What is a Multi-Port Diverter?

  • July 10, 2019

A Multi-Port Diverter is an integrated and automated solution for diverting and/or converging dry solid materials. Depending on the application, a multi-port diverter can be designed to transport materials from a single source or several sources toward any number of destinations.

Wye Line Diverter vs. Flex Tube Diverter: What’s The Difference?

  • April 26, 2019

The Wye Line Diverter and the Flex Tube Diverter are among Vortex’s most popular diverter valves for pneumatic conveying applications.

There are two primary factors when considering the Wye Line Diverter and the Flex Tube Diverter. Those being :

  • Concerns for material cross-contamination
  • Available space/stack-up height

Standing Column vs. Flowing Column: What’s the Difference?

  • December 14, 2018

In process engineering, for every solution to a consideration, three more considerations often arise. Material conveyance and valve selection are no exception. This white paper will address the difference between a standing column of material versus a flowing column of material, as well as considerations to be made when selecting a process gate to address each.

A “standing column” describes material accumulation above and below the gate while a “flowing column” describes materials freely passing through the gate.

The primary difference is that a “standing column” describes static materials at rest, while a “flowing column” describes suspended materials in motion.

What is an Air-Gravity Conveyor?

  • August 20, 2018

An air-gravity conveyor is a device for moving a variety of light-weight, fluidizable dry bulk powders. The conveyor consists of a rectangular chamber separated by an air-permeable, porous media. The media is placed along a horizontal plane to separate two chambers within the conveyor: An upper chamber to handle the material being conveyed, and a lower chamber to handle compressed air.

Things to Consider When Diverting or Converging in Dilute Phase

  • April 30, 2018

Dilute phase conveying is described as low pressure, high velocity material movement. Oppositely, dense phase conveying is characterized as high pressure, low velocity material movement.

If material characteristics and application parameters permit, dilute phase conveying is often preferred because it can be more energy efficient and can improve process efficiencies by conveying materials at higher rates of speed. However, many considerations must be made when designing a dilute phase pneumatic conveying process.

This article will address just a few of the many considerations that must be made before selecting valves to divert or converge dry materials in dilute phase.

Vortex Pivoting Chute Diverter Lets You Shift on the Fly

  • February 21, 2018

When the need arises to divert dry bulk material during gravity flow situations, one normally considers a typical flapper style diverter for the application. In applications where the sealing of non-abrasive, fine material is involved, the flapper is a perfect choice. There are applications and material handling situations, however, where a different style diverter might offer distinct advantages over a flapper. The Vortex Pivoting Chute Diverter embodies those advantages.

Orifice Gate vs. Roller Gate: What's the Difference?

  • January 30, 2018

Since their conception decades ago, the Vortex Orifice Gate and the Vortex Roller Gate have been two of Vortexs most popular solutions for handling dry bulk solid materials. By their simplest definitions, both the Orifice Gate and the Roller Gate are slide gates. However, the application benefits for each gate can be quite different.

Safeguard Technologies for Dry Bulk Material Handling

  • January 5, 2018

When designing a system for dry bulk material handling, it is important to consider all possible scenarios a slide gate may face during its life cycle  and equip it to appropriately handle those obstacles as they arise. For this reason and as a safety precaution, it is beneficial for a slide gate to be equipped with both a fail-safe air tank and a vented ball valve.

Controlling upstream and downstream influences on loss-in-weight feeders

Powder Bulk Engineering

  • Sep 1, 2018

Loss-in-weight (LIW) feeder performance is affected by a number of influences, both internal and external to the feeder and feeder process. Understanding the significance of these influences is critical for achieving optimal performance. This article will describe some strategies to help ensure accurate weighinhg with your LIW feeder.

Conquering the Main Wear Factors in Diverter Valves

Powder & Bulk Solids

  • March 15, 2018

A diverter valve is used to divert material from one source to different destinations in a pneumatic conveying system or a gravity pipe. Pellets, granules or fine powders passing through the diverter valve cause wear along the valve’s passage, especially with abrasive products as used in the mineral and cement industries. Examples are raw meal, lime, fly ash, bypass dust, clinker, cement, petcoke and lignite to name a few. Diverter valves that have been designed with main wear factors in mind make it possible to convey even highly abrasive powder bulk materials economically and reliably. They also enjoy a long service life and are easy to maintain.

Nut Butter Manufacturer Modernizes Plant Operations

Food Engineering

  • Jun 1, 2017

The complete material handling system provided by Coperion K-Tron includes several pneumatic transfer lines for various stages of the peanut butter process. First, raw peanuts are vacuum conveyed direct to a peanut roaster. After the peanuts are roasted, a second line transfers them under vacuum to the blancher. Once the peanuts are blanched, they are then vacuum conveyed to yet another line. There, they are metered via a Coperion K-Tron weigh belt feeder to a screw conveyor, and both sugar and salt are added to the nuts via Coperion K-Tron loss-in-weight feeders

Defining Feeder Accuracy For Continuous Processing

Processing Magazine

  • May 15, 2017

Continuous processing is a manufacturing practice that has been used in the plastics, chemical and food industries for decades. Although primarily used for liquid processing, the innovations made in dry powder feeder technologies have enabled the use of continuous dry ingredient feeding for a variety of applications.

Optimize Feeding to Make More Money in Twin-Screw Compounding

Plastics Technology

  • April 1, 2017

Every business want to increase profits. Companies can deploy many strategies to do so that can fall across various areas of the business, such as reducing inventory, negotiating lower prices from suppliers, or increasing marketing efforts, to name a few. When it comes to operations, the capital equipment is often already in place and is therefore a sunk cost. Increasing profitatbility in this case is usually depends on maximizing productivity of these assets. For twin-screw extrusion processes, this is most easily achieved by increasing throughput rate, thereby spreading operation costs over a greater amount of product produced in the same unit of time.
