对石灰石原砂的质量评定,应包括哪些内容才算完备呢?过去我厂订有自己的厂标,供原砂进厂时验收用。这主要是从粒度、粒形、耐辗性(或称综合强度)吸水率、化学成分等方面提出要求。但即使指标均符合要求。往往工艺性能仍不理想,甚至差别很大,因此有必要补充新的内容。(一)石灰石是石灰石砂的原料,将石灰岩经合理机械加工,就能得到所需石灰石原砂。选用组织结构及矿物成分符合要求的石料来生产石友石原砂这点甚为重要。
Quality assessment of limestone original sand, what should be included is complete? In the past my factory has its own factory standard, for the original sand into the factory acceptance. This is mainly from the particle size, grain shape, anti-rolling (or composite strength) water absorption, chemical composition and other aspects of the request. But even if the indicators meet the requirements. Often the process performance is still not ideal, and even very different, it is necessary to add new content. (A) limestone limestone sand is the raw material, the limestone by reasonable mechanical processing, you can get the required limestone original sand. It is important to choose the stone that meets the requirements of the organizational structure and mineral composition to produce Shiyoushiyuan sand.
