The grinding action of a rod mill is line contact. As material travels from the feed end to the discharge end it is subjected to crushing forces inflicted by the grinding rods. The rods both tumble in essentially a parallel alignment and also spin, thus simulating the crushing and grinding action obtained from a series of roll crushers.

The Main Rolling Processes of the Wire Rod Mill Production Line are: 1) Billet: The billet used in the wire rod mill production line is mainly continuous cast billet, whose side length is generally 120 ~ 150mm, and the length is generally about 6 ~ 12 meters.

Production Process of Wire Rod. Wire rod refers to hot-rolled round steel with a diameter of 5-22mm or shaped steel corresponding to this section. Because it is delivered in coil form, it is also commonly known as a wire rod. The diameter of common wire products is 5-13mm. According to the different types of rolling mills, it can be divided ...

This mill is designed with twin strand configuration at the intermediate mills. Whereas the fast roughing mill, wire rod mill, coil handling areas are separated for individual lines. There are three billet skids for cold charging and three chain transfers for hot charging located in 0m level, which is transported to furnace at 5m level via billet elevator.

Rod Mills, How Do They Work? Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.

the relevant process variables with special computation models and thus determines the optimum stand size for the particular layout. With HL mill stands, plant owners achieve optimum results in bar steel mills, wire rod mills, light section mills and combination plants.

The rod & bar mill Our rod and bar mill is capable of producing 890,000 tonnes each year for a wide range of reinforcing and wire rod products. In 2006 we invested £10 million in a new four-line spooler mill, making ours the first UK mill to produce hot spooled coil, a process vital for achieving grade 500C properties in coil format.

Batch Mill, Ball Mill or Rod Mill: ... Titan Process Equipment Ltd. was incorporated in 1999 to provide quality equipment to the process industries. Our management team has over 30 years of experience in the refurbishing, manufacturing and designing of process equipment.

processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles. This

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

What's special about our bar and wire rod mills is not only their high flexibility, but also their proven reliability. There is an array of products our state-of-the-art mills can manufacture in one mill: angles, squares, flats, channels, rounds, and wire rod.

In Mineral Processing Design and Operations (Second Edition), 2016. 8.3.1 Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rod mill or ball mill, 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.

Wire Rod Mill Process Control Optimiation Project In. The customer agreed to carry out a Profile Mill Fingerprint service for the laying head of the wire rod mill. The plant runs on GE Rx 7i control system and Nelco Drives with a high speed data logger system IBA installed. Details

The quality of wire rod mill process is guaranteed by ongoing technological innovation and strict controls, not to mention the fact that we belong to the Alfa Acciai Group, enabling us to achieve 90,000 tonnes of production capacity per year, optimise operational parameters, and reduce processing costs

Process improvements on rod mills - DM-engineer Process improvements on rod mills The eddy current tester has proven to be useful in detecting various surface defects on hot-rolled wire rod and bar coils. Chat Online

Bars and wire rods are known for the long subsequent processing they undergo in the secondary and tertiary processors until thefinal end products are produce...

Bar Mill Our two bar mills process billets by passing them through a series of rolling stands that stretch and reshape the steel into bars of different lengths and sizes. Rod Mill At the rod mill, hot drawing, cooling and coiling are the processes that transform billets into wire rod.

Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.
