Screening into several fractions at once: the vibrating motor drives the material forward in a straight line while divergent bars loosen it so the deck is never covered.

A waste vibrating screen does the simplest and most frequently needed job in a sorting line: it splits material by size. The vibrating motor gives the screening surface a linear motion, upward and forward. Material hops along the deck, small particles fall through the apertures, larger ones advance and exit at the end.
The detail that separates it from just any screen is the divergent bars. They loosen the material as it beats against the deck and stop the decks being covered, that is the situation where a compact layer of material sits on the screen and nothing passes any more. See the full range of waste sorting equipment and how the machines combine.
• Several fractions in one pass, with two or three stacked decks, a vibrating screen splits material into three or four fractions at once, which would otherwise take several machines.
• Adjustable amplitude and frequency, the vibration intensity is matched to the material, so the same machine screens heavy rubble and light packaging waste equally well.
• Divergent bars against deck covering, the material is constantly loosened, so the layer does not compact on the deck and the surface stays active along its whole length.
• Low energy consumption, it works by inertia rather than continuous force, which makes it one of the most energy-efficient machines in the whole line.
• Apertures to order, mesh or grid, with the opening specified to suit the fractions you want to produce.
• Simple construction, few moving parts, therefore high reliability and predictable maintenance.

Throughput depends on the number of decks, the chosen apertures and material density, so it is set at configuration. Screen apertures are specified according to the fractions you are after.
• Waste sorting plants, size grading at any point in the line, including the final check on the fractions.
• Construction waste, screening sand, gravel and crushed stone for recycled aggregate production.
• Biomass, grading wood chip into fractions, for boilers or for pellet production.
• Compost and fertiliser, screening the finished product for uniform particle size.
• Industrial waste, size separation of production offcuts before recovery.
Material enters the screening surface and the vibrating motor drives the screen box in a linear motion, oriented upward and forward. Each impulse lifts the material slightly off the deck and pushes it toward the discharge end. While the material is detached from the surface, particles are free to reorient, and those smaller than the aperture fall through it under gravity. Divergent bars mounted above the surface loosen the material layer and stop it compacting, which would otherwise block screening. With several stacked decks, apertures decreasing from top to bottom, the flow is split into as many fractions. Amplitude is set from the vibrating motor counterweights and frequency from the drive, and together they determine how aggressively the material is treated.
The first criterion is how many fractions you want. One deck gives two fractions, two decks give three, three decks give four. The second is width, chosen from line throughput. The third, and the one most often forgotten, is material moisture. A classic vibrating screen performs excellently on dry or moderately damp material, but on fresh, saturated household waste it blinds. In that case you need a flip flow screen or a star screen. For rubble, aggregates, biomass and finished compost, a vibrating screen is the right and most economical choice.
How many fractions can I get?
As many decks as the machine has, plus one. One deck gives two fractions, two decks give three, three decks give four. Each deck has its own aperture, decreasing from top to bottom, and each fraction is collected separately. The configuration is set once you tell us which fractions you need.
Does it work on wet household waste?
Only up to a point. A vibrating screen is a very good solution for dry or moderately damp material, but on fresh household waste with food residue the rigid deck blinds. For that flow we recommend a flip flow screen or a star screen, both designed to be self-cleaning. We will tell you honestly which one fits, we do not sell the wrong machine.
What do the amplitude and frequency settings do?
Amplitude is how far the deck travels on each oscillation, frequency is how fast it oscillates. Together they determine how hard the material is thrown. Heavy material wants large amplitude and lower frequency, light material the opposite. The adjustment lets the same machine serve different flows.
What are the divergent bars for?
They stop the material forming a compact layer on the deck. Without them, at high throughput, the material on top presses down on what is below, small particles never reach the apertures and screening effectively stops even though the machine is running. The bars keep the layer loose and the surface active.
Is the equipment supplied new?
Yes. We supply new units only, made to order for your application, with complete technical documentation.
What maintenance does it need?
Checking the condition and fixing of the screens, inspecting the bearings and the vibrating motor, checking the elastic suspension elements and the tightness of the bolts, which can loosen from the vibration. The screens are wear parts and are replaced periodically.

Six technology directions we integrate turnkey: from plug & play IIoT sensors, to cobots, predictive maintenance, optical inspection, MES connectivity and custom industrial software.
See in real time how much each machine produces and how long it sits idle. We fit sensors on any equipment, new or old, and within a few hours you have the OEE dashboard on your phone. No complex wiring, no production downtime. The first concrete step toward digitalization, with ROI visible from the very first month.
Solve your labor shortage without tripling your costs. The cobot works safely alongside your people (palletizing, feeding the CNC, welding) while you recover the investment in 12-18 months. Prices 30-40% below European distributors, with installation and programming included from us.
Stop waiting for things to break. Our algorithms analyze sensor data and tell you exactly which part will fail and when, and we bring it to your production line before the breakdown. Zero unplanned downtime, zero contractual penalties, complete operational peace of mind.
Eliminate defects before they reach the customer. Our cameras inspect every part at speeds no operator can match, detecting sub-millimeter defects. They mount onto your existing line, with no modifications. Ideal if you produce for export and have strict quality clauses.
Connect your machines to your office, regardless of brand or age. Our gateway automatically translates the data from any machine into your ERP's format: no manual entry, no paper forms, no human error. The manager sees production live, the operator receives digital instructions.
