450 Stainless Steel Vibrating Filter Screen
The JR-450 Ultra-Quiet Screening and Filtering Machine, also known as the 450 Stainless Steel Vibrating Filter Screen, utilizes a new, specialized power generator. Designed by Jiarui’s technical engineers to facilitate user mobility, it is a high-efficiency, low-noise, compact vibrating screening and filtering machine; It can filter 1,200 liters per hour of 325-mesh spray paint with a specific gravity of 1.1, screen 700 kilograms of flour per hour using a 30-mesh screen, and filter 1.5 cubic meters per hour of 250-mesh interior wall paint.
Introduction
The 450 stainless steel vibrating filter screen refers to a single-layer filtering and screening equipment with 450mm diameter, which is usually used to filter, screen, or separate solid particles or liquid substances. It is suitable for the screening range of 0.038 to 3 mm. The equipment has the advantages of low noise, high efficiency, small size, and easy to move, and is an ideal small screening and filtering equipment. According to different needs, the machine body can be made of 304/316 all-stainless steel, or a combination of stainless steel and carbon steel (the base is carbon steel, which is more economical).
Working Principle of 450 Vibrating Filter Screen
The 450 Series Vibrating Filter is a compact, high-efficiency centrifugal sifter designed for liquid filtration and powder grading. Its operation is centered on the conversion of mechanical energy into a specialized multi-dimensional vibration.
1. The Power Source: Vertical Vibration Motor
At the heart of the machine is a high-speed Vertical Vibration Motor. The motor is equipped with Eccentric Weights (unbalanced hammers) installed at both the top and bottom of the motor shaft.
2. Multi-Dimensional Motion Control
As the motor rotates, the centrifugal force generated by the eccentric weights creates a 3D Motion—a combination of horizontal, vertical, and inclined movements.
- Horizontal Action: Moves the material from the center of the mesh toward the periphery.
- Vertical Action: Throws the material upward to prevent the mesh from clogging (blinding).
- Inclined Action: Controls the speed and direction of the material flow across the screen.
3. The Filtration Process
- Feeding: The slurry or powder is fed onto the center of the mesh.
- Screening: The 3,000-RPM high-frequency vibration breaks the surface tension of liquids, forcing the “undersized” material through the mesh.
- Discharge: Particles larger than the mesh size (impurities) are spiraled outward and ejected through the Upper Discharge Outlet, while the filtered liquid flows out through the Lower Outlet.
Features
- High-Frequency Filtration (Professional Efficiency)
- Feature: Equipped with a high-speed 3,000 RPM vibration motor.
- Advantage: The high-frequency, low-amplitude vibration effectively breaks the surface tension and viscosity of liquids. It is specifically designed for high-density slurries, ensuring rapid penetration through the mesh.
- Compact & Portable Design (Space Optimization)
- Feature: Minimal footprint with a diameter of only 450mm.
- Advantage: Its lightweight and compact structure allows for easy relocation by a single person. It is an ideal solution for laboratories, pilot plants, or production lines where space is a premium.
- Ultra-Quiet Operation (User Comfort)
- Feature: Advanced mechanical balancing and shock-absorbing springs.
- Advantage: Operates at a noise level below 50 decibels. This ensures a comfortable working environment without the disruptive noise common in larger industrial screening equipment.
- Superior Material & Hygiene (Compliance)
- Feature: Constructed from high-quality SUS304 or SUS316L stainless steel.
- Advantage: The mirror-polished surface and “no-dead-corner” design prevent material accumulation. It meets strict food-grade and pharmaceutical hygiene standards, ensuring zero cross-contamination.
- Quick-Release Mechanism (Operational Efficiency)
- Feature: Unique screen frame design (V-type or Bolt-less structure).
- Advantage: Allows for a complete mesh change within 3 minutes. This minimizes downtime and simplifies maintenance for operators without the need for specialized tools.
- Anti-Splash & Sealed Design (Safety)
- Feature: Integrated heightened frame (flange) and high-quality seals.
- Advantage: Prevents liquid splashing and dust emission during high-speed operation, keeping the workspace clean and protecting the integrity of the material.
