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 MTW European 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, SBM 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.

  • More Wear-Resistant Vulnerable Parts, Higher Using Ratio

    The grinding rollers and rings made of wear-resistant alloy are developed by SBM and scientific institutes together. Their service life is 1.7-2.5 times longer than traditional rollers and rings made of high manganese steel. Part of vulnerable spare parts adopt split structure which is helpful to save more expenditures on vulnerable parts.

  • Digitalized Processing, Higher Precision

    There are tens of lines of numerical controlling machine tools. Operations such as steel plates’ cutting, bending, planing, milling and paint spraying are all controlled numerically. The machining precision is high, especially for the core parts.
