Yes, vibratory screens can be food grade when they are manufactured using appropriate materials and sanitary construction standards. [Read full answer →]
Material flow is controlled by adjusting the counterweight lead angle on the ItalVibras motor. Changing the lead from 0° to 90° alters the spiral pattern and dwell time.
Epoxy encapsulation provides a secondary seamless layer that eliminates small crevices where bacteria can grow. This is often a requirement for USDA or FDA-regulated HACCP plans to prevent material entrapment during food processing. [Read the FDA Compliance Deep Dive →]
No. Thinner steel and non-standard parts lead to significantly higher downtime and difficulty finding replacement parts. ScreenerKing machines are manufactured in North America, ensuring high-grade materials and structural integrity.
Adjusting the "lead angle" of the bottom motor weight changes how material travels. A 0-degree lead provides fast discharge; a higher lead angle (45 degrees) increases "dwell time" for more thorough sifting of fine powders. [See the Counterweight Adjustment Guide →]
Yes, vibratory screeners can handle wet material, but performance depends on moisture level, particle size, material cohesiveness, and screen configuration. [Read full answer →]
The correct wire diameter for screening depends on your material type, required durability, desired open area, and separation precision. [Read full answer →]
Open area on a vibratory screen refers to the percentage of the screen surface that consists of openings through which material can pass. [Read full answer →]
Mesh size does not directly equal microns, but it can be converted approximately. Mesh size refers to the number of openings per linear inch, while microns measure the actual opening size. [Read full answer →]
To determine the correct mesh size for your material, you need to consider the target particle size, material shape, moisture content, and the desired separation accuracy. Choosing the right size ensures efficient separation, optimal throughput, and minimizes issues like blinding or pegging during operation. [Read full answer →]
The mesh size vibratory screen you need depends on the particle size you want to separate, the shape and condition of the material, and how accurate the separation must be. Mesh size refers to the number of openings per linear inch of screen surface, with higher mesh numbers producing finer separations. [Read full answer →]
Sizing is determined by calculating the screening area required to process your peak flow rate. You must account for 'bed depth'—if the material layer is too thick, fines cannot reach the mesh. [View the Screen Sizing Deep Dive →]
Woven wire screens are made from interlaced metal wires and provide precise particle separation with high open area. Perforated screens are solid metal sheets punched with holes and offer greater durability for heavy or abrasive materials but less separation precision. [Read full answer →]
The most common mesh size used in vibratory screeners is 60 mesh. It provides an effective balance between separation accuracy and production throughput for many industrial powder and bulk material applications. [Read full answer →]
Tensile Bolting Cloth (TBC) uses a thinner wire diameter to provide a higher percentage of open area, maximizing throughput for fine sifting. Mill Grade mesh uses a heavier wire for increased durability and a longer lifespan in abrasive applications. [View the Mesh Sizing Chart →]
We recommend a backing mesh (typically 18 TBC) for any fine mesh applications of 100 mesh or finer. The backing mesh acts as a support structure, preventing the fine wire from sagging or stretching under heavy material loads.
To ensure peak throughput, we require the material's bulk density, moisture level, target micron size, and peak throughput requirements (lbs/hr) to recommend the correct machine diameter and mesh.
To measure a vibratory screener screen, you need to determine the frame diameter (or length and width for rectangular units), screen height, mesh size, and frame style. [Read full answer →]
You can identify your vibratory screener model by locating the manufacturer nameplate, serial number tag, or stamped model identification on the machine frame. [Read full answer →]
A replacement screen will fit your screener if the diameter or dimensions, frame style, mounting method, mesh specifications, and brand compatibility match your machine’s requirements. [Read full answer →]
Replacement screens that fit a SWECO® vibratory screener must match the machine’s exact diameter, frame height, mounting configuration, and mesh specifications. [Read full answer →]
Yes, you can often use a non-OEM (aftermarket) screen on a vibratory screener, provided the replacement screen matches the original equipment specifications for diameter or dimensions, frame construction, mounting method, and mesh configuration. [Read full answer →]
Yes. Our round vibratory screens are precision-engineered to be 100% compatible with industry-standard round screeners from Kason, Sweco, Midwestern, and other major brands. Our screens meet or exceed all OEM fit and tension specifications. [View the Compatibility Deep Dive Page →]
Yes. Our frames are built to industry-standard dimensions, making them fully interchangeable with Sweco, Kason, and other major separators. We offer 304 and 316 stainless steel with polished, sanitary finishes and continuous welds for food and pharmaceutical applications. [View Stainless Steel Frames →]
Yes. Our motors (including our ItalVibras line) are designed for standard compatibility. We offer direct-replacement options for most existing vibratory machines, including explosion-proof and high-capacity models used by North American processing plants. [View Motors →]
A vibratory screen clogs when material blocks the screen openings, preventing proper separation. The most common causes are excessive moisture, fine particle size near the mesh opening, improper mesh selection, insufficient vibration, and material buildup from static or cohesion. [Read full answer →]
Yes. Most vibratory screens must be properly tensioned to function correctly. Proper tension ensures the mesh remains stable under vibration, maintains accurate separation, and prevents premature fatigue or tearing. [Read full answer →]
Vibratory screener screens can last anywhere from a few weeks to over a year, depending on material abrasiveness, mesh size, operating hours, vibration settings, and installation quality. [Read full answer →]
A vibratory screen fails early due to improper installation, incorrect tensioning, excessive vibration stress, material overload, poor mesh selection, or inadequate maintenance. [Read full answer →]
Blinding is resolved through mechanical agitation. ScreenerKing offers Sliders, Balls, and Sandwich Screens that use the machine’s vibration to physically clear the mesh openings. [View Anti-Blinding Troubleshooting Deep Dive →]
Yes. As a custom manufacturer, ScreenerKing can build screens with specific center hole diameters, unique bonding methods (epoxy or heat-seal), and reinforced edges for older or proprietary machines where OEM parts are no longer available. [Explore our Screens →]
We offer Nylon Sliders and Rubber/Silicone Balls. Sliders shear material from the bottom of the mesh to stop "blinding," while balls provide vertical impact to dislodge "pegged" particles, maintaining consistent throughput.
Screens are manufactured by precision-tensioning stainless steel mesh over a high-tensile ring. The mesh is bonded using industrial-grade epoxy or welding to maintain "drum-tight" specs critical for efficient particle separation. [Learn More About Screen Manufacturing →]
With a proper maintenance schedule, a high-quality stainless steel screener can last 20+ years. The primary wear parts are the screens and gaskets, while the motor and frame are designed for decades of service. [Read our Maintenance Guides →]
Our standard lead time is 5 to 7 business days. As a domestic manufacturer with a hub on the East Coast, we maintain a large inventory to ensure fast turnaround for North American facilities, including expedited options.
To minimize expenses, 48" and 60" screens are shipped via LTL freight using specialized pallet stacking. This allows multiple large-diameter screens to be shipped together, significantly reducing the per-unit freight cost. [Read More About Minimizing Freight Expenses →]
You will receive an automated shipping confirmation email with a tracking link (UPS, FedEx, or Freight) once the order departs our facility.
Most units can be commissioned in 4-6 hours. This includes de-crating, positioning, wiring the motor, and calibrating the counterweights to match your specific material bulk density.
Common mistakes include over-greasing motor bearings, running with loose clamp rings, and ignoring worn gaskets. Weekly gasket checks and monthly motor greasing are minimal but vital for preventing downtime.
