Automatic Sack Discharging
An Automatic Sack Discharging System (also called Automatic Bag Emptying Station) is used in industries to efficiently and safely unload bulk materials from bags (usually 25–50 kg sacks) into a process line without manual handling. These systems are widely used in food, chemical, pharmaceutical, plastic, and mineral industries where hygiene, dust control, and productivity are important.
The Automatic Sack Discharging System is a fully automated solution designed for the efficient, safe, and dust-free emptying of bulk material sacks (typically 25–50 kg). It eliminates manual handling, improves productivity, and ensures hygienic material transfer into downstream processes such as silos, mixers, or conveyors.
🔹 Overview
-
Purpose: Automatically cut open and empty sacks of powder or granules.
-
Capacity: Typically 400–1,200 bags/hour (depending on model).
-
Bag Size: Usually 25–50 kg standard sacks.
-
Materials Handled: Flour, sugar, cement, plastic pellets, chemicals, minerals, etc.
🔹 Working Principle
-
Bag Feeding: Bags are placed on a conveyor (manually or via pallet lift).
-
Cutting Mechanism: Rotary blades, knives, or a drum system automatically cut open the sack.
-
Material Discharge: Contents are emptied into a hopper, silo, or conveying system.
-
Dust Control: Integrated bag filters & extraction systems capture dust, ensuring clean operation.
-
Empty Sack Disposal: Empty sacks are compacted or sent to a baling system for disposal.
🔹 Key Features
