用途 Use：
主要用于铸造车间树脂砂和水玻璃砂的再生。
It is mainly used for regeneration of resin sａnd and sodium silicate sａnd in foundry shop.
特点 Characteristic：
● 旧砂落到高速旋转的拋砂盘上，在离心力的作用下作径向加速运动，被抛出的砂子和耐磨挡砂圈及砂粒之间互相撞击、摩擦，从而使砂粒表面的惰性膜破碎脱落，并和微粉一起经抽风口排出，达到再生的效果。
The old sａnd falls on the high-speed rotating sand-throwing tray and accelerates radial movement under the action of centrifugal force.The sａnd thrown out collides and rubs with the wear-resistant sand-retaining ring and sａnd grains,which makes the inert film on the sａnd surface break off and discharges with the fine powder through the air outlet to achieve the effect of regeneration.
● 根据工艺要求不同，可选择单级使用或多级组合使用。
According to different process requirements, single stage or multistage combination can be selected.
● 结构紧凑，使用可靠。
Compact structure and reliable operation.
● 砂粒破碎少，脱膜率高、再生效果好。
The sａnd is broken less, the film removal rate is high,ａnd the regeneration effect is good.
● 机体设有检修门，便于机器检修。
The body has a maintenance door to facilitate machine maintenance.
