Designed to convey granular products, like silica sand used in the foundry industry.

该产品旨在输送颗粒物品，如在铸造行业使用的石英砂。

The basic ingredients in glass, including silica sand and soda ash, are found almost everywhere.

玻璃的基本原料，包括硅砂和纯碱，几乎可以在任何地方找到。

Such as Natural Dolomite stone, River Sand, Silica Sand, Construction Sand, Quartz stone and much more.

如自然白云石石料，河砂，石英砂，建筑砂，石英石等等。

Thus, the mineral crystalline morphology of natural silica sand is an important parameter for use in foundry.

考查了铸造用天然硅砂的矿物晶体形态，可将其大致分为单晶体和多晶集合体两类。

The center pipe is machined from 64mm tubing, and the sand filter is made from silica sand, cement, additive.

滤砂器是根据不同技术标准筛选不同粒度的石英砂、油井水泥、添加剂和水按配比加工压制的。
