About Shaking Machine-Sieves (Rotap Type)

For dry sieve tests to carry 7 sieves of 6" or 8" dia. sieves. Driven by 0.25 HP motor through reduction gears. The Gear mechanism runs in a oil-bath. Tapping motion is achieved by hammer from top. To work on 220 V AC 50 Hz single phase. Supplied with adopters for 8" sieves but without sieves with Automatic 0-60 minutes Timer

Versatile Sieve Testing

Equipped to support up to 7-8 sieves with a fitted lid and pan, this Rotap type machine streamlines particle size analysis in laboratories. It employs both horizontal and vertical action, which aids in thorough sample separation. The compatible sieve diameter (up to 200 mm) makes it suitable for standard laboratory testing needs.

Safe and Sturdy Construction

Fabricated from mild steel and finished with a corrosion-resistant powder coat, this shaker ensures long-lasting performance. Slip-resistant feet and a robust clamping mechanism keep the device stable during operation, providing reliability and safety for users. The floor-standing design accommodates heavy-duty laboratory workflows.

User-Friendly Operation

The mechanical timer offers a simple, analog interface for precise control from 0 to 60 minutes. Users can opt for continuous or interval shaking. A noise level below 75 dB ensures minimal disruption, making the device suitable for shared lab environments and regular, prolonged use.

FAQ's of Shaking Machine-Sieves (Rotap Type):

Q: How does the Rotap Type Shaking Machine operate during sieve analysis?

A: The shaking machine utilizes both horizontal circular and vertical tapping motions to efficiently agitate sample materials placed within stacked sieves. This dual-action process helps ensure accurate and reproducible particle size separation according to IS standards.

Q: What is the maximum number and size of sieves that can be used with this shaking machine?

A: The machine can hold between 7 to 8 sieves, with each sieve having a maximum diameter of 200 mm (8 inches). These are securely fastened using a spring-type robust clamping system for consistent results.

Q: When should I use the timer function versus continuous operation?

A: The timer function, adjustable from 0 to 60 minutes via an analog mechanical dial, is ideal when precise agitation duration is required for standard tests. Continuous operation can be used for prolonged mixing or for procedures where manual timing is not critical.

Q: Where can this shaking machine be utilized?

A: Designed primarily for laboratory applications, the shaking machine is suitable for material testing, quality assurance, research labs, and educational institutions where particle size analysis and sieve testing are routinely performed.

Q: What materials and features make the machine durable and reliable?

A: The body is constructed from mild steel with a powder-coated, corrosion-resistant finish, and features slip-resistant feet for stability. The robust clamping mechanism and quality materials ensure long-term durability and consistent laboratory performance.

Q: How does the powder-coated finish benefit laboratory use?

A: The powder-coated finish provides exceptional resistance to corrosion and chemical splashes, safeguarding the equipment in demanding laboratory environments and extending service life.

Q: What accessories are included with the machine, and what needs to be purchased separately?

A: The machine comes with a sieve rack, fitted lid, and pan; however, sieves themselves are not included and must be purchased separately to match testing requirements.
