The casting sand process mixes the required proportion of raw materials evenly to make mortar or green sand, and through full mixing and grinding, a heating and drying process is required later, and the whole production line process will also be interspersed with a lot of conveying equipment, such as bucket lifting, screw feeder, belt conveyor, etc., but they are only conveying equipment, and the effect on cooling is relatively small.
The temperature after drying the sand is not the same according to different sand molding processes, some of the sand comes out of the temperature is higher, and some of the sand comes out of 80-100, such as color resin sand, and then the finished product can be packaged for screening work, and the packaging user finds that the material temperature is basically still 60-70 after the bucket is lifted into the vibrating screen, and the last ton bag will be burned. If you buy a higher high-temperature bag, the cost of long-term accumulation will be very high, and it will take at least 7-8 hours to lift the material into the silo and wait for it to cool naturally, which can not be met under the very urgent production task of the order.
The vibration hoist is a way to improve the application of casting sand cooling, at this time, the dried sand is subjected to a simple cooling treatment, and does not delay the transportation, and combines the two into one, which not only saves the production line from adding an additional equipment, needs more space and other conveying equipment, but also saves the production line needs more space and later maintenance costs. The vibrating screw elevator can just meet this kind of cooling needs, reducing the temperature of the sand to below 60, but replacing the original bucket lift, the space layout does not need to change too much, and the maintenance cost has not increased.
