When the grinding machine “swellsâ€, the following phenomena generally occur: 1 The main motor ammeter indicates that the current is decreasing; 2 The grinding machine discharges a large amount of ore and the slurry is poured out; 3 The overflow of the classifier is “running rough†and the amount of sand returning is obviously increased; 4 The grinding machine is running quietly, and almost no sound of the steel ball can be heard. The phenomenon of "swelling belly" is the result of the imbalance of the working of the mill. Because of certain specifications and types of grinding machines, under certain grinding conditions, only a certain passing ability is allowed. When the nature of the ore is changed, or the amount of ore is increased or the coarse grain is added to increase the ratio of returning sand, because it exceeds the passing ability of the grinding machine itself, it will be “digestedâ€, that is, “expansion†occurs. The belly phenomenon. Then the improper operation will also cause the "flat" of the grinding machine. For example, improper use of grinding water has a direct impact on the grinding concentration, while excessive grinding concentration may cause "blowing". In addition, the total amount of grinding media or the unreasonable ratio of ball diameter can also cause "bloat". We know that the operation of the mill and the grinding of the ore require energy. The grinding machine has to work to overcome the resistance and friction generated by its own quality, so it needs to consume energy, but the power consumption of this part is generally small, and most of the energy is consumed in the ore grinding. During the mine. As the grinding machine "swells", the grinding effect is greatly reduced, so the mechanical energy of the electric energy conversion to grinding is greatly reduced, so the main motor current is degraded. From the perspective of the movement condition of the grinding medium (steel ball), as the grinding machine “swellsâ€, the material increases, the concentration increases, the height of the steel ball is lowered, and the grinding force is small, so the kinetic energy is reduced and the current is decreased. . In the case where the grinding machine is working normally, the current is large and the grinding efficiency is also high. First of all, we must analyze the change of ore properties, give the amount of ore, water supply, sand return, and overflow particle size normal, find out the reason, "the right medicine." The following measures can generally be taken in operation. (1) Reducing the ore supply of the grinding machine or stopping the feeding in a short time can reduce the working load of the grinding machine and reduce the amount of minerals passed by the grinding machine. (2) Adjusting the water consumption The grinding concentration must be strictly controlled. If it is too large or too small, it will have adverse effects. When the concentration is too high, the slurry flow rate is slow, and the impact of the grinding medium becomes weak. For the overflow ball mill , the size of the ore discharge becomes coarse, while the lattice ball mill may appear to be "flattened". (3) Reasonable addition of grinding media If the amount of media in the grinding machine is insufficient, the grinding medium of larger size should be properly supplemented. China leading manufacturers and suppliers of Forging High Pressure Vessel,Small Lined Pressure Vessel, and we are specialize in Pressure Vessel Tank,Steel Pressure Vessel, etc. The flange standards API 6A and ASME/ANSI B16.5 are similar dimensionally - but the API 6A flanges are rated for higher pressures. The difference between ASME/ANSI and API flanges is the fabrication material and the higher rated API operating pressure. API FLANGES are usually use for precision CNC turned components, CNC machined components, tractor parts, automobile components, hammer unions, API flanges, ball joint components, bearing housings, compression fittings, flow nozzles, gear blanks, coupling, etc. We are capable of manufacturing spare parts and CNC machined components in accordance with the customer's cost, delivery, and quality and performance expectations.
