PTN ring die

We manufacture PTN ring dies of different models. Ring die is one of the key parts of a pellet mill, which is wearing part and expensive. Its quality and durability determine the service life, production capacity and pellet quality, furthermore, directly affecting production costs.

The main failure of the ring die is due to worn-out die holes and inner surfaces (rendering it unusable), though cracking and clogging (preventing pellet extrusion) also occur in some cases.While the die's lifespan is largely determined by its material and manufacturing process. Additionally, for the same material and processing method, its life time is also influenced by factors such as raw material properties, processing parameters, and operational techniques.

Moreover, the smoothness of the die hole surface directly affects whether the ring die can discharge material properly during the initial trial pressing.

Our company supply dies with a ID up to 900mm, OD up to 1,440mm,hole diameters from 1.0mm to 30mm, compression rate is up to 25. We manufacture about 5000pcs dies every yearand customized pellet ring dies for different brands of pellet mill, learn more about our ring dies processing

1.PTN pellet mill die characteristics
1.1 Advanced, automatic ring die processing technology: Full automatic CNC ring die drilling machine and vacuum heat treatment technology ensure the quality and working life of ring dies.
1.2 Rich ring die processing experience ensures the depth and opening ratio of the hole of ring die which can satisfy different requirements of poultry, livestock and aqua feed, thus improves the pelleting efficiency.
1.3 The surface of ring die is of good smoothness, high hardness, and the completed pellets are of good shape and neat appearance.
1.4 Quick discharge, high output and the production efficiency of the same size are much higher than ring dies of other brands.
1.5 Different types and hole diameters can be processed.

2.PTN pellet press ring die's technical parameters
Inspect the dimension of forging stock according to the order contract, measure with vernier caliper, and the deviation shall be less than ±1mm.Based on the inner circle, rotating table and dial indicator shall be applied to inspect outer circle of forging stock and face runout, with deviation less than 1.0mm

We can also customize for you according to your drawing. PTN pellet mill die Customization
We can manufacture the ring dies of different materials, types and hole diameters which are suitable for all top brand pelletizers, such as TRIUMPH, ANDRITZ, CPM, BUHLER, ZHENGCHANG, MUYANG, SHENDE etc.
Please offer the drawing and specifications of ring dies if you need.
