Standard test sieve

Standard test sieve is a standard equipment for precision screening in laboratories, specifically designed for scientific research, testing, and quality control in fields such as metallurgy, powder, chemical, pharmaceutical, building materials, geology, and national defense. This device is compact in size and lightweight, making it easy to adapt to various laboratory environments and meet the particle size analysis needs of universities, research institutions, and enterprise quality inspection departments for materials such as particles and powders.

Standard test sieve application materials

Powder particles, chemical powders, pharmaceuticals, sand and gravel, abrasives, metallurgical powders, etc.

Working principle of standard test sieve

The standard test sieve’s basic principle is to convert the rotary motion of the motor into a horizontal, vertical and inclined three-dimensional motion through the eccentric weight mounted on the upper and lower ends of the motor shaft, and then transfer the motion to the screen surface. After the material is forced to produce tumbling, rotating and jumping movements on the screen. With the use of standard sieve frame, it can be used for inspection and measurement of the granular, powder materials’s particle size structure, the amount of liquid solids content and the amount impurity‘s vibration screening, filtration, standard test.

Advantage of standard test sieve

The whole machine has a small volume, light weight, smooth and vibration free operation, no noise, good sealing performance, no dust, and high efficiency.
Combined with ultrasonic screening system, it has the ability to automatically clean the screen mesh, improve screening efficiency and detection accuracy.
High screening accuracy and accurate detection results. Suitable for particle shape, particle size distribution, and various detection methods.
It can be installed and used in multiple layers in a three-dimensional manner, with flexible and convenient movement, and safe and reliable continuous operation.
Adopting the standard inspection tools of state-owned Factory 540, the detection is accurate and the service life is long.
