Definitions
- This invention relates to vibratory sifters, the term "sifters” being used in a broad sense to include the various sieves, screens and the like by which the materials can be screened, graded or separated.
- the term "materials” is intended to describe solids, liquids, items or any other substances to be separated by size.
- material to be separated is supplied to the top of a vibrating screen, oversize material being retained on the top of the screen while undersized material passes through the screen. Oversized material is removed from the periphery of the screen, normally by way of an opening in a peripheral wall surrounding the screen.
- a sifter comprising a resiliently supported screen, means for subjecting the screen to a vibratory movement, means for collecting undersized material passing through the screen and an aperture through the screen adjacent to and inside its periphery through which oversized materials from the top of the screen are dischargeable.
- the apparatus comprises a plurality of vertically spaced screens each having a discharge aperture for oversize particles adjacent to and inside its periphery.
- the vibratory movement is created by vibrator means situated below the screen(s) and acting to create a three dimensional motion of rotational character having upward and downward components in the movement.
- a discharge chute for oversize material is located beneath the or each aperture, directing oversize material away from the centre of the machine.
- the collecting means for undersize material has an inclined base and a discharge at the periphery of the sifter.
- the screen comprises a mesh supported by a peripheral tensioning frame.
- the mesh is bonded to the tensioning frame. Alternatively it may be clamped or otherwise fixed to the frame.
- the oversize material outlet is located entirely below the level of the mesh of the screen.
- a screen for a vibratory sifter comprising a peripheral tensioning frame supporting a mesh which has an aperture for oversize material adjacent to and inside the tensioning frame.
- the mesh is bonded to the tensioning frame.
- the mesh and tensioning frame have a circular periphery.
- a vibratory sifter comprises a cylindrical base support 10 on which is supported by an annular series of compression springs 12 a vibratory assembly comprising a cylinderical sifter chamber 14 in which is mounted a sifter screen 16 above a collecting pan 18 for undersize material passing through the screen, the pan 18 having a peripheral discharge chute 20 extending through the side wall of the chamber 14.
- the chamber 14 extends upwardly from a base member 22 having a central mounting ring 24.
- An electric vibrator motor 26 is supported by and below the ring 24.
- the motor shaft projects above and below the motor casing and is fitted with relatively angularly adjustable eccentric weights 28, 30.
- Fig. 1 shows a perspective view of a circular screen.
- the screen comprises a circular peripheral tensioning frame 30 having a mesh 32 bonded, clamped or otherwise fixed to it.
- a mesh 32 bonded, clamped or otherwise fixed to it.
- Fig. 3 and 3A show that discharge chute 38 for oversize material is located below the aperture 34. and that the screen is replaceable, for example, for cleaning purposes, by removably attaching in the chamber 14 between an upper section 14A and a lower section 14B, the sections being clamped together by any suitable means.
- a multiple progressive sifting operation can be achieved by fitting one above the other in the sifting chamber 14, a plurality of screens, the mesh size of which decreases progressively downwards, each screen having fitted therebelow a discharge chute 38 for over size material, each leading to a separate collecting means, the undersize material falling through an upper screen to the next below screen where it is subject to a further sifting operation, the lowermost screen being provided with a collecting pan 18 and discharge chute 20, for undersize materials passing through the lowermost screen.
- the compression springs 12 on which the vibrating chamber is mounted may be replaced by rubber bushes or any other resilient assemblies.
- Alternative vibrating means may be provided so long as they impart to materials on the screen a movement causing undersize material to pass through the screen and oversized material to pass to the edge of the screen.
