SFJH Rotary Grading Screen

SFJH flat rotary classification screen is a specialized equipment for the screening and classification of feed and granular materials.
It primarily consists of a machine casing, screen frame, drive device, and feeding device, achieving efficient material separation through the rotary screen frame.
The SFJH classification screen is widely used in feed processing, particle production, and other fields, effectively removing impurities to ensure the quality of granular materials and improve production efficiency.

1.Efficient Classification: Enables efficient and rapid material classification, improving screening efficiency.

2.Wide Applicability: Suitable for multiple industries, including feed and granular material processing, capable of handling different types and sizes of particles, with strong versatility.

3.Precision Screening: The screen frame adopts a rational aperture design, achieving precise screening of granular materials, ensuring the quality and specifications of the finished product.

4.Adjustable Operation: Flexibly adjusts based on material characteristics and production needs, achieving more precise classification control.

5.Sturdy Structure: Adaptable to long-duration, high-frequency industrial operations.

6.Easy Operation: Easy to operate and maintain, reducing the difficulty of use and maintenance, improving work efficiency.

7.High Automation: Achieves automation through an intelligent control system, enhancing the overall intelligence of the production line.

8.Dust-Proof and Leak-Proof Design: Reduces environmental pollution and material waste, ensuring cleanliness and tidiness in the production environment.

1.Feeding: Granular materials to be screened are fed into the screen frame area through the feeding device.

2.Screening Area: The screen frame rotates in a flat manner, equipped with a screen mesh with rational apertures. Materials in the screening area undergo the action of centrifugal force and vibration, resulting in a spiral movement of the materials.

3.Classification: Based on the aperture size of the screen mesh, smaller particles pass through the screen, while larger particles are obstructed, forming layers of materials with different particle sizes. This completes the classification process.

4.Discharge: Screened materials are discharged through different outlets based on their size, achieving the classification of granular materials.

The Feed Milling Process typically involves the stages of raw material reception and storage, cleaning, crushing, dosing & mixing (batching), pelletizing, cooling, pellet refinement, screening & grading, packaging, and storage. In specific cases where clients have unique requirements for feed pellet production equipment, additional features such as liquid infusion, curing, spraying, extrusion, drying, and more may be integrated.

1.Raw material storage ：

Given the diverse array of ingredients in animal feed, various types of silos are essential. The feed pellet production line can employ three types of silos, namely hopper silos, flat-bottom silos, and galvanized silos.

2.Cleaning Equipment:

 Primarily employed for eliminating impurities from feed raw materials, particularly large, medium, and ferrous impurities, aiming to achieve the following objectives:

○ Safeguarding both equipment and workers,○ Enhancing the quality of feed products, and ○ Ensuring secure and efficient equipment operation.

3.Crushing Equipment:

In accordance with the process flow and raw material composition of feed production, it is necessary to crush the raw materials to the required particle size.

4.Dosing equipment:

mainly used for dosing various raw materials, mixing materials evenly, including manual dosing type and automatic dosing type.

5.Mixing Equipment:

mix the feed ingredients thoroughly. This stage demands short blending cycles, high mixing quality, rapid discharge, low residue rates, excellent airtightness, and zero dust spillage.

6.Pellet Mill：

This process is to press out the pellets, the finished pellets are good palatability, storage resistance, there are two kinds of flat model and ring model, feed mills mainly use ring die pelletizing machine.

7.Cooling Equipment:

When pellets are extruded from the pellet machine, their moisture content reaches approximately 16%, and the temperature can reach 80-90 degrees Celsius. To facilitate pellet storage, the cooling process is indispensable.

8.Pellets Crusher / Breaker / Bucker :

Break the pellets into small particles.It is mainly used for chicken feed pellet line.

9.Screening Equipment:

After the pellet feed undergoes the crushing process, certain undesired materials such as powder are generated. This process primarily involves separating the non-conforming pellets and powder, allowing the qualified pellets to proceed to the next stage of production.

10.Packaging/Bagging Machine:

This includes both automatic packaging machines and manual packing machines.

11.Dust Removal Equipment:

Essential for eliminating dust and ensuring environmental protection.

12.Conveyor: for conveying feed ingredients, semi-finished and finished feeds
