MTW Trapezium Grinding Mill is developed by our company's experts based on 10 years' R&D on grinding machines. It owns many independent patents, such as overall prick gear drive, internal thin oil lubrication system, arc-shaped air duct. All of these make it lead the trend of the milling industry in the world.
After broken materials are evenly sent to the grinding chamber of MTW Trapezium Grinding Mill,some materials are blown away by airflow to the powder concentrator for classification. 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.
