The sand and gravel aggregate in the concrete is very important, it plays a skeleton application, pass the stress, even without the grout, the aggregate can also support the load, while inhibiting the contraction to prevent cracking. Impact crusher has an irreplaceable role in the Concrete Aggregates Production.

Since the last century, 90 generations, the development trend of the concrete is the development of high-performance concrete, aggregates gradually as the main framework for the material, and the amount of cement as little as possible; impact crusher development must have a high-quality sand stone aggregate; concrete experts in China, the quality of the sand and gravel aggregate as a bottleneck restricting our concrete development; of concrete quality not as good as the the Western main reason for the poor quality of the sand, the particle size distribution of the sand and gravel aggregates, grain type, surface characteristics of needle flaky particles content, porosity, etc. in the past were not taken seriously or unable to control the performance of increasingly important. Impact crusher came into being precisely, its significant features in the above aspects, but because of the existing aggregate awareness of prejudice, but also limits the understanding of the importance of artificial sand, just as a kind of artificial sand simple replacement of natural sand material treated, measured by the standards of the traditional natural sand artificial sand, see the weaknesses are artificial sand or are not used to at artificially limit the development of artificial sand.

Henan Liming Heavy Industry Science & Technology Co., Ltd. is a professional stone crushing, artificial sand making firearms manufacturer, has launched the gravel aggregate production line machinery, can produce a variety of stone, sand, successful resolution of the concrete variety quality specifications aggregate supply problem, a steady stream of high-quality concrete gravel aggregate for highway, port construction, hydroelectric dam construction. My company for many years engaged in the production of sand and gravel aggregate machinery, through customer surveys and on-site field survey, the importance of sand and gravel aggregate, the company launched a 5X series of new impact crusher, dedicated to highway, railway gravel aggregate production.
