Precision-Engineered Screens for Optimal Crushing Efficiency with Precision Meets Durability.

Shanbao Machinery – Your Trusted Partner Since 1989
 

Established in 1989, Shanbao Machinery stands as a leading professional manufacturer of feed machinery fittings, integrating production, sales, and service. Headquartered in the new zone of Meishan Industrial Park, Sichuan, China, our 40,000 sq.m facility houses 3 specialized plants for forging, casting, drilling, and fine turning. With over 30 years of industry expertise among our skilled workforce and China’s only in-house forging & casting factory for die manufacturing, we ensure uncompromising quality from raw material to final product.

Screens: The Core Component for Particle Perfection

As a critical wearing part of hammer mills, our screen sieves define crushed product fineness through type, shape, hole size, opening ratio, and wrap angle. Widely applied in feeds, biomass pellets, medicine, and more, they balance precision and durability. High opening rate designs are ideal for feed production.

Key Specifications

• Material: Q195 cold rolling steel

• Nitriding Depth: >0.12mm

• Surface Hardness: ≥ HV450

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

• Tolerance: Hole distance & aperture error ≤0.15mm

• Customization: Tailor-made solutions supported

Technical Excellence

• CNC Punch Stamping: Uniform, aesthetic holes with maximized area for efficient material flow.

• Special Heat Treatment: Nitriding/nitrocarburizing enhances surface hardness and wear resistance.

Unmatched Advantages

1. High Cost-Effectiveness: Premium quality at competitive prices.

2. Superior Strength: Engineered for heavy-duty operations.

3. Exceptional Wear Resistance: Prolonged service life in harsh environments.

4. Corrosion Resistance: Reliable performance across diverse applications.

Functionality

Our sieves separate particles by size: smaller particles pass through perforations, while larger ones are retained, ensuring strict compliance with particle size specifications. Easily switch between hole sizes to adjust material fineness – smaller holes for precision, larger holes for coarser outputs.
