This product fits for recycling resin bonded sand and used sand and it is made of two groups rotors with high rotating speed and scraper with low rotating speed . while working , the rotors with high rotating speed and scraper with low rotating speed will cooperate with each other to strike , cut , extrude and rub the sand to break and make the inert film to fall and to make the sand be recycled after separation by wind 该系列产品主要用于树脂砂旧砂的再生，它的工作结构是由两组高速旋转的转子和低速转动的刮板组成，工作时，高速旋转的转子与低速转动的刮板配合，对砂子施以冲击剪切积压和搓擦，使砂粒表面的惰性膜破碎脱落经过风选分离，达到再生目的。
Discharge - sand gate offers double disk cooling system creditable condition for low temperature ; when sand temperature is very high , it can change the way of discharge - sand gate into intermittent type : put rating sand to double disk and spray water for falling temperature until temperature falls designed range ; open the discharge - sand gate and discharge sand ; and then takes anther cycle ; this type has good effect after real testing , which is the effective way for exerting cooling function of double disk 卸砂门这种控制方式给双盘冷却系统的可靠降温提供了条件,当型砂温度较高时可将卸砂门改成间歇式的，先将双盘内加入给定的砂量，喷水后直到温度降到给定的范围后，卸砂门打开将砂子卸出，然后进行下一循环，这一方式经实际运行验证效果良好，是充分发挥双盘冷却作用的有效途径。
It can make sprinkler of water feeding install on strap or on sand inlet of double disk and adjust spraying angle of sprinkler according to real condition ; the water will spray on falling sand that makes it form sand curtain ; it sprays water on hot sand equably and extends exchanging time of water and hot sand . 4 根据现场情况，加水喷头可设在进砂皮带上，或设在双盘的进砂口处，调整喷头的喷洒角度，使水喷向由下落的砂子组成的砂帘，将水尽可能预先均匀得喷洒在热砂上，增加水与热砂的有效热交换时间。
