Title The design and experimental verification of high-energy ball milling device
Abstract
Ball mill is the most history in grinding industry and widely used type of grinding
equipment. To develop new superfine grinding equipment has practical research
significance and broad market efficiency. In this paper, based on the structure and
working principle of traditional ball mill, grinding crushing theory, we design a
continuous laboratory using high-energy ball mill equipment, and use the existing
intermittent vibration ball mill parts verification The design of ball mill including
feeding, bearing, transmission, barrel and discharge：Ball mill using combined feed
feed and improve grinding efficiency; Use without gear belt transmission, easy
operation；Feed port and discharging port design to ensure its continuous operation,
obviously increase the production efficiency; Barrel internal lining bar, the outside has
a manhole, ensure the service life of cylinder. The design of ball mill work of N = 60
RPM, put the ball G = 0.03 T, D = 18 mm ball size; Choose YCJ100-140 w specific
gear reduction motor, transmission ratio = 4.33, I choose big pulley D = 399.5 mm,
small pulley D = 92 mm, while the design of ball mill can normal production, the
productivity of Q = 0.063 T/h. Ball mill is chosen according to the design laboratory
with intermittent ball mill for the sample Fe36.3 Ni23.6 B14.9 Si3.7 Mo3 experiment
validation, ball mill after 128 h, 51.4 nm decreases the grain size of the sample is 10.5
nm, its obvious decreases, and reached nanometer level, to verify the effectiveness of
the ball mill.
