Case Study: Bulk Bag Unloader and Vacuum Conveyor System Automates Material Handling and Adds Cost Savings
Werner G. Smith, Inc. was awarded a long-term contract from a new customer which required the blending of a granular powder with an aqueous chemical solution. Under the terms of the agreement, the customer would provide the raw materials and WGS would make the product in accordance with the specifications set forth in the agreement. The job began at a time when WGS had extra capacity in one of its large reactors allowing the reactor to be dedicated for this process. Dedicating the unused processing space was an excellent way for WGS to maintain on-time deliveries while still accepting new work from other customers. The building where the product was intially made had no loading dock, which meant 55 lb bags of raw material had to be hauled and processed manually.
Application Review: Overcoming the Challenges of Handling Salt in Bulk
An Italian food processor added a new pasta line to meet growing demand for small batch, premium pasta. The granulated salt used for this process came in 2,000 lb bags, had a fine particle size and was hygroscopic in nature. The combination of these characteristics, coupled with the transportation time, left the processor with material that had formed large dense clumps inside the bag. The clumps of salt caused flow issues from the FIBC’s and created challenges for properly dissolving the salt in water to obtain the correct percentage of salinity. The Italian food processor reached out to Hapman to help with their material flow challenge.
Case Study: Custom Bulk Bag Unloading System Helps the Village of Gilberts to Maintain EPA Standards for Wastewater Treatment
To renew the 5-year National Pollution Discharge Elimination System Permit (NPDES), the Village of Gilberts, Illinois would be required to significantly reduce levels of Barium within public wastewater. Acheiving the new standards could not be done easily because reducing Baruim levels would result in higher Radium levels. To solve this complex wastewater challenge, the Village of Gilberts reached out to Baxter & Woodman, wastewater consulting engineers, to design and implement a custom wastewater treatment system.
Case Study: Basic American Foods Expands Plant Capacity in Record Time, Ensures Reliability with Pneumatic Vacuum Conveyors
A processor must expand its capacity and add new lines in half the time normally required for such a project. The material being conveyed is a very fine powder and can be problematic.
Application Review: Portable Bulk Bag Unloading - Chemical Company Charging Hoppers with Limestone Combining with Helix® Flexible Screw Conveyor
A chemical company had to periodically charge their holding hoppers with ground limestone. Due to the number of hoppers and their infrequent need for charging they did not feel that it was going to be cost effective to purchase a bulk bag unloader for each one.
Application Review: Hapman Maintains EPA Standards by Meter Feeding Enviroblend into a Dust Collection System
EPA standards required this company to feed Enviroblend® into their dust collection system at a precisely controlled rate of 30 pounds per hour so the emissions would be at an acceptable level. They also required a digital verification that the material was accurately discharging.
Application Review: Sweets Manufacturer Batching From Standard and Bulk Bags
A major manufacturer of sweets required a highly versatile system to convey and accurately weigh batches for mixing and discharge into a hopper before final processing into their calcium food supplement.
White Paper: Mixing Solutions and Slurries - Effectively and Economically Safely
A perpetual challenge in the chemical industry has been finding an ideal way to effectively mix solids and liquids to create optimal slurry – and at the same time, utilizing the least amount of floor space, energy and human resources.
Tech Brief: How Does an Iris Valve Work
Most of us are familiar with the iris diaphragm, a simple mechanism that can expand or decrease the opening of a circular hole. The iris mechanism is present in the world of dry bulk solids handling, where it’s called an iris valve. The iris valve’s function is to gently control the discharge of free flowing powders, granules, and pellets — including chemicals, food and dairy products, pharmaceuticals, minerals, and plastics — in gravity-flow applications.
Tech Brief: Top Equipment Design Considerations for Handling Bulk Chemical Powders
Successful conveying and handling of chemical powders requires much more input than understanding a material’s properties, the desired convey rate and distance. Today’s manufacturers are faced with tighter margins, leaner operations, shorter lead times and greater environmental concerns. Maintaining plant and worker safety is paramount.
Tech Brief: Mitigating the Risk of Dust from Bulk Bag Discharge
Controlling dust is a constant challenge for any processor that handles dry bulk material. The hazards from dust span the health and safety spectrum from mildly irritating and unclean, to hazardous to health and explosive.
