Comco公司以特殊結构的装置构成有效的湿式分級設备。构成設备的每一台裝置(水平浓密机、弯曲管状分級机、双錐浓密机及水平淘洗机)都以相似的原理进行工作。但是,每一台装置在分級30微米到6毫米的物料时所完成的分級任务各不相同。根据該公司介紹,这种設备是为生产混凝土砂、鑄造砂、玻璃砂、磨料、粘土和其它細粒物料而設計的。第一种組成装置——水平浓密机,用于从原料泥浆中分离出大量的水,浓密后的矿浆給至弯曲管状分 Comco Corporation makes use of specially structured devices to make effective wet grading equipment. Each of the devices that make up the equipment (horizontal thickeners, curved tubular classifiers, double cone thickeners, and horizontal panning machines) all work on a similar principle. However, the grading tasks performed by each unit when grading 30 microns to 6 millimeters vary. According to the company, the equipment is designed for the production of concrete sand, foundry sand, glass sand, abrasives, clays and other fine-grained materials. The first component, a horizontal thickener, is used to separate a large amount of water from the stock slurry, and the dense slurry is fed to a bent tube
