Product Features and Applications
Increased friction coefficient ensures firm grip on fiber raw materials, preventing slippage and output drop
Uniform particle density, less prone to breakage, and smooth surface, reducing dust and waste
Suitable for various raw material conditions such as feed, biomass sawdust, straw, and organic fertilizer
Product Details
01.
No need to replace the entire pressure roller shaft and bearings; only the worn outer shell needs replacement, reducing downtime and improving efficiency
02.
The end caps at both ends are evenly tightened to prevent axial movement of the outer shell during operation and scraping the ring die end face
03.
Both pressure roller shells on the same machine must be of the same material, tooth type, and outer diameter to avoid unilateral stress

FAQ
1)Why does the pressure roller housing slip immediately after replacement, resulting in low production output?
A: ①The surface of the new pressure roller is too smooth, resulting in insufficient friction for material gripping
②The gap between the pressure roller and the ring die is set too large
③Too much lubricating grease was added
2) What is the normal service life of a standard pressure roller housing?
A: Under dry pure wood chips and proper maintenance conditions: 800–1200 hours
3)What problems might occur if two pressure roller housings are used interchangeably (new and old)?
A: ①Increased local wear on the ring die and uneven wear of the die holes
②Significantly reduced finished particle output and unstable forming rate
③Uneven particle length and thickness, leading to a higher defect rate
4) What are the hazards of an excessively small die clearance?
A: ①The pressure roller directly scrapes against the inner wall of the ring die
②The extrusion resistance increases sharply
③The discharge pressure from the die hole is too high
5)What causes abnormal noises and excessive vibration during pressure roller housing operation?
A: ①Insufficient lubrication in the bearings inside the pressure roller
②Uneven wear on the two pressure rollers and large deviation in outer diameter
③Improper installation of the ring die
6)Does a high moisture content in the raw material make the pressure roller housing more prone to damage?
A: Yes, excessive moisture content will significantly shorten the life of the pressure roller shell
