破碎和磨矿设备目前,辊压机已广泛应用于水泥工业,它具有节能和防止过磨的优点。在碾磨水泥熟料时,当出磨物料的勃氏表面积一定时,辊压机可节能约19%(相对于传统的风扫式球磨机和圆锥式球磨机)。辊压机应用于铬矿的碾磨时,以前铬矿需在球磨机中湿磨到-74微米的颗粒占83%,然后返回去过滤,才能达到所要求的球磨湿度,而采用新研制的辊压机,只需磨到-74微米的颗粒占55%即可达到所要求的球磨湿度。
Crushing and grinding equipment At present, the roller press has been widely used in the cement industry, it has the advantages of saving energy and preventing over-grinding. When grinding cement clinker, the mill can save about 19% of energy (compared to conventional air-swept ball mills and cone-type ball mills) when the Blaine surface area of the mill material is constant. In the case of chrome mills, chrome mills were previously chilled to 83% by wet grinding to -74 microns in a ball mill and then returned to the filter to achieve the required ball milling wetting, with newly developed rolls Press, just grinding to -74 micron particles accounted for 55% to achieve the required ball milling humidity.
