Calculating volumes of solids in piles as they are poured into various shaped containers can be important information for solids-handling applications. The following set of equations represents guidance to help determine solids volume in these cases. Solids in containers Solids fed through a nozzle into a cylindrical or rectangular silo normally form a partial cone of a complex shape when the material is...

Mixing and blending of bulk solids is a common processing step in many industries. For example, in pharmaceutical manufacturing of solid dosage formulations (tablets or capsules), small amounts of a powdered active drug are carefully blended with excipients, such as sugar, starch, cellulose, lactose and lubricants. With foods, many powder-form consumer products result from custom mixed batches; consider...

Rotary valves are used almost universally in pneumatic conveying systems. They serve three main functions: 1) to provide a pressure-seal (airlock) between two adjacent processes, 2) to provide solids metering (feeding) and 3) to provide a combination of solids metering and a pressure-seal for feeding solids into a pneumatic conveying system. Rotary valves are common devices for feeding solids into a...

Dry, granular solids can be conveyed in a number of ways. Two common devices for transporting granular solids are the angular-pitch vibrating conveyor and the horizontal differential-motion conveyor. The variability in the design and performance between the two types stems from the differences in the kind of motion required to move the mass in one direction. The most significant difference between the two...

In the processing environment, powders often appear to exhibit variable flow behavior, which can be the cause of significant inefficiency in the form of unplanned shut downs or compromised product quality. However, the reality is that powder flow properties are influenced by a diverse array of parameters from air and moisture content to particle size, shape and surface charge.  Figure 1. The new...
