深浓密机,顾名思意就是高度大于直径的浓密机,且无耙、无任何传动部件。 目前,有一些这样的浓密机在加拿大的牙买加铝业公司所属的铝酸盐厂中,用来浓密红泥——一种从矾土中提取铝而剩下的不溶性残渣。自从四年前首次在生产中使用以来,已取得了一些关于浓密作用机理的有趣数据。与常规耙式浓密机相比,深浓密机产生的底流含水量只有常规耙式浓密机的一半。另一方面,使用在逆流洗涤流程中,可以减少溶质的逐级输送,从而可降低操作费用。
Deep thickener, as the name suggests is a thickener height greater than the diameter, and no rake, without any transmission components. At present, some of these thickeners are used in the aluminate plant owned by the Canadian Aluminum Company of Jamaica for thick red mud, an insoluble residue left after the aluminum is extracted from the alumina. Since it was first used in production four years ago, there have been some interesting data on the mechanism of thickener action. In contrast to conventional rake thickeners, the deep thickener produces less than half the underflow from conventional rake thickeners. On the other hand, the use of countercurrent washing process, you can reduce the level of transport of solutes, which can reduce operating costs.
