Clay has been designated as the Rock of the Year 2025 by the German Geological Society (DGGV), underscoring its indispensable role in various industries, particularly in construction materials.

Understanding Clay and Its Applications

Clay is a fine-grained natural soil material containing clay minerals. Its unique properties, such as plasticity when moist and hardness upon firing, make it a versatile component in the production of building materials. In construction, clay is primarily used in the manufacture of bricks, tiles, and cement, contributing to the durability and thermal efficiency of structures.

The Importance of Screening Technology in Clay Processing

Screening is a critical process in clay refinement, aiming to separate particles based on size to achieve desired specifications. Screening machines are employed at various stages of production to remove impurities and classify materials into specific grain sizes. Typical separations target particle sizes ranging from fine powders of about 0.1 mm (18 Me.) to coarser granules up to 10 mm (0.4 inches).

Challenges in Screening Clay

High moisture content → Leads to clumping and blockages in the screening process
Fine particles → Risk of screen blinding, where material sticks and clogs mesh openings
Abrasive nature → Causes increased wear and tear on machine components
Density variations → Inconsistent material flow and classification difficulties
Dust generation → Requires dust-tight screening solutions for a cleaner and safer work environment
