It is widely used in the production of cement, silicate products, new building materials 52555, refractory materials, fertilizers, black and non-ferrous metal dressings and glass ceramics. Dry or wet grinding of various ores and other grindable materials. .
SAG Mill vs Ball Mill. Ball Motion inside a SAG Mill. ... MILL RING GEAR. Ring gears are often supplied with spur gears. They are always split in 2 or 4 pieces in order to facilitate the assembly. Furthermore, they are symmetrical and can be turned round in order to make use of both tooth flanks. The material is cast steel or nodular iron.
Ball mill and rod mill are suitable for different materials. 1. Selection by material's hardness. Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals. 2.
Vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production when they want to design new grinding plants or a new …

the mill feed by abrasion and impact as the rods cascade within the shell. A rod mill differs from a ball mill in that the comparatively rigid grinding media operate in a relatively fixed path and reduction results fram line rather than point contact between grinding surfaces. Conventional rod mills are either high or law discharge. In the high
Ball Mills vs Rod Mills. Post navigation. Previous. Next. When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots ...
Air Swept Pulverizer. The particle feed is mixed with air as it is fed into the mill inlet (1). The beater plates (2) support the hammers (3), and distribute the particles around the periphery of the grinding chamber. The hammers grind the solid against the liner (4) of the grinding chamber. The beater plates rotate between 1600 and 7000 rpm ...
