As a common stone washing equipment, the spiral stone washing machine and the large amount of sand and gravel de-sludge and screening operations by hydropower, can also be used for ore sorting operations, and have been widely used in engineering and other fields!
The spiral stone washing machine can separate the dirt and ash powder on the material into clean materials. The machine has the advantages of simple structure, easy maintenance, and high washing efficiency.
The copper ore spiral washing machine is composed of a tank body, a speed reducer, a motor, a central shaft, a spiral blade, and a bracket. The bracket is welded on the central shaft, and the spiral blade is mounted and then pressed with bolts so that the blade does not sag and does not deform.
The dust and impurities are separated from the sand and passed through the spiral blade to achieve the purpose of filtering the water to remove impurities. The machine rotor adopts a central structure, and the spiral blade is mounted on the central shaft and is connected to the central shaft by the reducer for work. An apparatus for mechanical classification by virtue of the fact that the specific gravity of the solid particles is different and thus the rate of sedimentation in the liquid is different.
Flotation of disseminated copper ore generally adopts a relatively simple process. After a period of grinding, the fineness-200 mesh accounts for 50%~70%, 1 rough selection, 2~3 times selection, 1 ~2 sweeps. If the particle size of the copper mineral is relatively fine, a stage grinding process may be considered. Most of the concentrating plants that deal with the porphyry ore are re-grinding with coarse concentrates – a selective stage grinding process, which is essentially a mixing-priority flotation process. After a rough grinding, rough selection, sweeping, and then re-grinding the coarse concentrate to obtain a high-grade copper concentrate and sulfur concentrate. Rough grinding fineness – 200 mesh accounts for about 45% to 50%, and regrind fineness – 200 mesh accounts for about 90% to 95%.
