Some users may not understand the closed-circuit grinding mill manufacturers mill production line in what, in fact, closed-circuit grinding process will help improve the efficiency and quality. Reason: reasonable grinding process should the mineral particles ground to monomer separation should quickly from the grinding machine flush out. One hand, this can be avoided through the mill grinding media (balls), on the other hand can fully act on the coarse mineral particles, so that the energy to do useful work. Existing grinding machine to be material particle size classification is very difficult this classifier mill or fine sieve minerals qualified size fraction was separated coarse return grinding machine grinding (also known as sand back). Seen in closed-circuit grinding, grinding machine to mine is new to the mine plus sand back through the material of the grinding machine on the acceleration of the material by the speed of the grinding machine. By grinding a short time. Closed circuit grinding, trying to force the the unqualified coarse repeatedly until grinding to pass up through the grinding machine. Followed by closed-circuit grinding into a lot of grit to the grinding machine to the compound coarse-grained level content increased. According to the principle of grinding dynamics. In this case the maximum energy for useful work, so the speed of the grinding mill productivity gains. In addition, due to the presence of the right amount of sand back, you can eliminate the grinding machine new to the volatility of the mine produces product granularity. Visible, closed-circuit grinding can effectively avoid the smash and ran rough "phenomenon. It enables the grinding operation to ensure that qualified granularity premise uniformly coarse the narrower-level product, the the sorting operations next step is favorable. In addition, Raymond mill operation should be noted that the operation of the mill should be noted; mill speed should be controlled properly; milling raw material concentration to be appropriate, too high and too low is not good, the actual operation to pay attention to the regulation of the amount of water.
