Multi Deck Vibrating Sieve

A Multi Deck Vibrating Sieve is designed to separate powders and granular materials into multiple particle-size fractions in one screening process. By using different mesh sizes on multiple decks, the machine can perform particle size separation, grading, and impurity removal efficiently.

Dahan supplies multi-deck configurations with 1-6 decks, with the screen mesh, screening area, machine material, and outlet arrangement selected according to the material, required capacity, and target particle sizes.A Multi Deck Vibrating Screen, also referred to as a multi-deck vibrating sieve, is suitable for applications requiring several particle-size fractions from a single feed stream.

Actual capacity depends on material characteristics, moisture, particle-size distribution, mesh opening, feed rate, deck configuration, and machine model.

What Is a Multi Deck Vibrating Sieve?

A Multi Deck Vibrating Sieve is a vibrating screening machine equipped with two or more screen decks arranged vertically. Each deck can use a different mesh size to separate material according to particle size.Material enters the upper deck and moves across the vibrating screen. Larger particles remain on the upper screen, while smaller particles pass through to lower decks for further classification.

This multi-layer arrangement allows several particle-size fractions to be produced from one feed material without requiring multiple separate screening machines.For example, a two-deck configuration can normally produce three fractions, while a three-deck configuration can produce four fractions, depending on the mesh arrangement and required separation sizes.

How Does a Multi Deck Vibrating Sieve Work?

The vibration motors generate controlled vibration of the screen box, causing material to move across the screening surfaces.

Feed Material enters the upper screening deck.

Separation Larger particles remain while smaller particles pass through.

Classification Lower decks provide further particle-size separation.

Discharge Each fraction exits through its corresponding outlet.

The final screening result depends on material characteristics, screen mesh, vibration conditions, feed rate, and required particle-size separation.For materials that are prone to screen blocking or blinding, a bouncing ball screen-cleaning system can be used to help maintain screening performance.

Multi Deck Configuration

The required number of decks mainly depends on the number of particle-size separation points needed.

Number of Decks	Possible Fractions
1	2
2	3
3	4
4	5
5	6
6	Up to 7

The actual number of usable fractions depends on the selected mesh arrangement and target particle sizes.

Technical Parameters

Dahan offers different machine sizes according to the required screening area and processing capacity.

Model	Screen Size	Deck Options	Reference Capacity
DZSF520	500 x 2000 mm	1-3	Up to 5 t/h
DZSF525	500 x 2500 mm	1-6	Up to 15 t/h
DZSF1020	1000 x 2000 mm	1-6	Up to 20 t/h
DZSF1025	1000 x 2500 mm	1-3	Up to 15 t/h
DZSF1030	1000 x 3000 mm	1-3	Up to 20 t/h
DZSF1224	1200 x 2400 mm	1-3	Up to 23 t/h

These are reference specifications. The suitable model should be confirmed according to the material, throughput, feed particle size, target separation sizes, and installation requirements.

Applications

 Application Example

Multi Deck Vibrating Sieve can be used for a wide range of dry powders and granular materials, including:

• Food: flour, sugar, starch, grain and seeds
• Chemical: resin powder, chemical powders and plastic particles
• Fertilizer: granular and powdered fertilizer
• Minerals: quartz sand, iron ore powder, kaolin and other mineral materials
• Industrial materials: activated carbon, sawdust and other granular products

The machine configuration should be selected according to the actual material characteristics and screening requirements.

A multi-deck configuration can be used when one feed material needs to be separated into several particle-size fractions.

Requirement	Example
Material	Powder or granular material
Capacity	Customer specified
Decks	2-4
Mesh	Selected according to target sizes
Output	Multiple particle-size fractions

For a real project, the deck number, screen mesh, machine size, and capacity should be confirmed according to the customer's actual material and screening requirements.

How to Choose a Multi Deck Vibrating Sieve？

The correct machine should be selected according to the actual screening process rather than the number of decks alone.

Material: Provide the material name and characteristics, including density, moisture, flowability, and particle shape.

Capacity: Specify the required processing rate in kg/h or t/h.

Feed Particle Size: Provide the approximate particle-size range of the incoming material.

Target Separation Sizes: Specify the required particle-size cuts. This determines the mesh openings required on different decks.

Number of Fractions: The required number of final fractions is an important factor in determining the number of decks.

Screen Mesh: Different mesh sizes can be installed on individual decks to achieve different particle-size classifications.

Machine Material: Carbon steel can be used for many general industrial applications. SS304 can be selected when greater corrosion resistance or cleaner product-contact surfaces are required.

For an accurate recommendation, provide your material, capacity, feed particle size, target particle sizes, and required number of fractions.
