Screening Stations
Maskin Mekano is a market leader in mobile, high-performance screening. Our screening stations impress with thoughtful design, robust construction, and user-friendly solutions.
The foundation of our success lies in Maskin Mekano’s own performance screens. The STE-screens concept uniquely combines high capacity with top-quality output. All our screening stations are electric-powered and consume very little fuel, making the investment highly cost-effective.
Electric drive
Maskin Mekano has been working with electric drive for over 20 years – we have extensive experience in this field, and our solutions and components are well-tested!
STE-Screen
Sharp and consistent screening curves Fine screening presents special demands on screening equipment. No matter how well you crush and cube, the screen can still hinder the screening result.
Vibro block
Keep the power where it’s needed STE screens are supported both in the frame and in the screening box (4-layered/forced drive), ensuring that they maintain the same speed and impact regardless of the load.
Frequently asked questions about screening
Here are some of the most frequently asked questions we receive about screening. If you can’t find the answer to your question, feel free to contact us!
What does a screening plant actually do?
The screening plant determines which products are actually created. It separates the material into defined particle sizes, and how cleanly it separates the fractions affects both product quality and the value of what you sell. Plant performance is often limited by the screen, not the crusher.
Is it enough to compare screening area and capacity when choosing a screen?
No. Two screens with the same screening area can give completely different results. What matters is how the screen box moves, how long the material stays on the deck, how well it is loosened and how evenly it is fed. Judge a screen by the clean fractions it produces in your material, not just by tonnes per hour.
Why do results get worse when you push the feed rate?
A higher feed rate gives the material less time on the screen deck. The fines never reach the apertures and end up in the oversize. An economical screen runs where capacity and quality are in balance, because high hourly output is worthless if the products fail to meet requirements.
What is the STE principle with an 11° inclination and 12 mm stroke?
The shallow 11° inclination gives the material more time on the deck, so every particle has a better chance of reaching the right mesh. The large 12 mm stroke loosens the material continuously and breaks up agglomerates without rushing it across the deck. The combination of the two gives high screening accuracy, especially in moist and sticky material.
Why a four-bearing screen box?
The four-bearing forced drive guides the screen box movement precisely, so the movement stays the same regardless of how much or what kind of material is on the deck. That gives consistent screening quality. It also reduces changing loads on bearings, shafts and welds, which means longer service intervals and higher availability.
What is the Vibroblock?
The Vibroblock separates the vibrating screen box from the load-bearing frame. The vibrations then work in the screen box, where they are needed, instead of loading the chassis. The result is less material fatigue, fewer cracks, smoother operation and lower maintenance costs over the machine’s life.
Can moist and sticky material be dry screened, or does it have to be washed?
Often it can be dry screened. Moist material screens poorly mainly because the particles do not separate from each other, not just because it is wet. With the right screen box movement, much material that is traditionally washed can be screened dry. Material with high clay content, severe adhesion or the highest purity requirements might still need water. Learn more about wet screening under our recycling range.
What do you gain by avoiding wet processing?
You avoid water consumption, sludge handling, pumps, thickeners, filter presses and permits. Investment, operating cost, energy demand and space requirements all fall. Above all, the whole process becomes simpler, and simpler processes usually run more reliably.
How do you know how many decks and how much screening area you need?
It depends on the material and the final products you want. A material analysis shows particle-size distribution, moisture and variation, and from that the screening area, number of decks, cut sizes and screen media are defined.
