Factors Influence Ore Grinding Mill Efficiency. Abstract. The grinding efficiency is the most important parameter to evaluate machine performance. This article discussed the factors that influence grinding efficiency including article size to mill machine，milling medium，slurry rheological properties，underflow ratio，liner，grinding aid etc.
Compliance with the ideal grain size and the solids load in the transition from the last grinding stage for the flotation cell requires monitoring of the ore suspension in real time. This measurement task places high demands on the technology used.
1) Crushing and grinding of the ore 2) Concentration or benefaction of the ore 3) Extraction of crude metal from concentrated ore 4) Purification or refining of the metal Crushing and Grinding of the Ore. The ores occur in nature as huge lumps. They are broken to small pieces with the help of crushers or grinders.
If the customer needs, we will collect relevant information, through the ball mill size and the properties of the ore and working conditions, based on the relevant information provided by the customer, with the help of the system analysis, will recommend you the suitable material of grinding ball and ball mill liners, which reduces the grinding production cost and improves the production efficiency.

Grinding and Flotation Fine ore at minus 19mm sizing is fed at a controlled rate into the open circuit 2600mm x 3960mm Hardinge rod mill at an average feed rate of 2,106 STPD or 87.75 STRH.
Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.
