Sieving Machine

Overview

XUANYU Ultrasonic Sieving Machine is a high-precision, anti-clogging screening equipment independently developed by Henan Xuanyu Technology Co., Ltd., integrating ultrasonic technology with traditional vibrating screening technology. It is specially designed to solve the problems of screen clogging, low efficiency and poor precision when screening fine, ultra-fine powder and high-viscosity materials. Widely used in pharmaceutical, chemical, food, metallurgy, new materials, electronic materials and other industries, this machine provides efficient, precise and stable material classification, impurity removal and filtration solutions for high-standard production lines and laboratory research, especially suitable for screening materials with particle size below 200 meshes (0.075mm).

Working Principle

XUANYU Ultrasonic Sieving Machine adopts a dual-drive design combining a vertical vibration motor and an ultrasonic generator. The vertical vibration motor serves as the main excitation source, generating horizontal, vertical and inclined composite vibration through eccentric weights at the upper and lower ends, which drives materials to move in a regular involute trajectory on the screen surface, realizing preliminary screening. At the same time, the ultrasonic generator converts electrical energy into high-frequency ultrasonic vibration (20-40kHz), which is transmitted to the screen mesh through the ultrasonic transducer. This high-frequency micro-vibration makes the screen mesh produce rapid expansion and contraction, effectively preventing fine materials from adhering to the screen aperture and blocking the mesh.

During the operation, materials larger than the screen aperture are discharged from the upper discharge port under the action of composite vibration, while materials smaller than the screen aperture pass through the screen mesh smoothly (without clogging) and fall to the lower layer or are directly discharged, completing the high-precision screening process. The vibration amplitude of the motor and the frequency of ultrasonic waves can be independently adjusted to adapt to different material properties (such as fineness, viscosity, humidity) and screening requirements.

Structural Features & Composition

The machine adopts an integrated structural design, with key components optimized for durability, precision and easy maintenance, ensuring stable operation and long service life while improving screening performance. Its main components and features are as follows:

• Heavy-Duty Base: Made of high-strength steel plate, welded and formed, with strong bearing capacity and stable placement; equipped with shock-absorbing springs at the bottom to reduce the impact of vibration on the foundation and surrounding equipment.
• Vertical Vibration Motor: Core power component for main vibration, stable performance, low noise, low power consumption, and long service life; the phase angle of eccentric weights can be adjusted to change the material movement trajectory.
• Ultrasonic System: Including ultrasonic generator, ultrasonic transducer and ultrasonic screen frame, the core component to prevent screen clogging; high-frequency vibration is stable, energy-saving and efficient, and the frequency can be steplessly adjusted.
• High-Precision Screen Mesh: Commonly used 304/316L stainless steel woven mesh, nickel mesh or polyester mesh, optional aperture from 0.02mm (635 meshes) to 5mm, high screening precision, wear-resistant and corrosion-resistant; matched with ultrasonic system to extend service life by 3-5 times.
• Sealed Screen Frame: Detachable design, single-layer, double-layer or multi-layer optional, made of stainless steel, good sealing performance; easy to disassemble, clean and replace the screen mesh.
• Sealed Dust Cover: Stainless steel material, full-sealed structure, effectively preventing dust emission and material leakage, meeting environmental protection and hygiene standards (especially suitable for pharmaceutical and food industries).
• Control Panel: Integrated design, easy to operate; equipped with independent switches for vibration motor and ultrasonic system, and knobs for adjusting vibration amplitude and ultrasonic frequency, with clear indicators.

Core Advantages

• Anti-Clogging & High Efficiency: The ultrasonic system generates high-frequency micro-vibration to completely solve the problem of screen clogging caused by fine powder adhesion, agglomeration and static electricity, with screening efficiency up to 98% (30%-50% higher than traditional sieving machines).
• Ultra-High Screening Precision: The combination of ultrasonic technology and composite vibration ensures that fine materials pass through the screen mesh smoothly, with screening precision up to 635 meshes (0.02mm), which can meet the high-precision screening requirements of ultra-fine powder materials.
• Wide Adaptability: Suitable for screening fine powder, ultra-fine powder, high-viscosity, high-humidity and electrostatic materials, such as talcum powder, graphite powder, pharmaceutical powder, metal powder, etc., which are difficult to screen by traditional equipment.
• Long Screen Mesh Service Life: High-frequency ultrasonic vibration reduces the friction and adhesion between materials and the screen mesh, avoiding damage to the screen mesh caused by forced screening, and extending the service life of the screen mesh by 3-5 times.
• Easy Operation & Maintenance: Integrated control panel, simple operation; detachable screen frame and screen mesh, screen change can be completed in 3-5 minutes; the ultrasonic system has no易损 parts, and daily maintenance only needs regular cleaning.
• Energy Saving & Low Noise: The ultrasonic system adopts energy-saving design, low power consumption (ultrasonic power 50-300W); the vibration motor operates stably, with low noise (≤70dB), creating a quiet and energy-saving working environment.
• Compliant with Industry Standards: Full-sealed structure, in line with GMP, FDA and other industry standards; parts in contact with materials are made of food-grade or pharmaceutical-grade stainless steel, ensuring product hygiene and safety.
