What is a 450 Vibrating Filter Screen
A 450 Vibrating Filter Screen is a compact circular screening and filtration unit (typically 450 mm diameter) designed for efficient processing of liquids and fine powders.the 450 vibrating screen works better for liquid sifter than standard rotary vibrating screens.Widely used in food, chemical, and pharmaceutical industries, it is valued for its high efficiency, easy operation, quick cleaning, and space-saving design.
Working Principle
The 450 vibrating filter screen uses a vertical vibration motor to generate three-dimensional motion (horizontal, vertical, and radial). This motion spreads material evenly across the mesh and drives it outward for continuous processing.
- Fine particles or liquid pass through the mesh quickly
- Oversized material remains on the surface and is discharged automatically
- Continuous vibration helps reduce clogging and keeps the flow stable
Proper selection of mesh size and feeding rate ensures the best performance in actual production.
Parts Of a 450 Vibrating Filter Screen
- Screen Frame & Mesh System
Made of high-strength stainless steel, the precision-welded frame ensures structural stability, while the high-tension mesh provides smooth surface contact and efficient fine particle separation. - Vibrating Motor Unit
The high-performance vibration motor delivers a stable and uniform excitation force, ensuring consistent material movement and improved screening efficiency. - Damping & Support Structure
Equipped with durable damping springs and a reinforced base, it effectively reduces vibration impact, lowers noise, and enhances overall operational stability. - Inlet & Outlet Assembly
Optimized feed and discharge design ensures smooth material flow, minimizes blockage risk, and supports continuous and efficient production.

Cases
The standard mesh size for filter screens is 400 mesh at the finest; custom mesh sizes can be designed. Depending on the material being screened, the screening capacity ranges from 400 to 1,200 kg/hour. Below is a table showing the screening performance and capacity for some common materials:
| Material | Mesh Size | Production Rate |
| Flour | 30 mesh | 700 kg/h |
| Fruit Juice | 40–80 mesh | 6–10 m³/h |
| Coatings | 325 mesh | 1200 L/h |
| Pigments | 100–200 mesh | 500 kg/h |
| Lime (Pulp & Juice Separation) | 100 mesh | 5 t/h |
| Paint / Varnish | 450 mesh | 800 kg/h |
| Buckwheat | 10 mesh | 800 kg/h |
Custom 450 Vibrating Filter Screen Options
Trolley Base
Easy to move, adapts to frequent changes in screening locations, and allows for quick setup and takedown.
Raised Base
Matches the height of the feeding equipment to prevent material spillage caused by excessive height differences between the screen surface and the feeding equipment.
Open Discharge Port (Standard Discharge Port)
Ideal for filtering materials with good flowability and minimal impurities, ensuring fast discharge;
Valve-Equipped Discharge Port
Features a closable valve, suitable for viscous or pseudo-agglomerated materials with poor flowability that are difficult to screen. Closing the valve extends the material’s dwell time on the screen, improving screening accuracy.
Pipe-Type Discharge Port
Designed for liquids prone to splashing or extremely light, highly free-flowing powder materials, reducing splashing and scattering.
Other designs can be customized to meet specific filtration requirements, such as adding a magnetic separator, dust collector, observation window cover, special materials, special motors, or machine colors. Configuration based on your application.
