Rolling mill rolls is a kind of cast iron roll manufactured by using the supercooling of molten iron itself and the quenching of die surface, and adding Ni, Cr, Mo alloy elements at the same time. There is basically no free graphite in the matrix structure of the working layer of the roll body, so it has high hardness and excellent wear resistance. This kind of material can be used to produce large size rolls by static compound casting process, which makes the roll body have high hardness and the roll neck have high strength and toughness, showing good thermal stability and accident resistance.

LMM GROUP is one of the professional roll manufacturing base in China, which supply all kinds of large-size rolls for iron and steel enterprises with production capacity of 100,000 tons of all kinds of hot strip mill rolls, section mill rolls, rod mill rolls, cold rolling mill rolls, casting and forging backup rolls.
Flaker Rolls are manufactured keeping in view the immense pressure under which the rolls go through while making flakes, powder and extraction of oil from seed as Flaker Rolls work up to 15000 LBS in a Flaking mill with fast and slow hydration in the case of guar Gum Plants where the seed is directly grinded into high viscosity powder. Therefore the rolls need to sustain extra high pressure. We keep on doing R&D and constant feedback from our customers for improving roll quality to serve our customers with an improved quality of rolls and help us to produce better quality rolls. Our company manufactures rolls as per customers requirements or specifications therefore we supply Rolls of different Grades, hardness, chill depth & finish of the rolls, besides we also suggest our customers to use specific grades of rolls for longer Roll life which gives benefits to our customers
Chill Rolls are the heart of a Roller Mills the better the heart works the better the body performs similarly better the Roll quality better the quality of Flour and Semolina. To give you best quality rolls our R&D team keeps on working on improvements which make better quality rolls and utmost important is your feedback, based on which we keep improving and developing Roll quality. Immense experience and dedication of our team also ensures that our rolls are of highest quality standards. Various grades are made in Flour Mill Rolls they are made according to the customer's requirements and High Speed Roller Mills operating at approx 700 RPM therefore our rolls are balanced at 800 RPM so that they so that they work vibration free and enhances the Flute life to the rolls so as to minimize roll Re Fluting. Only good quality rolls cannot assure good results grinding and fluting are also very important so to serve you with perfect fluting and Grinding we have CNC Roll Fluting Machines by which we flute the rolls to the max accuracy and no overlapping of flutes happens which is normal on conventional Fluting machines. Shaft sizes are made on CNC Lathes so that there is no error while fitting of bearings or pulleys in the rolls.

Backing bearing mainly used for cold cluster rolling mill's roller. This mill take the bearing's outer ring as working surface, generally there's 3 or 5set bearings mounted on each roller and even more, depending on its matching rule. The bearing has thick outer ring and thin inner ring, high accuracy up to abec-7. Cylindrical roller bearing based on two or three rows of rollers and are available as full complement bearings (without cage) or as caged bearings. The advantage of the bearings without flanges lies in their particularly simple geometrical form and their very high radial load carrying capacity. Cylindrical roller backing bearings without flanges or flange rings cannot accommodate any axial load. So it is necessary to position thrust washers of bronze or plastic between the side faces of the outer ring and the support saddles. Thrust washers are not required with backing bearings with flanges (or flange rings) as the design of these bearings enables them to accommodate simultaneously acting radial and axial forces. For different requirement, zsj's backing bearing could fall in 2 classes by material: vacuum-degassed bearing steel and electroslag cemented bearing steel. Combined with advanced heat-treatment, grinding process, the bearing's quality is highly reliable. Zsj standard packing
Zsj products Sendzimir mill rolling bearing This bearing has been specially developed for cold rolling mills of the cluster type, but can also be used for other applications, e.G. Straightening or bending machines. This bearing is a roller bearing has a particularly thick-walled outer ring and can be mounted on stationary support shafts to form back-up or straightening rolls. The forces from the work rolls are transmitted via the support shaft and a system of support saddles to the roll or machine stands. The bearing for cluster mills is produced in many designs but is generally based on double or three-row cylindrical roller bearings. Single row needle roller bearing and Double row tapered roller bearing designs are also available. The logarithmic contact profile between rollers and raceways produces a vastly improved stress distribution under all load conditions as well as when the bearing is misaligned under load. An optimized finish on all surfaces in contact serves to enhance lubrication conditions. As lubricant is supplied to the bearings via the support shaft, the bearings have lubrication holes and some have one or more annular grooves in the inner ring. --individual wooden box packing --unique pe material inside box protection --epal standard pallet --vacuumize plastic bag packing if customer requires
