Bulk Bag Discharger Weigh Batching

June 7, 2016

Bulk Bag Discharger Weigh Batching A weigh batching bulk bag discharger system can improve batching efficiency and reduce ingredient and handling costs. A loss-in-weight bulk bag batching system includes a bulk bag discharger whose outlet is directly coupled to a feed control device such as a flexible screw conveyor. The feed device is typically supported by the bulk bag discharger support structure. A microprocessor based batch weigh controller is also included in any system. The following information is required to design a bulk bag unloader batching system: Batch size (min. and max.) Time to dispense batch (min. and max.) Tamped and untamped ingredient bulk density There [...]

Bulk Bag Unloader Showcased at PTXi Texas

October 8, 2015

Spiroflow Systems will exhibit a bulk bag unloader, aero mechanical conveyor and bin activator at the PTXi Texas Show in Houston, TX on October 13-14, 2015.  Visitors can visit the company in booth #113 with their regional representatives, Approtec Ran Le. Spiroflow will exhibit the T5 ‘low loading’ bulk bag unloader that is designed to empty bulk bags in process areas with restricted headroom.  The T5 bulk bag unloader is coupled directly to a flexible screw or other suitable conveyor which meters ingredients from the bag either volumetrically or by weight.  Ingredients can then be fed directly to mixing or other […]

Causes of Bulk Bag Dusting

June 3, 2015

Companies around the world transport and handle large volumes of materials in bulk bags but unloading bulk bags can be a dusty mess if not managed properly.  Let's examine what causes dust emissions. Bulk Bag Design:  Unless a bulk bag has been specifically designed to contain the fines present in a given product, particles can sift through the bag fabric.  This looks like smoke escaping from the bag as it is being handled and emptied.  Depending on the amount of fines present in the product, the particle size and its shape, coated fabric may be all that is required to [...]

Designing Bulk Bag Unloaders for Maximum Dust Control

May 13, 2015

Control Dust in Your Bulk Bag Discharging Operation
Controlling dusting and product spillage, while safely unloading bulk bags, is an industry wide challenge.  Many times standard, off-the-shelf bulk bag unloaders are utilized in a new process without a thorough understanding of the nature of the product.  This often results in the need for an often expensive retrofit assembly after installation and unnecessary commissioning delays. What should be considered to ensure dust free bulk bag unloading?  Here are the key factors to keep in mind: The Supplier - Specialist suppliers offering bulk bag unloaders for material handling can supply several types of equipment with dust containment options suitable for [...]

Training – Critical to Bulk Bag Unloading Success

April 11, 2014

Training is one of the most overlooked keys to bulk bag unloading success.  Properly trained operators facilitate a safer, cleaner and more productive bulk bag unloading operation. Key Bulk Bag Unloading Tasks That Require Specific Operator Training Placing the Bulk Bag in the Bulk Bag Unloader:  In most cases this is a simple task requiring only the attachment of the bulk bag lifting loops to the lifting frame used to place the bag in the bulk bag unloader.  However, when certain types of liners are involved the operator must know how to safely use the bulk bag unloader's liner tensioner [...]

Solving Bulk Bag Unloader Dusting Problems

April 2, 2014

Solve bulk bag dusting problems
The most common problem with unloading bulk bags is dusting.  Frequently, bulk bag unloader operations are a dusty mess.  At best, this results in a housekeeping problem.  Product loss and quality control issues can arise and the worst case is a safety issue when dealing with ingredients that pose a health or explosion risk. FINANCIAL IMPACT OF BULK BAG DUSTING Ingredient Yield:  Every particle of ingredient that escapes the bulk bag unloading process and ends up on the floor reduces ingredient yield and increases cost.  Thinking of dusting at the particle level implies little financial impact.  The following example identifies [...]
