Feed manufacturing - Wikipedia

[citation needed] Soybean meal prepared for the fish industry is heavily dependent on the particle sizes contained in the feed pellets. Particle size influences feed digestibility. The particle sizes of fish pellet feed are influenced by both grain properties and the milling process. Properties of the grain include hardness and moisture content.

Tablet Hardness - an overview | ScienceDirect Topics

An inline particle size analyzer was used in conjunction with variate methods in a fluid-bed granulation process in one of the studies (Huang et al., 2010). The evaluation of inline monitoring of quality attributes, particle size, and particle size distribution, was conducted using the Parsum probe that is based on spatial filtering technique.

Chapter 4 Engineering Classification of Rock Materials

particle size, texture, hardness, and strength. Seismic velocity, weathering, and secondary cavities are prop-erties related to both the rock material and mass. Rock material properties can be described in the field using qualitative methods and simple classification tests, or, if necessary, in the laboratory using standardized tests.

Particle Hardness - an overview | ScienceDirect Topics

Knowledge of particle hardness is essential, therefore, particularly at the design stage of a plant, because it gives an indication of the need to take steps to avoid excessive wear of key system components. Scratch hardness is the earliest known type of hardness test, and in its simplest form is the ability of one solid to scratch, or be scratched, by another.

with compression. We need a range of particle sizes that is in harmony with the tablet size. Generally speaking, the smaller the tablet, the smaller the particle size. Likewise, the bigger the tablet, the big-ger the particle size. Particles smaller than 200 mesh (74 microns) are generally a problem for compression.

Particle size reduction and size separation | Clinical Gate

Introduction to size reduction. The significance of particle size in drug delivery has been discussed in Chapter 9 and some of the reasons for carrying out a size reduction operation have already been noted. In addition, the function of size reduction (also called comminution) may be to aid efficient processing of solid particles by facilitating powder mixing or the production of suspensions.
