  • Publication number: 20230339002
    Abstract: A grinding-type solar module recycling equipment having a platform, a grinding blade and a negative pressure collector. A solar module is placed on a solar module placement area of the platform and the grinding blade is controlled to touch and grind the solar module layer by layer. The powders ground from different layers of the solar module is separately and immediately recycled by the negative pressure suction head. Therefore, the powders do not fall around. The grinding-type solar module recycling equipment not only does not generate secondary pollutants, but also has high purity of powdered recycled materials, which is convenient for subsequent utilization.
