一、前言锤式破碎机的致命弱点是含尘鼓风量大,污染严重。其出口处室内空气含尘浓度达300~1000毫克/米~3,有的甚至高出国家卫生标准(10毫克/米_3)400倍。目前的对策是在物料出口处抽风除尘,抽风量在10000米~3/时以上,但是效果均不佳,而且增加了除尘投资,带来了运行、维护等问题。现在国内外,对破碎机内部流场规律和鼓风机理的问题研究甚少,以致还没有文献详细
First, the foreword Hammer crusher Achilles heel is the dust blast volume, serious pollution. The outlet of indoor air dust concentration of 300 ~ 1000 mg / m ~ 3, and some even higher than the national health standards (10 mg / m _3) 400 times. The current countermeasure is to exhaust the dust at the exit of the material, and the exhaust volume is above 10,000m3 / h, but the effect is not good, and the investment of dust removal is increased, which brings about the problems of operation and maintenance. Now at home and abroad, little research has been done on the law of internal flow field and blast mechanism in the crusher, so there is no detailed literature
