ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.

Strainer uses a perforated plate or screen mesh to remove larger particles from a process stream. The major advantage of a Strainer is that it is reusable. The filter screen is only used once and must be changed when it clogs. The main difference seems to be in diameter of the holes in the media screen also termed as mesh size in case of strainer.

There are many types of mills and bowl mill is one of them, all these mills can face coal hang-up. For taking corrective action during a coal hang-up in bowl mills the operator will have to know the reason for such a hang-up, how the plant will respond, what he has to respond to and what the local operator will have to do. This will reduce the chance of mill trip …

Working principle of ejector :- When a high pressure motive fluid( steam/liquid) enters the steam nozzle, this result in a decreasing pressure and increasing velocity of the fluid again the fluid enters in the diffuser which result in a increasing pressure and decreasing velocity of the fluid so due to pressure difference vacuum is created in between the nozzle and diffuser …
Bowl mill. Similar to the vertical roller mill, it also uses tires to crush coal. There are two types, a deep bowl mill, and a shallow bowl mill. High speed Attrition mill. The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of material being milled and coarse milling media.
Their Parma mixer range, which is manufactured by FPS (Food Processing Systems) of Italy, offers variable speed ratios between the mixing tools and the bowl scraper as an option. Using a bowl scraper to free dough from sides of bowl (step 3), gently ease dough out onto pan. Italian farm women draw it out of stone ovens; "mother loaf."
