Big-Bag Dischargers
SPBBE-ADS modular Big-Bag (FIBC) unloading stations with integrated anti-dust sealing system.
SPBBE-ADS Big-Bag Discharger with Anti-Dust System is an industrial unloading station engineered for dust-free, safe and controlled discharging of powder or granular materials from Big-Bags (FIBCs). Taking into account the operating height of the loading equipment, its modular frame adapts to different Big-Bag sizes for maximum plant flexibility.
Equipped with a spring-loaded sealing ring with telescopic anti-dust tube, untying chamber, vibrating discharge cone, 0.26 kW electric vibrator and flexible sealing bellows, the SPBBE-ADS guarantees clean and continuous feeding of plastic granules, PVC dry-blend, calcium carbonate, pigments, dry mortar and chemical powders.

- 01
The Big-Bag (FIBC) is lifted by its loops onto the lifting cross and positioned over the sealing ring using a forklift (S/C models) or the integrated electric hoist and monorail (M model).
- 02
The operator safely unties the Big-Bag discharge spout through the sealed inspection hatch; the spring-loaded telescopic anti-dust ring tensions the spout downwards to create a dust-tight seal.
- 03
The 0.26 kW electric vibrator mounted on the discharge cone (and optional pneumatic bag massagers) activates to break bridges and promote smooth material flow.
- 04
Material flows cleanly through the Ø273 mm outlet directly into a screw feeder, rotary airlock valve, or vacuum/pneumatic conveying line.
- Minimal maintenance requirement and heavy-duty long-life construction

- Dust-free working environment and zero material loss or contamination

- Easy installation and plant adaptation thanks to the modular telescopic frame

- Wide range of optional accessories and full compatibility with different Big-Bag sizes

- Maximum operator safety provided by the enclosed untying and anti-dust chamber

- Direct flange connection to downstream conveying, dosing and weighing equipment

Dust-Free, Safe and Flexible Big-Bag Unloading Technology

Vibrated & Sealed Discharge Hopper Promoting Smooth Flow
Operator safety is maximized through the enclosed bag untying chamber and integrated anti-dust sealing system. The vibrated conical hopper and telescopic structure compatible with various Big-Bag dimensions ensure uninterrupted unloading even for cohesive or poorly flowing powders.
Modular Steel Frame Adapting to Any Plant Headroom
Its rugged, compact, and modular steel construction integrates effortlessly into existing production lines. Loading options via forklift, overhead crane, or integrated monorail hoist provide optimal ergonomics and minimal maintenance costs even in low-headroom facilities.
SPBBE-ADS Series Configurations (S / C / M)
Big-Bag discharging stations feature frames built from modular components and are manufactured in S, C, or M configurations depending on the Big-Bag loading method.
S-MODEL · Standard Modular Frame with Lifting Cross
Standard modular frame equipped with a removable lifting cross for suspending the Big-Bag. The cross is lifted directly by a forklift or an overhead plant crane and seated onto the upper frame.
C-MODEL · Upper Frame with Forklift Guide Channels
Equipped with an upper frame featuring integrated guide channels that allow the Big-Bag to be slid directly into place by forklift tines without needing an overhead crane.
M-MODEL · Integrated Monorail & Electric Chain Hoist
Includes an integrated IPE monorail beam and electric chain hoist on the upper frame, allowing the Big-Bag to be lifted from floor level and travelled into the station without a forklift.

Frequently Asked Questions
What is the difference between the S, C, and M models in the SPBBE-ADS Big-Bag discharger series?
The SPBBE-ADS..S model features a removable lifting cross loaded via forklift or overhead plant crane. The SPBBE-ADS..C model has an upper frame with forklift guide channels so the Big-Bag can be slid directly into place by a forklift. The SPBBE-ADS..M model incorporates an integrated IPE monorail beam and electric chain hoist to lift the Big-Bag from floor level without requiring a forklift.
How does the Anti-Dust System (ADS) work?
A spring-loaded telescopic sealing ring clamps around the Big-Bag outlet spout and tensions it downwards while a flexible bellows isolates vibration, creating a completely sealed path so no dust escapes into the workplace during untying or discharging.
Can the SPBBE-ADS be manufactured in stainless steel for food or corrosive chemical applications?
Yes. In addition to painted carbon steel, both the product-contact surfaces and the complete frame of the SPBBE-ADS series can be manufactured in AISI 304 or AISI 316L stainless steel.
