To date, the domestic common sand dryer, mostly angular tower dryer and hot sand sand dryer mesh cylinder type. These two effects are very similar advantages dryer lees dryer manufacturers, all with precipitation rate, less one-time investment, small footprint, sand color after drying and good. Basically represents the direction and level of development of the dryer. While it is undeniable that our dryer has advantages over lees dryer features, but its foreign advanced dryer and there is still a lot of drawbacks. No drying yield production record recording system drying system is extremely important, and domestic dryers generally do not have this equipment, are piled up in the sand after the yield calculation, so the class can not distinguish between the yield of production. Over time, it will seriously affect the workers' enthusiasm for production, will result in the production of non-serious inspection, when equipment maintenance is not serious overhaul, often unplanned downtime and repair equipment, evening fireman fireman who are not serious, slow drying medium temperature go up, in order to Ultra-bake sand so the water does not drain after secretly reduce engine speed sand, debris and dryer outside the network board for a long time no one to clean up, a serious impediment to discharge sand precipitation and exhaust. Installing drying yield recording system, in order to improve work efficiency, shorten the drying time, reduce drying costs.
