The threeroll mill has proven to be the most successful of the range of roll mills which saw extensive development in the 19th century. These included the singleroll mill and the fiveroll mill. The singleroll mill works by material passing between the roll and a fixed bar pressing against the roll.

The Horomill operates on the principle of a horizontal ringroller mill. It was built and introduced into the cement industry with a cylinder diameter of 2200 mm at the Trino cement plant in Italy that belongs to the present Buzzi Unicem cement group.

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 rollermetal interfaces.

Vertical roller mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, cements and ceramics. It is an energy efficient alternative for a ball mill. Vertical roller mill has many different forms, but it works basically the same.

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.

PRINCIPLE OF OPERATION Table roller mills operate in accordance with the principle of pressure comminution, making them suitable for brittle feed products. The product is subjected to compressive stress between the grinding table and the grinding rollers. The specific grinding force (contact force divided by the crosssectional area of

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

The roller mills had corrugated castiron rollers with better bearings and feed control. The differentials, on each roller pair, control the rotation. The nontouching rollers, each ran at a different speed. If both rollers ran at the same speed the grain would travel though with little or no treatment done to it.

The main principle of the concept is that maximum production is obtained from a ball mill when the mill motor power is at a maximum and consequently the specific energy consumption is at minimum. The maximum power point is dependent upon the feed material characteristics, mill liner conditions, grinding media charge and product size requirements.

The Roller Mill consists of two independent Milling Sections located in a common body made of cast iron which reduces vibration arising from grinding. Each Milling Section consists of: The product is fed through the feed glass via distributor and its distributed over the .
