coal gangue sand

The machines use products out of sand, stone, coal ash, cinder, coal gangue, ore tailings, ceramic, perlite and other industrial wastes processed into a variety of new wall materials.

本机所出产品可采用砂、石、粉煤灰、煤渣、煤矸石、尾矿渣、陶粒、珍珠岩等工业废料加工成各种新型墙体材料。

On the basis of research of various physical characteristics of coal gangue, fly ash, Aeolian sand, through contrast experiment, we chose this new reinforce material.

在对煤矸石、粉煤灰和风积砂土的各项物理力学特性进行试验研究的基础上，通过对比试验选择了可供工程应用的新型固化剂。

The effects of different drawing intervaland top-coal fragmental size on flow character of coal-gangue and sand, and on mixed degree of coal and gangue were analyzed during drawing top-coal.

分析了不同放煤步距、顶煤块度对放煤过程中煤矸砂流动形态、混矸程度的影响。
