Reciprocating rotary type caused by oscillator exciting vibration and work.The upper rotation weight of oscillator makes compass screen surface generate plane whirling vibration,
And lower rotation weight then makes compass screen surface generate conical surface rotary vibration, the effect of synergy then makes compass screen surface generate again the vibration of rotation type.
Its oscillation trajectory is a complicated space curve.The curve is projected as a circle in horizontal plane, and being projected as on the vertical plane
One ellipse.Adjust the exciting force of upper and lower rotation weight, thus it is possible to vary amplitude.And the space phase angle of upper and lower weight is adjusted,
It then can change the curve shape of compass screen surface motion profile and change the motion profile of material on compass screen surface.Most of is solid for mud
A kind of mechanical separation equipment of filterability of phase processor, sieve and oscillator composition.The thickness of sieve indicates with mesh, general 50 mesh with
Under be wide-meshed screen, more than 80 mesh be fine screen mesh.Oscillator is an eccentric wheel, rotates under motor drive, sends out screen frame (unit)
Raw vibration.Due to the vibration of screen frame (unit), thicker solid particle is left on compass screen surface when mud flows on compass screen surface, and along inclined-plane from one
End discharge, thinner solid phase particles and slurry fluid pass through sieve pore together and flow to mud pit.
Physics screening process is the granular material group that granular size is different, the single-layer or multi-layer of the uniform cloth hole of multipass
Compass screen surface is divided into the process of several different stages, referred to as sieves.Particle greater than sieve pore stays on compass screen surface, referred to as the sieve of the compass screen surface
Excess, the particle less than sieve pore penetrate sieve pore, the referred to as screenings of the compass screen surface.Actual screening process is: a large amount of granule sizes
