Vibro Sifter Machine for Powder & Granule Screening
A vibro sifter machine is designed for efficient powder screening and granule screening in industrial production. Using controlled vibration, the machine separates materials by particle size and helps remove oversized particles, impurities, and agglomerates. As a reliable vibrating sifter machine, it can be used for a wide range of materials in the food, chemical, pharmaceutical, ceramic, and metal powder industries. Different screen diameters, mesh sizes, and configurations are available to meet various capacity and screening requirements.
What Is a Vibro Sifter Machine?
The vibro sifter, also known as a vibrating sieving machine, is one of the mainstream vibratory sifters for powder processing and the most widely used screening device. It operates with a three-dimensional circular motion, delivering outstanding screening precision while effectively preventing screen clogging, perfectly matching the processing demands of fine and ultra-fine powders.
All machine parts that come into direct contact with raw materials are manufactured from Q235 carbon steel, SS316L stainless steel, SS304 stainless steel and other customizable materials. This type of rotary vibrating screen can be equipped with 1 to 5 screen layers, realizing multi-stage particle size classification in one single feeding cycle. One single unit can replace several separate screening machines, bringing higher production efficiency and saving workshop space, which fits diverse industrial production scenarios.
How Does a Vibro Sifter Machine Work?
When loose bulk materials—comprising a mixture of particles of varying sizes and coarseness—enter the screen surface, the vibration of the screen box causes the material layer to disperse.
Smaller particles seize this opportunity to pass through the gaps and migrate to the lower screen deck; conversely, larger particles, unable to pass due to the narrowness of the gaps, remain on the screen surface. Consequently, the originally disordered mass of particles undergoes separation—specifically, a stratification based on particle size—establishing a distinct arrangement pattern in which finer particles settle at the bottom while coarser particles remain at the top.
As the fine particles reach the screen surface, those smaller than the mesh apertures pass through, thereby achieving the final separation of coarse and fine grains and completing the screening process.
Structure of the Vibro Sifter
Vibration Motor
This motor generates multi-plane vibrations in the vibrating screen, a motion that accelerates the passage of material through the various screens.
Vibration Damping Springs
These allow the entire upper section of the machine to vibrate freely, helping to minimize power consumption, prevent vibration transfer to the floor, and reduce noise.
Maille du tamis
Maintains tension to facilitate the movement of material along the direction of vibration. This can be either horizontal or vertical. A single machine can achieve both active and gentle material separation simultaneously.
Inlet/Outlet Ports
The inlet features a baffle design to ensure uniform material feeding, while the outlet is equipped with a valve to regulate the discharge rate.
Features of the Vibro Sifter
Multi-layer sieving:
Available with 1–5 screening layers, depending on the machine model. Multiple layers allow materials to be separated into several particle size fractions in one operation.
Wide mesh range:
Supports screen mesh specifications from 2 to 400 mesh, making the vibro sifter machine suitable for both coarse screening and fine powder separation. When screening fine powders, material properties and mesh selection can affect the risk of blockage. Learn more about why fine powder blinds screen mesh and how to prevent it.
Multiple machine sizes:
Available in models from 400 to 1800, with screen diameters ranging from Φ380 mm to Φ1770 mm to meet different production requirements.
Flexible effective screening area:
The effective screening area ranges from 0.1 m² to 2.32 m², allowing customers to select a suitable model based on material characteristics and required throughput.
Different screening configurations:
Smaller models such as 400 and 600 are available with 1–3 layers, while larger models can be configured with up to 5 layers for multi-grade particle separation.
Adjustable vibration power:
Equipped with vibration motors ranging from 0.25 kW to 3 kW, depending on the machine model and screening area.
High-precision particle separation:
Different mesh specifications and multi-layer configurations help achieve consistent particle size separation based on the material and process requirements.
Suitable for different materials:
The vibro sifter can be configured with different screen meshes and machine sizes for powders, granules and other bulk materials used in industrial processing.

Common Types of powder sifting machines
The term “vibrating sifter” generally refers to all equipment that uses vibration to screen materials, including rotary vibrating screens, inline vibrating screens, ultrasonic vibrating screens, and other types.
Crible vibrant rotatif
The equipment is customized to meet various customer requirements, with screen diameters ranging from 400 to 2000 mm, 1 to 5 layers, and materials including 304 stainless steel and carbon steel, to accommodate the screening needs of various powders and granules as well as liquid filtration requirements.
Tamis vibrant en ligne
The machine’s feed inlet and discharge outlet are vertically aligned, allowing material to pass rapidly through the screen from top to bottom. This design is suitable for continuous impurity removal and filtration of high-volume powders and granules.
Tamis vibrant ultrasonique
By incorporating high-frequency ultrasonic waves into the vibrating screen’s screening principle, ultra-fine powders achieve ultra-high-speed movement, keeping the material on the screen surface in a constant state of suspension. This effectively suppresses factors that cause screen clogging, such as adhesion, friction, settling, and jamming.
