Sieve shaker testing equipments

What is sieve shaker testing equipments?

Sieve shaker testing equipments are designed for laboratories and quality control, and can quickly and accurately analyze the particle size of granular materials. The equipment uses an advanced vibration motor as the excitation source to generate stable three-dimensional vibration to ensure that the material is fully dispersed and layered on the surface of the screen. The equipment can be adapted to various specifications of circular standard screen frames, with optional diameters of 200mm or 300mm. The screen mesh range is wide, from 4 to 500 mesh, and can be flexibly configured according to different test requirements.

What is the working principle of sieve shaker testing equipments?

During the test, put the material into the top sieve, start the vibrator, the sieve starts to vibrate, the material keeps moving on the sieve, particles smaller than the sieve hole size pass through the sieve, and particles larger than the sieve hole size remain on the sieve. After a period of vibration, stop the vibration, take out each layer of sieve, weigh the weight of the material left on each layer of sieve, and you can get the particle size distribution of the material.

What is the structure of sieve shaker testing equipments?

Sieve shaker testing equipments usually consists of a vibrator, sieve, clamping device and timer.

Vibrator: generates vibration, which can be an eccentric wheel driven by a motor, an electromagnet, etc.

Sieve: A series of sieves with different sizes of sieve holes, usually made of stainless steel, stacked in order of particle size.

Clamping device: used to fix the sieve to ensure the sealing and stability of the sieve during the screening process.

Timer: controls the screening time to ensure the accuracy and repeatability of the screening results.

Price of sieve shaker testing equipments

The price of sieve shaker testing equipments varies by type, specification, brand and configuration (such as mesh size, material, additional functions).

Factors affecting price:

Equipment type and configuration: Ultrasonic test sieves are more expensive because they are equipped with high-frequency ultrasonic systems (36kHz); laboratory vibrating screens are cheaper because of their simple structure.

Screen material and mesh size: Stainless steel 304/316L screens or high-precision electroformed screens (5-500μm) are more expensive; the finer the mesh size (such as >200 mesh), the higher the price.

Processing capacity: Laboratory equipment with a processing capacity of 10-50kg/h is cheaper, and electric vibrating screens with a processing capacity of 50-150kg/h are more expensive.

Additional functions: Such as digital display screens, time relays, dust covers or customized screen layers (1-5 layers) will increase costs.

Brand and service: Well-known brands such as Dahan Machinery provide ISO9001 certification, free delivery, and 30-day returns, and the price is slightly higher than that of small manufacturers.
