Summary
This study numerically investigates wet agglomeration, revealing that granule growth follows an exponential pattern. A phase diagram predicts granule survival based on particle size and liquid properties.
Area of Science:
- Chemical Engineering
- Materials Science
- Particle Technology
Background:
- Wet agglomeration is crucial in various industrial processes.
- Understanding granule growth dynamics is key to process optimization.
- Numerical simulations offer detailed insights into complex particle interactions.
Purpose of the Study:
- To numerically investigate the wet agglomeration process.
- To understand the growth dynamics of a single granule in a dense particle flow.
- To identify key parameters influencing granule growth and survival.
Main Methods:
- Discrete Element Method (DEM) simulations were employed.
- Capillary and viscous forces between wet particles were modeled.
- Analysis focused on accretion and erosion rates of wet particles.
Main Results:
- Granule size exhibited exponential growth over time.
- Growth dynamics are linked to liquid conservation and available wet particles.
- A phase diagram was developed based on primary particle diameter and size span.
Conclusions:
- Granule growth is predictable and influenced by material parameters.
- The proposed phase diagram effectively separates growth and non-survival domains.
- This research provides a framework for optimizing wet agglomeration processes.

In precipitation gravimetry, the precipitating agent should react specifically or selectively with the analyte. While a specific reagent reacts with the analyte alone, a selective reagent can react with a limited number of chemical species.
The obtained precipitate should be either a pure substance of known composition or easily converted to one by a simple process, such as ignition or drying. In addition, the precipitate should be insoluble and easily filterable. In general, filterability...

5.6K
The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large surface-to-mass ratio, where adsorption is promoted. For instance, in the precipitation of silver chloride, silver ions are adsorbed on the surface of the colloidal particles, forming a primary layer. This layer attracts ions of opposite charge (such as nitrate ions), forming a diffuse secondary layer of adsorbed ions. This electric double layer...

Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles visible to the naked eye or seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. The suspended particles in a suspension settle out after some time of mixing. The separation of particles from a suspension is...

Fluid dynamics is the study of fluids in motion. Velocity vectors are often used to illustrate fluid motion in applications like meteorology. For example, wind—the fluid motion of air in the atmosphere—can be represented by vectors indicating the speed and direction of the wind at any given point on a map. Another method for representing fluid motion is a streamline. A streamline represents the path of a small volume of fluid as it flows. When the flow pattern changes with time, the...
