It is a rotary vibrating screen designed to screen, separate, sort and sieve powders and granular materials in food processing — including sea salt, grains, flour and similar materials — for grading and removing oversized particles or foreign matter.
The machine is available in carbon steel or stainless steel. For food-grade use and better corrosion resistance (especially with salt), 304 or 316 stainless steel is recommended.
Capacity ranges from about 10 kg/hour up to 10 tons/hour depending on model, diameter, mesh size and material characteristics. Final capacity depends on particle size, bulk density and required cut size.
Diameters are available from 400 mm to 2000 mm, with customizable overall dimensions (L×W×H). Screening layers can be configured from 1 to 5 decks to meet different separation requirements.
The machine operates with motors compatible with 50 Hz or 60 Hz supply. The motor provides a vertical excitation source with eccentric weights to generate horizontal, vertical and inclined motion; power rating and rotation speed should be specified at order to match local supply and application.
There are two cleaning options: mechanical bouncing balls (placed under the screen to dislodge blinding particles) and an ultrasonic cleaning system that transmits high-frequency vibrations to keep mesh clear. Bouncing balls are simple and cost-effective; ultrasonic is better for very fine or sticky materials.
The rotary vibrating screen features a quick-change design — typical screen changeover takes about 3–5 minutes, depending on operator experience and configuration.
The machine is CE certified and the manufacturer holds ISO9001:2008 certification. A 1-year warranty is provided for the unit under normal operating conditions.
Yes — when specified in stainless steel (preferably 316 for higher chloride environments) the machine is suitable for sea salt and other corrosive products. Carbon steel models are less resistant to corrosion.
Regular maintenance includes inspecting and replacing worn screen cloths, checking and tightening fasteners, lubricating bearings per schedule, verifying motor and eccentric weights, and cleaning the unit after production. Follow the manufacturer's maintenance manual for specific intervals.
Selection depends on target particle size, allowable oversize, throughput and material properties (moisture, abrasiveness). Finer cut sizes require finer mesh and may reduce throughput; multiple layers can separate several size fractions. Provide sample material and target specs to the supplier for an optimized recommendation.
The machine requires a level, rigid floor and appropriate electrical supply (50/60 Hz). Lighter models (~100 kg) may not need heavy anchoring but should be placed on a stable base and may be bolted or mounted to a frame depending on vibration isolation and plant layout. Consult installation instructions for anchoring and isolation pad recommendations.
The rotary vibrating screen is designed for low noise operation and an enclosed structure reduces dust. Proper installation with isolation mounts further minimizes transmitted vibration, making it appropriate for indoor food processing areas when installed per guidelines.
Yes — customizable dimensions, inlet/outlet orientations and mounting options allow integration into conveyors, feeders and downstream equipment. Controls can be adapted to PLCs or factory automation systems on request.
Contact the supplier with your material details, desired capacity, mesh size, preferred construction material and any dimensional constraints. Lead time depends on customization but typically ranges from a few weeks to a couple of months. Spare parts and service plans are available — ask the supplier to include recommended spare screens, bearings and cleaning system components in the quote.
