Small Bag Unloading Station

The Small Bag Unloading Station, also known as a Dust-free Unloading Station, is widely used for unloading powders and granular materials from small and medium-sized bags. It consists of a manual bin tipper, a back-pressure feeding platform, a grid, a lower sand trap, a vibrator, a filtration system, a dust removal system, and an air-blowing backflush bag. This product is easy to operate, observe, maintain, and clean, protecting the operator’s health. Constructed from stainless steel, the equipment is durable and finds wide application in industries such as food, new energy lithium batteries, and chemicals.

The Small Bag Unloading Station is commonly used for unpacking and unloading 25kg or 50kg bags of powdered/granular materials. Through manual bag opening and automatic tipping steps, materials fall into the storage hopper by gravity to complete the unloading process. Dust generated during operation is filtered out by the integrated dust removal device, allowing operators to work comfortably in a clean environment. A screening function can be added based on process requirements to remove impurities. It can also be integrated with a vacuum loader for vacuum feeding functionality.

During unpacking, the dust collection fan prevents material dust from dispersing. When unbagging and feeding materials into the next process, operators simply manually open bags and feed them into the system. Materials pass through a vibrating screen (safety mesh), which intercepts large lumps and foreign objects, allowing only qualified particles to discharge. Negative pressure formed by the centrifugal fan and suction pipes collects dust and fly ash during unloading, preventing dispersion, polluting the surrounding environment, and protecting operator health.

• Simple structure, low long-term maintenance costs.

• Ergonomic design for simple and comfortable operation.

• Pneumatic spring-assisted bin door opening for effortless operation.

• Filter mesh bracket prevents bag pieces or oversized objects from entering the bin.

• Dust removal with backflush improves the workshop environment.

• Sandblasted exterior for an aesthetically pleasing appearance.

• Flexible design allows for customization according to customer requirements.

• Wide range of applications, suitable for unloading various solid materials.

Pharmaceutical, Chemical, Food, Battery Materials, etc. Designed according to user needs, it effectively isolates operators from dust generated during unloading and related equipment. Under the negative pressure from the fan, dust is drawn into the filtration system, separating gas and material. When enough material accumulates, it falls into the storage bin by its own weight.

• Food Industry: Sugar powder, starch, salt, rice flour, milk powder, soybean powder, egg powder, soy sauce, fruit juice, etc.

• Pharmaceutical Industry: Industrial chemicals, traditional Chinese medicine powder, granulated pills, micro-pills, etc.

• Chemical Industry: Resins, coatings, industrial chemicals, cosmetics, paint, etc.

• Metals, Metallurgy & Mining: Aluminum powder, lead powder, copper powder, ores, alloy powder, welding rod powder, manganese dioxide, electrolytic copper powder, electromagnetic materials, abrasive powder, refractory materials, kaolin, lime, alumina, heavy calcium carbonate, quartz sand, etc.

• Other Industries: Waste oil, wastewater, dyeing wastewater, papermaking, additives, activated carbon, etc.

This series of equipment is suitable for unpacking, feeding, screening, and unloading small bags of materials in the pharmaceutical, chemical, and food industries. The dust collection fan reduces dust dispersion during unpacking.
It is particularly suitable for small-batch manual feeding and situations where materials are prone to agglomeration.
The feeding platform operates under negative pressure, preventing dust leakage and material loss during feeding, thus protecting the clean environment.
Built-in dust collector for easy maintenance; can also be connected to a central dust collection system.
Various main body materials are available based on user needs: 304 stainless steel, 316 stainless steel, carbon steel, etc.
An automatic cutting knife can be configured with automatic feedback for integrated equipment automation and interlocking.
The overall structure, height, and hopper can be designed and adjusted according to the user’s actual site layout.
Can be connected to positive/negative pressure conveying systems to supply materials to production lines.

• Wear personal protective equipment and a mask. Turn on the dust collector and use an air gun to clean the inside and outside of the unit.

• Turn off the dust collector and the main power supply. Remove the filter cartridge from the filter housing and clean it with an air gun. Replace the cartridge promptly if it is found to be ineffective.

• Remove the bottom vibrating screen mesh and clean it with an air gun. Check the mesh for integrity and replace it promptly if damaged.

• Clean areas prone to material adhesion with a damp cloth. After cleaning, dry the surfaces with an air gun and wipe again with a clean cloth. After completion, reinstall the filter cartridge and screen mesh onto the Dust-free Unloading Station.
