Roller Press Rolls

ROLLER PRESS ROLLS

For Roller press spares, we offer following options:

Forged Roll (Single piece or with sleeves) :

Forged roller press roll is the latest generation of special grinding equipment engineered and developed in the end of 20th century. With minimum energy consumption and low operation cost, it realizes the tremendous boost of production of raw materials or cement.

     Materials of Construction

• 42CrMo4
• 30CrNiMo
• 34CrNiMo etc or combinations

Forged shaft with through hard cast sleeves (With Weld profiling) :

• Bianite : Special wearresistant cast iron with excellent toughness is used. Material is through hard, the profiles welded onto the grinding rolls maximise the feed material pull-in capability and minimise the relative movement between the material being ground and the roll surface.
• Compound cast : Special processes ensures high wearresistant hard surface on the exterior surface and towards inner side is a tough material which can take good compression and impact. 

Forged shaft with compound cast sleeve (With Incast profiling) :

The surface is super wear resistant steel with superlative wear resistant and hardness exceeding 60 Rc. The microstructure is martensite with high carbide concentration. The Inner surface is high strength low alloy steel duly normalized and tempered. The mechanical values reach 700Mpa impact toughness.15 J/Cm2. Due to its support, the outer surface can be use under heavy compression and pressure.

The profile in this case is in cast during the  casting stage itself and is maintained upto more than 20,000 hours and therefore the roller virtually becomes maintenance free.

Forged shaft with forged sleeve (with hard studs on working  surface) :

• Tungsten carbide studs
• Stud of 16.5 X 45 mm and 20 X 40 or as required.
