Vibro Screens for Paper & Pulp Industry
Creative Vibro Screens provides vibro screening solutions for paper and pulp applications where efficient separation, filtration, and recovery of fibres or process materials are required.
Our vibro screens can be used for a range of paper and pulp process applications, including Size Press, PAC and alum, coating powders, backwater screening, and fibre recovery from water.
The right screening configuration depends on the material characteristics, process conditions, required separation, and throughput of the application.
Paper & Pulp Screening Applications
Paper and pulp manufacturing involves different liquid, powder, fibre, and chemical process streams. Screening these materials can help remove unwanted particles, maintain process consistency, and recover valuable fibres or materials from process water.
Creative Vibro Screens can be used for applications including:
-
Size Press screening
-
PAC and alum screening
-
Coating powder screening
-
Backwater screening
-
Fibre recovery from water
Each application has different screening requirements, so the screen type, mesh, configuration, and construction should be selected according to the process.
Vibro Screens for Size Press Applications
Size Press is an important stage in paper manufacturing where sizing materials are applied to the paper web. The process material may require screening to help remove unwanted particles or agglomerates before application.
A suitable vibro screen can help provide controlled screening of the Size Press material, supporting consistent process conditions and helping prevent unwanted material from entering subsequent stages.
The appropriate screening arrangement should be determined based on the properties of the Size Press solution and the required level of filtration.
Vibro Screens for PAC and Alum
PAC (Poly Aluminium Chloride) and alum are used in water and process treatment applications associated with paper manufacturing.
Where these materials require screening, a vibro screen can provide controlled separation of unwanted particles or agglomerated material.
Screen selection should take into account the material condition, particle characteristics, required separation, and whether the application involves dry material or a liquid/process stream.
Vibro Screens for Coating Powders
Coating materials are used in paper manufacturing to achieve specific surface and printability characteristics.
Coating powders may require screening to help remove lumps, oversized particles, or unwanted foreign material before further processing or use.
A vibro screen can provide controlled powder screening through the selected screening mesh, helping maintain consistency in the material entering the next stage.
The suitable screening configuration depends on powder characteristics, required separation, feed rate, and process requirements.
Vibro Screens for Backwater Screening
Backwater is generated during paper manufacturing and can contain water, fibres, fillers, and other suspended material.
Screening backwater can help separate fibre and solid material from the water stream, depending on the required process objective.
A properly selected vibro screen can be incorporated into a backwater screening system to support separation and recovery requirements.
The actual screening arrangement should be selected based on the concentration of solids, flow characteristics, fibre content, and required separation.
Fibre Recovery from Water
Fibre recovery is an important consideration wherever useful fibres are present in process water.
Vibro screening can be used to separate fibre-containing solids from water in suitable applications. This can help recover usable fibre while reducing the amount of fibre carried away with the water stream.
The effectiveness of fibre recovery depends on factors such as fibre characteristics, concentration, water flow, screen opening, and the overall process arrangement.
Why Use Vibro Screens in Paper & Pulp Processing?
A properly selected vibro screen can provide practical benefits in paper and pulp processing, including:
-
Controlled Screening
Vibratory screening provides controlled separation through a selected screening surface, allowing the machine to be matched to the process requirement.
-
Improved Process Consistency
Screening can help remove unwanted particles, agglomerates, or oversized material from suitable process streams before downstream processing.
-
Fibre Recovery
In appropriate applications, screening can help recover fibres from water and process streams, supporting better utilization of valuable material.
-
Process Protection
Removing unwanted or oversized material before subsequent processing can help reduce the risk of undesirable material entering downstream equipment.
-
Application Flexibility
Vibro screens can be evaluated for different paper and pulp materials, including powders, process liquids, water containing fibres, and other suitable process streams.
Selecting a Vibro Screen for Paper & Pulp Applications
The correct vibro screen should be selected according to the actual process rather than simply by machine size.
Important information for selection can include:
-
Material or process stream to be screened
-
Whether the application is wet or dry
-
Feed rate or flow rate
-
Fibre or solids concentration
-
Particle size and characteristics
-
Required separation or filtration level
-
Material temperature, where relevant
-
Number of screening stages
-
Space available for installation
-
Material of construction requirements
-
Existing process equipment
-
Cleaning and maintenance requirements
Providing this information allows the screening system to be considered according to the actual application.
Paper & Pulp Screening Solutions from Creative Vibro Screens
Creative Vibro Screens focuses on industrial screening equipment for applications where controlled separation and material handling are important.
For paper and pulp processing, our vibro screens can be considered for Size Press, PAC and alum, coating powders, backwater, and fibre recovery from water.
Rather than relying on a standard screening arrangement for every application, the equipment should be evaluated according to the characteristics of the material and the requirements of the process.
