Lab Scale Vibro Sifter

Description

Lab Scale Vibro Sifter (also known as a laboratory vibro sifter, R&D vibro sifter, mini vibro sifter, or small vibrating sieve machine) is a compact vibratory screening device designed for small-batch processing in research and development laboratories. It is primarily used in pharmaceutical, chemical, food, and cosmetic industries for:

Sieving and grading powders or granules based on particle size.
Separating solids from solids or solids from liquids.
Removing oversize particles, lumps, or contaminants (de-lumping and de-dusting).

Unlike larger industrial vibro sifters, lab models are portable, low-noise, and suitable for handling small quantities (typically 10–150 kg/hour, depending on the model).

Working Principle of Lab Scale Vibro Sifter

This vibrating energy screen is unit consisting of circular pre-tensioned screen mounted on the frame along with vibrating motor. The vibrating motor imparts three plane vibrations to the screen due to revolving eccentric weights. Total assembly is mounted on suitable springs so that it becomes a independent body which vibrates without parting any vibrations to the foundations.

The machine operates on the principle of gyratory vibration:

A specially designed vibratory motor with adjustable eccentric weights generates three-dimensional vibrations (horizontal, vertical, and tangential).
Material is fed through a top inlet onto a circular screen (mesh).
Smaller particles pass through the mesh and exit via a bottom outlet.
Larger particles move to a side outlet.
Springs isolate vibrations, reducing noise and floor transmission.

Many models are cGMP-compliant (current Good Manufacturing Practice), made from stainless steel (SS 304 or 316), and feature easy screen changes with clamps and gaskets for dust-free operation.

Documentation & Automation Ready — IQ/OQ documentation available; optional PLC system with Graphical User Interface (HMI).

FAQ for Lab Scale Vibro Sifter

What is a Lab Scale Vibro Sifter?

A Lab Scale Vibro Sifter (also known as Laboratory Vibro Sifter, R&D Vibro Sifter, or Mini Vibro Sifter) is a compact, portable vibratory screening machine designed for small-batch processing in research and development laboratories. It is used for sieving, grading, and separating powders, granules, and liquids based on particle size while removing contaminants, lumps, and oversize particles. It is ideal for pharmaceutical, biotech, nutraceutical, and cosmetic R&D applications.

How does the Lab Scale Vibro Sifter work?

The machine uses a circular pre-tensioned screen mounted on a frame with a vibratory motor. The motor generates three-plane (gyratory) vibrations through revolving eccentric weights. Material is fed onto the screen; smaller particles pass through to the bottom outlet, while larger particles are discharged from the side. The entire assembly is spring-mounted, allowing independent vibration without transmitting movement to the floor.

What are the key features of the Lab Scale Vibro Sifter?

Compact GMP model with SS 304/SS 316 contact parts.
Dust-free operation with lid and silicon sealing.
Easy assembly/disassembly for quick cleaning and screen changeover.
Movable & portable design with low operating and maintenance cost.
Spring-mounted system for reduced motor HP and vibration isolation.
Long screen life, low noise, IQ/OQ documentation, and optional PLC with HMI.

What are the available models and capacities?

The Lab Scale Vibro Sifter is available in the following models:

AVS-20: 20–70 kg/hr output, 20″ (335 mm) diameter, 0.25 HP motor
AVS-24: 20–140 kg/hr output, 24″ (520 mm) diameter, 0.25 HP motor

It is also available in larger diameters such as 30″, 36″, 48″, and 60″ depending on requirements.

Which industries use the Lab Scale Vibro Sifter?

It is primarily used in the Pharmaceutical, Biotech, Ayurvedic, Herbal, Nutraceutical, and Cosmetic industries for R&D, pilot batch, and quality control applications. It is also suitable for small-scale operations in Food, Chemical, and other sectors requiring precise particle size separation and contamination-free screening.
