High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% 10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.

The mineral marcasite, sometimes called " white iron pyrite ", is iron sulfide (FeS 2) with orthorhombic crystal structure. It is physically and crystallographically distinct from pyrite, which is iron sulfide with cubic crystal structure. Both structures contain the disulfide S 22− ion, having a short bonding distance between the sulfur atoms.

Marcasite itself is a granular stone with relatively low hardness (6 to on the Mohs scale) and a very distinct cleavage. That, together with its brittle nature makes it quite unsuitable for most jewelry purposes. Notice the marcasite work in these earrings. See them here. As a result, most marcasite jewelry actually contains pyrite.
