Rotary Sifters
Advanced Particle Size Separations with NL Scientific R otary Lab Sifters
NL Scientific Rotary Lab Sifters stand out for their speed, safety, and efficiency, owing to their innovative design. These sifters utilize a reliable and proven design to achieve precise particle size separations of granular materials on test sieves. The moving components are entirely enclosed within the cabinet, minimizing dust and noise emissions. Notably, many state Department of Transportations (DOTs) prefer these rotary sifters for mineral aggregate gradation tests.

These rotary sifters are incredibly versatile, converting within seconds to accomm odate 8in or 12in (200mm or 300mm) test sieve diameters. For 8in or 200mm diameter sieves, the sieve stack capacity includes 10 full-height or 20 half-height sieves. Meanwhile, for 12in or 300mm sieves, the capacity ranges from 6 full height to 13 half-height sieves.
One of the key advantages is the absence of clamping requirements. Sieve stacks are immediately ready for testing upon placement in the cabinet. Once the test is completed, the stack can be removed, and sieves are prepared for the prompt weighing of sample fractions.
Safety is paramount, and these sifters incorporate built-in safety features to adhere to OSHA standards. A s afety switch halts operation when the door is open, ensuring the utmost protection for personnel. The cabinet enclosure effectively manages airborne dust and reduces noise levels. Silent models, in particular, further diminish noise levels by up to 18dB , safeguarding workers' well-being. Both test sieves and drive mechanisms are securely enclosed within the cabinet.
Equipped with a digital timer boasting a large red LED display, these sifters precisely count down test times, accommodating durations up to 99 minutes. The inclusion of a pause function and one-button operation guarantees repeatability, and selectable timing modes offer unparalleled flexibility.
NL Scientific Rotary Lab Sifters are meticulously crafted, employing high-quality components and materials to deliver superior performance and extended service life, even under heavy use. Enhanced safety features are incorporated to safeguard personnel at all times.
The cabinets, constructed from impact-resistant MDF board, undergo precision machining and tight sealing for optimal control over dust and noise. These sifters feature a continuous-duty motor and premium grade bearings, ensuring trouble-free operation. Wide-opening doors, facilitated by heavy-duty commercial grade cabinet hinges, provide easy access. Additionally, a side-mounted handle simplifies cabinet tilting for testing procedures.
