Short CylinderBall Mill: Theball millwith the cylinder length (L) less than 2 times of the cylinder diameter, i.e. theball millwith L ≤ 2D is short cylinderball mill, which is usually of single bin structure, mainly used for rough grinding or primary grinding operation, and can realize the wide use of 2-3ball millsin series.
PROBLEM TO BE SOLVED: Since the conventionalball millpulverization method uses only pulverization heat, when the water content of silicate ore is increased, the pulverization heat alone cannot be sufficiently dried and dew condensation occurs in theball millpot. , The silicate ore, powder and balls that are the contents of themillstick to the inner wall of the pot and become stuck, and ...
Dec 01, 2010· Abstract The ball-milling technique was used under solvent-free conditions to perform a Horner–Wadsworth–Emmons reaction in the presence of a mild carbonate base. Starting from a phosphonate-substituted glycine, this method gave access to Boc-protected unsaturated amino esters in excellent yield and selectivity in many cases.
