Circular vibrating sieve MR


Circular vibrating sieve MR

MR circular vibrating sieve segregates solids from liquids or dry material into various particle sizes ranging from 51 mm to 0,033 mm  (400 mesh).

Easy to install, the circular screener MR, can be equipped to separate up to 5 sizes with up to 4 screen decks incorporated in one Vibrowest sieve.

Standard models range in size from 440 mm to 1800 mm

Screens are easy and fast to change and can be equipped with various cleaning system as: balls, kleeners, starbrush, CIP and the innovative ultrasonic cleaning system

The circular vibrating sieve is avaiable constructed of carbon steel, stainless steel AISI 304 or stainless steel AISI 316.

On request: ATEX certification, FDA IQ-OQ procedure, GMP avaialable.

All product contact areas can be polished to be in accordance with Sanitary Standards.


The vibration is develop in both the horizontal and in the vertical plane and can be adjusted in both directions

Vibration is accomplished by eccentric weights positioned on fly wheels on the upper and lower ends of the motion generator shaft.

The upper fly wheel creates vibration in the horizontal plane, which moves the material from the center to the outer perimeter of the screen. The lower fly wheel creates vibration in the vertical as well as tangential plane producing a highly efficient sieving action.

Adjusting the counterweights on the fly wheel is rapid and tool free. This adjustment allows modifing the vibration pattern to find the best sieving action for a particular product.

The ability to adjust the vibration pattern results in the high screening efficiency both with liquid and solid products.

Circular vibrating sieve MR advantages

Vibrowests 45 years of experience in sieving technology, innovative and efficient design has brought  Vibrowest Sieves to the highest levels of efficiency and reliability. 

The circular vibrating sieve MR can be modified and adapted to suit a wide variety of customer requirements.

Deblinding systems

Screen Deblinding systems

Vibrowest offers a rubber ball and kleener deblinding system. This system is comprised of a working mesh ring on top, and a coarser mesh ring (support screen) or perforated plate positioned to the bottom. The balls or sliders are placed in-between the top meshring and bottom ring or plate. This sliders and balls, bounce off of the support screen and tap the top screen, dislodging particles or fibers that tend to blind the screen and reduce screening area.

Vibrowest elastomeric ball and kleener Anti-Blinding device utilizes the inertial vibration of the screen and the bouncing elastomeric balls or sliders to minimizes screen blinding.

By reducing the amount of near-size particles lodged in the openings of the wire mesh (blinding), the Vibrowest Anti-Blinding device improves dry sizing and liquid/solid separation, so the seive operates at maximum efficiency.

Vibrowest cleaning system can be provided with all grades of stainless steel, nylon and polyester meshes.

Kleener anti-blinding device

The Kleener anti-blinding device consists of a working mesh ring on top, and a perforated plate on the bottom with plastic rings placed in-between

The vibration of the screener allows plastic rings to move continuously across a perforated stainless steel plate, shearing fibers and scraping away gummy materials. 

Kleeners are effective at preventing fibrous, stringy and sticky materials from blinding the screen.

Elastomeric balls anti-blinding device

The elastomeric ball anti-blinding device consists of a working mesh ring on top, and a coarser mesh ring (support screen) on the bottom with captive elastomeric balls placed in-between.

When the sieve vibrates the elastomeric balls bounce against the upper "operating" screen and the lower support screen dislodging near-size particles lodged in the apertures of the upper screen.


Cleaning system "STARBRUSH" is a system made by a stainless steel triangle with 6 or more brushes which thanks to the vibration of the machine, rotate and keep the mesh clean and efficient.
It is particularly suitable for agglomerated  greasy powders.
