The choice of bauxite mill should be considered from a technical perspective

The complete set of bauxite mill includes hammer crusher, bucket elevator, storage bin, vibrating feeder, mill main machine, frequency classifier, double cyclone powder collector, pulse dust removal system, high pressure fan , air compressors, electrical control systems.

At present, there are many kinds of bauxite mills commonly used in the market, and the principle is generally divided into three types: the first type is high-speed hit type, the second type is low-speed roll type, and the third type is self-shock type. . Different processing methods are selected according to the different uses of bauxite. The pulverization fineness of bauxite is very different, generally 80-200 mesh, and 400 mesh is also required. 80-200 mesh bauxite usually adopts air-selective pulverizer or ordinary Raymond mill. The principle of two kinds of equipment for milling is high-speed striking and low-speed rolling. The output is not too different, mainly because of the difference in performance, stability and maintenance rate of the machine. In contrast, the use of ordinary Raymond mills accounts for the majority of the market. Raymond mill speed is usually less than 300 rev / min, small Raymond mill 1410 rated speed is 240 rev / min, the output is about 300 kg / hour; 2615 Raymond mill rated speed 160 rev / min, the output of 1200 kg / hour Left and right, of course, there are more models, the output is also different, here is not introduced one by one.

What should be considered in the technical level of the bauxite mill? 1. Select the bevel gear drive, the bevel gear drive, the structure is more compact, the installation adjustment is more convenient and efficient, and the efficiency is greatly increased. 2. The internal thin oil lubrication system is selected, and the lubrication of the main shaft bearing and the tapered gear shaft bearing can be realized without a fuel pump or a lubrication station. 3Adopting curved air duct, this curved air duct has smooth tangential airflow inlet and low resistance. The inner outlet direction is conducive to material dispersion and is not easy to block material. 4, choose to load 1500kg high-pressure spring device on the grinding roller device, the output is increased, the life is increased, which is very suitable for the grinding process of bauxite raw materials and clinker.
