Investigation of the performance of grooved grinding rods as a lifter in a laboratory rod mill [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2023
To date, there has been limited research conducted comparing the effects of various grinding media shapes on milling kinetics, load behavior, and mill power draw. However, no research has been conducted on their effects on a lifter.

Study of the Effect of the Mineral Feed Size Distribution on a Ball Mill Using Mathematical Modeling [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2021
In this paper, the effect of the feed size distribution was studied for a ball mill. Copper ore of 0.5% was tested using batch-grinding tests. Samples were carried out using three reconstructed feed size distributions in an experimental ball mill.

Breakage of Tapered Junctions of Modular Stems in Revision Total Hip Arthroplasty—High Incidence in a Consecutive Series of a Single Institution

open access: yesBioengineering, 2023
Background: Modularity in revision THA (RTHA) has become accepted during the last three decades. Nevertheless, specific risks of modularity of current revision devices such as breakage of taper junctions occur during follow-up.

Design and Experiment of Automatic Adjustable Transplanting End-Effector Based on Double-Cam

open access: yesAgriculture, 2023
In view of the plugged-out end-effector that can adapt only to a specific size of the tray, the needle spacing and angle of the seedling needle are fixed. In this paper, a new type of plugged-out transplanting end-effector is proposed.
