Ensuring the smooth movement of mined particles is vital for efficient processing. But what makes some materials flow like a dream while others clump and clog? Let’s explore the key factors that govern the flowability of mined particles.
The flowability of most bulk solids and ores are affected by the following characteristics and parameters:
- Particle size and size distribution,
- Maximum particle size and content of fines,
- Moisture content,
- Storage time at rest and under pressure,
- Consolidating pressure (i.e. height of the pile or silo),
- Temperature and weather conditions,
- Presence of oils, clays, talcs and/or additives,
- Chemical and mineralogical nature of the material.
The ease with which mined particles flow is a complex interplay of their inherent physical properties and external conditions. Optimizing flowability requires careful consideration and often manipulation of these factors to ensure efficient and reliable material handling throughout the mining process (Powders & Grains 2017).
