We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency
Fine particles make the crusher less efficient and increase the power draft for crushing such small particles which increases the kWhr per ton crushed. Screening and diverting fine particles significantly increases the performance of the crusher.
This step involves breaking up the iron ore to obtain an F 80 grind size before it can be ground. Once the ore has been crushed, it is diverted to a stockpile. The aim of this step is to ensure a smooth crushing process and minimize downtime in the event of a breakdown or to allow planned maintenance in the crushing system, without stopping the grinding and other further steps. If the crusher breaks down, the performance of the entire factory may be affected.
The primary grinding mill grinds the material before it undergoes spiral gravity separation. Efficient grinding means that there will be minimal recirculation material from a cyclone cluster or screening after milling, which decreases the kWhr per ton ground
This step involves the material being retained inside the mill for a specific time (with or without grinding balls) which is calculated by applying Bond’s work index to the process calculation. This index takes into account the material ore hardness and feed size, mill speed, material recirculation, desired fineness, etc. When the material exits the mill, the iron ore is classified using cyclones or vibrating screens that separate fine and large particles. The large particles are diverted back into the crusher and the fine particles will undergo a spiral gravity separation process.
The gravity separation feed range is approximately 30% solid concentration. Process water is used to assist the separation process. The heaviest particles are separated from finer particles by centrifugal force. A collector at the bottom of each spiral collects the heavy concentrate (so-called hematite concentrate) and eliminates the lighter unwanted particles (middlings and tails). This step is repeated two or three times, depending on the desired liberation and iron concentration.
