This work identified the root cause of an early failure occurring near welded joints that connect the slide ring with the head of a ball mill used in an iron mining plant. The ASTM-A516-G60 steel specified for use at this location had a lower carbon content than required. The microstructure presented by this steel consisted of a totally heterogeneous distribution of ferrite grains and pearlite

The Taig milling attachment makes a good small milling attachment for the mini lathe. You must make a mounting block that is about 1" tall to mount this mini lathe milling attachment on the cross slide. The total vertical travel is 1.5" and the dial provides 0.001" increments. The vise width is 2". The table is 2" x 3-3/4". Overall the milling attachment is 2.25" wide, 3.38" deep, and 5.75" tall.

The quality of every product or material analysis depends on the quality of the sample preparation. It is therefore extremely important to consider all the individual milling parameters in order to make an informed choice: material properties, feed size and volume of the sample, grinding time and desired final particle size, any abrasion of the grinding parts – all these factors are significant.

The ring die and rolls of a pellet mill exposed to high temperatures show metal fatigue and must be replaced often. The proper conditioning of dehydrated alfalfa meal will permit the manufacture of over 2 000 tons of pellets during the life of a standard die of 40 mm thickness. Overall, the texture of a soft feed mixture is changed from a meal-like material with bulk density approximately 0.4

As the friction occurring between the ball socket and the spherical segment during relative movements is very small, the bearing shoe easily follows the movements of the sliding ring. There are 4 U--shape grooves in the upper side of the bearing shoe for the high pressure oil supply. Each groove is supplied with a constant oil volume.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about
