The partialcavity consists of two horizontal adiabatic surfaces, a vertical hot surface and a cold surface with varied opening.
方形空腔由两个水平绝热壁、一个竖直加热壁而另一个竖直壁为冷壁但具有变化的开口度组成。

The increase of the cavity volume makes partial materials realize the air impact, the unbroken parts of which enter into the grinding zone and become fine powder after many times of impact.
容积腔增大，使部分物料实现了空中打击，其未破碎部分经过多次打击后进入研磨区形成细粉。
