FDSP can manufacture the ring dies of different materials, types and hole diameters which are suitable for all top brand pelletizers, such as ANDRITZ, CPM, BUHLER, ZHENGCHANG, MUYANG, SHENDE etc Please offer the drawing and specifications of ring dies if you need.Dies-steel mouldFDSP dies are manufactured in the following steels:· X46Cr13 (i.e."stainless" steel or "chrome-steel") · 20MnCr5 (i.e."alloy" steel)· 18NiCrMo5 (i.e. similar to 20MnCr·5 but with a higher alloy content).The X46Cr13 steel dies are vacuum / through hardened. The heat treatment achieves 53-55HRc hardness on the surface and in the core. The high chrome content makes it corrosion resistant. Although it costs more than a normal alloy, X46Cr13 is by far the most common mat...

Ring die is the key component of a pellet mill, but it is also the quick wear part. So proper installation, usage and maintain of ring dies play an important role to pellet mill efficiency and ring die working life. Following are some requirements for proper installation of ring dies (see Figure 1):For normal operation, ring die (3), hoop (4), and driving wheel (7) are connected and fastened by hoop bolt without any relative movement. However, in practical use, some causes will result to relative move, like the bevel of hoop and driving wheel wears or hoop bolt loosens. Especially when roller ...

1.Classifications of pellet appearance:Geometry appearance: length, pellet diameter, cutPhysical appearance: water resistance, powder content, smooth, color and hardness2.The pellet appearance standard is “industry requirements” instead of “industry standard”.Greatly affected by subjective factors, appearance analysis must be made separately.And that is the differences between “industry requirements” and “industry standards” Typical differences of industry requirements粗For middle and low level fish feedDomesticated fish: 3-5 minutes; Free ranged fish: 15-35 minutes.Pig feed In the souther...

Today, ring dies are mainly made of two materials: stainless steel of high quality and alloy steelReasons why stainless steel ring die is suitable for fish feed processing:1. The biggest feature of fish feed is high proportion of crude fibrous raw material. Crude fiber is a kind of plant fiber, whichcan be “soften” or “gelatinized”. Low quenching hardness stainless steel has better cost performance.2. Stainless steel ring die can improve “hourly output” properly.3. Stainless steel ring die makes pellet surface smoother.4. During the whole service period, there is smaller change on pellet ...

1.Inner diameter D and press belt width b According to area theoretical derivation of unit power, inner diameter of ring die shall be within optimal range: A=πDb/P. For ring dies of same area, undersized width makes larger ring die diameter, and then the whole volume increases, which results to unnecessary waste. Oversized width cannot ensure uniform placement of materials so that ring die and roller shell suffers non-uniform wearing, and then working life reduces. In conclusion, suitable width and diameter of ring dies can not only ensure high output, but also improves working life of compone...

Conditioning means any change or adding of powder material during leaving (or entering) mixer until arrives in pellet mill. Conditioning determines pellet quality. Conditioner makes the original pellet rather than ring die.Conditioner determines pelletizing efficiency. Steam conditioning is the main factor of production efficiency. Normally, more sufficient conditioning makes higher output and quality.Condensed steam plays the role as lubricant. Three elements of conditioning1.Temperature (Thermal energy) Steam temperature, surface temperature of conditioner, material temperature2.While e...
