Key feature

• Slurry flows down the angled, curved screen.
• Small particles and water pass through screen holes, while larger particles move along the curve.
• Flowing water clears the screen, preventing clogs.
• Separates particles, drains water, and operates without moving parts.

Description

Sieve bend, or DSM screen, is a curved screening device used in mining and industrial processing to separate fine particles from larger ones within a slurry (a mixture of water and solids). Positioned at an angle, the sieve bend allows materials to flow over its surface, where finer particles pass through the screen openings while larger particles continue along the curve.
This gravity-driven separation is essential in dewatering, particle classification, and reducing the load on downstream equipment like cyclones or vibrating screens.
Constructed from durable, corrosion-resistant materials, sieve bends improve efficiency, reduce maintenance, and enhance water recovery in processing plants, making them a reliable choice in heavy-duty mining operations.

Applications of Sieve Bend

1. Mining and Mineral Processing: Used to classify and dewater ores and slurries in gold, copper, coal, iron, and other mineral processing.
2. Wastewater Treatment: Filters out solid particles from wastewater, making it easier to process or recycle water in treatment plants.
3. Chemical and Pharmaceutical: Filters and separates fine particles in slurry mixtures during chemical production or pharmaceutical processing.

Advantages of Sieve Bend

1. Efficient Particle Separation: The angled, curved design enables quick and effective separation of fine particles from larger ones, improving processing speeds and accuracy.
2. Dewatering Capability: Sieve bends can reduce water content in slurries, which is helpful in mining and other industries where water management is critical.
3. Reduced Equipment Load: By removing fine particles early, sieve bends lessen the load on downstream equipment, leading to longer equipment life and lower maintenance costs.
4. Low Maintenance: With no moving parts, static sieve bends are durable, require minimal upkeep, and have low operational costs.
5. Space-Saving: Sieve bends are compact and can often be easily integrated into existing processing lines without needing significant space.

Function Principle

Eloquent Sieve bend works by letting slurry (a mixture of water and solid particles) flow over a curved, angled screen. Here’s the basic idea:
• Curved Screen Design: The sieve bend has a curved, angled screen that allows slurry (a mixture of solids and water) to flow across it. This curvature and angle help guide materials naturally over the screen surface.
• Gravity and Flow: The slurry is introduced at the top of the sieve bend. As it flows downward, gravity and the screen’s curve cause larger particles to continue along the screen, while smaller particles fall through the screen openings.
• Screen Apertures: The size of the screen’s apertures or slots determines the separation cut-off size. Finer particles and water pass through the small openings, while larger particles move along the screen to the discharge end.
• Self-Cleaning Mechanism: As the material moves along the curve, the constant flow helps prevent blockage by naturally “washing” the screen, keeping it free of excess particles.
