Solids Handling

Focus on Agglomeration And Granulation

Using PAT to monitor and control granulation Malvern Instruments Granulation is an important operation used for tableting, but its control can be challenging. The Parsum inline particle-sizing probe is being used as a PAT (process analytical technology) instrument in granulation…

Overcoming Solids Caking with Flow Aids

Using gravity to initiate flow in the discharge of solid materials from bins and hoppers is the simplest, and often best, approach to solving solids-handling challenges. However, not all solid materials flow well by gravity alone. The propensity for fine…

Powder & Bulk Solids Show Preview

The International Powder & Bulk Solids Conference and Exhibition is taking place May 6–8 at the Donald E. Stephens Convention Center in Rosemont, Ill. Featuring a large expo hall and a variety of technical sessions, as well as some hands-on…

Solids Drying: Basics and Applications

Adjustment and control of moisture levels in solid materials through drying is a critical process in the manufacture of many types of chemical products. As a unit operation, drying solid materials is one of the most common and important in…

This system aids in dry-powder discharge from bins or silos

The Promo-Flow Discharge Aid consists of an internally mounted screen and an externally mounted vibrating apparatus that is designed to aid in the discharge of dry powders from silos and bins. The vibrating element transmits vibration directly into the product,…

A bulk-materials conveyor with favorable space utilization

The En-Masse conveyor moves bulk materials while optimizing space utilization with its large size-to-capacity ratio. Useful in applications including boiler feed, receiving, distribution and ash handling, this conveyor’s totally enclosed framework minimizes area dusting and loss of material. Capable of…

This new feeder touts higher flexibility

The new ProFlex V vibratory feeder (photo) features two alternative discharge lengths to offer maximum flexibility in process integration. By turning the feed hopper of the new chute feeder in 90-deg steps, it is possible to achieve four different discharge…

Building a Better Weighing Instrument

Like most of the world, weighing instrumentation has gone digital and gotten connected. Not only do today’s scales, weight transmitters, check weighers, and other weighing equipment include more modern technological advances, but the up-to-date improvements also provide contemporary solutions for…
