Conclusion

1. What Is a Vibrating Screen Quotation?

A Vibrating Screen Quotation is a technical and commercial proposal provided by a screening equipment manufacturer or supplier.

It normally includes information such as:

Vibrating screen model

Machine size

Screening layers

Screen mesh

Construction material

Motor and drive configuration

Screening capacity

Material handling requirements

Sealing requirements

Cleaning requirements

Customized components

Spare parts

Delivery and installation requirements

Equipment price

For powder screening applications, the quotation should be based on the actual material and screening requirements rather than only the desired machine size.

For example, a food manufacturer screening flour may require a different screening solution from a chemical manufacturer screening fertilizer powder or a metallurgical company screening metal powder.

Therefore, providing detailed application information before requesting a quotation can help the manufacturer select a more appropriate screening machine.

2. What Information Affects a Vibrating Screen Quotation?

Several technical factors can affect the configuration and quotation of a vibrating screen.

kg/h

tons/h

Batch quantity

Continuous processing requirement

Capacity is not determined by machine size alone. Material characteristics, feed conditions, screen mesh, number of layers and required separation can all affect actual screening performance.

Therefore, the quotation should be based on the complete application rather than a machine size selected independently.

2.4 Screen Mesh

Screen mesh is directly related to the required separation size.

A quotation may change depending on:

Mesh size

Aperture

Screen material

Number of screen layers

Screen surface area

Fine screening requirements

Different materials may require different screen mesh configurations.

For example, food powders and chemical powders may require fine mesh screening, while granular materials may use a comparatively larger opening.

The required mesh should therefore be specified together with the target particle size.

2.5 Number of Screening Layers

A vibrating screen can be configured with different numbers of screening layers according to the required classification.

A single-layer machine may be sufficient when the objective is simply to remove oversized particles.

Multi-layer screening can be considered when several particle size fractions need to be separated in one screening process.

The number of layers can affect:

Machine configuration

Screen area

Screening stages

Product outlets

Equipment dimensions

Overall quotation

2.6 Machine Size

The required machine size depends on factors such as:

Material characteristics

Required capacity

Screen mesh

Number of layers

Common considerations include:

Carbon steel

Stainless steel

Stainless steel for material-contact parts

Customized material configurations

Stainless steel construction may be selected when corrosion resistance, hygiene, cleaning and material compatibility are important.

For pharmaceutical and food processing applications, the customer may also require an enclosed structure and smooth, easy-to-clean material-contact surfaces.

2.8 Cleaning Requirements

Cleaning requirements should be discussed before the quotation is prepared.

This is particularly important for:

Food powders

Pharmaceutical powders

Fine chemical powders

Materials requiring frequent product changeover

The quotation may need to include suitable screen structures, access arrangements and cleaning-related configurations according to the customer's production process.

2.9 Sealing Requirements

Enclosed screening equipment can help reduce dust leakage during powder processing.

Sealing requirements may depend on:

Material properties

Production environment

Dust control requirements
