The housing of a work roll or backup roll bearing is known as roll chock or simply chock. Chock is the basic part of a rolling mill. It is mounted in the window of the roll stand housing between the posts with a small clearness. The roll stand housing encloses and supports the chock assembly.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
How Roller Mills works? The machine is used to grind barite, calcite, potash feldspar, talcum, marble, limestone, cream and slag below scale 7 of Moth's hardness and 280-odd sorts of non-inflammable and non-explosive stuff in the traded of mining, building material, chemical engineering and metallurgy for power generation and processing.

finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".
sensitiveness for mill chatter and for building up a thermal crown. The higher sensitiveness for peeling compared to HighCr rolls can be described as follows. - Peeling takes place when the oxide layers of the work rolls reach a critical thickness. An adequate roll cooling reduce can the growth of oxides by reducing the time of
They have lower specific energy consumption than ball mills and the separator, as in raw mills, is integral with the mill body. In the Loesche mill, Fig. 2.23, 16 two pairs of rollers are used. In each pair the first, smaller diameter, roller stabilises the bed prior to grinding which takes place under the larger roller.
Roller mills use the process of stress (which is applied by the rotating wheels) and attrition in milling of solids in suspensions, pastes or ointments, and some solid materials. The rollers rotate at different speeds and the material is sheared as it passes through the gap. To obtain the desired particles size, the following should be controlled;
Horizontal roller mills use 65-70% of the energy used in ball mills. Roller press (high-pressure grinding rolls): In this technology materials are crushed between two counter-rotating rollers. These rollers are up to 2 m in diameter and 1.4 m long. Roller presses use 50-65% of the energy used in ball mills.
Colloid mill is a machine used in the disintegration of solid particles or droplet size of a liquid present in suspension or emulsion. The machine consists of an inlet (which is subjected to a tremendous shearing action that effects a time dispersion of uniform size) and an outlet. Colloid mill works on the rotor-stator principle.
The plate is worked in a rolling mill. You'll need to harden your metal from time to time, and a rolling mill is excellent for hardening sheets and wire. You already know that the metal must be washed before printing, but each trip …
The roughing mill also contains edger rolls that are used to roll the edge of slab and center it. A rectangular head end is critical to thread the finish mills and down coilers properly. An uneven tail can damage work-roll surfaces or cause threading problems for the next production process.
Figure 1 is the four-roller mill physical map, in which 1 is the hydraulic cylinder, 2 is the frame, 3 is the upper supporting roll, 4 is the upper work roll, 5 is the lower work roll, and 6 is the lower supporting roll. Figure 1 . The four-roller mill physical map.
I originally planned to make a cement roller mill but this investigation is being tackled by others (see box on previous page). Roller dimensions: The question of roller dimension and texturing is very important to the design and success of a mill. We know a 1½-in.-diameter roller with a medium knurl works well on a homebrew mill.
Getting dusty
In this type of mill, the rollers are both adjustable. In these mills, rotation of that two rolls is made in two different directions. In this operation, the metal is passed between two rollers that rotate at the same speed but it is in the opposite direction. It is used in slabbing, plumbing, rail, plate roughing work and many other areas.

Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments. The grinding process of vertical roller mills. · The grinding process by roller mills requires high grinding forces between the grinding elements.
Pin mill work by similar principle as hammer mills (impacts and shearing) but with typically faster tip speed rotor-stator configuration of intermeshing pins which impact the particles as solids are directed through the intermesh pins. The mill product leaves by centrifugal forces to the periphery and is then collected or further processed.
Roller mills are used around the feed mill to perform a variety of tasks. Applications include crumbling pellets, cracking corn, dry rolling and steam flaking grain, and grinding corn, wheat, or milo for mash and pelleted feeds.
