Powder Sieving Machine

Introduction of powder sieving machine

Powder sieving machine is designed for high volume sieving of powders to remove oversized contaminants and agglomerates, easily integrated into your production line, widely used in food powders, pharmaceutical powders, chemical powders, coating powders and Industries including metal powders, enable high throughput and are available in different sizes from 600mm to 2000mm diameter for batch or continuous processing to suit your production requirements.

Application of powder sieving machine

1.Powder Sieving: A wide range of powders can be screened, dusted and classified, eliminating any unwanted solids and ensuring consistent and reliable handling.

2.Powder Recovery: Recycling any excess powder left after production ensures that contaminants such as large particles and agglomerates are removed from the powder, providing an accurate particle size distribution.

3.Powder Classification: The powder produced by the ball mill needs to be separated by the powder sieving machine to meet the particle size standard and the insufficiently ground powder, and the particle size of the powder for different purposes also has different standards. According to the different requirements of different application industries for powder particle size, it can be divided into coarse powder (150-500μm), medium powder (44-150μm), fine powder (10-44μm), very fine powder (0.5-10μm) and ultrafine powder Powder (<0.5μm) and other 5 grades.

Common types of powder sieving machine

Powder sieving machines are used in many industries to protect the quality of powder products by removing excessive contamination. These machines are designed for high volume sieving to increase productivity and minimize maintenance costs. We offer a range of options to meet your screening requirements.

Vibrating Sieve

A wide range of powders can be sieved, dusted and classified, eliminating any unwanted solids and ensuring consistent and reliable handling. We can offer screening machines in a variety of single- or multi-layer configurations for batch or continuous processing.
