In the field of particle detection and material classification, the performance of Test Sieve directly determines the reliability of analysis results, and choosing a professional manufacturer is the prerequisite for obtaining high-quality products. Currently, the qualifications of test sieve manufacturers in the market vary, and some manufacturers have problems such as rough craftsmanship and vague standards, which may lead to detection errors. High-quality manufacturers can not only provide products that meet international standards such as ISO and ASTM but also offer customized solutions according to scenario needs, providing stable support for laboratory research and industrial production. Therefore, mastering the method of selecting manufacturers, understanding the advantages of reliable manufacturers, and product applications are crucial for purchasers.

How to select a test sieve?

The selection of test sieves should be based on material characteristics (particle size, humidity, agglomeration), screening accuracy requirements, and production efficiency needs. The following are the differences and applicable scenarios of three common types:

Ordinary test sieve: It is the most basic type, relying on the material's own gravity or mechanical vibration (such as sieve shakers, tapping sieves) to pass through the sieve mesh. It has a simple structure, is easy to operate, and has low cost. It is suitable for dry materials with good fluidity, low tendency to agglomerate, low water content, and relatively large particle size (usually above 100 mesh/150μm), such as classification of construction sand and gravel aggregates, screening of coarsely ground mineral powder, and particle size testing of ordinary chemical raw materials.

Ultrasonic test sieve: It is equipped with an ultrasonic generator on an ordinary sieve frame. High-frequency, low-amplitude mechanical waves are transmitted to the sieve mesh, effectively solving problems such as electrostatic adsorption, agglomeration, and mesh blockage of fine powders (especially <400 mesh/38μm), and significantly improving screening efficiency and accuracy. It is suitable for materials that are prone to static electricity, agglomeration, high adsorption, ultra-fine powders (such as 300 mesh-1000 mesh or even finer), or slightly damp materials, such as fine ceramic powder, graphene powder, metal powder, pharmaceutical micro-powder, pigments, magnetic materials.

Electromagnetic ultrasonic test sieve: It combines high-frequency vibration driven by electromagnetism and an optional ultrasonic system. The electromagnetic drive provides stronger, controllable three-dimensional high-frequency vibration with adjustable amplitude, strong penetration, and faster screening speed; if ultrasonic waves are superimposed, it also has the ability to solve the agglomeration of ultra-fine powders. It is suitable for handling difficult-to-screen, high-viscosity, high-density materials or those with extremely high screening efficiency requirements, such as kaolin slurry, pre-screening of ore slurry, metal powder, fine chemical catalysts, nanomaterials.

What are the key points to consider when choosing a test sieve manufacturer?

When selecting a test sieve manufacturer, a comprehensive evaluation should be conducted from three aspects: qualification certification, production technology, and service capability. This ensures that the products meet standards, satisfy personalized needs, and avoid affecting detection results.

Priority should be given to examining the manufacturer's qualification certifications: whether they have passed international standard certifications such as ISO 3310-1 and ASTM E11, which are the basic guarantee for product accuracy. Second, pay attention to production processes: details such as sieve mesh welding technology and frame flatness treatment directly affect screening stability. At the same time, confirm whether customized services are provided: whether they can meet the needs of special aperture sizes, materials (such as 316L stainless steel), and whether after-sales services include calibration, maintenance, etc.

What are the main application scenarios of test sieves?

Test sieves are widely used in fields such as industrial production, scientific research and testing, and quality control. They are key tools to ensure that material particle size meets standards and product quality is guaranteed.

Ore processing field: Used for classifying and screening mineral powders of different particle sizes to control ore dressing efficiency.

Scientific research and testing field: In laboratories, it provides particle distribution data for the research and development of new materials (such as battery cathode materials).

Pharmaceutical industry: Controls the particle size of pharmaceutical excipients through pharmacopoeia sieves to ensure uniform drug release.
