| (54) | Pneumodensitometric vibrating separator for sorting of heterogeneous bulk products |
| (57) This invention covers a separator consisting of a vibrating pneumodensitometric table
ensuring a homogeneous fluidizing action by the sandwich shaped perforated table (1),
the upper part of which is consisting of a finely perforated metal plate while the
lower part (3) is consisting of synthetic fabric; the table (1) has a uniform motion
favoured by its centered configuration and sturdy fastening to the side frames (7),
the unidirectional vibrating motion being achieved by two electrovibrators (11), interconnected
by a rugged tubular cross member (12) transmitting the vibratory motion to the side
frames (7) of the table (1), while this unidirectional vibratory motion forms an angle
(α) with the longitudinal table plane; this angle may be varied according to the material
to be sorted and directed through the center of gravity (G) of the vibrating section
of the machine. The supporting structure (15) on which the table (1) is resting also
supports a dust filter (21). A special device (24) located between the table (1) and
the filter (21) provides for catching of any air entrained matter. (Fig. 5). |
