Product Overview
Serving as a high-efficiency vertical screening unit, the inline vibrating sieve is professionally optimized for uninterrupted, large-scale material handling operations. It utilizes horizontally mounted vibrators as the excitation source, producing multi-dimensional oscillating force that facilitates uniform material spreading and rapid particle separation on the screening surface.
This screening unit abandons the conventional structural design of round vibrating sieves. Its straight-through vertical layout enables fine finished materials to pass through the mesh and discharge downward smoothly, whereas coarse particles and unwanted contaminants are expelled via the lateral discharge opening. This innovative structural optimization greatly boosts overall processing efficiency and shortens the entire material screening cycle.
Boasting a slim, low-height body and fully enclosed dust-tight structure, the equipment supports tool-free disassembly and thorough cleaning with minimal maintenance effort. Its practical production efficiency is 2–5 times that of conventional rotary screening devices. Suited for processing powder, granular and slurry materials, it serves as a premium continuous screening solution for food production, fine chemical processing, pharmaceutical manufacturing and advanced new material industries.
Core Advantages
✅ Suitable for high-static, superfine, agglomeration-prone and light hard-to-sieve powders, thoroughly solving screen blocking and material adhesion problems
✅ No bouncing balls required for auxiliary sieving, eliminating secondary pollution of powder and ensuring material purity
✅ Stable mesh size to maintain accurate sieving precision for long-term operation
✅ Break down adhered and agglomerated materials to reduce residues on the screen surface
✅ Greatly reduce or even eliminate manual screen cleaning procedures to save labor hours
✅ Cut down repeated sieving times and improve overall sieving efficiency
✅ 37kHz high-frequency ultrasonic micro-vibration keeps materials suspended during sieving, ideal for high-quality fine powder processing
Working Principle
The ultrasonic vibrating screen integrates an ultrasonic generator with a rotary vibrating screen. Besides the original three-dimensional vibration of the sieve machine, it adds ultrasonic vibration on the screen surface, which effectively handles hard-to-sieve materials such as highly static, superfine, strongly adsorptive, easy-to-agglomerate and lightweight materials. It solves various sieving challenges and delivers superior performance.
Its operating principle: convert 220V/50Hz or 110V/60Hz electric power into 37kHz high-frequency electric energy. The ultrasonic vibrator mounted on the screen frame converts high-frequency electric energy into mechanical energy, generating invisible ultrasonic vibration on the screen surface. Materials on the screen stay suspended, suppressing blocking factors including adhesion, friction and material settlement. It is especially suitable for manufacturers processing high-quality fine powder.

FAQ
Q1: What are the core advantages of ultrasonic vibrating screen over ordinary rotary vibrating sieve?
A: Equipped with a 33kHz high-frequency ultrasonic anti-blocking system, it generates 36,000 micro-vibrations per second to thoroughly solve mesh blocking, material agglomeration and static adhesion problems of ultra-fine powder under 500 mesh. It improves screening accuracy by 30%-70% and boosts processing capacity by 2-10 times. The whole machine adopts food & pharmaceutical grade 304/316L stainless steel with fully sealed structure to avoid dust leakage, ideal for lithium battery powder, pharmaceutical raw materials, metal powder, chemical pigment and other hard-to-screen materials. Conventional vibrating screens have no ultrasonic self-cleaning function, resulting in high fine powder loss and frequent manual mesh cleaning.
Q2: What mesh sizes can the ultrasonic screen handle? How long is the warranty for spare parts?
A: Standard models support 100-500 mesh ultra-fine powder separation, and special ultrasonic transducers for 800 mesh can be customized. The complete machine enjoys a 12-month warranty, while core accessories including ultrasonic generator and transducer are covered under 1-year warranty. Sieve mesh and sealing rings are wearing parts not included in the warranty, and discounted spare parts are available for bulk long-term orders. It supports 220V/380V voltage, and variable-frequency generators can be customized according to local voltage of different countries.
Q3: Can I send material samples for sieving test? What is your standard production lead time?
A: We accept customer raw materials for free sieving test, and customers shall bear the round-trip logistics cost. Standard in-stock machines can be delivered within 3-7 days. Non-standard customized equipment (custom size, layers, anti-corrosion material, explosion-proof configuration) takes 7-15 working days. The delivery period may be extended by 3-5 days during peak order seasons. We will provide screening test reports and capacity parameters after testing to help customers select proper models and confirm quotations.
Q4: What export certificates can you provide for customs clearance? What trade terms do you offer?
A: CE certification and ISO9001 documents are supplied as standard. SGS, FDA food-grade material reports and explosion-proof certificates can be provided on request. We normally quote FOB our port, and CFR, CIF, DDP door-to-door terms are acceptable. The HS code is 84749010. Full set of customs documents including packing list, commercial invoice and certificate of origin can be offered. All machines are packed with fumigated solid wooden cases to prevent moisture and collision during sea transportation.
Q5: What payment terms are available for overseas orders? Do you support OEM & ODM customization?
A: Our mainstream payment term is 30% T/T deposit, with full balance paid before shipment. Irrevocable L/C is negotiable for large orders. OEM private labeling and ODM structural modification (custom inlet & outlet, dust removal, heightened frame etc.) are supported, and customer brand LOGO can be printed on machines. The MOQ is 1 unit. Tiered wholesale prices are available for long-term overseas distributors. We also provide English operation manuals and remote technical after-sales guidance for global clients.
