The rotary kiln Support roller is mainly used in rotary kiln / dryer / cooler and rotation device, usually there are two sets or three sets support roller in one rotary kiln, there will be a set support roller with thrust roller when three sets support roller
be used.
The support roller bear all weight of device, so it made by quality cast steel, and rolling through a axis in the center of support roller.
Features :
- High-precision dimensional tolerance; Excellent mechanical properties; Produce different dimension based on customer’s requirements; Advanced manufacture equipments and inspection devices; Excellent technical personality; Control the production procedure strictly; Pay attention on the package protection.
Rotary Kiln supporting roller:Cemen Rotary Kiln supporting roller and Lime Rotary Kiln supporting roller We bring forth to our customers Kiln Support Roller for a Rotary Kiln that are designed by our experienced processionals, who hold vast knowledge in this domain. Our professionals uses refractory material that are lined to protect the steel shell and reduce radiation losses.

Features of our products:
Durable
Excellent tensile strength
Accurate level of tolerance
Good dimensional accuracy
Superb surface finishing
Easy to use and install
Possible defects:
| Defect | Causes |
| Unfilled sections | Insufficient material Low pouring temperature |
| Porosity | Melt temperature is too high Non-uniform cooling rate Sand has low permeability |
| Hot tearing | Non-uniform cooling rate |
| Surface projections | Erosion of sand mold interior A crack in the sand mold Mold halves shift |
There are no these problems for us.
Uniform wall thickness will ensure uniform cooling and reduce defects.
A thick section, often referred to as a hot spot, causes uneven cooling and can result in shrinkage, porosity, or cracking.
Corners
Round corners to reduce stress concentrations and fracture
Inner radius should be at least the thickness of the walls
Machining allowance
Add 0.0625 - 0.25 in. (0.16 - 0.64 mm) to part dimensions to allow for machining to obtain a smooth surface.
Advantages of Heat Treatment for the Trunnion Roller
1. Professional, Specific Electrical Furnace, single-minded
2. Vertical Pit Furnace, keep the temperature uniformity during heating, +/-1℃
3. Small deformation, little oxide layer, reduce the material cost
4. Difference materials can be cold at the best speed.
5. Large capacity, completed variety of quenching medium: oil, water, salt water, water based mixture.
