Introduction:

Shanbao Machinery founded in 1989, is a large-scale professional manufacturer of feed machinery fittings, integrating production, sales, and service. The headquarter is located at the new zone of Meishan Industrial Park, Sichuan, China. We cover an area of 40000 sq.m with 3 plants for forging and casting,drilling, and fine turning. We’re the only dies manufacturer who has its own forging and casting factory in China, it means we can control the quality from the beginning.

We’re a professional feed spare designer and have 15 professional technicians, all of whom have more than 30 years of experience in production.

We have produced different roller shells for many famous machine, like Buhler, CPM, Andritz and some others. The Roller shell is another important accessory of the pellet mill. The roller and Dies work together to extrude the feed.

What are pellet mill rollers made of?

Different supplier have different raw material, and the quality is different. The common materials are: 40Cr, 20CrMn, GCr15

We can easily find our high carbon and high chromium bearing steel has a good hardness, and toughness in the blank. These characteristics will be enhanced after quenching and low-temperature tempering.

The maintenance requirements for pellet mill roller shells

Regular Inspection:

Regularly inspect the roller shells for signs of wear, such as pitting, cracking, or uneven surface wear.

This can be done visually or by measuring the roller shell's diameter and comparing it to the manufacturer's specifications.

Cleaning and Lubrication:

Keep the roller shells clean by wiping away any accumulated dust, feed material, or other debris.

Lubricate the roller bearings and other moving parts according to the manufacturer's recommendations to reduce friction and wear.

Balancing and Alignment:

Ensure that the roller shells are properly balanced and aligned within the pellet mill to minimize vibrations and uneven wear.

Periodically check the roller concentricity, coaxiality, and parallelism, and make adjustments as needed.

Replacement:

Monitor the wear rate of the roller shells and replace them when they reach the end of their service life, as indicated by the manufacturer's guidelines or when the roller diameter falls outside the acceptable range.

Replacing worn roller shells in a timely manner helps to maintain the pellet mill's performance and prevent further damage to other components.

Rotation:

Rotate the roller shells periodically to distribute the wear more evenly across the surface.

This can help to extend the roller shells' service life and maintain consistent product quality.

Storage and Handling:

When not in use, store the roller shells in a clean, dry environment to prevent corrosion and damage.

Handle the roller shells with care to avoid scratches, dents, or other surface imperfections that could accelerate wear during operation.

Preventive Maintenance:

Develop a comprehensive preventive maintenance program that includes regular inspections, cleaning, lubrication, and timely replacement of roller shells.

This proactive approach can help to minimize unplanned downtime and maximize the productivity of the pellet mill.

By following these maintenance best practices, pellet mill operators can ensure the consistent performance and extended service life of their roller shells, contributing to the overall efficiency and reliability of their feed production operations.

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.
