ROTAP SIEVE SHAKER (AZA 1302)

Description

Rotap Sieve Shaker is a robust and precise instrument designed to simplify and standardize the particle size analysis process in laboratories and industrial settings. Whether you’re testing soil samples, aggregates, powders, or granules, this machine provides fast, accurate, and reproducible results by combining tapping and vibratory motions, closely mimicking manual sieving.

Manual sieving can be inconsistent, labor-intensive, and time-consuming. In contrast, the Rotap Sieve Shaker automates the sieving process, significantly improving efficiency, repeatability, and data reliability. It is widely used across industries including geotechnical engineering, pharmaceuticals, food processing, mining, construction materials, environmental science, and quality control labs.

At the heart of its performance is a mechanical system that generates both horizontal circular motion and vertical tapping, enabling thorough separation of particles through multiple stacked sieves. This dual action allows finer particles to pass efficiently through each sieve while preventing clogging and particle clustering.

The unit accommodates 8-inch and 12-inch diameter test sieves, with the ability to stack up to 6 full-height or 13 half-height sieves, depending on the model. This versatility allows users to run a full-scale analysis on one sample, achieving clear granularity distribution in a single operation.

One of its core features is the built-in digital timer, which allows for accurate control over the test duration. Simply load your material into the top sieve, secure the stack, set the timer, and press start. The machine handles the rest, delivering consistent results across all test cycles.

Constructed from durable, vibration-resistant materials, the shaker’s sturdy metal frame ensures long-term usage under demanding lab environments. Optional accessories, such as a sound-dampening cabinet, further enhance usability by reducing operational noise.

For fine powders, coarse aggregates, soils, or chemicals, consistent motion and timing are critical. The Rotap Sieve Shaker delivers on both fronts, reducing variability and enabling reliable particle size classification from 4 inches down to 20 microns (with appropriate sieves).

Whether in an academic lab or a production site, it streamlines the process of validating material quality and consistency. It complies with ASTM E11 and ISO 3310 standards for sieving accuracy and testing procedures.

Common applications include:

• Soil mechanics: Classifying sands, silts, and gravels

• Construction materials: Analyzing aggregate gradation in concrete or asphalt

• Pharmaceutical R&D: Verifying powder uniformity and granule sizes

• Mining and metallurgy: Sorting ores and fine particles

• Food and agriculture: Testing grain and powder consistency

By automating sieve analysis, you reduce user fatigue and improve productivity — a crucial benefit in high-throughput or high-stakes testing environments.

FREQUENTLY ASKED QUESTIONS (FAQ):

Q1: What is the primary use of the Rotap Sieve Shaker?
It is used for precise particle size analysis by separating granular materials into size-specific fractions.

Q2: Can it handle wet sieving?
No, this model is designed for dry sieving only. Wet sieving requires special equipment.

Q3: How many sieves can I use in one stack?
Typically, you can use up to 6–8 sieves in a stack, depending on sample volume and sieve depth.

Q4: Is it noisy during operation?
It has mechanical tapping, so some noise is expected. However, sound enclosures are available.

Q5: Does it comply with standard testing protocols?
Yes, it complies with ASTM and ISO standards for sieve analysis.
