Mixed density medium double-plastid vibration mill with convex springs without join of cycles

Abstract

The invention provides a mixed density medium double-plastid vibration mill with convex springs without join of cycles. The vibration mill comprises a main vibration system and a vibration isolation system; the main vibration system comprises a vibration motor controlled by a frequency converter and used as an excitation source, and a milling cylinder fixed to the vibration motor; an upper plastid is made up of the vibration motor, the milling cylinder and an upper plastid plate, and one end of a lower plastid is connected to a main vibration spring set; the lower plastid is connected to the vibration isolation system through the main vibration spring set; the vibration isolation system comprises isolation springs connected to the other end of the lower plastid, and each isolation spring is connected to a foundation through a base; and the main vibration spring set is composed of a plurality of convex coil springs without join of cycles, and each spring is formed by winding a steel wire. The vibration mill provided by the invention has the characteristics of ultrafine particle refinement, disaggregation, narrowing of powder product distribution zone, low energy consumption, high grinding efficiency, high energy utilization rate, effective energy storage, energy saving, stable operation, obvious noise reduction, good vibration isolation effect, etc.
