Particle screening is an important link in scientific research, engineering design and quality control. Then you need to use a test sieve shaker.  What is a test sieve shaker? Test sieve shaker is a laboratory equipment used for particle screening and classification, also known as laboratory shaker or laboratory vibrating screen. It uses a vibrating screen to separate and classify granular samples according to different pore sizes. It is widely used in materials science, soil analysis, building materials, mining, chemical industry and other fields.

Composition structure

Test sieve shaker usually consists of screen frame, screen mesh, vibration device and base. The sieve frame is the main part of the test sieve vibrating screen. It is usually made of metal or plastic materials. There is an inlet above it for inputting the samples to be screened. The screen is an important part of the bottom of the screen frame and is made of metal wire or synthetic fiber with different hole sizes. The vibration device provides vibration force through a motor or electromagnetic vibrator to vibrate the screen frame and screen mesh. The base is the structure that supports the test sieve vibrating screen. There are control switches and adjustment devices on it to control the intensity and frequency of vibration.

Working principle

Prepare the sample: Prepare the sample to be screened as required. It usually needs to be crushed or dispersed to ensure that the particles can pass through the screen smoothly.

Load the sample: Open the feed port above the sieve frame, and pour the sample to be screened into the sieve frame evenly. As needed, multiple layers of screens can be placed in the screen frame for multi-stage screening.

Start the vibration device: Connect the test sieve shaker to the power supply and start the vibration device. The vibration device will generate vertical vibration force, causing the screen frame and screen mesh to start to vibrate.

Screening process: Due to the action of vibration force, the particles start to move on the screen. Smaller particles will pass through the apertures of the screen and fall into the container below, while larger particles cannot pass through the screen and remain above the screen frame.

Screening results: After the screening process continues for a period of time, stop the vibration device and take out the screen frame. According to the distribution of particles on different sieves, the particles can be classified and analyzed to obtain the screening results.

Advantage

The advantage of the Test sieve shaker is its easy-to-use, fast and efficient sieving process. It can select screens with different aperture sizes according to actual needs, and is suitable for screening particles in different particle size ranges. At the same time, the test sieve shaker can also perform multi-layer screening to achieve a more detailed grading effect.

Application

Test sieve shaker has a wide range of applications in laboratory research, quality control and particle analysis. Here are some common application scenarios:

Materials Science: In materials research, test sieve shakers can be used to sieve and classify powders, granules and granule combinations. It can evaluate the particle size distribution, particle shape and uniformity of particle composition of the material, providing an important reference for material performance and processing technology.

Soil Analysis: Test sieve shaker can be used for sieving and classifying soil samples to determine the size distribution and particle composition of soil particles. This has important implications for soil quality assessment, soil classification and agricultural research.

Building materials: In the field of building materials, the test sieve shaker can be used to screen and classify materials such as sand, stone, cement and concrete. This helps control the quality of the material, determine its particle size distribution, and evaluate its performance in applications such as concrete and pavements.

Mining and Mineral Processing: In mining and mineral processing processes, the test sieve shaker can be used to screen and classify ores and mineral sands. This helps determine the particle size distribution of the ore, the grade of the ore and the processability of the ore, and provides an important basis for ore beneficiation and ore processing.

Chemical and pharmaceutical industry: In the chemical and pharmaceutical industry, test sieve shaker can be used for screening and classifying granular raw materials, powdered drugs and chemical products. This helps ensure that the particle size of the product meets requirements, ensuring product quality and performance.

Powder Engineering: In powder engineering, the test sieve shaker can be used to sieve, classify and classify powder and granular materials. This is of great significance for powder preparation, powder processing and powder property research.

In short, the test sieve shaker is an important laboratory equipment that achieves particle separation and classification through a vibrating screen. It has broad application prospects in particle screening and classification applications, and plays an important role in materials science, soil analysis, building materials, mining, chemical industry and other fields.
