Standard Sieve Shaker

Laboratory full automatic patting standard sieve shaker

Our standard sieve shaker is a fully automatic laboratory instrument that selects dispersed materials based on sample size. Mainly used for particle size analysis of powders, loose materials, and suspended solids in the laboratory.  It can meet all fine and ultra-fine ranges of fine and granular materials, especially suitable for difficult-to-handle materials. It replaces the manual sieve shaker for sample selection, improves experimental efficiency and is commonly used in soil, pharmacy, metallurgy, food, cosmetics, and grains.

According to the working principle, the laboratory sieve shaker can be divided into a two-dimensional mechanical sieve shaker and a three-dimensional electromagnetic sieve shaker. The two-dimensional mechanical sieve shaker is suitable for screening large samples of particles and the three-dimensional electromagnetic sieve shaker is suitable for screening ultra-fine powder and is now an instrument and equipment widely used in laboratories.

It is designed with panel control of the start switch and timer, which is easy to operate and convenient to use. The standard sieve shaker models have corresponding fixtures. It can be installed with 1 to 8 layers of sieves, and multiple samples can be decomposed for the materials tested. With integrated circuit control, the amplitude, frequency, and vibration mode can be adjusted.

Working Principle

The working principle of the sieve shaker is relatively simple, that is, it simulates the artificial use of vibration to drive the sample, and the sample is sieved on the sieve while in motion. There are two modes of vibration: two-dimensional vibration and three-dimensional vibration. Two-dimensional vibration is usually a mechanical vibration, which relies on a motor and an eccentric to drive the screen. There are various methods, like horizontal straight line, horizontal circular, vertical up and down, etc., and three-dimensional vibration. It’s electromagnetic vibration. The electromagnetic coil at the bottom of the instrument uses the discharge to control the screen surface to vibrate. The specimen makes a three-dimensional throwing motion with a wider range of motion and more efficient screening.

Advantages of Standard Sieve Shaker

Standard sieve shaker has the characteristics of saving time and manual re-sieving, easy handling, high screening capacity, great filtration precision, wide usage, and no mesh plugging. It can adjust the frequency, mode, and amplitude of vibration at any time for different test purposes.

Using a high-efficiency screen cleaning device system, the screen mesh will not be blinded, and the screening efficiency and capacity will be effectively improved. Sealed dust removal for safe operation.
