feeders. After grinding, materials are blown away by airflow to the powder classifier.The 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 enter the grinding mill and lead imbalance of airflow. So, INVECH 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.
