RETSCH AS 200 Vibratory Shaker for Vibratory Sieves

RETSCH AS 200 Vibratory Shaker for Material Sample Preparation

Sieving is a widely used process across industries such as food, pharmaceuticals, construction, and materials testing. It helps separate particles by size to maintain product quality and consistency. Vibratory sieve shakers are suitable for both dry and wet materials, making them ideal for powders, granules, and slurries.

Industrial vibratory sieves remove oversized particles and ensure only the desired particle sizes pass through. This makes them essential in laboratories and production environments where accuracy and repeatability matter.

High-Capacity Vibratory Sieve Shaker: RETSCH AS 200

The RETSCH AS 200 Vibratory Shaker is designed for research and development, quality control, and production monitoring. Its controllable electromagnetic drive adapts easily to different materials and delivers sharp fractions in a short time.

The AS 200 is built for durability and continuous operation, making it suitable for demanding laboratory and industrial environments. For powder mixing and homogenization before sieving, laboratories often pair it with the RETSCH Mortar Grinder RM 200 to achieve uniform sample preparation.

Advanced 3D Sieving Motion

The AS 200 Digit version is recommended for applications that require:

• Digital time display
• Interval operation
• Analog amplitude adjustment
• Optical monitoring of vibration height

Its patented 3D throwing motion ensures the sample moves evenly across the entire sieve surface. This results in high stress capacity, smooth operation, and short sieving times with excellent separation efficiency.

For labs comparing models, the RETSCH AS 200 Basic Sieve Shaker offers a reliable solution for standard sieve analysis applications.

Materials & Applications

The RETSCH AS 200 is suitable for a wide range of materials, including:

• Cement clinker and construction materials
• Chemicals and fertilizers
• Coffee, grains, seeds, and food powders
• Minerals, metal powders, and plastics
• Sand, soils, washing powder, and flours

Because of this flexibility, it is widely used in pharmaceuticals, recycling, food processing, and powder coating industries.

Key Advantages of the AS 200

• Dry and wet sieving in one unit
• High separation efficiency with short sieving times
• Electromagnetic drive with 3D motion
• Maintenance-free operation
• Sieve stack height up to 450 mm
• Adjustable time, amplitude, and interval
• Digital timer and ergonomic design
• Easy operation and repeatable results

For laboratories that also require traditional mechanical shaking methods, RO-TAP sieve shakers are available as complementary solutions for precise material separation.

Function Principle

Each AS 200 vibratory shaker uses a RETSCH-patented electromagnetic drive. This system generates a controlled 3D vibration that distributes material evenly over the sieve surface. The result is fast classification, high reproducibility, and precise particle size separation.

Design, Operation & Methods

The sieve shaker consists of a sieve stack, vibration unit, and control system. Operators can adjust vibration intensity and time to suit the material.

• Dry sieving is ideal for powders and granules
• Wet sieving is used for fine or sticky materials in liquids

This adaptability makes the AS 200 suitable for laboratory testing and production quality control.

Why Choose the RETSCH AS 200

The RETSCH AS 200 Vibratory Shaker combines precision, durability, and ease of use. Its advanced motion, adjustable parameters, and wide material compatibility make it a dependable solution for accurate sieve analysis in laboratories and production facilities.
