GYPSUM SAFETY SIEVING AND CLASSIFICATION
Gypsum used in building materials must be free from contaminants and controlled in particle size to ensure consistent product quality and process reliability. The presence of foreign bodies or oversize particles can affect downstream operations and final application performance. Selecting the appropriate vibrating sieve at each installation point is therefore essential for both plant designers and end users.
GYPSUM SAFETY SIEVING AND CLASSIFICATION
Gypsum powders, whether natural or synthetic, are typically processed through crushing, drying, and milling stages before final use. During these phases, contaminants and oversize fractions may be introduced or generated, making safety sieving a necessary step to protect equipment and ensure compliance with product specifications.
Safety sieving focuses on the removal of foreign bodies and coarse particles before the material enters critical process stages such as mixing, calcination, or packaging. This operation is particularly important when fine and consistent particle size distributions are required, as even small contaminants can impact product performance and surface finish.

MLT Cuccolini VP2 vibrating sieves are commonly used for gypsum safety sieving at standard throughput levels. Typically installed under silos, sack tip stations, or feeding systems, the VP2 ensures reliable removal of contaminants and oversize fractions while maintaining continuous and stable operation.
When finer cut points below 0.8 mm are required, combined with higher throughput demands, the MLT Cuccolini VTU nutation sieve provides a highly effective safety sieving solution. Installed after milling or before storage and packaging, the VTU ensures precise separation while maintaining high capacity, making it particularly suitable for large-scale production environments.
The nutation motion of the VTU enhances screening efficiency, allowing accurate classification even with fine mesh sizes, while reducing the risk of clogging. This makes it possible to achieve consistent product quality without compromising throughput, even when processing challenging gypsum powders.
Both VP2 and VTU solutions are designed for robust operation in industrial environments, with features such as stainless-steel execution, ease of cleaning, and reliable performance over time. Their flexibility allows integration into a wide range of plant layouts and process configurations.
Using MLT Cuccolini solutions for gypsum safety sieving and classification ensures effective removal of contaminants and precise control of particle size distribution, improving product quality and protecting downstream equipment.
The availability of both standard and high-capacity solutions allows producers to meet different process requirements, maintaining efficiency and reliability even in demanding production conditions.
