Brief description:
Stainless Steel Bulk Bag Unloader Big Bag Unloading Station is a specialized equipment designed for feeding and unpacking large packaging bags, specifically addressing issues such as dust overflow and excessive dust emissions during the feeding process. It is primarily used for unpacking and unloading granular and powdered materials contained in bulk bags, including food ingredients, chemical raw materials, additive, lithium battery industry, rubber and plastic industries, energy batteries, paint industry, and the coatings industry. Two models are available:
1. D-TL-1



The Big Bag Unloading Station lifts the bulk bag to the top of the feeding inlet of the equipment through the electric hoist. The inner bag of the big bag is manually fixed at the clamping mouth of the equipment, and the big bag is clamped and sealed by the bag holder to prevent dust overflow. The bag is then manually opened and unloaded, aided by devices such as beaters and vibrators, to facilitate complete unloading of the material inside the bulk bag. The unloaded material can be directly fed into the equipment of the next process or used for unpacking and feeding in pneumatic conveying or screw conveying systems.
1. D-TL-2



D-TL-2 series big bag unloading machine added the feeding function of small bag packaging materials based on D-TL-1 Big bag unloading station. When unpacking big bags, it is equivalent to D-TL-1. When unpacking small bags, the dust collection fan of the dust collection box can avoid the material dust flying everywhere. When the material is unpacked and poured into the next process, it only needs to be manually unpacked directly into the system. When the material passes through the vibrating screen, the big size material and foreign matter can be intercepted, so as to ensure the removal of particles which are unqualified.
Main features:
1. Meet GMP certification and food hygiene certification standards. Applicable field: food, chemical, additive, lithium battery industry and other industries.
2. According to different materials it is made of mild steel, stainless steel 304, stainless steel 316, Ti steel, etc.
3. Simple structure, easy operation, enclosed and no dust flying. Improve the working environment, sealingwell, no leakage, less residue.
4. According to the variety of packaging specifications, bag filling rate and material characteristics, etc., it can be designed according to customer requirements.
5. It can work with vacuum feeder, screw conveyor, vibrating feeder and other conveying machines to transfer the material into next production equipment, such as mixer, silo, reactor, vibrating screen, etc.
