When testing samples, sample test sieve machine is typically used to sieve them. Sieving determines whether the sample's particle size, appearance, and other characteristics meet requirements. Different types of sieve machines can be selected depending on the material state of the sample, such as vibrating test sieves, impact sieves, and ultrasonic test sieves. All three types can install 1-8 layers of sieves simultaneously, achieving multi-level grading. They can also install 200mm or 300mm sieves and offer sieves made of different materials such as stainless steel and nylon.

Advantages of a Sample Test Sieve Machine

The particle size of the sieves in a sample test sieve machine conforms to national standards, making it suitable for comparative testing or quality determination of samples. Only a small number of samples are needed for testing; if the sample meets requirements, production can proceed; otherwise, losses from mass production can be avoided. The sample test sieve machine offers fast testing speeds, requiring only a few minutes, and can simultaneously install 1-8 sieves with different aperture sizes, resulting in high sieving efficiency. By conducting sample testing with a sieve machine beforehand, it's possible to determine the most suitable sieve type, aperture, vibration mode, and material. This provides data for formal production and reduces trial-and-error costs.

Types of Sample Test Sieve Machines

Sample test sieve machines can be selected from vibrating sieve machines, impact sieve machines, and ultrasonic sieve machines. Each of these three types has its own characteristics. Below is an introduction to the three types of sieve machines, along with a comparison table.

Vibrating sieve machines have a relatively gentle sieving force, allowing the sample to pass through the sieve openings through dispersion and gravity. They are suitable for routine particle size analysis and applications requiring non-destructive sieving. They are suitable for sieving dry, free-flowing particles, but not suitable for sieving samples that easily agglomerate, contain water, oil, have high static electricity, or are fibrous.

Impact sieve machines strike the sample with rotation and vertical force. They have a stronger impact force and are suitable for fine particle samples that easily agglomerate, are sticky, and easily clog the sieve. They are less suitable for brittle, fragile samples or samples requiring preservation of their original crystalline form, as this may cause secondary breakage of the particles.

Ultrasonic test sieve machines, equipped with an ultrasonic system, offer high sieving frequency and relatively low amplitude. This allows them to sieve extremely fine, highly electrostatic, easily agglomerated, sticky, and low-density micro-powder samples. It also reduces sieve clogging during the sieving process.

Sample Test Sieve Machine Prices

The price of a sample test sieve machine depends on factors such as the size and material of the sieve frame, the machine's functions, and the number of sieves. For a vibrating test sieve machine with 5-8 sieve layers and digital timing and speed control, the price is typically between $900 and $1800. For a tapping vibrating sieve machine with basic tapping and rotation functions and mechanical timing or simple digital control, the price is around $800 to $1500. For an ultrasonic test sieve machine with a vibrating sieve main unit, an ultrasonic generator, and 1-2 sieves, the price is typically around $1800 to $3200.

Sample Test Sieve Machine Application Case

A cement plant needed to test mineral powder samples to observe whether the particle size distribution met production standards. A Sample Test Sieve Machine was used, equipped with 200-mesh, 150-mesh, and 100-mesh sieves. First, the sieve machine was placed on a level surface. Then, the sieve layers were assembled from bottom to top according to mesh size. A 50g sample of mineral powder was placed in the top sieve. The vibration frequency was adjusted to 1200 times/minute, and the sieving time to 10 minutes, then the equipment was started. After sieving, the mass of residual mineral powder sample in each layer was weighed. Calculations showed that the proportion of material passing through the 200-mesh sieve was 92%, which meets the industry standard of ≥90%, thus the batch of mineral powder was deemed qualified.

The sample test sieve machine provides a method for determining particle size and quality for different samples, such as powders and granules. This allows companies to avoid the risk of quality defects caused by mass production by testing samples in advance.
