Lab Test Sieve Shaker

A Lab Test Sieve Shaker processes solid particles and powders by separating them into defined size fractions for quality evaluation. Built with SS304 or SS316L stainless steel contact frames, this equipment handles screen meshes from 20 mesh down to 635 mesh (孔径 0.85 mm 至 0.02 mm). The frame stack accommodates 1 to 8 test sieve layers plus a bottom receiving pan in a single operation cycle, allowing technicians to isolate multiple particle classes simultaneously without manual sorting.

This unit utilizes a 3D three-dimensional or high-frequency electromagnetic vibration drive to impart continuous vertical and rotational acceleration to the material bed. The rapid vertical throwing motion lifts particles off the mesh, while orbital motion forces them across the surface area until each grain finds an opening corresponding to its size, providing quantitative grain-size distribution data for raw material quality control. Laboratory technicians process materials such as metal powders, ceramic granules, cement samples, plastic pellets, soil aggregates, and chemical reagents. Below is the structural layout showing the mechanical component arrangement:

Components and Manufacturing Details

The assembly consists of distinct mechanical parts built to withstand continuous laboratory operation:

• Drive Motor / Electromagnetic Actuator: Mounted inside the weighted cast-iron base to suppress vibration transfer to surrounding workbenches.
• Sieve Frame Clamping Mechanism: Uses twin vertical support rods with a quick-action top clamping knob, allowing operators to lock or release the 1–8 sieve stack within seconds.
• Stainless Steel Sieves (SS304/SS316L): Mesh screens are stretched using tensioning equipment and laser-welded into precision stamped frames, leaving no edge crevices where fine dust can collect.
• Digital Operation Panel: Features an LED timer (0–99 minutes) and adjustable amplitude control switches to regulate vibration intensity.

Lab Test Sieve Shaker Price and Order Information

The unit cost ranges between $350 and $1,200 depending on motor configuration, voltage specifications, and the number of certified stainless steel sieves included in the order. Standalone drive units without extra sieves sit at lower pricing, while complete kits containing 8 mesh screens, a bottom pan, a top cover, and custom voltage motors fall in the upper range. Buyers requesting unit configurations for sale receive a detailed price breakdown based on selected mesh counts and transport options.

Frequently Asked Questions

Q: How to calibrate the lab test sieve shaker?
A: Calibration involves checking amplitude displacement using a calibrated measuring gauge and verifying timer precision with a digital stopwatch. Mesh accuracy is certified using standard reference microspheres passed through each sieve layer, comparing trapped mass fractions against factory calibration charts.

Q: How to clean and maintain the fine mesh test sieves?
A: Ultrasonic baths filled with water or mild detergent solutions clean sub-100 mesh screens without damaging delicate wires. Avoid stiff wire brushes or metal picks. Store dry sieves vertically in designated racks to prevent frame bending and mesh sagging.

Q: What is the delivery time for custom mesh sizes?
A: Standard ISO/ASTM mesh sizes (20-500 mesh) ship within 3 to 5 working days from stock. Custom aperture sizes, non-standard frame diameters (100 mm or 400 mm), or specific 316L wire weaves ship within 10 to 15 business days following order confirmation.
