Mill experts about the impact on productivity of the mill speed

       Actual production, according to media movement theory to determine the appropriate operating speed milling machines are the critical speed of 76% and 88% while our current manufacturing mill transfer rate between the majority of 75% to 80%. Also suitable mill speed is determined by the temporary production compared. When comparing, do not just look at the level of the production capacity of the mill, but also the power consumption, steel consumption and economic benefits how. The results of a concentrator States on a series of 3200mm 3100mm ten temporary industrial scale ball mill speed comparison test was filling rate remained under 44% ~ 48% condition, ball speed by 18r / min speed was increased to 74.3% 19.8r / min speed was 81.72%, the whole plant in processing ore increased by 45,800 t but due to the increase in electricity consumption of 6.574 million kw h liners make more consumption 388.48t cost per ton of concentrate to improve the 0.38 yuan,Winnowing pulverizer Mill resulting in the whole plant all year speed is increased due to mill and less profit 567,900 yuan. That is, increasing output without increasing the conclusion is negative.
        Grinding media in a state of motion depends on the cylinder body mill speed. Motion state of the medium is different, when other conditions remain unchanged. Grinding effect is not the same. At low speed milling machines, medium spilled off the movement-based, High Pressure Grinding Mill small impact effect, mainly for grinding action grinding mill production capacity is low, suitable for fine grinding; at high speed, medium Paola sports increase the proportion of the way, the impact of the role of strong grinding effect to the impact of the main grinding stripping followed conducive coarse crushed material, milling machine high production capacity. Mill filling rate is different, the maximum useful power reaches the desired speed is not the same. Filling rate is higher, in order to ensure the innermost layer can be in the falling ball movement, requiring higher mill speed, ability to make useful power reaches the maximum, so that the mill has the greatest productivity.

Analysis Raymond run air volume and pressure of

         Resistance blower air drum person Raymond machine, airflow is material, it raises the material powder, hanging suspended roller axis movement, the movement of the blades of wind screen, pipes, etc., the pressure gradually turned negative from positive. Raising the mixed gas stream into the powder and the NPC cyclone gas, particles separated by large cyclone out into the hopper, to further reduce the air pressure, air particles separated by a blower and then people Raymond drum machine , airflow circulates in this closed system. Flow in the circulatory system pressure is different everywhere, and it is subject to change, the Raymond mill system
The air volume and pressure are shown in Table 3-2,Winnowing pulverizer Mill run-time pressure distribution shown throughout the mill pressure factors are: (1) the thickness of the mill at the bottom of the material layer; (2) the size of the feed rate; (3) mill speed; (4) analysis of machine speed and blade inclination. The so-called zero pressure surface (or zero interface), which is the air pressure within the system is zero (gauge) pressure of dots of the interface. Loop gas flow system, there are two zero-Lok surface within a blower, air from the negative pressure into the interface, the wind pressure of the blower is substantially stable. Another zero-machine interface in Raymond, from positive into negative air interface.
         Zero pressure surface is divided into the total pressure and static pressure surface zero zero pressure surface. The so-called zero-pressure side is full pressure surface pressure equal to zero by the whole point of the composition; and surface composition by hydrostatic zero point zero are called hydrostatic pressure surface. Total pressure and static pressure relationship is: H5 = ten Ad (3-8) at Raymond loop system, there is a certain distance between the total pressure of zero zero pressure both surface and hydrostatic pressure surface, the distance resistance is equal to the pressure within the total pressure and static pressure surface zero zero pressure difference between the surface. The whole concept of using zero-pressure side pressure is to facilitate the calculation, and the concept of using a static zero-pressure side piping to take in order to facilitate understanding of powder (take the wind) or leakage (people) wind conditions,High Pressure Grinding Mill in order to control operations. But in the face of mobile computing zero pressure, the pressure must use the full face of the whole concept of pressure and zero pressure. Total pressure and static pressure surface zero zero pressure surface always appear in pairs, if the zero-pressure surface moves, the other - a zero pressure surface will move with it. I duct resistance to determine the total pressure of zero pressure surface position, when I duct little resistance when running surface at zero pressure feed port below, generally do not need to move the zero pressure surface. By controlling the production should be more than duct flow (control over wind pipe gate) so that the entire surface pressure stable at zero pressure hanging roller and grinding ring (Rims) Department; duct when the air volume control than in Table 3-3 when the number of ranges, resistance not greater than the values ​​listed in Table 3-3, you can not move the zero pressure surface; remainder duct when using a large dust resistance, or because dust requirements, needs of the entire wind loop in the negative when working under the pressure of the state, the total pressure of zero pressure surface Raymond moved by the blower outlet nearby, and even moved into the blower.
