Understanding and controlling particle size are essential for product quality, process efficiency, and overall performance in diverse applications such as pharmaceuticals, construction materials, paints, coatings, and food. Not just these, but metal powders used in manufacturing benefit from optimal sphericity and particle density for improved flowability.
Particle size is an indicator of quality and performance across different materials, including powders, suspensions, emulsions, and aerosols. In the paint and pigment industries, particle size affects appearance properties like gloss and tinctorial strength. For chocolate production, cocoa powder particle size impacts colour and lavor. Glass beads used in highway paint need specific sizes for optimal reflectivity. In cement production, particle size influences strength and setting time.
What is hammer milling, and how does it achieve particle size reduction?
Hammer milling is a high-energy process used to reduce particle size by impact. The process efficiently reduces particle size through impact and controlled adjustments. The material is fed into the mill’s chamber, where rapidly rotating hammers strike the particles repeatedly. As the material collides with the hammers, it shatters and breaks down through the combination of hammer blows, wall collisions, and particle-on-particle impacts. Perforated metal screens or bar grates cover the mill’s discharge opening, where the coarse material is retained for further processing while properly sized material passes through.
The finished particle size depends on screen (or bar grate) size, shaft speed, hammer size, and hammer configuration. These factors can be adjusted individually or in combination to achieve the desired particle size.
What are the benefits of using hammer mills for particle size reduction?
Hammer mills can handle a wide range of materials, from soft and fibrous to hard and brittle. Their adaptability makes them suitable for various industries and applications. They are known for their high efficiency in reducing particle size.
Their straightforward design ensures ease of use and maintenance, along with simple operation and management.
What is dry granulation, and why is it important?
Dry granulation is a method used to create granules from powder without the use of water. Unlike wet granulation, which involves binders, dry granulation relies on compaction and compression techniques to form cohesive granules.
One key advantage of granulation is its cost effectiveness compared to wet granulation, as it eliminates the need for moisture and drying stages. This technique is particularly beneficial for materials sensitive to moisture or solvents during the formation process, ensuring the integrity of the granules while maintaining material quality.
The efficiency, cost savings, and compatibility with moisture materials make dry granulation a valuable process in industries such as pharmaceuticals.
