Controlling upstream and downstream influences on loss-in-weight feeders
Powder Bulk Engineering
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
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
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
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
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.

Three ways to improve continuous loss-in-weigh feeding accuracy
Powder Bulk Engineering
The weigh accuracy of individual recipe ingredients for a continuos blending, granulation, or extrusion process has a direct effect on product quality and bottom-line savings. This article explains how to optimize continuous loss-in-weight feeder accuracy by separating plant vibration noise from true weight loss, controlling motor speeds during feeder refill, and compensating for process pressure fluctuations.

Unter Wasser besser granulieren
Kunststoffe
Ein neu entwickeltes Verschleißschutzkonzept für Lochplatten von Unterwassergranulierungen erhöht die Beständigkeit sowohl gegen Abrieb als auch Korrosion. Damit lassen sich die Produktionskosten insbesondere bei der Herstellung von Polyolefinen senken. Erstmals verfügbar ist dieser Verschleißschutz für eine leistungsgesteigerte Unterwassergranulierung von bis zu 70t/h Durchsatz.
