Manual bag opener for bulk solids discharging
Effortlessly open and empty bags while containing dust emissions, ensuring a clean and efficient processing environment for your bulk solids operations.

Opens, Empties, and Collects Dust from Bags
The Manual Bag Opener RSM from WAMGROUP streamlines material handling for industries ranging from food to chemicals. This user-oriented equipment features a compact design with easy access for cleaning. The RSM minimizes dust and material residue through a built-in fan-operated, air jet-cleaned dust collector, ensuring a cleaner processing environment. It accommodates diverse materials with options in carbon steel, 304L, and 316L stainless steel, and supports ATEX zone 22 applications. Its modular components make it adaptable across various pre-processing tasks, such as opening bags for wheat flour in milling or additives in chemical production. Optional enhancements include de-dusting filters and compatibility with the BINSWEEP Rotary Discharger for efficient downstream integration. The RSM’s robust design ensures durability and reliability, providing engineering support for process optimization.
