Optimizing magnesium hydroxide concentrate preparation: the key role of particle size distribution

In industrial applications, magnesium hydroxide thick slurries are valued for their unique chemical and physical properties. However, the key to achieving high-performance magnesium hydroxide thick slurries lies in optimizing the particle size gradation. This article will explore the importance of particle size gradation and how this strategy can be used to improve the performance of magnesium hydroxide thick slurries.

The importance of granularity gradation

When preparing magnesium hydroxide thick slurry, the particle size gradation of the particles is crucial to increase the bulk density and improve the rheological properties of the slurry. By precisely controlling the proportion of particles of different sizes, a tighter particle arrangement can be achieved, thereby improving the overall performance of the slurry.

Optimization method of particle gradation

Traditional particle grading methods rely on experimentation and experience, which is time-consuming and inefficient. Modern optimization strategies use mixture regression design to determine the optimal particle ratio by establishing a particle gradation model. This method can significantly increase the solid content of the suspension system, thereby optimizing the performance of the magnesium hydroxide slurry.

Magnesium hydroxide production process

Magnesium hydroxide can be produced by a variety of methods, including the cost-effective calcium hydroxide method and the higher purity sodium hydroxide method. Choosing the right production process is critical to ensuring the quality and performance of magnesium hydroxide thick slurry.

Application of particle gradation in coal water slurry preparation

In the preparation of coal-water slurry, particle gradation also plays a key role. By controlling the particle size range of pulverized coal particles, an efficient close-packed state can be formed, thereby improving the concentration and stability of coal slurry. This principle also applies to the preparation of magnesium hydroxide thick slurry.

Preparation technology of magnesium hydroxide slurry

An efficient method for preparing magnesium hydroxide slurry involves preparing a highly concentrated aqueous magnesium hydroxide solution and premixing it. By adding stabilizers and viscosity reducers, along with strong stirring, a magnesium hydroxide slurry with high dispersion, low viscosity, and long-term stability can be prepared.

Particle size gradation plays a vital role in the preparation of magnesium hydroxide thick slurries. By optimizing particle gradation, not only can the bulk density of the slurry be increased, but its rheological properties can also be improved, thereby improving the application performance of the final product. Using modern optimization strategies and efficient preparation techniques, the excellent performance of magnesium hydroxide thick slurry in various industrial applications can be ensured.
