While we were able to glue emery to a copper rod and while lines were produced in granite, it did not advance fast enough in our experiment to produce concentric lines on side walls. There are many reasons for this, such as loss of the cutting edge of the fixed particles, wear of the glue, etc. Our gluing was done using a combination of hide glue and water glass (sodium silicate), both of

Lab Report 1 and 2: PRACTICAL 1 : BALL MILLING

28.12.· Ball Mill is the equipment to be used for size reduction. It is a kind of grinder used for intermediate or fine grinding. Ball mill is a metal cylinder which rotates about its horizontal axis. The coarse sugar charged along with the metal balls breaks to fine powder by impact of metal balls. The size reduction is actually to make the too large to be used solid materials usable. It leads to an

Rod mills, how they function Mine .

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. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of

Milling experiments had been carried out using rod of 9.8, 23.8, and 46.0 cm respectively as well as milling time of 30, 60, 210, 360 and 600 minutes. Grain properties were studied by sieve analysis and binocular microscope. The entire rod sizes and 30minutes milling time yielded grain enlargement as a result of van der Waals forces among colliding particles with the help of dampness as a

24.12.· Mills usually contain balls with many different diameters owing to selfattrition, and this helps to improve the product as the large balls tend to break down the coarse feed materials and the smaller balls help to form the fine product by reducing void spaces between balls. In this experiment, coarse salt will be placed into the ball mill. With the aid of metal balls of different sizes

Hot rolling refers to the process of rolling steel at a temperature typically above 900° C, greater than its recrystallisation temperature. This allows steel sheets to be made in larger, thicker sizes, ideal for the manufacture of railway rails, large beams, or girders. Hot rolling vs cold
