Fan-shaped chutes and conical concentrators work in the same way and are all fixed bevel chutes. They are mainly used for sorting beach sand mines or land sand mines. The fan-shaped chute is simple in structure, easy to manufacture, and some uses it to recover heavy minerals from the tailings sand of the tailings pond of the concentrator.
The beneficiation of fan-shaped chutes and conical concentrators has the following characteristics: 1)
Large processing capacity. The production capacity per square meter of floor space can reach hundreds of kilograms to several tons
. For example, the specification is 300mm ×
13mm ×
1000mm The single-slot treatment capacity of the fan-shaped chute is 0.9
to 1.4 t/h
; the processing capacity of a four-section conical concentrator with a weight of 2.5t
can reach 60
to 75 t/h
, so it is suitable for processing a large amount of ore and low grade. ore. 2) The
concentration of the ore is high, ranging from 50%
to 70%
, thus saving water. 3) The
operating cost is low, the equipment itself has no moving parts, and does not consume power and chemicals. 4) The
enrichment ratio of a single selection is low, and it is difficult to produce the final concentrate. To overcome this shortcoming, several fan-shaped chutes or conical concentrators are often used in combination. 5) The
selected particle size range is wide, which is 3
~ 0.1mm However, the recovery of fine-grained grades is less effective. Inflatable Drink Holders Floaties
