Tumbler Screening Machine VAN

Vibrowest tumbler screening machine is used for control screening, fractionating and dust removal in dry, powdered and granular products.

The tumbler screener has a three-dimensional movement similar to the simple hand screening of the “gold washing pan”. This tumbline action yeilds better efficiency and a higher specific screen load as compared to vibration systems.


The tumbler screening machine VAN is used in all sectors of application and has stable screen motion even under full load. The tumbling sifter VAN is particularly suitable for high feed rates and multi deck separations of fine, lightweight products which are difficult to screen. 

The tumbling movements easy regulation and adjustment with low frequency vibrations guarantee the following advantages:

- No particle destruction in sensitive products;

- Precise control of product movement and time tranversing the screen;

- Screening efficienies up to 99%

- Consistant product quality.

Tumbler screening machine features and benefits

Easy installation and commisioning. The ability to separate particles in 1 to 6 sizes with up to 5 screen decks incorporated in one Vibrowest separator.

Standard model range in diameter size from 1.200 mm to 2.600 mm

The screens are easy and fast to change and can be equipped with various cleaning system as balls and the innovative ultrasonic cleaning system

The tumbler screening machine VAN can be specified with carbon steel, stainless steel AISI 304 or stainless steel AISI 316 construction.

On request: ATEX certification, FDA IQ-OQ procedure, GMP can be provided.

All product contact areas can be polished to be in accordance with sanitary standards.

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.
