Ball mill characteristics
The ball mill can be divided into vertical and horizontal. Vertical stirred ball mill,alluvial gold mining equipment due to the new design, compared with the roller ball mill, with its own unique advantages. Motor-driven vertical deceleration, by the rotation of the coupling to drive the rotor grinding device, suspension grinding media ball, abrasive, and water mixture. The equipment during the operation, the barrel is fixed does not move, just stirrer play a strong role, and they can be used to test the samples in the case of stopping the machine and add the abrasive. Ball mill at the bottom of the filter system to test the abrasive whether to meet the specifications, in order to re-grinding of large particles in order to achieve the need for grinding and dispersion.
The ball mill can be divided into the mixing equipment and grinding balls.
Ball mill mixing equipment
Mixing can use two or more different substances in each other, scattered among each other,antimony ore beneficiation plant so as to achieve uniform mixing; can also speed up the process of heat and mass transfer. Example of the mixing operation is quite common, for example, some salts in aqueous solution was prepared in the laboratory, in order to accelerate the dissolution, often with a glass rod in the liquid in the beaker for mixing. Another example is the order to prepare a suspension, will use the liquid in the glass rod continuously stirred vessel, the solid particles do not sink in, and keep it suspended in the liquid state. In industrial production, the mixing operation is started from the chemical industry, focusing on food, fiber, paper, petroleum, water treatment, as part of the industrial processes have been widely used [12].
In industrial production, most of the mixing operation, Department of Mechanical stirring, mixing equipment, mainly by the mixing device, shaft seal, and the mixing tank has three major composition. Among them, mixing equipment is divided into: gear, mixers, mixing shaft; mixing tank is divided into: two kinds of tanks and accessories.
(A) mixing equipment in the industrial production.Mixing equipment, a wide range of applications in industrial production, especially in the chemical industry, chemical production or application of the mixing operation. All the chemical changes in the chemical process, is to participate in the full mixing of the reactive substances as a precondition for the physical changes of the heating, cooling, and liquid extraction and gas absorption process, often mixing operation in order to get good results. Mixing equipment on many occasions as a reactor applications [12]. The reason for this wide range of applications mixing equipment, mixing equipment operating conditions (such as concentration, temperature, residence time), controlled a wider scope, and can adapt to a variety of production.
The role of the mixing equipment is nothing more than: (1) the material uniformly mixed. ¢Ú the gas well dispersed in the liquid phase. (3) solid particles uniformly suspended in the liquid phase. ¢Ü make another immiscible liquid uniformly suspended or emulsified. The ¢Ý strengthen and white mass transfer. ¢Þ enhanced heat transfer. The case of homogeneous reaction, a mixture of speed, uniformity and heat transfer is good or bad, will influence the effect. As for the non-uniform system, also affect the size of the phase interface and interphase mass transfer rate, the situation is even more complex, stirring a change of circumstances, often very sensitive to the quality and quantity of the product. If the mixing conditions are not good, it will cause the decline or local overheating of the heat transfer coefficient, so that the material is dispersed unevenly, affecting the quality of the product,artificial sand making machine it tends to lead to the wall material viscosity, the reaction can not be good.
