silica gel machine processing lubrication system: according to the behavior and the use of different media, mill process lubrication system pressure 0.4-1.8MPa often about flow per minute can be as large as several hundred to several thousand liters, media filtration accuracy of less than 5μm. Common sub-cooling nozzle and jet to roll the media Kun and rolled on to the exhaust of pressure, temperature and other strict requirements. Therefore, emission of media, oil (medium) liquid temperature from the pressure, temperature control valve.
