Screen Sieve: Your Key to Particle Size Control

As a critical wear part for hammer mills, our screen sieves regulate crushed product fineness through hole characteristics and design. Used in feeds, biomass, medicine, and more, they optimize performance – especially in high-opening-rate feed applications.

Specifications at a Glance

• Material: Q195 cold-rolled steel

• Nitriding Depth: >0.12mm

• Hardness: ≥ HV450

• Hole Types: Circular (high opening) or square (customizable)

• Precision: Errors ≤0.15mm for hole distance/aperture

• Customization: Tailored solutions supported

Technical Features

• CNC Punching: Uniform, high-efficiency holes for optimal material flow.

• Advanced Heat Treatment: Nitriding/nitrocarburizing enhances surface hardness and wear resistance, ensuring longevity.

Key Advantages

1. Value-Driven: High-quality sieves at competitive costs.

2. Robust Construction: Engineered for high-intensity operations.

3. Wear-Resistant: Reduces replacement frequency in demanding environments.

4. Corrosion-Resistant: Reliable performance in diverse industries.

How It Works

Our sieves filter particles by size: smaller particles pass through, while larger ones are retained, ensuring compliance with target specifications. Easily switch between hole sizes to adjust fineness – from fine to coarse – for versatile crushing needs.
