The speed of belt feeding is controlled by the high-performance two-speed motor, the thickness regulator and the breaking door. It is mainly used for packing bulk, granular and coarse powder materials and is designed into the forms of single scale and double scale; 

• With imported touch-screen control instrument, weighing sensor and pneumatic actuator, it has high measurement accuracy and stable performance;
• It has automatic error correction, positive/negative deviation alarm, fault diagnosis and other functions;
• The belt conveyance and feeding mode combining the two-speed motor and the thickness regulator is adopted to guarantee conveying speed and accuracy;
• The conveyance and feeding device is equipped with a scraper, which prevents materials from entering to inner sides of the belt and causing belt slip;
• The relict-free design of the sealed bag-holding mechanism, the door panel and the bag-returning powder device prevents residue and dust;
• The easy-to-operate belt-slip regulator and V-belt pre-tightening regulator can be maintained easily;
• Unique double-layer design can prevent side leakage of the material;
• The parts contacting with materials are made of stainless steel and have a long service life.
