Supporting Roller of Rotary Kiln

Supporting Roller of Rotary Kiln

Weight7~42 tons

MaterialASTM: 1055 / DIN: 42CrMo4 / BS: 070M55

Application:Rotary Kiln, Cement Kiln

The supporting roller bears the whole rotary kiln part weight (main part barrel, lining brick, heat exchange device in stove, material, tyre, girth gear ring) The barrel and kiln tyre can smooth rotate on the supporting roller So bearing performance of support roller has become one of the measure standard of the rotary kiln product high quality


1.The support roller can bear bigger load, and with good continuous operation performance.

The support roller used ZG55, ZG42CrMo and so on material, it not only can guarantee quality but also has the advantages such as bigger bearing load and better continuous operation.

2.Simple structure, easy to adjust and repair.

The support roller adopted rolling bearing wheel has the characteristics of simple structure, convenient maintenance.

3.The product has high hardness by normalizing and tempering process.

The surface hardness of the final support roller is more than 200HB by normalizing and tempering process. It can guarantee quality of the support roller device of rotary kiln.

Tyre of Rotary Kiln

Weight5-80 tons

MaterialASTM: 1045 / DIN: CK45 / BS: 080M46

Application:Rotary Kiln, Cement Kiln

Kiln tyre is also called riding ring, is one of the main parts of rotary kiln equipment The kiln tyre can pass the all barrel gravity (include the gravity of refractory brick, internal device and material) to riding wheel, and make the barrel smoothly rotation on the wheel rotation, therefore the kiln tyre should have enough strength and durability At the same time, kiln tyre strengthen barrel radial stiffness so it should has enough rigidity


1.High strength and good durability

The kiln tyre of rotary kiln with ZG45 and ZG42CrMO materials can guarantee the strength and toughness, so as to support the barrel.

2.Used advanced double medium quenching process, has strong adaptability

The kiln tyre has high quenching hardness and toughness and uniformity material by double medium quenching. It can be used to all kinds of bad working environment because of good wear resistance.

3.Simple structure and easy to adjust and repair

Girth Gear of Rotary Kiln

Girth Gear of Rotary Kiln

Weight:10-35 tons

Material:ASTM: 1045 / DIN: CK45 / BS: 080M46

Application:Rotary Kiln, Ball Mill

The girth gear is the major component used in rotary kiln and ball grinding mill which is required to be operated in a long time So, the quality requirements during the actual production for the big gear ring are very high


1.The particular heat treatment technology is used for the big gear ring manufactured by Xinxiang Great Wall Machinery which makes the improvement in the structure optimization and the hardness of the product. The performance of wear-resistant and anti-impacting are also enhanced greatly.

2.The high strength steel was used by us in manufacturing the big gear ring. We also take the optimization for the product against the operation characteristics of the rotary kiln to ensure the stability of the component during the long time operation and extend the service life of the component.

3.Our company has rich production capability in steel castings. For the components such as the girth gear ring, we can provide them in large production quantity with short cast period and large amount.
