Recently, the main equipment for a 300,000-ton-per-year high-purity quartz sand production line designed and manufactured by Weifang Guote Mining Equipment Co., Ltd. for Southeast China has been completed. The core equipment, including drum screens, desliming buckets, hydraulic classifiers, obstructed settling machines, wet belt magnetic separators, and wet high intensity magnetic separators (WHIMS), has been loaded and shipped in batches, marking an important step forward for my country in the localization of high-purity sand equipment and the integration of complete production lines.
