  • Protecting against cross-contamination

    Protecting product from cross-contamination is critical, especially when it comes to seed and pulse crops. Your conveyance is where the risk for contamination is usually at its highest. This necessitates constant clean-out measures that take up valuable time and are less than cost-effective. Here at Norstar, we believe that chain conveyance provides a well-balanced solution to the issue of ...

  • Flow monitoring with SlideControl - Case Study

    Application A producer of cement packs his product in a sack fi lling machine. The material comes from the storage silo through an air slide, fed in by a gate valve. The further material transport from the silo to the fi lling station occurs discontinuously by a number of screw conveyors, a bucket elevator and a conveyor belt. A central role in this application plays the ...

  • Corrosion resistant FRP reduces maintenance issues for water and wastewater treatment and control

    At this Wastewater Treatment Plant in Glendale Heights, IL, an aluminum slide gate had to be forced open using a front-end loader and a chain after seizing in place due to inevitable corrosion. The corrosive bond was so severe that the chain snapped upon the first attempt. The water and wastewater treatment and control industry is a prime example of how constant exposure to toxic elements can and ...

  • CDS-5: A Mayo Clinic and Thermotron Collaboration case study

    Cytogenetic testing is used for the diagnosis of many genetic disorders including congenital (prenatal and adult) and hematologic/oncologic disorders. Processing of these tests used to be labor-intensive with unpredictable test data. That’s why the Cytogenetic Laboratory at Mayo Clinic and Thermotron joined forces to increase the efficiency of cytogenetic test processing with the invention ...

  • Bringing precision to steel production - Case Study

    Aluminum and steel manufacturers use mass flow controllers to inject purification, stirring and shielding gases into their melting, casting and annealing processes. Precise, automated gas flow control reduces toxic emissions and material costs.  Final purification of aluminum is accomplished by bubbling a mixture of argon and chlorine gases through the molten metal. This process separates ...

  • Rotary batch mixer yields high-quality blends for powder metallurgy

    GKN Sinter Metals Inc. is the world's largest manufacturer of parts made by powder metallurgy, a molding process that produces complex shapes with a range of properties. Powder metallurgy offers benefits in part fabrication over competing metal processes. It is faster than forging or casting and permits the use of more performance-enhancing alloys than die-casting. GKN Sinter Metals, Auburn ...

  • Closed vessel or open channel UV disinfection systems

    Ultra violet disinfection is now a standard feature in most waste water disinfection systems. UV has also been adopted by the drinking water community, as a barrier against the chlorine tolerant species such as Cryptosporidium and Giardia. The technology is widely favored due to its non- chemical nature, the fact that no subsequent de-chlorination process is required, and its ability to be ...

  • Drum mixer compounds wide range of particles... and a modified paddle mixer solves a tricky problem

    In 1985 Mortex Manufacturing Co., Inc., bought a new rotary drum mixer in anticipation of expanding its line of chemical additives that are used to make decorative, nonskid coatings for concrete around swimming pools and on patios. The additives are mixed with white cement and white ...

  • New Maps from Old Photos: Measuring Coastal Erosion

    U.S. Geological Survey scientists and their coauthors from the California Coastal Records Project have found a way to use historical aerial photographs not just to see evidence of coastal erosion, but to accurately measure how much has occurred over time. Applying a low-cost technique called “structure-from-motion” to five sets of oblique aerial photos spanning the years ...

  • The most efficient distance between two points

    When bulk material characteristics, process parameters or space restrictions call for a flexible screw conveyor Deciding on the single most efficient method to move your material from point A to point B is a matter of simple deduction: just match your material flow characteristics, process parameters and space limitations to the performance windows and dimensional restrictions of ...

  • Weigh batching: the benefits of an automated system

    In many plants that batch-blend bulk products, weigh batching is a manual, time-consuming operation in which ingredients are weighed individually before being charged to a blender or other process vessel. A significant number of such plants could benefit from the installation of an automated weigh batching system. For small as well as large operations, an automated weigh batching system can pay ...
