One can easily recognize the difference in finish when comparing a cold finished bar to a hot rolled bar. A hot rolled bar comes out of the mill with a rough, abrasive, discolored, and dirty surface. This is because the steel at the mill is finished at temperatures upwards of 1600° F to 2200° F, and at these high temperatures an iron scale ...
The Difference Between the Ball Mill and Rod Mill. 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 ...

difference between rod mill and ball mill [randpic] What are the differences between ball mill and rod mill The rod of diameter from 50 to 100 mm is often used as the grinding medium, and the filling rate of rod mill is 35% to 45%, while filling rate of ball mill is 40% to 50%. Rod i
The basic difference between drawing of rod and wire drawing is the size of the starting material which is processed. Bar drawing is the term used for drawing of rods from the steel rounds, while wire drawing applies to drawing of wires from steel wire rods. Wire sizes down to 0.03 mm are possible in wire drawing.
Answer (1 of 3): The rod mill and the ball mill belong to the mineral processing equipment. They are similar in appearance and grinding principle, but there are differences in structure, performance and application. This paper summarizes the three aspects of the ball mill and the rod mill, hope t...
What are the differences in the galvanizing process? Whether the steel is hot-dip galvanized or galvanized, it can be prepared by a similar method. Clean the steel in an acid bath to remove all oil, paint, grease, mill scale (small pieces of metal), and rust. After hot-dip galvanizing the steel, immerse it in a molten zinc bath at 450°C.
This difference was higher in the fully dry system. Moreover, HPGR in the dry environment liberated more PGM than the wet processing circuit. Flotation of products from different grinding HPGR-rod mill systems showed that, on average, the flotation efficiency of sphalerite was higher in the dry system than for the wet method .

Customers often ask us about the differences between hot rolled steel and cold rolled steel.There are some fundamental differences between these two types of metal.The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade.
The difference between a rod mill and a ball mill_cement. The difference between ball mill and rod mill . 1. Shape and structure. The ratio of tube length to diameter of the rod mill is generally 1.5-2.0, and the inner surface of the lining plate on the end cover is vertical plane. The ratio of cylinder length to diameter of ball mill is small ...
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 extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers. This results in preferential grinding of ...
Analysis of grinding mediaRod mills commonly use steel rods with a diameter of 50-100mm as the grinding medium, while ball mills use steel balls as the grinding medium. The difference in the grinding body is the main difference between the two.
Difference between rod mill and ball mill essay 376 words 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 millto prevent the conditions leading to rod charge tangling the length to diameter ratio is.
The rod mill (Fig 1) is a tumbling mill which is having a large percentage of its volume (30 % to 40 %) loaded with steel rods. The rods are placed axially in the mill and are loose and free to move within the mill. The internal lining of the drum has a series of lifters which raise the rods and drop them at a predetermined point.
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …
The cylinder length-diameter ratio of rod mill is generally 1.5-2.0, while the cylinder length-diameter ratio of ball mill is smaller, only slightly greater than 1. In addition, the cylinder speed of the rod mill is lower than that of the ball mill, so the grinding medium works in the cascading state. 2. Discharging way of ball mill and rod mill

This commutation is an essential part of many processes. Various kinds of mills are there with which different material processing takes place.
Difference Between Ball Mill and Rod Mill Rod Mills. The principal field of rod mill usage is the preparation of products in the 5 mm—0.4 mm (4 mesh to 35 mesh) range. It may sometimes be recommended also for finer grinding. Within these limits a rod mill is usually superior to and more efficient than a ball mill.
Given the additional elements in it, there is a lot it can do and withstand, which is better compared to steel. For instance, it is non-corrosive. Steel rebar, unlike steel, can last up to a hundred years without losing its molecular integrity. It has the ability to withstand chemical attacks and moisture, which don't have any impact on it.
