In this study, simple and environmentally friendly magnetic biochars were successfully prepared by ballmilling biochar with Fe 3 O 4 nanoparticles to remove NPs from water. The magnetic biochars synthesized at various pyrolysis temperatures of 300 °C (MBC300), 500 °C (MBC500), and 700 °C (MBC700) were used to eliminate the unmodified (PS), aged under UV radiation (UVPS), aminemodified (PS ...

In summary, magnetic liners enhanced ball mill performance, compared to conventional steel and rubberlined mills. At the investigated mill speeds, most abrasion/attrition was induced in a magneticlined mill where mill charge had an intensive cascading motion. Impact within the mill was diminished in magneticlined mills compared to steel ...

Ternary CePt 3 Si crystallizes in the tetragonal P4mm structure which lacks a center of inversion. Antiferromagnetic order sets in at T N ≈ K followed by superconductivity (SC) below T c ≈ K. Large values of H′ c 2 ≈ − T/K and H c 2(0) ≈ 4 to 5 T were derived, referring to Cooper pairs formed out of heavy quasiparticles. The mass enhancement originates from Kondo ...

The ball mill liners are located on the inner surface of the ball mill barrel, which protects the barrel from the direct impact and friction of the grinding media and the material. The ball mill liners' material and shape are different base on requirements. When the grinding media contacts different shapes of ball mill liners, the movement state will also change, thus enhancing the crushing ...
