The basic principle for rod grinding is reduction by line contact between rods extending the full length of the mill, resulting in selective grinding carried out on the largest particle sizes. This results in a minimum production of extreme fines or slimes and more effective grinding work as compared with a ball mill.

The Goldilocks Approach. There's a healthy demand from industry for 3D-printed cutting tools made from WC-Co, Wilms said. Aside from eliminating significant amounts of subtractive manufacturing (such as grinding) associated with traditional processes, 3D printing offers the possibility to manufacture tools to near-net shape.
This paper presents a dry grinding and carbonated ultrasound-assisted water leaching (CUAWL) process for recycling the black mass of spent lithium-ion batteries constituting anode material (graphite) and different cathode material combinations (LiCoO 2, LiMn 2 O 4, and LiNiO 2).The inspiration of the method is to enhance selective Li 2 CO 3 recovery and reduce energy requirements for ...

Avoiding remounting the dentures on articulator and selective grinding leads to, 1) A deformation of underlying soft tissues, 2) Discomfort, and. 3) Destruction of the underlying supporting bone. Later occlusal errors may be concealed and impossible to locate and correct because of distorted and swollen tissues.
A method and apparatus for selectively sintering a layer of powder to produce a part comprising a plurality of sintered layers. The apparatus includes a computer controlling a laser to direct the laser energy onto the powder to produce a sintered mass. The computer either determines or is programmed with the boundaries of the desired cross-sectional regions of the part.
