PNEUMATIC SCREENSBack to list
Description: The innovative screening system was studied to improve and maintain a constant screening efficiency and to eliminate all the problems arising from heavy oscillating machinery.
The INSTALMEC pneumatic screen is static machine and has been created to overcome well-known problems of which:
-Expensive elastic suspensions subject to wear
-Heavy supporting structures
-Required periodical maintenance
-Variable efficiency between newly cleaned and plugged sieves
-Breakages of interconnecting sleeves
The INSTALMEC pneumatic screen consists of one or more circular sieves put into rotation onto which the material to be screened is deposited. The coarse fraction is sucked out after a complete rotation whilst the fine fraction falls onto a new screening deck or collects in the bottom and sucked out.
During the rotation of the sieves a system of counter-flow air keeps constantly clean screens.
In the traditional systems, the classification efficiency decrease after a few working hours.
In the Instalmec pneumatic screen, thanks to its continuous auto-cleaning, the efficiency is constant through time, avoiding periodic cleaning operations.
Through the cyclone, the various fractions are sent directly to the silos, without any additional handling.
The circular sieve decks are subdivided into light panel frames quick and easily replaceable.
