Sample preparation system

The invention relates to a sample preparation system. The system comprises a grinding mechanism for grinding samples to be machined, a screening and weighing mechanism communicating with a grinding discharge port of the grinding mechanism through a screening feed port thereof and used for screening and weighing qualified samples and returning unqualified samples to the grinding mechanism, and a reduction mechanism for reducing the qualified samples according to a set reduction ratio. The sample preparation system integrates grinding, screening, weighing and reduction to realize automatic sample preparation. 本发明涉及一种样品制备系统，该系统包括：研磨机构，用于对待加工样品进行研磨处理；筛分和称重机构，其筛分进料口与所述研磨机构的研磨出料口连通，用于筛分合格样品并称重，不合格样品返回所述研磨机构；和缩分机构，用于根据设定的缩分比例，对所述合格样品进行缩分处理。该样品制备系统其集研磨、筛分、称重、缩分为一体，可实现自动化制样。
