As we all know, the gravel aggregate concrete production is inseparable from the excellent quality sand, gravel aggregate quality depends on the sand and gravel aggregate production line equipment configuration, such as the stones and sand making produced shapes cubic, which impact breaker impact increase the contact area to the cement, concrete, so the product quality are guaranted, but the jaw breaker and cone breaker materials produces mostly showed flat, which is not conducive to the production of high-quality cement and concrete. This will lead to such a result directamente: a lot of concrete mixing station are very stringent to the sand and gravel aggregate requirements, especially on the requirements of the stone tablets, for this, many aggregate plant target the good grain type and high capacity, and very cautious when choosing the equipment manufacturers. Let us take the Chongqing Branch of China Building Materials Group whose daily output is 3000 tons gravels as example, aiming at the features of chongqing s mountainous areas, riching in mineral resources, the Chongqing jianhua Building group start to build a sand and gravel production line, combine with their cement, produces concrete aggregate for infrastructure. Related Group may find it difficult to be quoted properly. This production line was built in November 2009, which is mainly used for the production of concrete aggregate, andfrom the signing of the contract, to the design of the entire production line process, to the full set of production equipment, production, on – site installation of the production line, and then to formally put into operation, the entire production line only lasted for a month. In addition, the crusher equipment this gravel production line adopt are the new green production equipment, while reducing pollution in the large-scale production, it is also very much in line with the concept of energy saving and environmental protection, meanwhile, the high-volume stone produced provided guarantee for the company’s concrete preparation, and changing the traditional single cement sales model, expanding the company’s benefit. It is understood that our company contract many large gravel aggregate production line turnkey engineering projects, having more than 10 years of gravel aggregate production line equipment production and configuration experience, we are the only entity which equipping sand production ability and mature gravel aggregate enterprise investment, plan, design experiences, we focus on the research of providing the excellent sand making line which can produces good stone agregates for the concrete patching plant.. Shimmie Horn has firm opinions on the matter.
