Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the roller-metal interfaces.
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.
Raymond Roller Mills: More than 2,000 roller mills have been supplied since the first mills were designed in the late 1800's. These early machines were the forerunner of the heavy-duty, rugged ring-roll mill manufactured today. The roller mill provides the needed flexibility to economically and efficiently process a wide variety of materials.
Raymond mill is mainly composed of main unit, analyzer, fan, dischargeing cyclone separator, powder cyclone separator and air duct. Among them, the main unit consists of frame, blow shell, shovel, grinding roller and grinding ring. Working principle of Raymond mill The rollers tightly rolled on the ring under the effect of centrifugal force.

1. Rolling - Introductory concepts: 1.1 Introduction Rolling is one of the most important industrial metal forming operations. Hot Rolling is employed for breaking the ingots down into wrought products such as into blooms and billets, which are subsequently rolled to other products like plates, sheets etc.
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill - built to last, reliable and energy-efficient - is the optimum solution when it comes to performing several process steps in one unit.

Operation of the Williams Roller Mill System is completely automatic. The feeder (A) introduces raw material into the grinding chamber in the base of the Roller Mill (B) at a rate determined by pressure variations with the grinding mill. Plows located ahead of each roller direct the material upward and between the grinding rolls and the heavy alloy steel bull ring where it is ground to size.

Vertical roller mill is a kind of grinding machine for cement raw material, cement clinker, slag and coal slag. It has the features of simple structure, low cost of manufacture and use.Vertical roller mill has many different forms, but it works basically the same.
Working Principle & Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the ...

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. While each application has some unique aspects, maintenance and operation of the equipment is remarkably similar.

At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing operations such as forging, sheet metal working, wire drawing, extrusion, and machining.
