Whirl-Air-Flow can provide you with a bulk bag unloader that effectively meets your process requirement needs. Our 50 plus years of experience handling dry flowable bulk solid materials assures you of an unloading system that will quickly and efficiently unload your product. Our unloaders are designed to handle a variety of bulk bag sizes. and our "closed system" design eliminates contact with the contents of the bulk bag.
Our "closed system" design starts with a 180 degree access door allowing easy access for connecting and disconnecting the bulk bag. A positive dust tight connection is made by fitting a pneumatic cord around the pipe and pressurizing it, trapping the bag's discharge spout against the pipe. This allows the operator to remove the bag's discharge tie and start product flow without exposure to the product.
Bulk bags are safely supported in the framework by a full sized, compressed air driven vibratory pan. Our unique "silent" vibrator is fully adjustable for the right amount of vibration to induce product flow.
Pneumatically operated bag squeezers are available for products with difficult flow characteristics. to dislodge material and prevent bridging. They can be programmed to operate in sequence with vibratory pan or operator controlled.
An optional iris flow control valve is available to adjust or stop the material flow, so that partially used bags can be changed out. For bulk bags having a liner, a spring loaded bag tensioner is used to secure the liner to the top of the unloader's frame during the unloading cycle to prevent washout.
If your application needs require a multi functional bag unloader. WAF offers a combination model that can accommodate bulk bags as well as function as a bag dump for paper bagged materials.
If your application needs go beyond getting dry hulk material out of a bag, Whirl-Air-Flow supplies systems that will convey your product into storage or process and include weighing or blending.
The Whirl-Air-Flow bag dump/tilter systerm is a self-contained, compact system for manual emptying bags or small drums, that eliminates dust by capturing it and returning it to the hopper. The bag dump's downdraft design draws dust through the loading grate as the bag is emptied. Airborne dust is then stopped by bags in the filter section. These filters are continuously cleaned with pulse jet air, allowing the collected dust to fall into the hopper.
Whirl-Air-Flow's bag compactor can be mounted directly to a WAF bag dump for dust free operation or operated as a stand alone unit. It provides a simple, silent method for compressing used bags into bundles, making them easier to handle and dispose of.
