ERTONG MAKE

Product Overview The Rotary Vane Feeder is a precision-engineered volumetric feeding solution designed for pneumatic conveying systems requiring airtight material control. Equipped with a hardened gear reducer and variable frequency drive (VFD) motor, this equipment complies with GB/T 10085-2018 (Gear Reducer Standards) and GB 755-2008 (Rotating Electrical Machinery) to deliver ±0.5% material dosing accuracy in cement, food, and chemical industries. Its robust construction ensures reliable operation under pressures up to 0.35 MPa, making it ideal for both vacuum and positive-pressure systems.
