Ore sand spiral classifier fob price

The spiral classifier is widely used in the grading of the grinding circuit of the concentrator and the operations of washing, de-sludge, and dewatering. Its main advantages are simple equipment construction, reliable operation, and convenient operation. It can be self-flowing with energy-saving ball mill in the closed-circuit grinding circuit. It is suitable for wet magnetic separation of magnetite, pyrrhotite, roasting ore, ilmenite and other materials with particle size below 3mm. It is also used in coal and non-metallic minerals. Iron removal operations for materials such as building materials. It’s also named screw classifier.

Operation

The machine can only be operated after the structure and working principle of the spiral classifier are clear. After the spiral body rotates, it can start to feed ore slurry, gradually feeding the amount of ore. When the spiral body is in working state, if it encounters special faults such as jamming or overload), it must be stopped immediately, immediately lift the spiral body out of the slurry surface, never allow the spiral body to be pressed in the slurry, and quickly open the mine valve to avoid siltation. When starting again, the spiral body must be lowered to a certain position in order to rotate the spiral body. If the machine needs to be stopped during use, the feed should be stopped first, and the operation can only be stopped after the material stage is graded and there is no material in it.

Compared with the hydro cyclone, the power consumption is lower. The main disadvantages are low classification efficiency, heavy equipment, and large floor space. Due to the limitation of equipment specifications and production capacity, it is generally not possible to form a closed circuit with a ball mill with a specification of Φ3.6m or more.

Application range Mainly used in the classification of various non-ferrous metal ore dressings such as quartz sand, gold, iron, aluminum, etc. It can also be used for the classification of materials such as pulp and ore.

Processing capacity

The model of the screw classifier is different, the processing capacity is different, and the processing capacity of the spiral classifier is 30~240 m³/h.
