spiral washing machine
Spiral washing machine separates ores according to the law of ore motion in the inclined water flow. There are two kinds of spiral washing equipment: spiral washing machine and spiral sluice. for the spiral washing machine is used to separate size of 0.3-1mm without classifying or wide-granularity-range. And its best feeding size is 0.1-1mm. Spiral sluice is mainly for the fine material of 0.02-0.5mm.
Spiral washing machine in mainly used in alluvial sand beneficiation of tin stone, ilmenite, monazite, rutile, zircon, chromite, tantalum niobium ore while sometimes it is used in the quartz ore separation or nin-metal ores. And it can be also used to recovery metal from floatation separation tailings.
Spiral washing machine is kind of gravity separation machine starting from 20 or 30 years ago, and at this moment it has been iused in beneficiation of fine iron lean ore.
Spiral washing equipment is usually working in the rough separation to get the rough concentrate while sometimes it is used in the fine selection of the coarse concentrate to gain high-grade concentrate.
The advange of spiral washing machine: 1) no power 2) no lunrication 3) no noises 4) low water-consumption 5) simple-structure and easy to operate 6) compact allocation and short trasportation 7) easy to maintain and human-power-saving 8) low requirements about the feeding concentration, fedding capacity, feeding granularity 9) reliable working and low failure
