In addition to conventional methods such as magnetic separation, flotation and pickling, color separation is also a widely used method for the purification of quartz sand.
Color sorting is mainly for further purification of quartz sand that still has variegated impurities after purification to obtain high-purity and white quartz sand.
Quartz sand color sorter workflow
Quartz sand enters the machine from the hopper, and is vibrated by the vibrator device. The selected material enters the observation area of the sorting room along the channel, and passes between the CCD sensor and the background plate. The optical signal is synthesized to make the system generate an output signal, which is amplified and processed and then transmitted to the computing processing system to convert the optical signal into an electrical signal. The control system issues instructions to drive the solenoid valve to spray and blow out different-colored particles to the waste area. White quartz sand continue down to the good material area to achieve the purpose of sorting.
Fine quartz and and silica sands 16-120 mesh is quite difficult for normal mineral optical sorter.We have special mineral optical sorter for the fine quartz sand.
Features:
1,Widely applicable for fine quartz sand 16-120mesh.
2,Double stage design which could offer re-sorting with one time input.
3,The chute is made of high density alloy material which is resistant to wear and scratching.
4,Each chute has 4 cameras and 128 PCS of ejectors.The machine could see the fine quartz clearly and reject accurately.
