Liquid vibratory sifter

What is Liquid vibratory sifter?

Liquid vibratory sifter is a device used to separate solid particles from liquid. It uses mechanical vibration to move the solid particles in the liquid relative to the surface of the screen, thereby achieving solid-liquid separation. Filtration accuracy ranges from 0.025mm to 20mm, and the throughput depends on the material characteristics and machine model, typically ranging from 50 kg to over 5 tons per hour. The machine body is commonly made of 304/316L stainless steel or carbon steel with a corrosion-resistant lining. Corrosion protection options include PTFE lining, spraying, or rubber lining to meet the requirements of strong acid and alkali conditions.

The vibration force is adjusted via an eccentric block or electromagnetic drive, allowing independent setting of frequency and amplitude to match material flowability. It supports 24-hour continuous filtration. The screen structure can be flexibly configured as single-layer or multi-layer (commonly 1-3 layers) according to process requirements, enabling the grading, impurity removal, or solid-liquid separation of materials with multiple particle sizes in a single operation.

How does Liquid vibratory sifter work?

During operation, the vibrator inside the liquid vibratory sifter generates high-frequency, low-amplitude vibrations. The liquid and suspended solids mixture is evenly distributed onto the screen from the inlet. Under continuous vibration, the liquid and fine particles rapidly pass through the screen openings, while larger solid particles are trapped. These trapped particles are propelled forward in a parabolic trajectory along the screen surface by the vibration, while the tilt angle of the screen assists in their transport to the outlet. Throughout the process, vibration not only promotes solid-liquid separation but also prevents screen clogging.

Advantages of Liquid vibratory sifter

Liquid vibratory screens generate low noise during operation, causing no noise pollution to the environment; their small size makes them convenient for screening operations in different locations; the material is fully thrown and spread onto the screen by the excitation of the vibrator; liquid vibratory screens are suitable for processing small quantities or materials with few impurities.

Price of Liquid vibratory sifter

The price of a liquid vibratory sifter typically ranges from $3,000 to $10,000. This price difference stems from the equipment's processing capacity, materials, and configuration. Small laboratory models cost approximately $2,000-$5,000, while large industrial-grade high-capacity models can exceed $9,000. If the material is corrosive or requires higher sieving precision, the use of special stainless steel or polyurethane screens and explosion-proof motors will increase costs, potentially raising the price by 30% to 50%. Furthermore, the level of automation control is also a contributing factor.

Liquid Vibratory Screening Solutions

For common water-soluble liquids, such as coolants and syrups, 304 stainless steel screens can be used, offering good strength and corrosion resistance. A standard single-layer or multi-layer vibrating screen is sufficient to meet production needs. If the liquid contains mild acids or alkalis, 316L stainless steel screens are recommended, as they offer superior corrosion resistance. Pairing them with a fully enclosed vibrating screen with enhanced sealing will prevent liquid evaporation and contamination. For high-viscosity liquids such as inks, wedge-shaped mesh or large-aperture metal mesh should be used to reduce screen clogging. High-frequency vibrating screens or ultrasonic systems can be added to improve screening efficiency.
