Yield spiral classifier What factors? Yield how decisions spiral classifier mainly based on speed and width of the tank spiral classifier to decide that it was how the decision? Spiral speed should meet in order to send the settlement with grit. Speed ??grader faster the ball screw shaft, the stirring effect of pulp stronger, more entrained coarse overflow product. In order to obtain a thicker handle overflow and faster than the major settlement material, the spiral speed can be increased, but not too large, so as not to destroy the grading effect. But for secondary grinding or grinding cycle used in the classifier, the screw speed should try to slow down some. In the spiral classifier generally used in low speed stirred ball mill, especially for large spiral classifier. For example, to obtain a crude overflow, 2m diameter screw speed can not exceed 6r / min, generally more than 1m in diameter screw speed should be controlled at 2 ~ 8 r / min. The width of the trough overflow discharge speed has a lot of products, wide trough the overflow discharge speed and, therefore, the greater the likelihood of coarse discharged with the overflow. But on the other hand, the wider the ore trough of the greater size of the settlement, easy settlement. Therefore trough of width on grading effect is not great, but with the processing power is closely related grader. The width of the trough, there is a large processing capability. Conversely cone ball mill, processing capacity is small. Therefore, the width of the groove grader should be the size of the mill processing capacity to adapt. Spiral classifier beneficiation process is an important device, which is widely applied to various ore beneficiation operations, improve mineral production is an important device. If the user needs related to direct contact to learn more about the structure of our spiral classifier mechanical flotation machine flotation machine in most modern are equipped with blade impeller, which can be divided into two categories: the first category of impeller, planar projection is a large disk, above and below it (or just one side) radial distribution of the vertical blades that are not too high, straight or curved blade; the second category but the number of impeller close to the hub of vertical or inclined blade (Wei Muke flotation machine, Humboldt - Wei Dake flotation machine, Outokumpu flotation machine, Doyle - Oliver flotation machine, etc.). The main difference lies in the shape of an impeller vane blade, the shape of the blade for the second type of impeller is varied. With radial impeller also uses the stator and rotor majority flotation machine - stator (impeller - guide vanes) components are placed in the flotation tank, mostly near the bottom position, such as Outokumpu flotation machine, Doyle - Oliver flotation machine, Metso flotation machine, Michalis Noble flotation machine, PHBC flotation machine. As shown in Figure 1. The rotor is mounted on a small number of high, as 维姆科 flotation machine, as shown in Figure 2, or installed in the middle, such as the US company's PFE mineral flotation machine. In all of the above flotation machine we have implemented all the pulp mill must in principle beneficiation cycle through the impeller, and there the upper loop is an extremely important factor. It can carry out supplementary mineralized foam, but also maintain optimal distribution of the solid state in the tank volume, low energy consumption and therefore fall from the sky.
