Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand preparation, in particular to a high-purity quartz sand preparation device. Background Art

[0002] Quartz sand is quartz particles made by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, chemically stable silicate mineral, whose main mineral component is SiO2. Quartz sand needs to be hot-melted to become high-purity quartz sand. Hot melting will melt it into large blocks of high-purity quartz sand. In order to achieve the particle size required for later processing, it needs to be crushed. However, existing crushing devices generally do not have a screening function, resulting in quartz sand of different sizes after crushing, which cannot meet processing requirements. It is necessary to use an external screening device for screening and then repeat the crushing. This process takes a lot of time and reduces processing efficiency. Therefore, a high-purity quartz sand preparation device is proposed to solve the above problems. Utility Model Content
