Test Shaker-DAHAN Vibration Machinery

Introduction of Test Shaker

Test shaker is a device used for screening and classifying granular materials, commonly used in laboratories and research fields. It can conduct particle size analysis, screening efficiency test and particle distribution analysis of materials.The primary function of a test shaker is to apply controlled mechanical vibrations or oscillations to the samples being tested. This agitation helps in mixing substances, dissolving solutes, extracting compounds, or conducting experiments that require controlled shaking or blending.

The common screen frame diameters of Test shaker are 75mm, 100mm, 200mm, 300mm, and 400mm. They are divided into metal wire braided mesh test sieves (screen size is 0.02mm-2.36mm) and metal perforated plate test sieves (screen size is 1mm- 125mm), electroforming test sieve (sieve size is 5μm-500μm). Samples of different sizes are separated through a pile of sieves of different sizes, which can be used individually or stacked in 7 layers.

Types of Test Shaker

Working Principle of Test Shaker

Test shaker uses YZU vertical vibration motor as the vibration source of the whole machine. The vibration motor drives the upper vibrating plate to vibrate, and then transmits it through the vibrating plate to the screen frame on the upper part of the vibrating plate. The material particles with the sieve aperture are sieved to the lower screen frame, so that only materials of the same size are left in each screen frame to achieve the separation of different particle sizes and determine the particle size composition of the material, so that the material in the screen frame It can be very effective for filtering, grading and sieving purposes.

Benefits of Test Shaker

Particle size analysis

Particle size analysis can be performed on granular materials to help determine the particle size distribution range of the materials. This is important for materials research, product development and quality control.

Screening efficiency

The screening efficiency of materials on different screens can be tested. By adjusting vibration parameters and screen size, the screening process can be optimized and screening efficiency improved.

Sieving consistency

A standardized screening process is provided to ensure the consistency and repeatability of screening results. This is important for comparative analysis and quality control.

Flexibility

It has replaceable screens and multi-layer screen settings, which can adapt to the screening needs of different particle size ranges. At the same time, some test screening machines also have adjustable vibration parameters to meet the screening requirements of different materials.

Laboratory scale

Typically smaller in size and lower power requirements, suitable for use in laboratory environments. They enable particle size analysis and screening operations in a relatively small space.

Save time and costs

It can quickly screen and classify granular materials, saving the time and labor costs of manual screening. At the same time, through the automated screening process, the possibility of human error is reduced.
