Laboratory electric vibrating screen machine is a device specially used for screening and particle size analysis of materials in laboratory environment. It generates vibration force through electric vibrator to make the granular materials on the screen vibrate, thereby realizing the screening and grading functions1. There are many types of laboratory electric vibrating screen machines, including ordinary laboratory electric vibrating screen machines, ultrasonic laboratory electric vibrating screen machines, slapping type vibrating screen machines and top-impact type vibrating screen machines, etc.

Types and functions of laboratory electric vibrating screen machines

Ordinary laboratory electric vibrating screen machine: Vibration force is generated by electric vibrator, which is suitable for general particle screening experiments and widely used in particle analysis, experimental research and product development in laboratories

Ultrasonic laboratory electric vibrating screen machine: Ultrasonic vibration is added on the basis of vibration to improve screening efficiency and accuracy, which is suitable for screening and grading of fine particle materials

Slapping type vibrating screen machine: Screening is performed by slapping the screen, which is suitable for granular materials that are easy to aggregate or difficult to screen, such as fibrous particles, etc

Top-impact vibrating screen machine: Screening is performed by top-impacting the screen, which is suitable for particles with strong viscosity or materials that are difficult to screen.

Working principle of laboratory electric vibrating screen machine

The working principle of laboratory electric vibrating screen machine is to convert rotational motion into horizontal, vertical or three-dimensional vibration through a motor. The material is evenly spread on the top screen. Under the action of vibration, particles larger than the screen hole remain on the screen, and particles smaller than the screen hole fall through the screen into the next layer. This is repeated, and finally components of different particle sizes are obtained.

Advantages and applications of laboratory electric vibrating screen machine

Ultrasonic vibration: Effectively prevent screen blockage and improve screening efficiency. It is especially suitable for screening fine-grained and sticky materials

Multi-layer screen design: Improve screening accuracy and reduce cross contamination

Diversified vibration methods: Adapt to the screening needs of different materials

Automation control: Timing and fixed-frequency vibration can be achieved through automation control to improve screening efficiency and repeatability.

Laboratory electric sieve vibrating machines are widely used in many fields such as materials science and engineering, powder metallurgy, geology, metallurgy, chemical industry, construction engineering, etc. For example, in powder metallurgy, it is used to screen metal powders and alloy powders to control the performance of the product.
