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.

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.
