The sieving efficiency refers to the ratio of the weight of the under-slung product actually obtained at the time of sieving to the weight of the granules which is smaller than the size of the mesh in the sieving material, and is generally expressed as a percentage. Calculation formula E=[100(ab)]/ ....
[ Instrument Network Instrument R & D ] In recent years, the adaptive optical system has continuously increased the requirements for dynamic real-time measurement to better adapt to the fields of high-energy lasers, astronomical observations, and optical communications. Recently, Zhang Junyong ....
The amount of air entering the slurry depends on the type of flotation machine used and its operating system. For the three types of mechanical agitating, mixing and airlifting flotation machines, the air required for flotation is minimized by mechanical agitation. The amount of aeration of the mech ....
The computer-aided drawing of the mine map is essentially based on the specific requirements of the mine map drawing. With the support of the computer database and the drawing software, a special mine map drawing system is developed to complete the automatic drawing process of the mine map. The comp ....
