The cause of the "blowing" is mainly due to the increase in the amount of minerals and the change in the amount of water (water pressure) caused by the sharp increase in grinding concentration. The sound becomes dull, I can't hear the impact of the steel ball. Observing the ammeter can see the current drop, which means that the motor has the least work at this time, and the mill has lost the grinding effect. If not promptly adjust, and soon the cylinder body material will cause the loss of metal from the mine to the mill spit out (commonly known as lean pull).
Deal with the phenomenon of "swelling belly", the operator should not panic. It is necessary to first turn off the feeding machine, stop the feeding, and increase the amount of water in the rear of the mill. The discharge of the ore is appropriately reduced to increase the overflow concentration of the classifier. The purpose is to reduce the amount of returning and reduce the load on the mill. After careful treatment and adjustment, it usually takes about half an hour to return to normal, and some serious ones are still longer. When it is found that the discharge concentration of the discharge port is thinner and the discharge amount is gradually reduced, the sound of the steel ball striking the lining can be heard; the current meter can be found to return to normal, and these phenomena all indicate that the "flatness" has been solved. At this moment, the mine and other operating conditions should be restored to make the mill work normally.
A Heat Exchanger is a device designed to efficiently transfer or "exchange" heat from one matter to another. When a fluid is used to transfer heat, the fluid could be a liquid, such as water or oil, or could be moving air. The most well known type of heat exchanger is a car radiator. In a radiator, a solution of water and ethylene glycol, also known as antifreeze, transfers heat from the engine to the radiator and then from the radiator to the ambient air flowing through it. This process helps to keep a car's engine from overheating. Similarly, our heat exchangers are designed to remove excess heat from aircraft engines, optics, x-ray tubes, lasers, power supplies, military equipment, and many other types of equipment that require cooling beyond what air-cooled heat sinks can provide.
There are various types of heat exchangers. our heat exchangers provide air-to-liquid cooling, liquid-to-air cooling, liquid-to-liquid cooling, or air-to-air cooling. With air-to-liquid cooling, heat is transferred from the air to a liquid. One example of air-to-liquid cooling is cabinet cooling. With liquid-to-air cooling, the heat is transferred from the liquid to the air. This type of cooling is generally used to cool process fluids. Liquid-to-liquid cooling is also used to cool process fluids, but the heat is removed by another liquid instead of by air. Lastly, with air-to-air cooling, heat is transferred from one air or gas stream to another.
we has been manufacturing one of the most widely used heat exchanger technologies, tube and fin heat exchangers, for more than 20 years. Tube and fin heat exchangers provide air-to-liquid cooling or liquid-to-air cooling. They consist of fin, hairpin tubes, return bends to connect the hairpins, a tube sheet to support and properly align the tubes, a header with inlets and outlets, side plates for structural support, and usually a fan plate. The tubes provide the path for the liquid coolant, and the fin adds surface area for more heat convection. Copper is often selected for tube and fin material due to its excellent thermal conductivity and compatibility with water and ethylene glycol solutions. However, stainless steel is used for tube and fin when it's necessary for the coolant to be deionized water or other corrosive fluids.
