The ore drum screen is generally composed of a drum, a frame, a funnel, a reducer and an electric motor. In addition, different placement schemes can be designed for the equipment based on the production needs of the customer. When the mining drum screen is working, the crushed ore enters the drum from the feeding end. On the one hand, it will be affected by the centrifugal force generated by the rotation of the drum, and on the other hand, it will be affected by the jigging effect. The ore with a relatively large particle size will flow forward along the inclination of the drum. The ore with a suitable particle size will be screened out in turn according to the specifications when passing through the screen and fall into their respective funnels, and finally sent to the finished product pile by the belt conveyor.
Mica and quartz are common minerals that play an important role in mineralogy. Although they are both silicate minerals, there are clear differences between them. First, mica and quartz are very different in appearance. One of its distinguishing features is that mica exhibits a layered structure that can be easily peeled off into thin flakes. Quartz, on the other hand, is a uniform crystal with no layered structure. Additionally, mica is usually dark in color, such as black, brown, or green, while quartz is usually clear or white. Secondly, mica and quartz also differ in their physical and chemical properties. The hardness of mica is usually between 2.5 and 4, which is relatively easy to be scratched; while the hardness of quartz is very high, 7, which is a very hard mineral. In addition, mica has good refractive properties and electrical properties, while quartz is an excellent piezoelectric material.
