Barrel-shaped non-running-on spring and mixed density medium side-placed type vibromill

Abstract

The invention discloses a barrel-shaped non-running-on spring and mixed density medium side-placed type vibromill. The vibromill comprises a main vibration system. The main vibration system comprises a vibration motor which is controlled through a frequency converter and used as a vibration source, at least one milling barrel connected with the vibration motor, and a counter weight body which is in flange connection with the milling barrel. The vibration motor, the milling barrel and an upper medium body frame form an upper medium body. The upper medium body is connected with a base through a spring set. The spring set is composed of a plurality of barrel-shaped non-running-on coil springs. Each spring is formed by coiling a steel wire. Each steel wire is coiled into a barrel-shaped coil structure. Each barrel-shaped non-running-on coil spring comprises at least four circles of effective screws. The vibromill has the positive, obvious and unique effects and the characteristics of particle refining, deaggregating, low energy consumption, high powder milling efficiency and energy utilization rate, effective energy accumulation, energy conservation, stable operation, remarkable noise reduction, good vibration isolation effect and the like.

Description

technical field [0001] The invention relates to a grinding equipment for vibration preparation of superfine powder of materials, which is a side-mounted vibrating mill with a convex non-coil spring and a medium with a mixed density ratio, belonging to vibration utilization and powder engineering interdisciplinary science and technology.
