LOOSE MATERIALS SEPARATOR Russian patent published in 2010 - IPC B07B1/10 B07B1/46 

FIELD: process engineering.

SUBSTANCE: invention relates to separation of loose materials and can be used in agriculture for cleaning grain, flour-and-cereals and construction industries. Separator of longer loose materials comprises housing, loading branch pipe accommodating zigzag-like sieve made up of horizontal and inclined sections, pitched plates and deflectors. Zigzag-like sieve represents strings fitted on and tensioned between multiple-grooved pulleys. Adjacent grooves of drive pulley feature different diametres, while string space on horizontal section of strings increases with distance from loading branch pipe. Said pulleys feature different groove-to-groove distance on horizontal sections.

EFFECT: higher efficiency of grain cleaning, reduced height of separator.
