Whirl-Air-Flow can provide you with a bulk Bag Unloading System 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° 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 the 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.
