Title:
木質材料の非凝集マスから超微細粒度の粒子を分離するための装置及び方法
Document Type and Number:
Japanese Patent JP2008536722
Kind Code:
A
Abstract:
An apparatus and a method to separate particles having a first granulometry, between some hundredths of a millimeter and about 6 tenths of a millimeter, from an incoherent mass of woody material consisting of particles of wood and contaminants, having a second granulometry between some hundredths of a millimeter and about 10 mm. The apparatus has fixed screening elements, substantially tubular in shape, inside which rotary members are mounted rotatable, which impart to the mass a determinate centrifugal force. The fixed screening elements are provided with a plurality of through apertures through which the particles having the first granulometry pass. The apparatus also has command members which impart to the rotary members a determinate peripheral velocity such as to apply to each unitary quantity of mass a centrifugal force sufficient to expel the contaminants having the first granulometry through the through apertures.
