In this paper, the dewatering and screening process of vibrating-dewatering screen is studied by combination simulation test physical experiment. The model established method computational fluid dynamics (CFD) discrete element (DEM). Subsequently, efficiency processing are defined as evaluating indexes for performance screening. Four parameters amplitude, vibration frequency, vibrating directio...

key factor in the successful application of a tunnel boring machine (TBM) in tunneling is the ability to develop accurate penetration rate estimates for determining project schedule and costs. Thus establishing a relationship between rock properties and TBM penetration rate can be very helpful in estimation of this vital parameter. However, this parameter cannot be simply predicted since there ...
