Middle-convex doubling-free spring and mixed-density media double-cylinder double-mass vibration mill

Abstract

The invention discloses a middle-convex doubling-free spring and mixed-density media double-cylinder double-mass vibration mill which comprises a main vibration system and a vibration isolation system. The main vibration system comprises a motor. A vibration exciter shaft is connected with an outer shaft of the motor through a coupler. A machine base of the vibration exciter shaft is fixedly connected between an upper barrel and a lower barrel. A vibration exciter is installed between connection plates of an upper mill barrel and a lower mill barrel of an upper mass and used as an exciting vibration source of the whole mill. The vibration isolation system comprises a lower mass connected with a main vibration spring set. The other end of the lower mass is connected with a vibration isolation spring. The vibration isolation spring is connected with a foundation through a base. The main vibration spring set is composed of multiple middle-convex doubling-free spiral springs. Each spring is formed by winding a steel wire. The middle-convex doubling-free spring mixed-density media double-cylinder double-mass vibration mill has the advantages that ultramicro grains are refined and deaggregated, a powder product distribution belt is narrowed, energy consumption is low, powder milling efficiency is high, the energy utilization rate is high, energy is effectively accumulated and saved, operation is stable, noise is remarkably reduced, and the vibration isolation effect is good.

Description

technical field [0001] The invention relates to a grinding equipment for ultra-fine powder vibration preparation, which is a double-barrel two-mass vibration 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.
