In recent years, in our artificially impact processing got increasingly widely. stone production line is mainly composed of vibrating feeder, jaw, impactor, making pressure-blasting machine, vibrating screen and belt conveyor, washing sand machine etc equipment composition. Our artificially sand production technology development can be roughly divided into three stages: groping stage, mature stage and constant innovation of wide application stage.
Our artificially impact application the beginning in the 1960s the construction of MaoTiaoHe hydropower station at the beginning of guizhou, the poor performance of the production of artificial sand hammer crusher, and on a smaller scale. 65 years yingxiuwan project built production capacity for 160t/h artificial sand system (hereinafter referred to as "artificially sand system"), Slate then pulled open our artificial stone production technology research, application prologue.
At that time, in the domestic production of artificial impact and application is still in the blank, how to artificially sand system of technological process design, equipment selection and how to improve the sand product quality and reduce production costs, etc, it is to should be in the practice exploration problems, artificially sand technology research into a lengthy exploration stage, this one phase continue supremacy in the late 1980's. During this period, a large artificially sand system mainly have wujiangdu, manwan and five strong creek sand system, etc.
After nearly 20 years of exploration, artificial sand technology has made some achievements, but still not mature, especially system design still exist many defects, such as process design USES a single fixed mode: spinning back the crushing crusher, cone crusher finely mainly adopts; Rod milling machine wet sand etc, finished materials of the gradation adjust ability is not strong. On the other hand, after this period production practice, the various try, gradually solved practical encountered many technical problems, such as granite and quartzite contour SiO2 content of equipment supra-normal wear rock for our country and more extensively applied artificially impact established, accumulated experience.
After the nineties, accelerate hydropower development, the xiaolangdi, Sandstone, ertan, three gorges, batch of oversize dachaoshan, vladimir construction of hydropower project, the mature for artificial sand technology provides a golden opportunity. Xiaolangdi project even the land sand system, design processing ability after 700t/h (1000t/h) expanded reach for LiaoYuan quartz sandstone, the average level HeLuanShi, SiO2 is 76%, highest compressive strength of domestic 351MPa, globe already built engineering material of impact the hardest of processing for processing equipment, the abrasion serious. But because the system adopted international famous manufacturer henan dawn heavy industry technology Co., LTD specializing in xiaolangdi this hard broken Limestone design sand blasting equipment, grinding according to different particle size adopt different crushing equipment to multistage crush, and adopts the flexible production technology arbitrary cycle, not only ensure the normal running of the system, and create the 595h peak average monthly running time the country's highest record.
