Industrial screening machines

The right size,
a clean cut.

Stainless steel vibratory sieves, tumbler screeners and linear vibrating screens for powders, granules and particulate products. Built to size, tested first on your own material.

Our approach

Every material screens differently

  1. Material arrives

    The same mesh does not behave the same way with a free-flowing powder and a damp granule. Particle shape, density, moisture and temperature change the machine type, the mesh opening and the vibration angle.

  2. The screen separates

    That is why we do not sell machines from a catalogue. We screen your sample on a real machine in our workshop, review the result with you, and only then start production.

  3. The right size comes out

    Every particle that passes the screen passes through our workshop first. You see the result before you buy the machine.

Machines

Three machines, three motions

Circular vibration, slow tumbling or linear travel: we choose the motion that suits your material.

Round Vibratory Sieve
01The most common type for powders and granules

Round Vibratory Sieve

VE-60 · VE-140

Circular body, three-dimensional vibration. Material spirals outward from the centre; fines pass the mesh, oversize reaches the outlet. Stacked screen decks give several fractions from one machine.

Linear Vibrating Screen
03High capacity, multi-fraction separation

Linear Vibrating Screen

Rectangular body, linear vibration. Material enters at the feed end and travels in a straight line to the outlet; short path, fast passage, high tonnage. Connects directly to an existing conveyor line.

How we work

From sample to commissioning

Every machine goes through the same four steps. None of them is skipped.

  1. 01

    Sample

    We learn what you want to separate, at what capacity and to which size, and take your sample into our workshop.

  2. 02

    Workshop test

    We screen the sample on a real machine and change mesh and vibration settings until the result is clear. We share the result with you.

  3. 03

    Built to size

    We build the machine to your existing line, outlet height and capacity. Every product-contact surface is stainless steel.

  4. 04

    On-site commissioning

    We start the machine at your plant and show the operator screen changes and maintenance points. Wear parts such as screen wire, gaskets and springs ship from stock.

Why UNL

Stainless, clean, tool-free

The same care on every product-contact surface: welds are polished and no dead volume is left in the corners.

  • Stainless body

    Every product-contact surface is stainless steel. In food and pharma applications, ease of cleaning is where the design starts.

  • Polished welds

    Weld seams are polished; no ridges or grooves are left to hold product.

  • No dead volume

    No corner is left in the body where material could sit and build up. On a product change, nothing of the previous product remains.

  • Clamped screen decks

    Screen decks come off without tools. A screen change or a clean-down is done in minutes.

  • Wear parts in stock

    Screen wire, gaskets and springs are kept in stock; your line does not wait for parts.
