Precision and Durability Engineered Nitriding Screens for Pulverizers

Reliable Screens – Engineered for Pulverizer with High Precision and Durability

Shanbao Machinery – A Legacy of Quality Since 1989

For over 35 years, Shanbao Machinery has been a trusted name in feed machinery fittings, offering integrated production, sales, and service. Based in Meishan Industrial Park, Sichuan, our 40,000 sq.m facility includes dedicated plants for forging, casting, and precision machining. With a skilled workforce (30+ years of experience) and China’s only in-house forging/casting factory for dies, we guarantee quality at every stage.

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.

Founded in 1989 and with two subsidiaries, Sichuan Meishan Shanbao machine mould co., ltd is one large and professional feed machinery spare parts manufacturer with integration of production, sales and service.The headquarter is located at the new zone of Meishan industrial park Sichuan province ,China.

With the support of strong technical force, excellent equipment, complete testing instruments, and many years of practical experience and scientific research, so we can manufacture a series of parts and accessories for feed machinery use, including ring dies, flat dies,roller assembly, screw-head, screen-mesh,hammer, striking hammer-head, gear ring and so on, which are of application in feed industry, etc.

The key process of production is automated by using international advanced multi-station CNC gun drilling technology and vacuum heat treatment technology in 2001 and the company also expanded another new production line in 2012, which makes all process of production automated from drilling, pressure-reducing, chamfering. The company has 21 sets of four-axis CNC gun-drilling machine tools that equipped with large vertical vacuum furnace for quenching. Our fine products with good features, like good wearing resistance,highdegree of finishing,high cost performance.

The productivity of pellet feed by our ring die is up to 40 million tons per year.

In Dec. 2002, the company was awarded the certificate of ISO 9001:2008 that issued by China quality certification center. In Apr. 2003, the company acquired the licence of import and export qualification .

Our customer contains: Charoen Pokphand Group(CP), CJ Group(Korea), Purina Feed(USA),Tongwei Group,DaChan Food, Uni-President China, New-hope Liuhe Group and Sichuan Tequ Group, Te Qi Li Shi Group, Hunan TRS Group,Hunan Jiuding Group, Da Bei Nong Group, Huan Shan Group,Guangdong evergreen Group, CHIA TAI CONTI GROUP,, Guangdong Chia Tai Conti Group,Guangxi Rui Kang Group , Guangxi Liyuan Group, Fujian Huagang group and etc.

The company established the quality policies of customer satisfaction, integrity operation, first-class quality, technological innovation. and the essence of enterprise culture of "being realistic and dedicated", the concept "working with customers to make granules" was integrated into the production and service.

We also established service network covering the whole country, aim to provide better products and services for the majority of users.
