一种多层行星辊磨机

Multilayer planetary roller mill

Abstract

The invention relates to a multilayer planetary roller mill, which belongs to the field of powder grinding processing equipment. In the multilayer planetary roller mill, a grinding cylinder is fixedly connected with a hollow rotating shaft, a grinder roll bracket is a multilayer connecting bracket which is axially arranged at intervals, each layer of connecting bracket is movably connected with grinder rolls through connecting chains which are uniformly arranged in the radial direction at intervals, a central rotating shaft passes through a central axis of the grinder roll bracket to be fixedly connected with the grinder roll bracket, the central rotating shaft is sleeved inside the hollow rotating shaft to be integrally arranged inside the grinding cylinder, the central lines of the two rotating shafts are overlapped, the central rotating shaft and the hollow rotating shaft are respectively connected with a power device and rotate in reverse directions, and the grinder rolls rotate in opposite directions with the grinding cylinder inside the grinding cylinder. On one hand, the grinder rolls are driven by the grinder roll bracket and affected by the friction force with the grinding cylinder to obtain a higher speed than that of the grinding cylinder, and on the other hand, multilayer and multi-angle grinding working surfaces which are formed through the grinder rolls which are movably connected with the multilayer connecting bracket, the grinding working efficiency of the materials can be adequately improved and the escaping rate of the materials can be reduced.
本发明一种多层行星辊磨机,属粉料研磨加工设备领域,本设计多层行星辊磨机其磨筒与空心转轴固定连接,磨辊架为轴向间隔设置的多层连接架,各层连接架经径向均匀间隔设置的连接链与磨辊活动链接,中心转轴穿过磨辊架中心轴线与其固定联接,将其中心转轴套入空心转轴中,整体配合设置在磨筒内,且两转轴的中心线重合,中心转轴、空心转轴两转轴分别与动力装置连接作反向转动,磨辊随磨辊架在磨筒内与磨筒相向转动,一方面,磨辊在磨辊架带动下和与磨筒的摩擦力作用下获得相对磨筒较高的速度,另一方面,多层连接架所活动链接的磨辊与磨筒形成的多层次多角度分布的研磨工作面,所以全面提高物料研磨工作效率并降低了物料的逃逸率。
