21-03-2015· Understanding Pellets and Pellet Plant Operations. Pelletizing is an agglomeration process which converts very fine grained iron ore into balls of a certain diameter range (normally 8mm to 20 mm, also known as pellets. These pellets are suitable for blast furnace and direct reduction processes.

One contribution to minimise the increase is to use more efficient comminution equipment. Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here.

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.

Maintenance costs for roller mills are generally higher on a per ton basis, typically ranging from $0.05 to $0.09 per ton depending on the size of the machine and the finished particle size required. The cost of recorrugation is the most significant factor accounting for 60 to 70% of the total maintenance cost.
