罩壳上设有抽风口，可强力通风，随抽风带走大量湿热空气，有效控制旧砂含泥

There is an exhaust port on the cover, which can ventilate strongly, take away a large amount of hot and humid air with the exhaust, and effectively control the mud content of the old sand. This fine hexagonal screen has a long screen and a length-to-diameter ratio of 3 (old-fashioned drum screen is about 1.5-2). The hot and humid old sand is evenly spread during screening, so that the hot and humid old sand can achieve a certain cooling effect.

The hood is equipped with an air outlet for strong ventilation, which takes away a large amount of hot and humid air with the exhaust, so as to effectively control the mud content of old sand. The fine hexagonal screen has a long screen barrel and a length diameter ratio of 3 (the old drum screen is about 1.5 ~ 2). The wet and hot old sand is evenly distributed during screening, so that the wet and hot old sand can achieve a certain cooling effect.<br>

The hood is provided with an air exhaust port, which can strongly ventilate and take away a large amount of hot and humid air with the air exhaust, thus effectively controlling the mud content of used sand. The fine hexagonal screen has a long screen barrel and a length-diameter ratio of 3 (the old drum screen is about 1.5 ~ 2), and the wet and hot used sand is evenly distributed during screening, so that the wet and hot used sand can achieve a certain cooling effect.
