Air classifier for fine powder processing
Enhance your production line with precise particle size control and energy-efficient classification, crucial for achieving consistent quality in materials ranging from lithium-ion batteries to food additives.

Classifies and Separates Powders and Granules
The Alpine Calciplex ACP from Hosokawa Alpine is an efficient classifier designed to enhance powder and granule processing across diverse industries. Using a high-speed classifier wheel, it separates fine particles while rejecting coarser material, ensuring uniform product quality. This makes it ideal for applications ranging from chemical and pharmaceutical processing to food manufacturing and recycling efforts. The ACP’s throughput supports high-speed, continuous operations and achieves energy savings of up to 25%. Constructed from robust cast iron, it is designed to cope with demanding environments while maintaining low maintenance requirements. Integration with existing systems is seamless, supported by pneumatic conveying. The ACP is suitable for operations demanding precise particle sizing and consistent output, and it meets industry standards for various applications. Customization options are available to meet specific needs, backed by expert engineering support.
