Comminution by gyratory crusher is the first stage in size reduction operation mineral processing. In copper industry, these machines are widely utilized, and their reliability has become a relevant aspect. To optimize design to improve availability of crushers, it necessary calculate power torque accurately. The discrete element method (DEM) been commonly used several mining applications power...

In the comprehensive development and utilization of crop straw, it is key to separate fibers in straw through a certain process or equipment. order obtain rice fiber material, crusher was designed using SOLIDWORKS software, its grinding simulated EDEM software verify feasibility machine principle structural rationality. The wheel speed, screw feed shaft clearance were used as test factors desig...

China is a large agricultural country, each year will produce number of straw. The recycling straw to China's development and environmental protection are very helpful, the mainly energy, fertilizer, feed several uses, different uses need crushing fineness, so adjust fineness can improve rate This paper on impact factors for focuses theoretical analysis study affecting crushing, provides genera...

Rough terrain autonomous navigation continues to pose a challenge to the robotics community. Robust navigation by a mobile robot depends not only on the individual performance of perception and planning systems, but on how well these systems are coupled. When traversing rough terrain, this coupling (in the form of a cost function) has a large impact on robot performance, necessitating a robust ...
