Choose suitable crusher based on material hardness

Mechanical properties of ore has a great impact on the grinding, we have no reason to ignore it, but also cannot be content to know wear resistance coefficient and Platts hardness coefficient even if the ore. The ball mill professional scientific research experiments confirmed that, if the determination of ore crushing performance parameters is a reasonable choice of precondition of sodium ball size, for this is where the grinding. According to the mechanical properties of ore to the scientific selection of grinding conditions, also can have the grinding effect is good.

Influence of aggregate properties are largely grinding mill, mineral and ore general mechanical properties are hard and brittle, so the aggregate power consumption of large ground. Toughness ore also difficult to grind, the effect of impact crusher is not good, good shear grinding effect. The cleavage phenomenon in ore hardness decreased. Easy to grind: structural defects in the ore, whether macro or micro cracks reduce strength to ground.

When the ore in the large amount of mud, especially containing colloidal mud many minerals, easy to make slurry of too large, difficult to flow and discharge mill, cone mill productivity effect. The existence of a large number of some lamellar and fibrous minerals in the ores are also affecting grinding, they are easy to play into lamellar or fibrous and hard ground. Also, such as coal and talc class, hardness is low, but in the grinding of the slide and not easy to be engaged, hard ground, their work index may greatly exceed hard ore.

Influence of aggregate properties are largely grinding mill, influence of aggregate properties of grinding ball mill is the main mechanical properties of ore, including hardness, toughness, cleavage and structural defect. Ore hardness is difficult to grind, hardness is small, easy to wear. Hardness by mineral crystal thickness in ores and mutual bond strength decides.
