What is the working principle of small machine powder test sieve? 

Small machine powder test sieve uses the exciting force generated by the vibration motor to make the powder material on the sieve jump. Particles smaller than the sieve aperture pass through the sieve, and particles larger than the sieve aperture are retained on the sieve. By screening layer by layer, powders of different particle size ranges can be obtained, so as to analyze the particle size distribution of the powder.

The structure of the small machine powder test sieve

 

The structure of the small machine powder test sieve mainly includes the sieve frame, sieve mesh, vibration motor or rotary motor, base and spring, seal, feed port and discharge port. Its compact, modular and durable design makes it widely used in laboratories and small-scale production. Through reasonable use and maintenance, the performance advantages of the equipment can be fully utilized to meet the screening needs of different powder materials.

What are the advantages of small machine powder test sieves?

1. Accurate screening results: Small machine powder test sieves are equipped with efficient vibration motors or rotary motors to provide strong excitation force or rotation force, so that the powder material can be quickly dispersed and passed through the screen. Small machine powder test sieves usually have precise screens and vibration mechanisms, which can provide accurate screening results and ensure that the powder particles are classified according to the required standards.

2. Effectively solve the problem of machine powder blocking the screen: Small machine powder test sieves use vibration or rotation to quickly disperse the powder material on the screen surface, reduce the residence time of the material on the screen, and reduce the possibility of blockage. They are usually designed to handle a small amount of samples and can complete the screening process quickly and efficiently, saving time and labor costs.

3. Easy to clean and maintain: Small machine powder test sieves are usually simple in design and easy to clean and maintain. Keeping the equipment clean can ensure the accuracy of the screening results and extend the service life of the equipment. The fully enclosed design prevents dust from spilling out and ensures the health of operators and environmental safety.

4. Suitable for a variety of powder samples: Small machine powder test sieves are suitable for processing various types of powder samples and can cope with powder particles of different sizes, shapes and properties. Multiple layers of screens can be installed to achieve multi-level screening to meet the screening needs of materials of different particle sizes. For powder materials with high humidity, the screening efficiency can be improved by adjusting the vibration parameters or adding a drying device.

Application scenarios of small machine powder test sieve

Laboratory research: In the laboratory, researchers use small machine powder test sieves to analyze and grade powder materials to determine their particle size distribution. Through screening, researchers can understand the particle size characteristics of powder materials and provide accurate data support for subsequent experiments.

Small-scale production: Small machine powder test sieves are used to screen raw materials to remove impurities and oversized particles. Ensure the purity and uniformity of raw materials, improve production stability and product quality. Through screening, determine whether the particle size of new raw materials meets production requirements to avoid affecting products due to excessive or too small particles.

Quality control: Small machine powder test sieves are used to detect the particle size distribution of powder materials to ensure that they meet relevant standards. Through screening, determine whether the particle size of powder materials meets the requirements to avoid affecting the quality and effect of products due to uneven particle size.

Selection suggestions for small machine powder test sieve

1. Material characteristics: Select the appropriate screen aperture according to the particle size range of the powder material. For materials with high humidity or high viscosity, it is necessary to select anti-blocking mesh design and easy-to-clean equipment. For materials with high hardness or strong corrosiveness, it is necessary to select screens and screen frames made of wear-resistant and corrosion-resistant materials.

2. Screening accuracy: Select the appropriate screen mesh number (such as 100 mesh, 200 mesh, etc.) according to the screening accuracy required by the small machine powder test sieve. If multi-stage screening is required, select equipment that can install multiple layers of screens.

3. Processing capacity: Select a sieve machine of appropriate size (such as 200mm diameter, 300mm diameter, etc.) according to the sample amount screened by the small machine powder test sieve each time. Select equipment with adjustable vibration frequency and amplitude according to the processing capacity requirements.

4. Equipment material: The stainless steel material of the small machine powder test sieve is suitable for most cases, corrosion-resistant and easy to clean. Stainless steel screens are suitable for general materials, and nylon screens are suitable for sticky materials.
