Research on Crushing Concrete Members by High-Voltage Pulse

High-voltage pulse discharge (HVPD) is an energy-saving, efficient, and green technique, which has broad prospects in concrete crushing. The finite element models of the concrete beam, slab, and column segments were established with ANSYS/LS-DYNA finite element software. Based on the principle of equal impact pressure, the Safe and effective rock crushing is of great significance in municipal, mining and hydropower projects. At present, common rock fracturing technologies mainly include hydraulic fracturing, high-pressure gas blasting and explosive material blasting, etc. (Changyou et al. 2017; Hou et al. 2017; Zhang et al. 2019a).Hydraulic fracturing Research and Application of High-Energy Gas Fracturing

Rock Crusher History-TY Industrial Technology Group

With the continuous development of productivity, jaw crusher cannot fully meet the needs of crushing technology. Therefore, people have designed a more efficient impact crusher. The development of impact crusher can be traced back to the 1950s, when the structure of the crusher was similar to that of the modern squirrel cage crusher, it When the shock wave in the confined medium with the vicinity of the explosive first impacts on the wall surface of the borehole, the strength of the induced rock shock wave far exceeds the dynamic compressive strength of rock and the borehole surrounding rock is subjected to intensive compressive damage [10].Hard rock is Rock-breaking mechanism and experimental analysis of

Influence of Natural Aggregate Crushing Process on Crushing

Crushing is one of the most energy-consuming technological processes. The purpose of grinding is to achieve the desired grain size of mineral raw materials. The process of grinding consists of many factors, for example, the size and form of crushed grains, as well as their mutual arrangement inside the crushing machine chamber, the DEM-based models of cone crushers are gaining attention in the literature (Quist, 2012); however, their applications are limited to predicting the crusher performance from the crusher settings and feed properties in order to better understand the rock flow and breakage characteristics inside the crusher chamber and to aid in the design of new A review of modeling and control strategies for cone crushers

A review of some nonexplosive alternative methods to conventional rock

The conventional blasting rock excavation method is the main means of rock breakage because of its high productivity, and it is relatively inexpensive compared to other methods. However, it raises safety concerns and can negatively impact the environment. The major disturbances that may be induced by this method include flyrock, gas emissions, and Internationally, there have been relatively systematic studies of side-slope stability technology management and homogeneous rock mass blasting theory in deep concave open-pit coal mines.(PDF) A brief history of the development of blasting and the modern

Analysis of Dynamic Damage Fractal and Energy Consumption

According to the relationship between strain rate and crushing energy density in Table 2, the reasonable strain rate range to achieve rock crushing can be treated as the intersection of the above sets, which should be 68.14–77.61 s −1, and the reasonable crushing energy density range should be 0.65–0.98 J/cm 3 (the dashed line range in To meet the diverse requirements in processing technology, mobile cone crushing plants are available in different sizes and configurations.
