In recent years, China’s rapid economic development is obvious, although there are some obstacles and negative factors in the development process, we have overcome them, and the pace of modernization of our country will not stop. On the issue of housing, roads and water conservancy construction, sand and gravel attract people's high attention again. In addition, it is understood that with the increasing use of natural sand, sand can not meet the needs of economic development, coupled with the higher quality requirements, artificial sand making research and development is imperative.
Sand making machine demand is increasing every year, this is the trend of the world economy, but also that Sand really brought benefits to the community , so that it will be more widely applied. Currently, many of the sand maker manufacturers are required to find a new direction of development, an overview of the development of the situation in the various sectors , the industry is undoubtedly sand Sand future development of the industry.
Sand's working process is divided into coarse crushing, medium crushing and tertiary crushing, and sand particle shape and ultimately particle are important technical indicators used to measure the quality of the sand material. For example, in order to improve the strength of concrete, not only has request for concrete aggregate particle size, but also the shape of the material is a cube. Granular limestone used in steel-making should be kept within a certain range, and there should be no powder or small powder.
Man made sand refers to the sand is made through the process of artificial sand maker. This type of sand can be used instead of natural sand; it is more suitable for the requirements of the construction industry. Artificial sand production can be produced according to specific requirements, since this is a different production requirement for the production of sand and having different shapes and sizes.
