Hydraulic Coupling For Ball Mill Manufacturers Suppliers ...

Buffer protection in ball mill drive--hydraulic coupling. The barrel of the ball mill is used as the pulley of the reducer. When the ball mill is heavily loaded, the starting current of the motor can reach more than six times the rated current. In order to alleviate the mechanical impact during starting, the hydraulic coupler is added into the ...

Gram‐Scale Synthesis of a Hexapeptide by Fragment

2021-8-19  Here we show that using solvent-less methods, such as ball milling, enabled the production of the hexapeptide Boc-(Ala-Phe-Gly) 2-OBn at the gram scale with high overall yield (77 %, 5 linear steps). This is the longest peptide chain synthesized in a ball mill to date, in which the amino acid sequence is precisely controlled.
