The determination of the distance between the impeller and the bottom of the tank is affected by many aspects. First, the distance between the impeller and the bottom of the tank should be such that after the Flotation Machine is stopped, the ore will not block the impeller after the slurry has settled for a certain period of time, and the flotation machine can start normally. This distance is related to the structural parameters of the flotation tank and the concentration and particle size composition of the slurry. The larger the distance, the easier it is to start, but the larger the distance, the easier the imbalance between the sinking tank and the slurry surface; the distance between the impeller and the bottom of the tank When the reduction is made, the maximum aeration volume of the flotation machine is reduced, and the ore particles in the tank are not easy to sink, but the suspension state of the ore particles in the flotation tank is deteriorated, stratification is liable to occur, and the flotation condition is deteriorated, and The wear of the tank tends to be severe. Therefore, it is very important to seek a moderate distance between the impeller and the groove bottom. The fluid in the flotation tank is a three-phase mixing system with a very complex dynamic state. In determining the impeller speed, it must be considered to meet the requirements of three aspects: the impeller stirring speed is greater than the critical speed required for solid particle suspension; the impeller stirring speed is greater than the required speed of the dispersed gas; the impeller stirring speed can not be too high to avoid the sorting area. And the role of the foam zone is undermined. In other words, it is to find an impeller speed that can meet the above three requirements at the same time, and the flotation machine can operate normally. After the impeller stirring speed is determined, it must be verified by experiment. In addition to meeting the above three requirements, the structural parameters of the impeller have a significant impact on the rotational speed. The well-designed impeller and stator structure can greatly reduce the impeller speed, thereby reducing the power consumption and spare parts consumption. More importantly, Can improve the technical indicators of the beneficiation process.
Small Raymond Mill,also called high pressure roller mill, fine power grinding mill, stone ginding mill machine. The grinding mill machine includes Ball Mill , raymond mill, Wet Pan Mill and rod mill machine. They are applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 mesh to 325 mesh according to requirements.
While the Ball mill can divide into 2 types, wet ball mill and dry ball mill. Ball mill is a mineral processing machine for milling the materials into powders after they are crushed. It is widely applied to the production of cements, silicate products, building materials, fireproof materials, fertilizers, glass, ceramics as well as nonferrous and ferrous metal processing industries.
