1·Sand washing machine is coordinated with sand Maker to separate the sand from stone dust.
用于清洗分离砂石中的石粉泥土，是配合制砂机使用的一种高效洗砂选矿设备。
2·The increment of stone dust from 4.3 to 20% did not adversely affect the strength, and the abrasion loss of concretes was reduced.
随着机制砂中石粉含量从4.3%增加到20%，对混凝土强度无不利影响，磨损量逐步减小；
3·One of the most remarkable difference between manufactured sand and natural sand is stone dust whose particle size is less than 0.
机制砂中含有石粉是机制砂与天然砂之间最显著的区别之一，而石粉对机制砂混凝土性能影响也是机制砂混凝土研究的重点。
4·Exposure to asbestos, chemicals, acids, solvents, or coal or stone dust was not associated with a higher risk, the researchers said.
与石棉、化学试剂、酸、有机溶剂、煤以及石灰等接触，并没有显示出更高的患病风险。
5·While a shortage of sand resources in many states of our country, much crushed stone dust was produced in the course of crushing stones in quarry.
在我国很多地区出现天然砂资源短缺的同时，采石场加工碎石产生大量的石屑，占用场地且污染环境。
6·The tests show part of the waste stone dust instead of sand can improve workability of mortar, reduce mortar contraction and increase compression strength…
试验表明，废石粉部分取代砂，可以改善砂浆的和易性，减少砂浆收缩，提高抗压强度并有利施工。
7·Compared with nature sand, MS (manufactured sand) is characteristic of rough particle and angular, with a large amount of stone dust and lithofacies diversity.
与天然砂相比，机制砂富含石粉，颗粒表面粗糙多棱角，并且岩性多样。
8·The freeze-resistance of crushed stone dust concrete was better than natural sand concrete. The impermeability of crushed stone dust and natural sand concrete is nearly.
石屑混凝土的抗冻性较天然河砂混凝土要好，抗渗性与天然河砂混凝土相当。
9·The tests show part of the waste stone dust instead of sand can improve workability of mortar, reduce mortar contraction and increase compression strength. It is of advantage for construction.
试验表明，废石粉部分取代砂，可以改善砂浆的和易性，减少砂浆收缩，提高抗压强度并有利施工。
10·Dust and sand stone dust is not the juvenile, the clear river stones is not fun and the tears shed by green plants is not a rock fresh lover, the animals are not running stone and lively subjects?
尘埃和沙子是不是石头飞扬的幼年，清清河水是不是石头缤纷的眼泪，绿色植物是不是石头鲜嫩的情人，奔跑的动物是不是石头活泼的子民？
