The  flotation separation  process has become one of the most important mineral processing methods in the world. And the  flotation cell , important equipment in the flotation separation process, can be divided into two categories: mechanical flotation cell, flotation column and reactor/separator flotation equipment. But at present, mechanical flotation cell is widely used in the flotation separation plant, and the impeller system is one of the important working components of the mechanical stirring flotation cell, which is the core of the flow component. According to the direction of the liquid flowing out from the impeller, the impeller of the flotation cell can be divided into three types: centrifugal flotation impeller, mixed-flow flotation impeller and axial flotation impeller. However, due to long-term exposure to flotation reagents and slurry erosion, the flotation impeller become one of the vulnerable parts of the flotation cell, which makes some important para...

In the production, the methods used for the  extraction of iron from haematite  are not single, mainly include the froth flotation method, magnetic separation method, gravity separation method and roasting magnetic separation method. 1. Extraction of iron from haematite: Froth flotation method The  froth flotation method  is mainly used for the extraction of haematite with fine and micro-fine weak magnetic ore, including positive flotation method (positive flotation of anionic collector) and reverse flotation method (negative flotation of cationic collector). • Positive flotation method Haematite positive flotation method is a method used for the extraction of iron from haematite, which uses anionic collectors to float iron ore from raw ore. It can achieve discarding tailings under the coarse particles without desliming. Haematite positive flotation method is featured with a simple dosage, low processing cost, which is especially suitable for the extractio...

According to the different crushing principle and particle size of size, the   types of crusher   is divided into many kinds and a variety of new types of crusher have been widely developed, mainly including jaw crusher, cone crusher, impact crusher, hammer crusher, mobile crusher. 1.   Jaw Crusher A jaw crusher is a type of crusher comprised of two jaw plates. One is a fixed jaw plate that is vertically fixed on the antetheca of the body, and another is a moving jaw plate, forming a crushing cavity with a fixed jaw plate. During the working of this type of crusher, the moving jaw does a periodic motion to the fixed jaw surround the eccentric shaft. When it closes, the materials are crushed by the action of squeezing and impact; on the contrary, the crushed materials are discharged by the gravity from the discharge opening. The crushing cavity of jaw crushers is deep without dead zone, so the feeding capacity and production of this type of crusher have been greatly...

Magnetic separation   is a common mineral processing method, which realizes the separation in the uneven magnetic field of magnetic equipment according to the magnetic differences among various minerals. Therefore, it is very important to select suitable magnetic equipment to achieve the ideal magnetic separation effect. Here are the types and applications of magnetic equipment in mineral processing. 1. Types of   magnetic equipment In recent years, magnetic equipment has been developed rapidly, and became larger in equipment scale and diversified in structure form. There is various magnetic equipment structure, so the classification methods are also diverse. (1) According to the different bearing medium, the magnetic equipment is divided into   dry magnetic equipment   and wet magnetic equipment. Dry magnetic equipment completes the magnetic separation in the air, while the wet magnetic equipment finishes the magnetic separation work in the water or magnetic ...

Screen machine is a common   mineral processing equipment   in industrial production. Due to various factors during the working process, the screen machine may be subject to various damages and failures. Here are some common problems and related solutions of the   screen machine . 1. The material above the Screen Machine Flows Abnormally There are two possible factors in this situation. One is that the anti-deformation ability of the screen machine box is not enough, that is, the rigidity of the screen box is insufficient, and the connecting bolt may be loosened, or it may be severe to fully loosen, tightening the connecting bolt can solve this problem. The other factor is the problem happens to the horizontal level of the screen box. This problem can be solved from the support base of the support spring or the support spring itself and by replacing the spring or adjusting the size of the support base. If there is no problem with the support base, it may be a horizon...

At present, there are a lot of ball mill manufacturers on the market, and the   types of ball mill   are also different. In the face of so many types of ball mills, how should we choose the ball mill? The common types of ball mill used in the mineral processing mainly include cement ball mill, tubular ball mill, ultra-fine laminating mill, cone ball mill, ceramic ball mill, intermittent ball mill, overflow ball mill, grid ball mill, wind discharge ball mill, double bin ball mill,   energy-saving ball mill . But the types of ball mill are also varying according to the different sorting conditions. 1. According to the shape of the ball mill cylinder (the ratio of length to diameter), the types of ball mill can be divided into: • Short cylinder ball mill: the cylinder length(L) is less than two times of the cylinder diameter(D), that is, the ball mill with L≤2D is the short cylinder ball mill. It is usually a single-bin structure, mainly used for coarse grinding or fi...

In mineral processing plant,   vibrating screen   is one of the common classifiers, which has large influence on the following works. Therefore, how to improve the screening effect is one of important problem to be concerned. In this paragraph, we will analyze what the factors are and how they influence the vibrating screen. There are many problems influences the screening effect of vibrating screen. The most important ones are the characteristics of the screening material, the screen surface parameters of the   vibrating screen , and the motion parameters of the vibrating screen. Next we will analyze them one by one. 1.The characteristics of the screening material Different materials have unique characteristics in density, hardness, moisture content and other aspects of the difference. Generally speaking, the screening effect of materials with higher hardness and brittleness is better than those with lower hardness and brittleness. For sieving materials, there are...
