用途及特点 Uses and characteristics：
● 该机采用鼓风方式使砂沸腾，砂子在两组高速旋转的磨擦盘之间相互搓擦，达到脱膜去尘目的。
The machnie uses blast to make the sａnd boil, and the sａnd rubs with each other between the two groups of high-speed rotating friction discs, so as to remove the dust and film.
● 在高温热法再生工况下，再生，并且具有冷却功能。
Under the condition of high temperature thermal regeneration,the regeneration effect is remarkable and has the cooling function.
● 主轴采用水冷设置在工作箱体两端外的轴承座，轴承等部件，避开了高温砂子和粉尘的影响，使用寿命长，设备运行可靠，是较先进的旧砂再生设备。
The spindle adopts water-cooled bearings, bearings and other parts outside the two ends of the working box to avoid the influence of high temperature sａnd and dust. It has long service life and reliable operation. It is an advanced old sａnd recycling equipment.
