Kiln Support Rollers are backed by latest technology and provide desired support to cables and other related products. These support rollers are driven to rotate using friction between roller surface and web. The small friction torque of the roller bearings also allow higher speed operations and helps in avoiding possibilities of slippage due to presence of large air film between roller surface and web.

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.

Application:

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.

We can provide OEM service for cement mill and rotary kiln casting parts,marine steel casting parts,sugar mill machinery parts with carbon steel or low alloy steel.

The casting parts can be supplied as following treatment:

Heat Treatment: Normalized, normalized and tempered,quench and tempered

Machining: Rough machined,semi-finished machined,finished machined

Quality warranty and testing equipment:

Magnetic powder inspection

UT nondestructive test

Dye inspection

Leeb hardness testing equipment

Mechanical property test equipment

Metallographic microscope

Direct-reading spectrometer

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.
