The production of wire rod is a high-tech process that transforms raw materials into high-quality wire. Learn more about wire production.
A rod mill works by tumbling steel rods against the ore particles. This causes the ore to break down into smaller particles, which are then separated from the larger ones. The rods are placed in a rotating drum and are lifted up and then thrown down by centrifugal force as the drum rotates. The tumbling of the rods causes the ore to be ground ...
Own ferrochrome production is an important strategic asset for us. Positive outlook for 2020 despite low ferrochrome pricing. Deep mine project secures our ore availability for the future. Ferrochrome market expected to be short 2020–2021. Global capacity cuts and shutdowns will change the market.

Introduction. The specification for the apparatus to determining a "Bond" rod mill work index is first described in Bond & Maxton (1943). It states that the apparatus is a tumbling rod mill to be operated in a locked cycle test at a fixed circulating load. The geometry of the grinding chamber is described as:
The first step in producing an aluminum wire rod is melting and casting. This involves heating the metal until it reaches its melting point, then pouring it into molds or moulded ingots. The molten metal is allowed to cool and solidify, forming a cylindrical shape known as an "ingot.". This ingot will be used for further processing later on.
Wire Rod. We are one of the leading wire rod producers in the GCC. Used predominantly in the construction sector for making pins, nails, wire and fencing materials, we are able to produce 550,000 metric tons per year, making 110 metres of carbon steel wire rod per second at our high-speed wire rod mill. Once again, quality iron ore product is ...
The entire weight of the rod or rods will be transferred to that spot. The result may be a broken liner. Of course the condition of the mill liners will be a major factor in its survival. Even if the liner doesn't break, …

The combination of automation, process technology, and mechanical equipment is at the heart of the automation and control of the wire rod rolling mill. The objective of a WRM is to reheat and roll the steel billet (input material) into the product 'wire rod'. Wire rods are normally rolled in a high-speed rolling mill, where steel ...

Capacity & Power requirement in Tumbling mills • Amount of Energy supplied depends upon • Mass of grinding media • speed of rotation • Max. distance of fall • Best predicted by computer simulation based on experimentation • Rod mill – 5 to 200 ton/h of 10-mesh product – 4 kWh/t • Ball mill – 1 to 50 ton/h of 70 to 90% of 200 ...
Rod Mill Design Calculations. EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 – Open Circuit Grinding – when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required ...
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). Grinding action is by line contact between the rods …
As a rule, wire rod mills are designed for an annual output of between 300,000 t and over 800,000 t (two strand mills). The mills are capable of rolling at speeds ranging from 50 meters per second ...
Rods are loaded or charged into a Rod Mill using a mechanised charger. The rod charger with extendable boom moves rods safely inside the trommel/trunnion before charging with a typical 30 seconds or less cycle time per rod. How you charging a rod mill is best explained by the video below. ...
The rod mill motor power is in horsepower at the mill pinion-shaft. For different length rod mills power varies directly as rod length. For difference between new and worn liners increase power draw by 6%, and adjust for bulk density per Table A. Wet grinding rod mills are normally used in minerals processing plants.

The characteristics of the rod mill are that the product is relatively rough. Still, the particle size is uniform, containing less coarse sand and sludge, and the over-grinding is lighter. The discharge particle size is usually between 0.833~0.147mm, and the particle size characteristics of the rod mill product differ from those of the rod mill.
