What is the Open Mouth Bagging Machine?

Double Screw Powder Bagging Machines is designed for powdery and less liquid materials, with floor type architecture, small structure volume and easy installation. It has high weighing accuracy, simple and convenient operation, high reliability and complete functions, and can be widely used in feed, grain, treatment of non-metallic minerals, fine chemicals, inorganic salt, rubber and plastic, leather, fertilizer and other industries.

We have increased the number of screws by replacing 1 screw with 2 screws. Two screws are divided into a large and a small screw, the large screw being responsible for fast feeding at the beginning of the feeding period and the small screw for precise feeding towards the end of the feeding period, controlling the weight accuracy. This design offers a balance of efficiency and precision, better matching the customer’s packaging needs and is suitable for a wider range of industries.
