在锤式破碎机中,对冲击作用破碎机(其中也包括锤式破碎机)电动机功率的计算,有一系列经验公式,以及在破碎过程的各种设想基础上确立的许多理论公式。但是运用它们却得出很不精确的结果,因此,常常有这样的现象:为成批生产的破碎机提供的电动机要么在功率因数COsφ低的情况下低负荷作业,要么由于它们的功率不足使其生产率受到限制。为此,全苏建筑及筑路机器制造科学研究所进行了一些研究工作,旨在得出一种冲击式破碎机 In hammer crushers, there are a number of empirical formulas for the calculation of motor power for impact crushers, which also include hammer crushers, and many theoretical formulas based on various assumptions of the crushing process. However, the use of them leads to very inaccurate results and, therefore, often the phenomenon is that motors provided for mass-produced crushers are either operated under low load with low power factor COsφ or because of their insufficient power Its productivity is limited. To this end, all the Soviet Union Building and Road Machinery Manufacturing Research Institute conducted some research work aimed at reaching an impact crusher
