Expert-Designed Pellet Mill Dies For Screw Type Die With High Wear-Resistance

Product Specification

Introduction:

Shanbao Machinery, founded in 1989, is a large-scale professional feed machinery fittings manufacturer, that integrates production, sales, and service. The headquarter is located at the new zone of Meishan Industrial Park, Sichuan, China. Covering an area of 40000sq.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 manufacturer and have 15 professional technicians, all of whom have more than 30 years of experience in machinery production.

The die is the most crucial part of the pellet mill since it directly affect the feed’s PDI, size, durability, hardness, colors and some others. The die’s price should be the most expensive of the consumable parts of the pellet mill. So using the right and best die is the most important thing during feed production.

Parameter:

Material Composition: The raw material used for this parameter is X46Cr13, a type of stainless steel alloy.

Attachment Method: The type of die is designed for a clamp and screw attachment system.

Surface Finish: The hole finish has a surface roughness (Ra) ranging from 0.4 to 1.2 micrometers, indicating a relatively smooth surface.

Hardness Range: The hardness of the material falls within the 52 to 55 HRC (Rockwell C scale) range, which is a common hardness specification for industrial applications.

Blind Hole Configuration: The parameter specifies that there are no blind holes, meaning all the holes pass completely through the die.

Heat Treatment Process: The die undergoes a vacuum heat treatment process to enhance its mechanical properties and performance.

Hole Diameter Range: The hole specification for this parameter covers a range of 1 to 12 millimeters in diameter, providing flexibility in the size of the pellets produced.

Dimensional Precision: The parameter suggests a level of precision in the hole dimensions, ensuring consistent and reliable pellet production.

Material Strength: The X46Cr13 stainless steel composition provides a balance of strength, wear resistance, and corrosion resistance, making it suitable for demanding pelleting applications.

Manufacturing Technique: The combination of the material, attachment method, and heat treatment process indicates a well-engineered and high-quality manufacturing approach for the die.

How to choose the best raw material for your pellet mills?

The main trade-offs with using carbide are typically higher initial cost and potentially increased brittleness compared to stainless steel. However, the longer service life and reduced maintenance can often offset the higher upfront investment, making carbide a compelling option for many feed production applications.

It's important to carefully evaluate the specific requirements of your feed material, production volumes, and operating conditions to determine the optimal die material. Shanbao Machinery's team can provide guidance and recommendations to help you make the best choice for your pelleting operation.

The pattern of the holes:

The hole's pattern will be designed based on the feed ingredients, particle size, PDI, and particle hardness.There are several types of holes, the most common structures of die holes are straight holes, release stepped holes, external conical holes, internal conical holes, etc. Different die-hole structures are suitable for the different raw materials and feed formulas for pelleting.

Compression ratio:

Generally, the higher the compression ratio the denser the finished pellets, but it does not mean the better pellet. The compression ratio should be calculated based on raw materials for pellets and types of feed, buyers can customize dies with different hole diameters and compression ratios according to the situations and requirements.
