Q What are the working principles of the automatic bulk bag unloader?

The main steps include "Hoisting - Unpacking - Discharging - Bag Emptying". A forklift or electric hoist lifts the bulk bag to the feeding inlet. After the bag opening is secured, a cutter/blade assembly cuts open the bag, allowing the material to fall by gravity into the hopper below. Adhesive materials are assisted by vibrators for discharge, while an enclosed negative pressure dust collection system captures airborne dust throughout the process. After discharge, the empty bag is beaten to remove residue and then automatically conveyed to a collector, achieving dust-free and continuous unpacking.

Q Can the equipment be customized?

The equipment is highly adaptable and can be customizable on demand. Bulk bag weight (500-2000 kg) determines the load-bearing capacity and fixing structure of the lifting device; material properties (ultra-fine powder/granules, corrosive/flammable & explosive) dictate the silo body material (stainless steel 316L/carbon steel lined with wear-resistant layer) and explosion-proof rating; capacity (10-50 bags/hour) matches the number of unpacking modules; compact design is available for confined spaces, and special requirements such as metal detectors or magnetic separators can be added.

Q How is the equipment maintained?

Daily Maintenance: Before operation, inspect the wear of the lifting slings, the sharpness of the cutting blades, and the cleanliness of the vacuum filter screens. After operation, clean the residual material from the hopper and turn off the power and air supply. Periodic Maintenance: Lubricate the lifting pulleys and conveyor belt bearings weekly. Calibrate the cutting blade position and replace aged sealing components monthly. Test the performance of the dust removal fan quarterly, and disassemble and clean the cutter blade assembly to ensure no material accumulation or jamming.

Q Precautions

Before hoisting, confirm that the bulk bag is intact and slings are securely connected to prevent falling. Do not touch the unpacking area or hoisting parts during equipment operation; maintenance requires implementing a power-off and tag-out system. Strictly prohibit unpacking overweight bulk bags or bags containing hard objects to avoid equipment damage. For damp materials, pre-dry them to prevent hopper clogging. In flammable and explosive environments, ensure explosion-proof components are intact and regularly check grounding devices (resistance ≤10Ω).
