Title:
AGRAVIC POWDER CLASSIFYING METHOD AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JP2668070
Kind Code:
B
Abstract:
PURPOSE: To provide a method and device for highly precisely classifying powder by pneumatically transporting in agravic state or in minute gravity state.
CONSTITUTION: In an agravic chamber 10, the powder is classified by a classification means 24 for pneumatically transporting the charged powder through a pneumatic transporting pipe 12 in laminar flow under agravic or minute gravity state and applying electric field to the laminar flow. The charged powder is accelerated in inverse proportion to the mass by applying electric field and then the powder is precisely classified.
