Product Made in Japan

Manufacturer: KURIMOTO

Model: KSF-02, KSF-03, KSF-04

The SF Sharp Cut Separator is a centrifugal, pneumatic classifier making it possible to classify particles of up to 0.3 mm. On the SF Sharp Cut Separator, the cylindrical squirrel-cage rotor with multiple blades arranged in a radical pattern in order to classify, seal, and discharge fine particles rotates at a high speed to generate the centrifugal force due to rotary airflow and the centripetal force due to suction air, fixing up the cut size in balance between the centrifugal and centripetal forces. 

Features

Enable to classify submicron particles.
Reduce the secondary air consumption due to the introduction of the closed seal chamber.

Provide isolation-free particle size distribution.

Provide a sharp particle size distribution.

Minimize wear contamination.

Diminish the power consumption due to self-suction seal air

Construction
