Ultrafine classifier for toner and pigments
Achieve unparalleled precision in classifying fine powders essential for high-quality toner and pigment production, ensuring optimal particle separation and minimal fine fractions. Maximize efficiency with low energy consumption and easy maintenance designed to handle demanding classification challenges effortlessly.

Classifies and Dedusts Powders with High Precision
The TSP and TTSP Ultrafine Classifiers from Hosokawa Alpine are engineered to address the demanding precision classification needs in various industries. They feature a patented dispersion method where feed material is transported through classifying air, achieving exceptional cut precision and minimal fine fractions. Designed for applications such as toner, pigments, and powder coatings, these classifiers support industries from fine chemicals to additive manufacturing.
The TSP model offers one-stage classification while the TTSP model enhances precision with two-stage classification, improving throughput and loading factors. Operating continuously, they maintain low pressure loss, reducing the need for large motors and ensuring energy efficiency. Constructed in stainless steel, these units facilitate easy disassembly and quick cleaning, reducing downtime. Available in various sizes, they can be tailored to specific needs, and comply with stringent health and safety standards, making them suitable for sensitive applications. Perfect for fine chemical producers, pharmaceutical manufacturers, and powder coating industries seeking reliable, efficient classification solutions.
