Product Description

The working principle of the hammer mill is that the material enters the crushing bin, and the powder is impacted by the high-speed rotating grinding knife, mainly by the impact effect to crush the material. The material enters the hammer mill and is crushed by the impact of the high-speed rotating hammer head. The crushed material obtains kinetic energy from the hammer head of the hammer mill and rushes to the baffle and screen bar in the frame body from the high-speed. At the same time, the materials collide with each other and are crushed many times. The materials smaller than the gap of the screen bar are discharged from the gap. Some larger materials are impacted and ground by the hammer again on the screen bar, extruded and crushed, the material is squeezed out of the gap by the hammer head of the hammer breaker to obtain the product of the required particle size. The feed inlet is equipped with a star-shaped blanking valve to control the blanking speed and prevent dust from being generated during the crushing process.

工作原理

螺旋式气流粉碎就是高速气流以切线方向带动物料在研磨腔内相互撞击,剪切等综合作用力下使物料破碎。压缩气体经拉瓦尔喷嘴瞬间释放后,产生吸热效应,带走粉碎过程中产生的热量,使物料在低温环境下实现粉碎。

进料

待粉碎的原料通过加料器均匀送料,物料通过进料口端射入的气体产生负压被吸入,将物料喷射进入研磨腔。

 

研磨

粉碎室周围的喷嘴产生的超音速沿设定切线方向射入粉碎室,气固两相流形成高速旋流,物料沿切线方向在腔体内高速旋转,使得物料之间相互撞击、摩擦,将物料磨碎。物料在粉碎腔内高速旋转时,物料粒子之间相互摩擦,通过粒子对粒子的相互撞击、摩擦。使得物料粒子会越来越小,粒子大的物料由于离心力大而会在研磨腔的内壁边缘继续做高速旋转相互摩擦,随着物料粒子的减小,离心力也会减小,粒子同时也会向研磨腔中心移动,当离心力小于中心出料口气流产生的力时,物料将会随着气流带出出料口。

 

收集

离心力的作用会让较大的颗粒在粉碎腔外围运动,而较小的颗粒随螺旋气流逐渐向粉碎腔中部靠拢,被粉碎后的超细物料,超细颗粒因失去质量而失去离心力,脱离旋流场。在压差作用力下通过中间的出料管道进入旋风分离器,大部分物料向下运动进入储料容器中,气体向上排出。
