Each roll shop component is designed and manufactured entirely in-house at Herkules.
Hence it is commonly preferred for grinding operation in new plants of higher capacities. However, many ball mills are still in use. Roll presses are also used in, particularly in upgrading existing ball mill circuits as pre-grinders to increase production or to reduce specific power consumption in grinding operation.
In practice both the roll and the strip surfaces are rough. In many rolling processes, the roll grinding process leads to a roll roughness with a pronounced lay, with asperities running along the rolling direction. This longitudinal roughness is in turn transferred to the strip. Isotropic roughness is also common, for example where the
With a wear performance up to 25% longer than the standard High Carbon Grinding Rod, the HTR50 has outstanding resilience and a hardness profile that has a high surface hardness and lower hardness core, we've developed a series of world-class grinding rods that'll reduce mill consumption significantly.
If the relevant explosion-protection equipment is used, air-swept mills are optimally suited for grinding solid fuels, such as coal or petcoke. Single-compartment mills are of a similar design to air-swept mills, but the material is discharged mechanically by a discharge diaphragm. These mills are well-suited for finer feed materials.

A three-roll mill is used mostly for dispersion, but does some grinding as well. It uses three rollers of different speeds and directions to cause the sheer force between them to disperse and grind particles. The three-roll mill is used to disperse material within a media, which is usually some type of semi-viscous material such as cream.

The more roll pairs the mill has, the greater the size reduc-tion it can achieve. For instance, reducing salt feedstock to coarse road salt requires a roller mill with one roll pair, while reducing the material to table salt requires a mill with two or three roll pairs. More about the feeding device. The feeding device is inte-gral to the ...
ROLL GRINDING OVERVIEW. Grinding of paper mill calender rolls is one of the most difficult grinding operations in industry. They are very long relative to diameter, hard, and have close tolerances. They require a good to excellent surface finish. Grinding of other types such as stainless sucker rolls also is no easy task.
Each mill roll is ordered in without journals so we are able to customize the rolls with specific bearing journal configurations. Chilled iron rolls are commonly found in stationary 1, 2, and 3 pair machines and are solid. "Hardened Steel Mill Rolls": This style of mill roll is commonly used in portable and stationary single pair cracker mills.
