气流

Material is ejected into the crushing chamber by means of high speed ejection flow formed by high pressure air through charging ejector, and the crushing nozzle outside ejects high speed air flow into the crushing chamber at a certain direction, making the material severely collided and frictionated therebetween and thus crushed .

该机是靠高压气体通过加料喷射器所形成的高速射流，使粉碎原料被射人粉碎室，粉碎室外围的粉碎喷嘴，有方向性的向粉碎室喷射高速气流，使物料间产生激烈的碰撞，摩擦而获得粉碎。
