我国具有丰富的硅质资源,除了具有大量高质量的石英岩、石英砂岩以外,还有大量的天然硅砂资源。用这些天然硅砂代替石英岩及砂岩,应用于玻璃、陶瓷、铸造、冶金等工业领域,不仅可以节约能耗,消除块岩破碎造成的硅尘危害,而且因其粒度均匀、粒形圆滑,可以满足玻璃、铸造等工艺 Our country is rich in siliceous resources, in addition to a large number of high-quality quartzite, quartz sandstone, there are a lot of natural silica sand resources. Use of these natural silica sand instead of quartzite and sandstone, used in glass, ceramics, casting, metallurgy and other industrial fields, not only can save energy consumption, eliminate the damage of silica dust caused by block rock crushing, but also because of its uniform grain size, smooth grain, you can Meet the glass, casting and other processes
