Do you know the vibration device of the thickener?

Image
 The thickener is a solid-liquid treatment equipment used in the concentrator. In order to improve the treatment effect of the thickener per unit area and improve the efficiency of the thickener, the high-efficiency thickener or the inclined plate thickener will be selected. High-efficiency thickeners will increase the height of the straight wall section of the thickening tank, and use appropriate fabrics to add flocculants to improve concentration efficiency. In some concentrators, the materials are small and viscous, the sedimentation speed is slow, and the flocculant cannot be used due to the nature of the material. At this time, the inclined plate thickener is used. The thickening pool of the inclined plate thickener will be divided into a number of equally divided sectors, and each sector will be arranged at a certain interval into a certain angle of inclined plate or inclined tube. The fine particles of the material in the lower part of the thickening tank will naturally settle

What factors can cause the flotation machine to not work normally?

 The flotation machine is a full-grain flotation machine , suitable for both coarse and fine particle separation. After the Chinese pulp of the GLF flotation machine is processed, the flotation machine must be agitated and aerated, so that the mineral particles can be fixed on the bubble and float to the surface to form a foam product, and the rest will be stored in the pulp for separation . The GLF flotation machine is not only a stirring device, but also capable of forcibly blowing in air under the external special action. The mechanical stirring device is used to agitate the slurry to distribute the air flow, and the aeration and stirring of the slurry work separately. The GLF type aerated stirring flotation machine can be adjusted according to its own needs at best. Only in this way can it be helpful to improve the sorting capacity and processing capacity of the flotation machine. However, due to the larger processing capacity and the shallower flotation cell, the required power co

How to use large flotation machine to separate copper and molybdenum ore

 About 90% of non-ferrous metal recovery in the world will use flotation method, in order to realize mineral flotation flotation machine plays a great role. Large-scale flotation machine can significantly improve the processing capacity of beneficiation, reduce consumption, and obtain higher benefits. The flotation machine is a motor that drives the rotating shaft to rotate the impeller. Under negative pressure, the pulp moves between the impeller and the stator, and the centrifugal blower is evenly dispersed in the air through a porous cylindrical air distributor for mineralization. After the stator is stabilized, it rises to form a stable foam layer, and enters the next operation through the upper foam tank. The remaining slurry will flow through the flow holes in the tank wall to the next tank for sorting, and finally become tailings. The main characteristics of tooth decay of the super large flotation machine are: (1) The pulp aeration and bubble mineralization effect is good. The

Research on unit consumption and service life of ball mill liner

Image
 The liner is a key easily damaged part for the ball mill. The unit consumption and service life of the liner are inseparable from the working efficiency of the ball mill .      The factors that affect the wear rate of the liner mainly include the corresponding particle size and hardness of the material to be ground, how much electricity is needed to grind each ton of material, the diameter of the mill and its speed, the structure of the liner and the wear resistance of the liner material The percentage of the weight and volume of the original lining board and the original lining board. For the current process, the metal liner is mostly low-grade ore first-stage grinding, but for most low-grade ore, the content of silica and other hard grinding and corrosive minerals are very high, but in this case In the second-stage grinding process, many concentrators will choose ball mills to use rubber liners.      The service life of the cylinder liner is four factors: macroscopically speaking, t
