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.
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.
