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.

Coal slime dryer is a drying equipment with mature technology and effective reduction of coal slime moisture content. It is suitable for drying coal slime, raw coal, flotation clean coal, mixed clean coal, various metal concentrates, waste slag, tailings and other materials in the coal industry, and has strong applicability to various high-humidity and sticky materials. The daily output of a single coal slime dryer production line can reach more than 100 tons. Zhenneng Energy equips the coal slime dryer with multi-stage dust removal equipment, which can effectively solve the problem of waste gas treatment and meet local environmental protection standards. The dried coal slime can be combined with the company and the surrounding conditions, and cooperate with power plants, brick factories, cement plants, incineration plants, etc. to achieve comprehensive disposal and utilization of coal slime (such as domestic fuel, power plant fuel, brick factory additives, cement additives, etc.

Detailed explanation of iron removal methods in bauxite 1. Physical method The physical method is to remove iron from bauxite by using the difference in physical properties. Common physical methods include gravity separation, magnetic separation and flotation. 1. Gravity separation: Utilize the difference in density of different minerals to carry out mineral separation through equipment such as shaking tables and chutes. The density of iron minerals in bauxite is relatively large, and some iron minerals can be removed by gravity separation. 2. Magnetic separation: Utilize the strong magnetic characteristics of iron minerals, and magnetic separation can effectively remove iron minerals. Magnetite is common in bauxite, and magnetic separation can be used to separate them from bauxite. 3. Flotation: Utilize the difference in surface properties of different minerals, adjust the surface properties through flotation agents, and separate bauxite from iron minerals. In the flotation process, ...
