超微粉碎机的生产采用的是什么原理?

超声波发生器和换能器产生高频超声波。超声波在待处理的物料中引起超声空化效应,由于超声波传播时产生疏密区,而负压可在介质中产生许多空腔,这些空腔随振动的高频压力变化而膨胀、爆炸,真空腔爆炸时产生瞬间压力可达几千乃至上万个大气压。因此真空腔爆炸时能将物料震碎。
Ultrasound generators and transducers produce high-frequency ultrasound. Ultrasound causes ultrasonic cavitation effect in materials to be treated. Because of the dense area generated by the propagation of ultrasound, negative pressure can produce many cavities in the medium. These cavities expand and explode with the change of high frequency pressure of vibration. The instantaneous pressure can reach thousands or even tens of thousands of atmospheric pressure when the vacuum chamber explodes. Therefore, when the vacuum chamber explodes, the material can be shattered.
另一方面由于超声波在液体中传播时产生剧烈的扰动作用,使颗粒产生很大的速度,从而相互碰撞或与容器碰撞而击碎液体中的固体颗粒或生物组织。超声粉碎后颗粒粒度在4um以下,而且粒度分布均匀,但生产能力较低。
On the other hand, because of the strong disturbance caused by ultrasonic wave in liquid, the particles produce a great speed, and then collide with each other or with the container to smash the solid particles or biological tissues in liquid. After ultrasonic grinding, the particle size is less than 4um, and the particle size distribution is uniform, but the production capacity is low.

超微粉碎机工作原理
Working Principle of Ultra-fine Crusher
超微粉碎机是通过粉碎盘的高速旋转,在离心力的作用下,物料经装在粉碎盘上锤头的撞击而粉碎,又被以极高的速度旋飞到周围的齿圈上,锤头与齿圈间的气流因齿面的变化通断而发生瞬时交变。物料在此间隙中受到交变应力,在此反复作用下被进一步彻底粉碎。经粉碎了的物料进入粉碎分级室,通过旋转的分级轮,由受到的空气动力和离心力作用平衡进行分级,被分离出的粗料从导流罩的内腔底部再回到粉碎室反复粉碎,从而达到细度的物料(成品)被吸入分级叶轮内,进入粉碎出料室。
Ultra-micro grinder is a high-speed rotation of grinding disc. Under the action of centrifugal force, materials are crushed by impact of hammer head mounted on the grinding disc, and then rotated to the surrounding gear ring at a very high speed. The air flow between the hammer head and gear ring changes instantaneously due to the change of tooth surface. Material is subjected to alternating stress in this gap, and is further thoroughly crushed under this repeated action. The crushed material enters the crushing and classifying chamber, and is classified by the rotating classifying wheel, which is balanced by the aerodynamic force and centrifugal force. The separated coarse material returns to the crushing chamber from the bottom of the inner chamber of the guide hood and is crushed repeatedly, so that the fineness of the material (finished product) is absorbed into the classifying impeller and is crushed out.

粉碎与分离是粉碎机的主要功能,也是影响粉碎效率和能耗的关键因素。根据国内外对粉碎原理的研究可知,锤头的外形尺寸、锤头与齿圈齿间的间隙、分级效果的好坏等都会对粉碎效率与能耗有显著影响。
Crushing and separating are the main functions of the crusher, and are also the key factors affecting the crushing efficiency and energy consumption. According to the study of grinding principle at home and abroad, the shape and size of hammer head, the gap between hammer head and gear ring, and the classification effect will have a significant impact on grinding efficiency and energy consumption.
超微粉碎机结构原理
Structural Principle of Superfine Crusher
超微粉碎机由机座,转鼓,粉碎切刀,细粉捕集器,传动系统等部件组成。该机为立式转鼓结构,魔芋粉原料采用绞龙上料的方式,当物料进入粉碎腔体后在负压风机作用下呈涡旋沸腾状,转鼓在主动力驱动下,粉碎切刀高速旋转与沸腾状魔芋粉相交做高速切割,切割后的魔芋粉在细粉捕集器的作用下达标的魔芋粉进入旋风分离器分离出料,不达标的魔芋粉继续做高速切割直至达到需要的细度后才进入旋风分离器被分离出料。
Ultra-micro grinder consists of base, drum, grinding cutter, fine grinding trap, transmission system and other components. The machine is a vertical drum structure. Konjac flour is fed by a winch. When the material enters the crushing chamber, it boils like a whirlpool under the action of a negative pressure fan. Under the driving force of the drum, the crushing cutter rotates at high speed and the boiling Konjac flour intersects with the boiling Konjac flour for high-speed cutting. The cut Konjac flour acts as a fine powder collector. The standard konjac flour enters the cyclone separator to separate the material, and the substandard konjac flour continues to cut at high speed until the required fineness is reached before entering the cyclone separator to separate the material.
