2017 HOSOKAWA ALPINE Pulvis

The PULVIS is an energy-optimised grinding system for ultra-fine materials. The vertical, dry agitator bead mill features an integrated dynamic classifier. Its strength is the ultrafine and low contamination grinding of hard materials. 

Used on alumina powder Al2O3  only a dozen of times.

The Hosokawa Alpine Pulvis is a high-energy impact mill designed for the dry grinding of powders in the size range of d50 = 5 to 150 µm. It utilizes a combination of high-speed impact and shearing forces to achieve size reduction of various materials. This type of mill is commonly used in industries such as pharmaceuticals, chemicals, minerals, and others where fine and ultrafine particle sizes are required.

The Pulvis mill typically features a cylindrical grinding chamber with a rotor assembly containing grinding elements such as hammers or pins. Material is fed into the mill through a feed inlet and is subjected to intense collisions and frictional forces as it passes through the grinding zone. The high rotational speed of the rotor generates a strong airflow within the mill, which helps to classify the ground particles and discharge them through a screen or classifier located at the bottom of the mill.

One of the advantages of the Pulvis mill is its ability to produce narrow particle size distributions and high yields due to its efficient size reduction mechanism. Additionally, it can handle a wide range of materials, including heat-sensitive and abrasive substances, making it a versatile solution for various processing applications.
