RETSCH AS 450 Control Vibratory Shaker

RETSCH AS 450 Control Vibratory Shaker

The RETSCH 300260002 AS 450 Control Vibratory Sieve Shaker is a versatile and powerful analytical instrument for research and development, quality control of raw materials, intermediate and finished products, and production monitoring. This vibratory sieve shaker has a controllable electromagnetic drive that can be adapted to every product, resulting in sharp fractions and fractioning even with very short sieving times. For an alternative high-capacity sieve, consider the RETSCH AS 200 Shaker.

What sets the AS 450 Control apart from other sieve shakers is its three-dimensional sieving motion, which works with dry and wet sieving. This is made possible by the optimized electromagnetic drive with RETSCH’s CET Technology, which generates an amplitude of up to 2.2 mm even with a maximum load of 25 kg. This is better than sieve shakers with conventional electromagnetic or imbalance drives.

At the heart of the AS 450 Control is RETSCH’s patented Continuous Energy Transfer Technology (CET Technology), which provides much more energy input than a conventional vibratory sieve shaker. This results in the highest amplitude even with maximum load, for optimum separation efficiency and high reproducibility.

The electromagnetic drive of the AS 450 Control vibrates the sieve stack continuously and transfers its energy to the sieve plate in a controlled way. This produces a three-dimensional throwing motion that distributes the product to be sieved evenly across the entire sieving surface. The advantages of this motion are high stress capacity, smooth operation and short sieving times with high separation efficiency.

The AS 450 Control has many applications, including cement clinker, chemicals, coal, coke, construction materials, fillers, minerals, ores, plastics, sand and soils.

With its many product advantages such as dry and wet sieving, high separation efficiency even with short sieving times, electromagnetic drive, controlled amplitude, easy operation, mobile operation panel for comfortable handling and optional software for control, evaluation and documentation of results, maintenance-free and fulfills all criteria for measuring equipment according to ISO 9001, the AS 450 Control is the perfect instrument for your laboratory or production environment.The AS 450 control is used in research & development, quality control of raw materials, intermediate and finished products as well as in production monitoring. The controllable electromagnetic drive offers an optimal adaption for every product. Sharp fractions are obtainable even after very short sieving times.

With the vibratory sieve shaker AS 450 control RETSCH have designed their first siever for 400 mm and 450 mm sieves which operates with a three-dimensional sieving motion. It can be used for dry and wet sieving. The optimized electromagnetic with RETSCH’s CET Technology allows for an amplitude up to 2.2 mm even with maximum loads up to 25 kg. This makes the AS 450 superior to all other known vibratory sieve shaker based on conventional electromagnetic or imbalance drives.

Introduction

Vibratory sieve shakers are an essential tool in various industries, including pharmaceuticals, food, for dry and wet sieving applications. These devices are constructed to separate particles of different sizes and are ideally suited for materials that are suspensions or have a fine sample size. The vibratory sieve shaker’s electromagnetic provides a 3D throwing motion, ensuring optimum use of the open sieve area and allowing the sample to move equally over the whole sieving surface.

Product Details

Our Vibratory Sieve Shaker is constructed to provide efficient and accurate particle size distribution analysis for a wide range of materials, both dry and wet. Despite its robust and durable construction, the vibratory sieve shaker is light enough to ensure easy handling and stability during operation. These shakers are built to withstand heavy duty use in industries like chemicals, minerals and construction materials. The sieve stack can be customized to fit different sieve sizes and types, for maximum flexibility in sample preparation. This flexibility allows the shakers to handle a wide range of materials, making them the perfect instrument for your laboratory or production environment.

Technical Specifications

Technical specifications vary depending on the model and application. Most models have an electromagnetic system with 3D throwing motion for short sieving times and high separation efficiency. Sieving surface and open sieve area are constructed for optimum use and accurate results. Dimensions and performance of vibratory sieve shakers differ, some models have max amplitude and accuracy for wide range of applications.

Function Principle of Vibratory Sieve Shakers

RETSCH has patented the Continuous Energy Transfer Technology (CET Technology) on which the drive of the AS 450 control is based. CET Technology provides much more energy input than the technology used in conventional sieve shakers. Using representative samples that accurately reflect the original material is crucial for meaningful results during analysis. The AS 450 control achieves the highest amplitude even with maximum load which ensures optimum separation efficiency and high reproducibility.

The electromagnetic system which lets the sieve stack vibrate continuously transfers its energy in a controlled way to the sieve plate, following the harmonic sinusoidal oscillation of alternating current.  The drive produces a 3D throwing motion that moves the product to be sieved equally over the whole sieving surface. The advantage: high stress capacity, extremely smooth operation and short sieving times with high separation efficiency.

Safety

Vibratory sieve shakers are constructed with safety features to ensure safe operation and minimize the risk of accidents. They are made of steel and have features like overload protection and emergency stop buttons. The noise level of vibratory sieve shakers is also minimal to maintain a safe working environment. Some models have a convenient and reliable construction for easy operation and maintenance.

Maintenance and Repair

Regular maintenance and repair is essential for optimal performance and longevity of vibratory sieve shakers. This includes cleaning and checking the test sieves and surface, lubricating moving parts, checking the electromagnetic and other components.

By following a maintenance schedule, you can confirm your vibratory sieve shaker continues to deliver accurate and reliable results, making it a valuable tool for your application.
