Iron Ore Ball Mill

Steel is the main material of industrial machinery manufacturers. Before smelting, we must use some ways to reduce ore particle size, to sufficiently dissociated ore mineral. Iron ore grinding is completed in the ball mill, so the Iron ore ball mill is the main place for ore materials.

Just like other ball mills, the Iron ore ball mill is mainly composed by a feeding part, an exhaust end, a rotation, and transmission part(a reduction box, an electrical machine, an electronic control, and pinion drive gear) and other parts. Iron ore ball mill in accordance with its specifications can be divided into single warehouse and multi-warehouse, the greater of the ball mill the more warehouse, and every warehouse is separated by a plate. Due to different grinding time, the ore particle size will tend to be small from the feed end to the discharge end. Therefore, the diameter of steel balls is different in the different grinding room. The diameter of steel balls near the feed end is bigger than near the discharge end. The impact of steel balls downward movement can help ball mill to complete the mill work. Ball mill relies on the motor and decelerator to drive small gear, and the cylinder is drove by the mesh of pinion and ring gear. In the interior of the ball mill cylinder, according to the specific requirements and nature of ore, there are different types of liners. The liner of Iron ore ball mill is mainly high manganese steel and wear-resistant rubber. The liner of ball mill can protect the cylinder and effect the movement of steel balls. Rough surface liners has high steel balls lifting capacity, which can lift steel balls higher so that the steel balls have a greater impact energy. This liner is suitable for kibble. The smooth surface liner has opposite situation. Between the steel balls and liner has more relative movement, and this liner is suitable for finely ground. Iron ore ball mill uses different properties liners according to specific grinding requirements. The grinding fineness ore will go to next grinding compartment to further grinding and the fineness ore discharged from the discharge end of a ball mill to complete the job.

Iron ore ball mill is the major mining processing equipment today, after a number of improvements, on its basis depending on the grinding required to produce a number of different models. The grinding operation of Iron ore ball mill has been very mature, and its stable performance is why it has widespread promotion.
