金属分离器在反击式破碎机的应用

为减少金属异物对破碎机板锤、反击板、研磨腔牙板等高铬合金材质的耐磨件造成的严重损坏,安装金属探测仪和在线金属分离器对原料的硬质金属杂质进行剥离。分离器应用表明,确保了破碎机板牙等易损件达到正常使用寿命,减少了设备维修、设备维护的运行时间,降低运行成本约5%。

入辊压机物料金属异物的清除措施

为了彻底避免金属异物进入辊压机对辊面造成损伤,将普通除铁器升级为高性能除铁器,将除铁器前一组的槽型托辊改为平行托辊,安装了金属分离器。这些措施,不仅能将所有磁性金属暴露清除,还能清除非磁性金属物块。

提高碎玻璃质量的最新系统

20多年以来,玻璃工业一直是朝着回收这个方向发展。这段时间内玻璃的回收量持续增长。例如1974年联邦德国容器玻璃工业中使用的玻璃仅有6.5％是回收玻璃,到今天已增长到75％,超过了270万t。电视监视器和荧光管玻璃的回收量近几年也显著上升。在工业和家用领域有目的地收集玻璃是回收率上升的主要原因。此外,玻璃回收公司也不断地采用最新工艺满足玻璃生产厂商的高要求。 即使最细小的硅晶或者陶瓷、结石和瓷器颗粒等杂质,一旦残留在成品上,所导致的损失也会较大,引起用户索赔。

水泥粉磨系统中新技术设备的应用实践

由于原水泥粉磨系统中存在物料含金属异物、冷却水水质差、液力耦合器维护困难、隔仓板及出磨篦板易堵塞磨况差等问题,通过应用金属自动分离器、连续式砂滤一体化净水器、限矩型永磁耦合器、新型隔仓板及出磨篦板等新技术设备,保障了水泥粉磨系统安全稳定连续运转及技术指标提升。

Pressure Oxidative Leaching of Complex Sulphide Concentrate

The presented results are related to the leaching of Pb-Zn-Cu-Fe sulphide concentrate, obtained from barite-sulphide ores, under the elevated temperatures and pressures in an autoclave. The leaching process was performed using the sulphur acid solution with the oxygen addition for the separation of the targeted metals from the polymetallic concentrate. In this process influences of various parameters were discussed and then correlated to the leached metals, zinc, copper and iron. Zinc, copper and iron were dissolved in a solution, while lead remained as insoluble in the leach residue. The best leaching results were determined under the temperature of 210 ℃ during the 240 min. Obtained leaching degrees were 98% zinc, 95% copper and 96% iron.
