Technical Problem

[0003]然而，相关技术中的研磨机在研磨过程中，研磨介质易从研磨腔内逃逸并与研磨机内部其他部件接触，进而对相关部件产生较大磨损

Benefits of technology

[0019]本申请实施例提供了一种研磨机，包括研磨壳体、筛分装置和搅拌装置。研磨壳体具有研磨腔、出料孔和搅拌腔，出料孔位于研磨腔的顶侧，且搅拌腔通过出料孔与研磨腔连通，搅拌腔和研磨腔之间形成有经过出料孔的物料流动路径。筛分装置设置在出料孔处，以限制研磨介质沿物料流动路径流动。搅拌装置的至少部分区域位于搅拌腔内，以对搅拌腔内的物料进行搅拌。由此，一方面，通过筛分装置限制研磨介质的流动方向，能够防止研磨介质随物料进入后续流程，降低研磨介质与研磨机内部的其他部件接触发生磨损的概率，进而延长设备的使用寿命。另一方面，通过上出料的方式，能够降低物料在出料孔堆积造成出料孔堵塞的风险，从而提升出料效果。

Abstract

The embodiment of the present application provides a grinding machine, which comprises a grinding shell, a screening device and a stirring device. The grinding shell has a grinding cavity, a discharge hole and a stirring cavity. The discharge hole is located at the top side of the grinding cavity, and the stirring cavity is communicated with the grinding cavity through the discharge hole. A material flow path passing through the discharge hole is formed between the stirring cavity and the grinding cavity. The screening device is arranged at the discharge hole to limit the flow of the grinding medium along the material flow path. At least part of the stirring device is located in the stirring cavity to stir the material in the stirring cavity. The grinding machine provided by the embodiment of the present application can reduce the probability of wear caused by the contact between the grinding medium and other components in the grinding machine, thereby prolonging the service life of the equipment.
