The chemical process industries (CPI) have many applications that require classifying or separating solid materials. Examples of separation or classification processes include those operations that attempt to isolate specific material fractions according to particle size, scalp off the coarse fraction of a material stream, de-dust the fine fraction of a material stream or remove the contamination from a...

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 research being conducted at Ghent University in Belgium. The instrument is being used to continuously monitor the granulation...

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 solid materials to cake can lead to flow problems that will adversely affect your process. For situations where material caking disrupts gravity flow, a...

Gear units play a critical role in a diverse array of chemical process industries (CPI) facilities, to match the speed of a selected driver with the speed of the driven equipment. Today, they are used extensively in pumps, turbines and compressors, in material-handling units (such as conveyers and stackers), and in other equipment, including mixers, kneaders and extruders. This article discusses...

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...
