Vertical filter presses have a wide range of applications and a relatively simple structure. The pressing and pulling of the plates and frame, as well as the unloading and cleaning of the filter cloth, can all be automated, facilitating the expansion of filter presses into larger sizes. Plate and frame filter presses offer a simple structure and powerful functionality, meeting virtually all requirements. Belt filter presses continuously discharge the filtered residue through the filter cloth belt, ensuring continuous operation and high filtration efficiency. However, they are expensive and bulky. The filtered residue has a high moisture content, typically only around 45%. Chamber filter presses have an optimized structure, are reliable and durable, withstand high pressures, are highly automated, and are easy to operate. They also offer low operating costs. They utilize high-pressure, rapid pressing technology, shortening production cycles. Generally, no chemicals are required for mud,...

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, ...

 Drum screen: efficient separation of sand and gold Drum screen is one of the commonly used equipment in the process of gold panning, mainly used for the preliminary separation of sand and gold. Its working principle is to screen sand and gold particles through the rotation of the drum. The design of the drum screen usually includes multiple layers of screens, and screens with different apertures can separate particles of different sizes. This equipment is suitable for placer ore with high gold content, and can quickly remove large pieces of sand and gravel, leaving fine sand with high gold content. The advantages of the drum screen are simple operation and convenient maintenance, which is suitable for small and medium-sized gold panning operations.

The fully automatic river channel special sand screening machine is applicable to sand and stone separation, coarse and fine separation, sea sand and shell impurity screening, etc. Simple installation foundation: Because the entire equipment is a box-shaped frame structure, only a flat ground is required. Desalination and flushing method: Before flushing, the sea sand needs to be soaked in the fresh water soaking pool for no less than 24 hours, and then sent to the feed chute bucket by a loader. There are fresh water inlets on both sides of the chute bucket. Mechanical vibration is assisted by manual work to make the sea sand enter the cleaning drum under the continuous impact of fresh water flushing. The rotating stirring drum fully stirs and cleans the sea sand. The desalinated sea sand enters the grab bucket under the push of the built-in spiral blades of the drum, and is sieved through the discharge hopper and the discharge belt conveyor to screen out larger particles of impuritie...
