振动磨是一种粉磨设备。它是由作振动运动的装有研磨介质的磨筒及其支承弹簧所组成。振动运动的产生可由传动轴上偏心锤的激振力矩引起,或是由磨筒周围的电磁铁的作用引起,振动磨由于它的振动强度rω~2(r—半振幅,毫米;ω—用弧度表示的角速度,其值为n转/分×2π)可达3～10g(g为重力加速度),而球磨机仅为1g,振动磨的撞击次数又为球磨机的4～5万倍,故振动后的效率极高。目前,国外已广泛用于磨矿、粉末冶金、化学工业、医药工业、建筑材料、食品工业等各部门。其粉 Vibration mill is a grinding equipment. It is made of vibrating motion grinding medium containing grinding drum and supporting spring. The vibration movement can be caused by the exciting moment of the eccentric hammer on the transmission shaft or caused by the action of the electromagnet around the grinding drum. Because of its vibration intensity rω ~ 2 (r-half amplitude, mm; ω- The angular velocity expressed in radians, the value of n rev / min × 2π) up to 3 ~ 10g (g is the acceleration of gravity), while the ball mill is only 1g, the number of vibration mill impact and ball mill again 4 to 50,000 times, so the vibration After the high efficiency. At present, foreign countries have been widely used in grinding, powder metallurgy, chemical industry, pharmaceutical industry, building materials, food industry and other departments. Its powder
