In addition, other areas are also rich in pebble resources, including Henan, Shandong and Liaoning in the north, and Guizhou, Chongqing and Guangxi in the south, each with its own characteristics and rich varieties.
Among them, due to historical reasons, the pebble resources in Guizhou and Guangxi are well preserved and rich in species.
There are many large pebbles in southwest China, which are large in size and strange in shape, and are especially suitable as geomantic stones or cultural stones in landmark buildings.
There are a lot of pebbles in Henan province in the middle reaches of the Yellow River, including seasonal pebbles, granite pebbles and miscellaneous pebbles. Among them, timely pebbles account for about one-fifth of the total. Only Jiyuan City, Henan Province and Mengjin County, Luoyang City have timely cobblestone reserves exceeding several hundred thousand tons. They are pure in texture, relatively dense and smooth and delicate in surface. After selection, they can be used as grinding media for large-tonnage ball mills. Their high grinding efficiency and low cost are worth it.
