Hengyang glass sand washing plant is is to produce ultra-white Photovoltaic glass quartz sand and float glass quartz sand,The particle size and chemical composition requirements of two kinds of glass quartz sand are as follows:
| Item | SiO2(%) | Fe2O3(%) | Al2O3(%) | Size |
| Photovoltaic glass quartz sand | >99.5 | <0.01 | <0.3 | 0.1-0.6mm>90% |
| Float glass quartz sand | >98.5 | <0.08 | <0.8 | 0.125-0.71mm>90% |
The requirements for raw materials to produce glass quartz sand
There are two main raw materials for producing glass quartz sand, one is lump quartz stone, the other is natural granular silica sand, two kinds of raw materials through a series of processing technology, can produce glass sand to meet the requirements.
Processing flow of glass quartz sand
The quartz sand processing flow should go through all or part of crushing - screening - grinding - classifying - scrubbing - desliming - gravity separation - magnetic separation - flotation - dewatering. If the raw material is granular silica sand, there is no need for crushing and grinding, and it can be directly sent into the subsequent production process. The main purpose of quartz sand processing is to remove clay and other impurities, improve the content of quartz sand, reduce the content of Fe2O3 and impurities, and control the particle size in a certain range. Different raw materials, the use of processing technology will be different, typical glass sand production processing flow is shown as the following figure.
