Product Description

Introduction:
Shanbao Machinery founded in 1989, is a large-scale professional manufacturer of feed machinery fittings, integrating production, sales, and service. The headquarter is located at the new zone of Meishan Industrial Park, Sichuan, China. We cover an area of 40000 sq.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 designer and have 15 professional technicians, all of whom have more than 30 years of experience in production.
We have produced different roller shells for many famous machine, like Buhler, CPM, Andritz and some others. The Roller shell is another important accessory of the pellet mill. The roller and Dies work together to extrude the feed.
 

Parameter:

Raw material GCr15(High carbon chromium bearing steel)
Depth of hardening layer > 5mm
Roller hardness 58-61HRC
Surface roughness of bearing bore Ra 0.8-1.6
Coaxiality of inner and outer circles

≤0.05mm

Different suppliers have different raw materials, and the quality is different. The common materials are: 40Cr, 20CrMn, GCr15
 

  C% Cr% Mn% category
40Cr 0.37~0.44 0.8~1.1 0.5~0.8 Medium carbon alloy steel
20CrMn 0.37~0.44 0.8~1.1 0.5~0.8 Low carbon alloy carburizing steel
GCr15 0.95 -1.05 1.4-1.6 0.25-0.45 High carbon and high chromium-bearing steel

 
We can easily find our high carbon and high chromium bearing steel has a good hardness, and toughness in the blank. These characteristics will be enhanced after quenching and low-temperature tempering.
 
Surface Type Of The Roller Shells:
 
We have six surfaces for selection as below.
 
GCr15 High Carbon And Chromium Customize Roller Shells With High Wear Resistance And Long Lifespan 0
 
How to select the roller shells:
 
From the surface consider
Straight teeth: have a strong rolling capacity but the materials will be dropped from the two sides.
Closed-end teeth: have a strong rolling capacity and the materials will not be dropped from the two sides. Because the material is easy to slip lead uneven wear, and is widely used in livestock and poultry feed production
Full Dimples: Poor rolling capacity, but the materials won’t be dropped from the sides with even wear.
Suggest to choose hole+teeth for stronger roller capacity and even wear.
 
 
From the modulus to consider
 
Modulus:1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 4.5, 5
 

Modulus Depth of the teeth Teeth Top width Gap Volume
2 4 100 1.97 4.47 168770
2.5 4 80 3.33 4.72 150815
2.5 5 80 2.58 5.47 201403

 
 
Under the same depth of the teeth, coarse tooth (2.5modulus, depth 4) with lower volume and lower rolling capacity. It’s good to extend the grinding time and enhance the hardness of the pellets.
Smaller teeth ( 2modulus, depth 4) with higher volume and higher rolling capacity than the bigger ones.
The output is higher since the material comes out of the holes quickly, but the wear resistance is lower since the width of the teeth is too narrow.
Medium teeth ( 2.5modulus, depth 5) with the biggest volume, rolling capacity medium wear resistance. The material discharge speed is very fast. However, the high volume performance can not be fully utilized under certain conditions, as: lower opening rate and smaller holes.

  • Focus on the low yield and the hole’s opening rate can not be high for other reasons, you can select the medium teeth.
  • The fine teeth can be selected from the press roller to shorten the grinding time if the pellets are hard.
  • If the particle is too soft and the secondary compression is easy to produce large particles, and the coarse teeth can be selected to extend the grinding time of the material in the dies.
