The Process Flow Diagram is a graphical representation used to demonstrate major components of a process in an Industrial plant or manufacturer, it is widely used in Chemical/petroleum or process engineering.. The Process flow diagrams are used to understand the process and its sequence, model a process, document a process, ensure quality control and standards plus increase efficiency.

particle size. A grinding mill needs a classifier to extract the particles that have been milled sufficiently finely, and to send oversize particles back to the mill for further grinding. A cyclone does this, with the cyclone overflow being the mill final product, and the underflow reporting back to the mill feed. This

Product from the secondary ball mills is classified by cyclones and cyclone underflow is returned to ball mill feed and cyclone overflow reports to final product which has 80% passing 105 microns. After two stage of deslime cyclones, ore is sent for the reverse flotation to produce final product >65% iron for pallet production.

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.

5. Abstract The Ball mill is one of the most important equipment in the world of chemical engineering. It is used in grinding materials like ores, chemicals, etc. The types of ball mills: batch ball mill and continuous ball mill with different grinding media and different design depend on the nature of the input material and the nature of the output which I need.

Hydrocyclone in Operation Cyclone in Operation. The hydrocyclone operation consist of having the ore slurry pumped into its feed inlet, the ore is then separated by size with the fine material coming out of what is referred to as the "OVERFLOW" via a Vortex Finder. The mineral that still requires grinding is named the "UNDERFLOW" via the Apex Finder.
