subject: Different Spiral Grader Size, Different Application [print this page] Spiral concentrator is used as a dressing production line equipment with unique design, large capacity, wide applicable operations and is commonly used in washing ore, wash the sand off the mud, sorting grading, often referred to as spiralwashing machine.Spiral concentrator is used to select a sub-placer, such as iron ore, tin, tantalum, niobium ore.The aircraft generally used for roughing operations can also be used to deal with magnetic separation and flotation tailings from the recovery of heavy minerals. The most appropriate treatment of ore particle size limit of 3-4 mm, and the lower limit of 0.07 mm.
Spiral grader is suitable for the processing of alluvial placer, especially for the high degree of separation of useful minerals monomer, and is flat. Residual slope deposits placer intergrowth, then the recovery rate is low. In addition, the mud higher ore will reduce the quality of concentrate. So only after desliming and grading , it can be sent into the spiral concentrator.
Spiral concentrator is used for handling cassiterite, scheelite, chromite, ilmenite, zircon and monazite and other minerals, heavy minerals can also be used in the recovery of flotation tailings. Generally use it as a rough selection of equipment, you can waste most of the tailings and coarse concentrate.
Spiral ore washing machine, dressing machine advantages, disadvantages:Aircraft advantages are simple structure, easy operation and maintenance, high productivity, to adapt to the performance of large Concentrate quality and recovery rate is less obvious, change to the amount of ore to the ore concentration within a certain range. The drawback is that flaky ore separation is ineffective.
